This is a big deal. And from what I’m seeing on the HP Tuners forum, it doesn’t sound like HP Tuners is even putting any resources into the 2020+ TCMs in terms of trying to crack it.

If you switch to a larger camshaft which normally shifts the power curve to the right, Ideally you want to bump up the shift points to utilize the increased power range and maximize the cams potential. Also depending on camshaft selection, it may require a higher stall converter. Different power adders benefit from higher stall converters such as F1a94 prochargers which seems to be a popular option on this platform. All scenarios I have pointed out here would require transmission tuning to maximize their potential. Does that mean you have to...NO. I am sure there are packages designed to work around the parameters of the stock transmission tuning but it doesn't really have anything to do with a power number alone. There is more to going fast then a power number.

Contrary to my post count here on this forum, I'm not a noob on how engines and cars work. I get that the trans tuning is a limitation but its not going to affect the majority of people. Sure there are some that will push the envelope chasing max power numbers and running large cams, but that's not for most. My point was that, while it is a limitation, I freely admitted that in my first response, its a non-issue for most.

As you stated, there's plenty of ways around a high revving cam, most swap cams in these cars for the fuel lobe and there's no need to rev the Hell out of the engine when more power can be had with more boost. I agree that there could be SOME ET left on the table with a properly tuned trans, but its not going to be much.

I'd argue that these cars not having port injection is a FAR bigger limitation than the trans tuning.

I never said you were a NOOB. Your post count could be 10k and I would of replied the same way based on your response to me.

Again, All I said was the 2020+ A10 can not be tuned. I never implied anything other then stating that as a difference from a 2017-2019. Then you evidently caught feelings about it since you own a 2021 and brought up Vengeance racing said "stock trans tuning is fine to 1000hp". Fine and optimal are 2 different things. I agree that most buying these cars do a few simple mods and call it good. So yeah not a big deal, but for others that want to mod heavily it's an important detail to know which is why I mentioned it.

Fyi, There is a solid 2-3 tenth reduction in 1/4mi ET alone from trans tuning even on a stock car.

Yep I have read the same.

Pretty minor detail IMO, but the infotainment is updated on the 19’s & up.

Off topic, but it's fascinating how defensive people can get about their choices, and that probably applies to me as well with my A8, even though I do freely admit and admire the superiority of the A10.

If I could start life over again, I'd probably consider a minor or even a major in psychology

I caught no feelings, you're just a prickly know it all.

I'm certainly not defensive, I made a statement from a top shop. Take it for what it is, some people feel like they know more than the top shops, that will never change.

True that...and yes I agree the ZL1 is a superior car. Far as the A10 being superior, that all depends on the application. Stock vs Stock hands down A10. At the drag strip, Tuned A8 has the advantage. Road course and everyday driving, A10 again. So yes I would say the A10 is better all around for sure.

And to be clear just because the 2020+ A10 can not be tuned doesn't mean I wouldn't buy one. There is a guy on FB that posted times of his 2020 A10 ZL1 going 9.8 @ 139 Full bolt-on with stock trans tune. Then says right at the end of his post. "Stock trans tune is holding it back".

Pray Performance also had a comment on this. I'll post some screen shots below.


Either way it's pretty much like this.

The 2020+ A10 can not be tuned = Fact's from HPtuners

X shop said A10 trans doesn't need tuning until 1000hp = Speculation provided by a C6 member that has provided no data or credible info to back that claim up.

A lot of useful info as always, thanks King. I'm actually very pleased with Ted's transmission tune for my A8, it does exactly what I want 99% of the time. The only thing I don't like is the slower paddle response time, and I've resigned to that not being fixable.

But that's where I'll stop before OP comes back and cracks the whip at us for steering his thread awry.

No Homelink starts in 2020, if I recall correctly.

I don't think you can get the optional dealer ELSD-reflash for anything after 2019 either. At least that's the last I've seen. I don't know if it matters much...

What are the advantages of the 2019 and up infotainment compared to 2018 version?

Higher screen resolution (1080p vs 720p), smoother transitions and more responsiveness due to faster hardware, wireless AA and CarPlay support (2021 only), improved navigation rendering.

The infotainment theme was redesigned, too for the 3.0 version in 2019, which I don't care for much, but it is definitely different.

[LT4Greg]

I would say the biggest difference between the two would be cost since you can’t buy a new 2018 now!��

So im wondering Something I have a 20 ZL1 that was manufactured in Aug 2019 it that mean my TCM can't be unlocked snice its a 20?
