Best OTS tune for 8V RS3

[M3_Dylan]

Car is currently in transport to me but i’m already doing research into tunes. I figured this topic would be beaten to death but I haven't found anything recent comparing everything out there. If people could chime in with experience and “words on the street” that would be great to compile a nice little thread of information. This car is soon to be my daily, so I'm looking for something I can put miles on everyday without a fuss.

APR - The pinnacle of OTS tunes for VAG. I know their tunes are great and they have tons of testing and history. However, I hate the idea of finding and paying a certified shop to do something I easily can in my garage. $700 ECU $500 TCU (suggested)

Unitronic - Seems to be the most popular OTS tune for this platform. Have only heard great things about it however it seems to be lacking some features. $900-1,000 ECU $700-800 TCU

IE - One of the most cost effective options however doesn't seem to be as popular for some reason. I have read that it's on par with Uni and have also heard the TCU tune leaves some to be desired. $700-800 ECU

DS1 - Newer guys on the block. Leading in innovation and E85 capabilities which is impressive. However, there are additional costs to protuning and in the end, is probably the most expensive option. I hear the OTS files they offer are pretty good as well. $1299 ECU

034 - I haven't heard much at all about their flash software. $700-900 ECU $600 TCU

GIAC - Recent release. Not much information.

DS1 is newest to this platform but we have been tuning for 20 years and writing ECU features for 15. Our tuning is in 10s of thousands of cars. You can also see and thoroughly log everything we change which means they are extremely thorough because we put ourselves to public ridicule if someone sees something nasty. We are amongst the most expensive and we do not do sales, but our features include those of standalone ECUs and still no one else does flex fuel on an OEM ECU this platform. On OTS we go for an OEM like approach to smoothness and reliability rather than drag records. Our flashing hardware is our own design and manufactured in Ohio. Our flashing software is entirely our own and often flashes twice as fast as others, without needing a laptop unless you want to use one. We do not rely on your laptop battery, your laptop not restarting or a wobbly USB cable to complete a flash and our rate of incomplete flashes is tiny. We are actively adding new features and updates are free. Please email us if you have any questions.

DS1 user here and their OTS files included run fantastic without a hiccup. The DS1 has much more flexibility than the others mentioned and the data logging software alone was the selling point to me as well as the ability to custom tune if I wish. I am also setup on flex fuel which is another huge advantage as i can just pull up to any e85 station and fill up and not touch a thing with my tune as it will automatically adjust based on the ethanol content the sensor reads which is extremely convenient.

GIAC has also released their tune, they have also been in the game for 20 plus years, roughly the same gains as everyone else, ~100ftlbs, 75hp give or take.

APR - Only offers stage 1 or stage 1 APR plus (includes warranty from APR -- have even heard of people getting water pumps replaced through them), no option to go stage 2 so if you may eventually go that route this is not going to be for you. One of the benefits though is since they stopped offering stage 2 tunes, their tunes are heavily discounted. You can get ECU and TCU tune for much less than the competition. Very conservative and therefore low risk, but you give up a lot of potential compared to other tuners (of course whenever you tune there is going to be risk even on a conservative tune).

Unitronic - Definitely most popular, they have put the most time into development on this platform for OTS. Great tune, will eventually (supposedly...lol) have flex fuel and few other nice features.

IE - I haven't seen too many people running it and haven't heard much, so can't give any input. Maybe I just haven't noticed. I know they are fairly popular on the 2.0T (S3)

DS1 - Great features, but with custom tuning cost does add up a bit (once Uni flex comes out we'll see how the cost compares). Me personally don't think its the best option just to go stage 1 or 2 unless you are trying to do something out of the ordinary or desperately need flex fuel due to the area you are in and not willing to wait for Uni. Down in South Florida are E is very consistent and I see about E70-80 at every station, usually on the higher end of things. Since you are in Ohio I imagine you'd benefit from flex fuel for the winter. One of the biggest benefits of it is being able to custom tune and having some neat features like showing E content on the virtual cockpit.

034 - Haven't heard much either, but they do make some good products overall. Have had their stuff on several cars and been very happy with them, but never a tune.

[lemonvr6]

APR low risk? Interesting

[carlosvjr92]

APR low risk? Interesting

Seems to be the general consensus. I've only seen one car have an issue that I know of. I have APR, but definitely not my first choice. Was on the car when I got it and I have had 0 issues.

[Fixeroh]

I'm only familiar with APR. I live east of Cbus but there is a well qualified APR tuner on the west side of Columbus. As I'm not constantly flashing or reflashing the ECU, the drive was not an issue. Guy knows his stuff; racing shop. Used APR for my 2015 S3 up to stage 2+. Stage 1 93 octane on my current 2018 RS3. Same shop did my TCU tune as well. Stage 1 is quite sufficient for my current needs. Car is my daily driver and I do not track it. it's been flawless and is stupid fast. Low miles however as I've been teleworking considerably the past year and a half. It's nice that there are several tuning choices. I can confirm APR has been good to me. I'm not concerned about tuning from my own garage. After my 4 year maintenance June 2022, will let my dealer (Byers) connect to the system to cover all recalls, etc. One concerns the ECU. Assume I will have to reflash my ECU after that maintenance trip. Will be flagged TD1 at that point but essentially at the of the primary warranty period. Good luck with your decision!

[DrMerl]

034 Motorsport S2 E85 with 034 TCU here. I've been a gear head since the 80s, got to know tuning starting with mechanical Jetronic systems, learned a lot from ECCS/Nismo gurus Clark Steppler and Jim Wolf, EPROMs how I love thee. Went on from there applying a tune to anything I drove.

I like the 034 Motorsports approach, they leave some headroom to account for unpredictability on the street. They don't try and bend the will of the ECU to their desires, instead work with the factory inputs and features. They are mindful of possible issues with too much torque for the rods. Tuning is a multifaceted endeavor, results can be achieved in a few different ways, but physics is physics and VE changes depending on parts, for best results stick to parts the tuner knows or has created.

No problems so far, plenty of power, good part throttle control, good idle, good cold start. Has a tasteful application of exhaust crackle bling. The TCU shifts are great, it doesn't hunt, adds a little more gear holding in Sport, more predictable kick down in Sport, little more aggressive downshifting when slowing down in Sport. Drive mode feels like factory, nice and comfy, still eager to upshift for econ.

[carlosvjr92]

LOL

My thoughts exactly on that lol. They were great on the 2.0T back in the day apparently (was before I was into VW or Audi so I have no idea, only what I've been told), but seems they put no effort into development especially on the DAZA (even more so when compared to competition).
Seems most of their efforts are put into hardware that makes barely any noticeable differences, has any benefits, or solves any problems.

I've got their stage 2 tune because it was on my car when I bought it and so far has proven to be reliable and hasn't had any issues...that being said if I had bought a stock car instead of one that was already tuned probably would've gone Uni. Like I said though, no issues whatsoever on mine. Car runs great. Just slow when compared to other tunes with same exact mods. Their stage 2 E file is slower than some Uni stage 1 E cars even. Which "should" make it safer, but I feel as if the margin of safety is huge and leaves a lot of potential on the table for no reason imo.

Hey John! Thanks for the info and I appreciate your honesty. I will defiantly consider you guys and if I do decide to go with DS1, I'll shoot over an email!

Unitronic or DS1 are really the only 2 options I'd consider.

This is how I see it after going through the experience of getting my car to stage 2.

Unitronic is great. Fast(literally holds all the records) and reliable. The only issues with them is if you are swapping fuels between ethanol and 93, its a huge pain in the ass, requiring you to carry around a laptop, setting up phone as a hotspot, etc. Also, if you go catless downpipe, you will experience the dreaded wastegate rattle. Uni and some of their customers claim that their catted downpipe eliminates the rattle, other customers claim differently.

DS1 - not the fastest OTS tunes, but custom tuning is available and cost ~$500 that will get you speeds on par with Unitronic if you're looking to push it. True flex fuel, aka you add whatever fuel you want and just go, the tune will auto adjust by itself, no hassle. Complete elimination of wastegate rattle through tuning. Can change between aggressive, safe, cooldown, etc maps in a matter of 5 seconds while driving. Best datalogging software. Custom gauges displayed on the Virtual Cockpit.

Initially DS1 looks more expensive, but factor in the fact that you can buy a catless downpipe(assuming your state doesnt have inspections) instead of uni's $1700 one and that save you $1k right there. Also the flex kit for DS1 is ~250 whereas the P3 gauge setup(which is what I'd use) will set you back ~600 if running Uni.

[M3_Dylan]

LOL

With almost 25 years in the industry and a plethora of cars under their belt, it's always seemed APR was the "boujie" if you will; way of tuning. Especially with their warranty.

This is pretty much what I was thinking based of the general consensus in the community. In Ohio, E85 is here and there. Thankfully I live downtown in Columbus so it's around but still out of my way to get. True flex-fuel is a massive bonus however, if I went with Uni I would just run a 93 map as 93 is at just about every gas station up here. Also if I'm traveling, like you said: it would be a huge pain in the ass. I will note that just because you have X tune doesn't mean you need to have all of your bolt-ons be from the same manufacture. You could have APR downpipes with a IE turbo inlet running a UNI tune and I don't think it would make any difference. At least that's what I have read amongst both the RS3 and B8.5 S4 forums.

[jd_rs3]

Happy with my Eurocharged Canada tune. Fastest stock turbo in CO versus every other tune mentioned in this thread as far as I know. FWIW. Not opposed to any other tunes mentioned here though, just providing another option/experience.

DS1 can also do flex fuel on the stock injectors and includes options for stock, 850cc, 980cc injectors. If you change your injectors or go from stage 1 to stage 2 it is a 30 second flash from any device that has a modern browser, doesn't need an internet connection, a cable or a battery tender. It supports 91, 93, 100 and 104 octane with any blend of ethanol all without flashing. An illustration of its power is that it can even be custom tuned without flashing. As the ECU knows the ethanol content it cold starts well, transients are perfect and it can automatically modify the boost level if needed in cold conditions to suit the fuel system if you have stock injectors and full E85. Whilst you pointed out there are additional costs to pro-tuning, that is optional, and AFAIK the only one of the options listed that has the option to pro-tune at all.

[NRDORS3]

I personally would recommend DS1. As expensive as it is, the features are just fantastic. Being able to flash your car within 10 minutes or less from your phone, the process is super simple. When you finally decide to go down the e85 route, their flex fuel is perfect. There is never a worry about having to switch maps in order to run 91 or e85, you just fill. This is especially helpful at times when you aren't close to a e85 pump. Being able to add gauges within the virtual cockpit is also fantastic. And lastly its nice that many companies protune through their platform.

I would recommend staying away from APR. Buying their parts is okay, but their software is another story. Especially if you're wanting to make nice power out of your RS3, APR won't be providing that. Their OTS maps are super conservative. I always end up hearing people starting with APR and later on going with another company(in the end losing out on money). I have also heard awful things about their customer support, so don't bother asking them for any help or advice if you decide to use them.

IE has great parts and decent tuning products. I would say their OTS maps are probably right in between APR's and Unitronics. I don't think you could go wrong with them.

Unitronic is definitely the alpha dog, especially since they work closely with Iroz. The only downside I see with them is it's definitely an aggressive tune. If you plan to daily your RS3, keep in mind of this.

I also haven't heard much about 034s tunes but I would guess their very similar to IE's.

I haven't heard of GIAC. I would recommend doing some more research or wait to see if someone has a response about them before going with them.

Too add, I would also look at Eurocharged Canada. I have heard positive things from them, but not enough info to give you a definitive answer. jd_rs3 would be the guy to contact if your curious about them.

two questions for you (not a 2.5T owner yet)

1) I noticed your in the UK, what is the process for OTS for North America? Do you have a shop in US or Canada where you do your tuning out of? Always under the impressions there is a difference between NA and ROW cars
2) Since the 8Y RS3 is popping up in the UK now, any success in simply plugging in the device and ripping down the road? Or is there a new ECU and work to be done?

As far as I know DS1 supports all box codes for DAZA and DNWA including RSQ3.

I guessing 8Y is probably going to be Bosch MG1 ECU. Working their magic on the MG1 is probably next on the list.

We're a UK company, but we have people on both sides of the Atlantic so we do overnight shipping in the US for example and much of our development there. We developed DAZA in the US. We developed DNWA in collaboration with tuners in the Europe and Australia. We have worldwide support of all the vehicles we support.

New ECU, we're doing the 4.0T first.

Hey John, I appreciate all the information you provide and being so active and transparent. I plan on picking up a DS1 soon. Quick question for you concerning the DS1, though. Somebody made the comment to me “the DS1 has less than the oem system in some things”. I’m not convinced what they’re saying is the truth but hoping you can maybe elaborate if this sounds right? Thanks so much!

[ECNMY R]

Researched this myself this summer and came to the conclusion that DS1 is leaps and bounds beyond the competition from a technical standpoint and their OTS tunes are as fast as anyone. These guys are getting ridiculously fast and safe results on every platform they touch, from RS3s to 992 Turbos to 720S's (Google M-Engineering). People get caught up on the Canadian cable company being 1mph faster or whatever, but they pop motors and their spaghetti code takes 20 minutes to flash.

4k miles on my DS1 91 tune, it's fast and flawless. And the DS1 itself is one of the coolest pieces of tech I've bought in years. Huge recommend.

[brobst]

Going with 034 because they are local to me and tune for 91 octane. If I was building up, sure custom tuning would be ideal but at stg 2 91 its mostly who can give me the most support. No records to be had for me on 91oct.

What they have said is incoherent. Happy to discuss specifics if they are forthcoming, but this is just more misinformation from those without understanding or an inferior product usually.

[M3_Dylan]

Is a DQ500 tune necessary for S1? If I go with DS, I can always have a reputable tuner create a TCU file for me for probably the same cost as an OTS DQ500 tune. I'm planning on running a 4' turbo inlet with an aftermarket intake and then flashing over to Stage 1. Down the road, I'll pick up a downpipe, intercooler, maybe some other things, Stage 2.

[tegxsi]

Going with 034 because they are local to me and tune for 91 octane.

I had the same idea and I wasn't happy.
I won't really go into it. Stage 1 91 was ok and E85 tune didn't run right...

Can't comment on Stage2. I did sit in the white shop car and that was nice but that car has switched to DS1 since it got built + TTE.

[John@DEADBEEF_DynoSp]

M3_Dylan, we would not add TCU tuning as a requirement until you upgrade the turbo, but we add some logic to the ECU so that a torque limit from the stock TCU doesn't have to be disabled. We also implemented the same torque doubling strategy on CAN bus that is used in the 4.0T and 5.2 by default so that the TCU can see higher torque although that mostly has a role in custom tuning. You can see whether the clutches are slipping in our logs and we collect many samples through a gearchange to see the torque interventions, ignition/throttle response, RPM trajectory and longitudinal g whereas many loggers just show a single drop in RPM between one sample and the next. TCU tunes are loved by some and have a foibles and jerkiness for others.

[mtwallace85]

What they have said is incoherent. Happy to discuss specifics if they are forthcoming, but this is just more misinformation from those without understanding or an inferior product usually.

Agreed, and thanks again! Can’t wait to get my DS1.

very well said sir *insert clapping sticker*. I agree with you on how you broke down all the tuners! Uni is the better option bang for buck, if flex fuel is a must then you can go with ds1

very well said sir *insert clapping sticker*. I agree with you on how you broke down all the tuners! Uni is the better option bang for buck, if flex fuel is a must then you can go with ds1

Here is a breakdown of the costs for the various tunes as well

Unitronic- Stage 1/2, $900/1000 + $150 cable required for flashing
DS1- Stage1/2+Flexfuel Capability, included dongle- $1300
APR- Stage 1 $700 + $221 OBD2 -Dongle or go to local APR dealer for flashing (labor charges may apply)
034- Stage 1/2 $700/$900 + $150 cable required for flashing
IE- Stage 1/2, $700/800 + $150 cable required for flashing

I've been following Mitch since he was working for Cobb and will continue to support any products put out by the Dyno Spectrum team. Their development, customer support, and willingness to continue to improve their software to meet the needs of the end users has sold me. They have basically given end users standalone capability utilizing the stock ecu which most don't understand how big of a feat that is.

[brobst]

91 tune. I need the gas mileage and didn't want to do port injectors. Plus for stg2 e85 I would want a few more hardware bits.

I’m thinking I’ll start with 93 until I get the supporting parts installed. I’m blending 91 and 100 as it is anyway

That works. Just more work at the pump. Since I use 91 almost exclusively it made the most sense. Half the time I'm stuck in traffic anyway lol

Here is a breakdown of the costs for the various tunes as well

Unitronic- Stage 1/2, $900/1000 + $150 cable required for flashing
DS1- Stage1/2+Flexfuel Capability, included dongle+ protune $400= $1700
APR- Stage 1 $700 + $221 OBD2 -Dongle or go to local APR dealer for flashing (labor charges may apply)
034- Stage 1/2 $700/$900 + $150 cable required for flashing
IE- Stage 1/2, $700/800 + $150 cable required for flashing

I've been following Mitch since he was working for Cobb and will continue to support any products put out by the Dyno Spectrum team. Their development, customer support, and willingness to continue to improve their software to meet the needs of the end users has sold me. They have basically given end users standalone capability utilizing the stock ecu which most don't understand how big of a feat that is.

Don’t forget to add $400 to DS1 for protune to be at UNI level of performance. Most features need protune to be enabled like wastegate rattle delete.
