While not in a truck, and not in 8L90, I have an 8L40 in my 4 banger Camaro. I notice the same, the 3-4 upshift almost always happens faster than commanded. I spent a few months tuning my trans, and...

BUMP... have you guys found anything new yet??? I'd really like to see some more tables available on the T87 as tuning is pretty limited.

downloaded 3.7 beta. I see there are more tables. nice...

I'm no transmission expert, but I've always heard there is two things that will kill a transmission. Heat, and Slipping.

When stock at WOT, in my logs I can see the trans was slipping between...

Yeah, probably can't get it to shift faster than .125, and even at that, I can only get my 3-4 shift to do that. The other gears are in the .150-.200 range, but I was still experimenting with raising...

Doubt the TCM being locked still is causing you a problem... Plenty of people on the Camaro forum have 2017s with locked TCM's and have only tuned the engine making decent power.

Did you change BOOST MAX LIMIT???

I guess I will contact support...

What I figured would happen did happen. Wanted to do just a trans calibration write, selected DO NOT WRITE for engine... After the flash the car would not...

Dang... I had a similar issue on my 16 Camaro... Lost power during a write eng/trans calibration, no big deal... Well i needed to do a read entire one day because I had made so many changes at the...

So my old laptop died, I think it had version 3.4 on it? 3.5? Wish I could remember, never had any problems with it. Always seem to have issues with 3.6.x for some reason on my work computer, so...

I would guess that either pattern A or pattern B is related to the tow haul mode? Not sure which, just a guess. Judging from the shift speeds, I would guess pattern A?

It looks like the TUTD...

If the option is available, in the software, have you checked to see if TUTD is enabled or disabled?

Sounds like a similar issue with 12-15 Camaro 2LS trim models, "sport mode" didn't allow full...

Disregard, wrong section. Delete if possible.

I see.

Changing the base shift pressure for tcc on or off does not seem to effect the TCC locking/slip... Pretty sure the tables we need are not there yet. Those Upshift pressure X/y/z tables you...

I would think that it would be always apply, but I'm not certain... If that's what you were trying to do, I would just set it to 1 myself... In your first row, it will never apply because that speed...

Did you ever get an answer to this? I sometimes have issues on my 16 Camaro, I attribute them to the car having the push button start that will switch itself back to the "off" position after a...

I'm using the throttle body from a 12-15 LFX v6 Camaro.

Thanks for your reply... In terms of increased support, I was more looking for tables that I'm used to seeing in the a6 tunes... A lot of them are missing, specifically in the TM section... Are they...

Having just really started down the tuning path with my 2016 Camaro, I realize that a lot of the tq management tables that I'm used to on older a6 cars are not present in the a8 car... I'm guessing...

If you are talking about the white "silencer" thing in the intake tube, the tube actually flows better with it in rather than taking it out. A new intake tube would be the way to go if you are...

I still haven't messed with the tune, just been logging things... I'm currently testing a 72mm throttle body (stock is ~59mm, but the intake manifold inlet is 67 mm)... It seems to like it, and I...

Gotcha. I'll keep an eye on it.

I just uploaded the stock tune into the repository, it is awaiting approval from HPT staff to become public

I just bought a 2.0t Camaro on Monday. I haven't tried tuning it yet, but did pull the stock file and have been doing some logging. I will try to upload the stock file tonight.

Max boost I have...

Any luck with this E93A issue? I have a 2013 Camaro, and it would be sweet if I could do something with it... I'd gladly send the desired files if I had the appropriate software/tools, but I don't...

Apparently you aren't reading what I'm writing! When the truck was BONE STOCK, NO TUNING, it ran completely normal... The more that was added the worse it began to run, which makes perfect sense...

I agree, tuning won't fix a mechanical problem. But if it ran perfectly fine before the tuning, wouldn't you think it wouldn't be a mechanical problem? It ran great completely stock, fine after the...
