Tuning options for 2019 S5

[CarsandChicken]

Hey Guys,

New member here, just picked up a 2019 S5 Sportback in Navarra Blue with Black Optic Package and S Sport Package on Monday. I'm looking for tuning options right now and wanted to see if anyone here has experience with any of them. So far it looks like my options are APR, Weistec or a JB4. I'm leaning towards APR Plus, but wanted to see what everyone's opinions are.

The APR tune for the B9 is not out yet. I am impatiently waiting to see it.

[CarsandChicken]

Damn, I didn't even realize that. When I went to their site I saw it as an option, but it redirected to the S4 every time. I assumed it was a glitch.

[Paintedblack]

The tunes for the s4 and s5 should be pretty much the same... APR is still working on the s4 tune.

You may want to check out the JB4. I am running the JB4 on my RS5 and love it! I have had true flashes and piggybacks in the past, and definitely a true flash will be better but have to say they have done a fantastic job with the JB4 on the B9 platform. Im running 5 gallons of E85 and the rest 91 octane and my car is ripping. Plus the fact of not having a flashed ECU is kind of nice as well. Im sure you already now all of that but I am more than impressed with the JB4 so far.

This is what turns me off about the JB4 on this platform. It seems like everybody who is really happy with it is monkeying with fuel mixtures or running WMI. I haven't seen any feedback of meaningful gains on normal CA 91 octane.

I had a JB4 on my Golf R and a similar piggyback box on a Cooper JCW and those were a night and day difference on pump gas. I'm not sure why the B9 cars don't get that result.

It looks like there are a few JB4 units in the classifieds, but like zed said I'm not looking to start mixing fuels. The JB4 is definitely much cheaper than the Weistec, which is a little concerning.

The price differential is a non issue, the JB4 is solid. I’m running a JB4 on 93 pump gas and there is a noticeable difference from stock.

I too have no interest in mixing fuels, but the tweaker in me is tempted...it’s one of the appeals of the JB4. If I were you, given what appears to be the imminent release of APR’s tune, I would just wait a little while and go with that option.

[CarsandChicken]

Has anyone had service work done after installing a JB4? I know the unit can be removed easily, but I was told that Audi can still easily detect that the ECU was modified for a number of reasons.

I had warranty work done with shit installed and they did not give a crap. Warranty work was like 2k to trani, I am fully bolted with JB4, plus I have 034 full set under car.

I've been running JB4 for about 4months or more.
I'm on map4 and with supporting mods with good 93 fuel, it is noticeably faster.
I have Injen CAI, APR FMIC. no exhaust mods.

[CarsandChicken]

Still waiting to see what APR releases for the B9, but I am very hesitant to get anymore software from them.
1. Their stage 1 tune blew the motor on my 2016 A3 a year or two ago
2. APR now offers APR Plus, which essentially means they are aware that their tunes blow motors and will cover it if you get APR Plus.
3. Still a little pissed that their stage 1 tune blew a 2.0 so easily. I had the tune in the car for a year before it blew, so it was well broken in.

To date on any of our VAG Group cars which include Audi, VW, Porsche, SEAT and Skoda we havent had any cases of detection even on very large claims and ECU's being sent to Germany. Only way you will possibly have a issue is if they flag the car for modifications that are visible.
On 93 you will be plenty happy with it. Majority of enthusiasts post so those are the guys that are typically using mixes but the largest portion of customers dont blend.

What can a California guy with 91 do with a JB4 who doesn't have plans to mix either?

I've always ran APR tunes on my past 4 Audi's. Currently Stage III KO4 on my wife's B8 A4, no issues 30K+ miles. That being said trading it in for a 2020 S5 and adding APR Tune once available. Trust me, APR knows what they are doing and work closely with VW/Audi to keep within limits.

I just saw this part now. As a company we charge realistic figures that are not based on value of the car. Whatever it costs us in development and ownership of the test car we feed in to a formula that dictates the price. The units are made in the US local to us and we make a decent enough margin on them and would do far more volumes than a flash tuner would do as we are in nearly every market worldwide and the DIY aspect and Brand awareness in this field allows for large volume. In many cases the same circuit board can be used on other models and on this one specifically it is shared across a decent enough platform so the return on development is spread.

S5 tune: https://www.weistec.com/e839-ecu-tune.html

RS5 tune: https://www.weistec.com/ea839-tt-ecu-tune.html

I wouldn't trust their information. Their data is all over the place and here is my detailed explanation:

AUDI uses a generic 354hp(or 349hp)/369 lb-tq for the S5 and 444hp/443lb-tq for the RS5. Most of us know both cars actually put more power but that is not my point right now. if you guys take a look at both links you will see that they left the stock power on the S5 as 349hp/369lb-tq however they are saying that the stock power on the RS5 is 490hp/"566". Is 566 Newton meters or Lb-tq? lets assume is lb-tq, now they are claiming the RS5 puts 123lb-tq more than advertised from Audi? that seems a lot.

Lets move to the other part which I find also strange. They say that the S5 gains from a tune 66hp and 111lb-tq (I actually believe it) but when you add up the numbers now you have 420hp/480 lb-tq according to them but if you add the numbers it should be 415 hp/480lb-tq.

If you move into the RS5 numbers now they claim gains of 35hp/64lb-tq so it should be 525 hp/ 630 lb-tq. Their numbers are all wrong and there is a reason why. They did their math wrong, they are adding numbers to measured stock hp/lb-tq on one car and not the other. They are also using the stock measured power/torque on the S5 directly from Audi but they are claiming 490hp/566 stock on the RS5.



It is just all wrong. I am not bashing the tunes, I am just saying the numbers don't add up.

I had a JB4 on my Golf R and a similar piggyback box on a Cooper JCW and those were a night and day difference on pump gas. I'm not sure why the B9 cars don't get that result.

When you say meaningful gains, is this from actual owners or based on the forums? Asking because I haven't been able to find feedback on just using 91 octane either. I'm hoping it's at least the 40-50hp that other platforms are seeing?

[edleeid]

I just installed JB4 on my S5 few days ago, and It was noticeable gain and more fun to drive. I live in LA with 91 octane only as well and have no desire to mix any. Mine is set at Map 2 and I think I can enjoy as it is without mixing ethanol for extra power.

George from Burger said we can expect 50hp and 55 tq gain from Map2.

Unless EPL(had it on my B8.5 S4 and loved it) comes out with tunes I can install/uninstall from home, JB4 seems like the perfect solution for my need until warranty expires.

Glad you love it! I'm hoping to get the same kind of feedback on the RS5.

I thought were limited to Map 1 with 91 this entire time. Do you know if we can safely use Map 3-4 as well on 91?

[Paintedblack]

I haven't seen too much on 91 octane. I did see some numbers about a year ago and i also mentioned my draggy times in a thread or two.

On 91 octane and completely stock plus a Racechip piggy i got:

1/4 mile: 12.14 sec
0-60 mph: 3.8 sec

That is the fastest for 91 octane I have seen, but it haven't seen any numbers in many months. At the time I saw some DTE/DTUK and JB4 numbers that were slightly lower than mine. I'll add my times to the 1/4 mile thread when i get a chance to upload the screenshot so we have a 91 octane reference.

[edleeid]

From what I've read, Map 3 is not recommended for S5/S4 with 91 octane unless you have some added on aftermarket parts (intake, intercooler, etc.) The log can be saved from the App and sent to George for a review whether it is safe or not. For Map4, you need to mix.

this morning was first drive to work with JB4 on, and it was really different. My commute ride is very hilly and pulled much harder, while still feeling smooth as stock. Map 2 seems good enough for me, at least so far. :)

I've been asking for any timeslips or dyno data for a car running JB4 on 91 octane with no other mods, and I still haven't seen any. I ran a JB4 on my Golf R and was happy with it, but there was a ton of data on that platform that doesn't seem to exist for the B9s.

Good to know. Thanks!

I tried messaging George but no response yet regarding the various Maps and 91.

So mine were not with a JB4, but its is with just a piggy on 91 and no other mods. I would expect a JB4 to be able to match it or do better...

This is not our release thread, but more just informational with a lot of good questions and answers.
