Following Vancity Audi beating on his RS3 with less to no problems compared to this! Wtf is going on?? Anyone?
Anyway, fun to see when it worked and that the 911 is stock running 10.2!!

Looked like it was running out of fuel.

[elijahallen]

Its common on Stage 3 Uni tune, it won't shift on its own from 3rd gear on. They are supposedly coming up with different tunes for different tire sizes so hopefully that will fix it. The other time it happened toward the end of this video was fuel level was to low, that's a common problem in these cars after being tuned, I had it happen once and keep the tank above 1/4 from now on to avoid it.

BMW sounds like absolute fucking garbage. You couldn't pay me to drive that junk.

Rs3 wrap/paintjob looks like poo. I threw up in my mouth.

And what's with these HP numbers? Are these wheel HP numbers? Corrected HP? If so, what was the correction factor? Crank HP? I hate seeing HP #'s online. Means nothing to anyone without proper context.

Thought I was alone with this shifting issue lol. Curious if its tune related or tcu related or both. Would love to know more about what causes the need to manual shift instead of having the computer not shift on its own.

It has to do with tire and wheel size. They are going to come out with specific tunes for different diameter setups. Hopefully soon.

How odd. My tire size hasn't changed from stage 2. So your saying they designed the TCU / ECU tune for different than standard height tires? Regardless it seems strange, though hasn't this been said for some time now?

[WmRS3]

My stage 3 Uni tune on my 20 shifts fine. The shifts are firm but she shifts in auto mode no problem.

Nice, have you done drag racing (sport w/ launch control) and let it shift by itself passed 3rd or are you referring to just driving since that aspect is fine

Yea its only stage 3 that has this issue. Strange indeed, it doesn't seem like it would be that hard.

[Jeff_Jeske]

My one take away from that video was that you can fuel starve the car and it protects itself fairly well! Staying in the gas like that while running on fumes would cause catastrophic damage for most cars.

I have to admit I've done it myself at stage 2 .... hard right handers cause fuel to slosh away from the pick up and the end result is the same. I know people are working on a solution for this as we speak.

Either way I now only race with a full tank of fuel. I don't care about the extra 35lbs as I don't want to experience that ever again.

Drag racing and street driving two sets of wheels and tires fine on both. Car was slower when I shifted it.

I’m on built block motor file maybe that’s the difference since you can go higher in rpm unlike stock motor.

I have issues!! Lol. I just know to avoid what happened in this video. I always race in Manual mode because (as I've stated in my videos) the Uni TCU tune isn't 100% sorted. The crazy amount of break up you heard was most likely fuel starvation like so many others have already mentioned. I never race with less than half a tank which has always prevented this for me. It's truly a shame they race in the UK because I would pay money to line up against them in my RS3 and see how I do.

[TheContrarian]

I think the moral of the story is Porsche is the undisputed king. All the work & money thrown into the BMW and Audi just to run comparable times to a stock Porsche with a warranty.

Haha. Ok. Your videos seems so flawless lol
So I guess there is a reason why the uni stage 3 TTE700 is still marked as a beta tune.

Yeah and just wonder if you start tuning that beast just a tiny bit :)

its 4x the cost of an RS3 and 2x the cost of the M5. I would hope it's a fast car.

Porsche is the king of all kings.

That’s why I own a 991 GT3.

^^^This. But yeah, the Porsche 911 really has it all, IMO.

I keep thinking about a 991.2 C4S as a Turbo "lite" with the right mods...might be attainable some day. Though recently all Porsches seem to do is appreciate in value!

What rpm? I’m on my stock block and 7800rpm redline I believe 💪🏻🇩🇪

That RS3 tune and TCU is trash

I don't understand why the TCU would not shift 5/6/7 automatically? It knows RPM, gear, and I'm sure it has an internal concept of "wheelspin" or loss of traction.

Those things combined with some hysteresis thresholding should be enough to make a decision regardless of wheel/tire combo or no?

[WmRS3]

Super weird some do and don’t mine is fine on stage 3 ecu and tcu so far. Shifts are just firm my car is a 2020.

[elijahallen]

Here is a video of my car hitting the limiter in a roll race video. Unfortunately it happens when I am ahead for a bit but if you turn volume up you can hear me hit limiter then lift and floor it and hit limiter again and then manual shift. This was in dynamic mode in auto not in manual mode. Its quite annoying to say the least but Uni is supposedly coming up with revised tunes to fix the problem. My wheel/tire setup is 19x9.5 with 265-30-19 PS4's

Watched your video when searching YouTube before your stock block? Mine would do the same if I left it to shift on its own (kind of disliking manual shifting at that high of speeds at this point), would love to just leave it in auto/sport and let it do its thing. If i were to guess it has something to do with increasing RPM of motor and the TCU not working correctly at that high of rpm shifting. From what little we can get answers on this its been said tires, if that is the cause what should we change them to? Is that the issue or is its something else. Assuming Adam (vancity) might be able to help get a better answer to this subject than me guessing. Would love to know the solution to have it auto shift on its own, sure would be more consistent especially for a drag racer.

Yea its stock block for now, I have a built motor being shipped soon to be safe. They have a tune coming for a 25.3" tire and a 26" tire so we can choose what's closest to our setup.

[brad65ford]

right on, if I were to do it over again I would have slapped on a TTE700 and run pump gas its that quick. Currently running 93 file on build block and I'm impressed.

[RudyH]

Porsches aren't built for the drag strip lol, that 4x the cost and 2x is found in the corners...

***edit
to put it better, the Porsche is engineered for what it does, to include a level of reliability. Most enthusiasts build a car based off what they learned, with a fraction of that budget, and as we learn things don't quite work out right...but hence why we love the challenge. This race highlights that quite nicely.

[jd_rs3]

wait, are we actually comparing RS3s to 911s? LOL

You take the Porsche to over double its factory rating and see what gremlins pop up. No car is immune to the trials of modding.
