19's rev rpm max change

[brad65ford]

Yes, I know this is silly to ask but here goes. As we know the 2019 and newer rs3's will not let you rev passed 3,500 rpm and wondering if that can be changed? After running the TCU tune and having the ability to changed different RPM ranges on launch all would be well and good but not for us 19 owners. Even though I flash the TCU launch to 3,800 or 4,000 rpm, max will only still be 3,500 RPM. So assuming even a ECU tune isn't changing this setting. Is there somewhere in the VGA settings that can change this?

Oh and yes, I like to rev my car pasted 3,500 rpm since it sounds good.

What TCU tune are you running?

[signde]

ECU tunes do alter the rev limiter.

Furthermore, we’ve added left foot braking, removed the speed limiter, raised the rev-limiter and added a motorsport limiter, reenabled the exhaust crackle on modelse where it was removed (2019+), adjusted the factory exhaust crackle to protect the catalyst on Stage 1 and 1+ and enabled in more scenarios on Stage 2, optimized cold start, retuned the exhaust flap actuation for the best performance and sound in multiple modes, optimized high altitude mappings, retuned the throttle for better response, and completely optimized the driving experience for street and track use making for a much more enjoyable driving experience!

Because in this day and age despite how easy it is to communicate... People still can't communicate.

I believe the OP means, while the car is stationary. That's the only thing that makes any sense.

Yes, correct. Thought that would be obvious. My apologize for not explaining in better detail.

Also I'm incorrect its 3k max which is just down right sad.

i understood that. i believed that is what the APR quoted feature implies as well, though in re-reading it, it probably it means the increased 7300 rpm redline.

my understanding is the stock neutral rev limiter is 3k, even in the previous year model 2018, as noted here and here. there are several other mentions of the hard 3k limit going back to 2018.

i thought it was the ECU tune that raised it beyond that, but now i am doubting myself.

Thank you, your right I should have worded it differently. Moving forward I was under the impression it was 4k on 17's but I could be wrong. Shame it can't be raised just because one would want it that way.

[signde]

this is the comment that lead me to believe the ECU tune increased the neutral limit.

https://www.audizine.com/forum/showt...1#post13830827

i want to go validate for myself but man my neighbors would hate me right now.

OP, are you ECU tuned?

[brad65ford]

Believe I was following that thread as well. Don't see anything positive about increasing the rev amount in neutral unless I'm not reading it correctly.

the exact comment i linked to:

I like how you can tell the difference on the higher rev limit as well - the 3k limit on the 2019s bugged the crud out of me.

his rs3 is also APR plus tuned, so i'm assuming he observed higher neutral rev limiting after tuning.

again, is your ECU tuned? if so, which tune?

[Brian@Unitronic]

The ecu and tcu must match to raise the launch rpm

all Unitronic ecu files are 3500 for stock turbo except the drag racing maps which have a 3800 rpm limiter (must flash the corresponding 3800 rpm tcu file)

This applies to 17's, 18's, and 19's

Brian

[brad65ford]

so thats why i can only achieve 3500 rpm lol

I think he is asking about the car stopped in Park. What is needed to rev the car in park or neutral while its not moving to like 6000 or so.

[signde]

was able to test this morning, i'm able to free rev well over 4k while in park.

[Velicos]

My APR Plus tune as others mentioned raises from 3k to 4k but can't free rev to redline. Also brought back crackles on revs.

EDIT: I feel I need to test again now, as others have said with their APR Plus tunes they can free rev as high as they want..

[signde]

actually looks like mine tops out just a little beyond 4k

[omniphil]

Is there some technical reason why the car can't free rev to redline? Why would Audi set it this way and why do the tuner follow suit?

[allerum]

Are there any tunes that let you Rev it out to 6000+ in park?

Just to listen to it? Just like most exotic owners in every parking lot. To be obnoxiously childish? Lots of reasons. Its fun sometimes.

I agree. Isn't that how we got jsnmr2's glorious bullx rev clip? (correct me if I'm wrong, but don't those middle revs go way high?) Pretty sure he was running custom code at that time before they sunk and if I remember correctly, their tunes allowed high park/neutral revs. I actually think it's kind of important on these cars to shock people thinking it's an a3. I have been in social situations where people I know built up expectations to people not in the loop on these cars who then wanted a rev demo - and though it still sounds good, a full range would be much more impressive. It might be dumb, but it would be a very nice option.

I appreciate the insight

As a performance software company , sometimes it's easy to look past the non performance modifications.

I'll pass this information to our calibration team.

So when little kids ask you to rev your car, you don’t look like the dickhead who basically says no. But seriously, I paid 60K plus, let me rev my car however the fuck I want, Audi. Especially with HOW good our engines sound. Idek why it would be limited? I mean we bought the RS3 trim....not an A3.

Nothing towards you or Uni, Brian!

Same as the others mentioned. Seems silly but once in a while to hear your car differently by having this ability

[SlowSedans]

In Brian's defense, I'm not sure everyone was on the same page in this thread about what was even being discussed.

The whole free rev thing is obviously polarizing, I assume Brian is viewing it as in general use. Like why would you obnoxiously rev your car for no reason.

My take, as a mechanic at as base level, sometimes you want to rev your car, hear your car, clear out your car, measure data at set rpm, static and no load, etc...

Why arbitrarily limit it? Why keep it limited on an aftermarket and enthusiast / tuner focused calibration. Different strokes is all I guess.

[brad65ford]

Just making mentioned of these since it would be a nice feature. Nothing more nothing less, not trying to start creating waves with any tuners etc....

If you update the calibration to permit free reving, would we get a notification about an update?

[SlowSedans]

Good thing my educational post was deleted. Some things never change. Good job advertisers! Really makes you guys look legit to squash info and hide things from the public about tuning.

I would imagine if we updated the file for something like the rev limit in park, we would also try to implement other changes at the same time and make an announcement

We also have a dedicated group chat where we keep customers up to date on software changes and look for feedback.

Brian

[a4 4snow]

It's one of those if you have to ask you don't get it type of thing lol... that said this is not the first performance car I have had that limits revs my M3 competition had some weird logic that prevented free revving however if you played with the right buttons you could get it to rev and pop. Gone are the good old days of no nannies on the car preventing fun.

[VirtuousWolf]

Hi Brian, any update on this? I am looking for a tune that can free rev to redline while in park/neutral. I know the 034 TCU tune allows this. I’m interested in getting Unitronic though, because you all offer stage 2 TCU. Thank you

The unitronic tune can free rev now in park and neutral. It was implemented.

[VirtuousWolf]

Omg!!!! Thank you b7! You just sold me on the tune! Their website should really update that!

[RaudiRS3]

How long ago was this update implemented ?

Also does anyone know the chat group or unitronic customers I think someone mentioned a WhatsApp ?

I don't know when I flashed my unitronic stg 1 a few months back it worked. TBH I think there's some confusion, some people including Brian were talking about Launch Control at some points. My understanding from reading before I bought one was free rev above 3k has been a feature of the major RS3 tunes for a while now. I could be wrong

[RaudiRS3]

Interesting, I cannot rev (park or neutral) past 3/4k . Just tuned within the past 1-2 months, currently on e85 stg-2..

Hmmm..

When you say above 3k, do you mean above 4K too? Mine does 4K currently stock, but can you do 7 for example once warmed up?

I have Unitronics Stage 2 ecu and tcu. I can rev freely.

They fixed it after myself and others posted about it and the map name to edit. Maybe they didn't get to all the versions. Good to see uni take on some customer requests for code changes.

[Jon B.]

Certainly makes an appealing case for prospective buyers.
