I've got a 2015 Corvette Stingray A8. I've attached the tune and a datalog. The RPM limit is set to 7200 rpm and I've got the shifts programmed to happen at 6700. There is some sort of rev limiter I'm hitting at 6600. I'm at a total loss here. I'm relatively new to the A8's and have no idea what is causing this. Any help or insight would be greatly appreciated.

hello what have you done to you car? im asking you coz im traying to tune my corvette c7 2015 but i have not idea how to use this hp tuner lol so i was wondering if i could use the tune you have made i have intake and headers thanks
I've got long tube headers, AFE Intake, X pipe, E85 and tune. You can use it, just go into the tune and TURN OFF the Flex Fuel sensor.
Had a similar issue on my camaro, ended up being the oil temperature rev limit table, pretty sure it was next to the other limiter tables. I can't look at it right now since I'm at work.
I've got it set to 7200 rpm as well.
YOU HAVE TO Equal all of your WOT SHIFTING RPMs to 6700 and it'll work , the pcm was confused with jumping from 6700 to 6600

Under ( Fuel Cutoff RPM vs. ERT vs. ECT) return it to stock values that would be 6600rpms I believe then add (600rpms) to all over the table by using (+) to equal your RPM Limit Extreme Cutof that you make it 7200rpms
[ECM] 12063 try to make all this table to 7200 and try
Try making your part throttle Speed shift tables match the full throttle tables mph. When I am adjusting shift points at the track, I change the Normal, Pattern A, and Pattern B Upshift mph on Part throttle and Full throttle.
On the part throttle tables only change the mph for 87% throttle and up(last three columns)
Edit: BTW.. your wot 1-2 shift at 38mph is a little high. Will have to drop that. Be aware and don't hit the limiter or overrev until adjusted out to shift correct

Also another hint. If you don't want the car to feel as lazy in 1st gear, go and change table [ECM] 33014 to 100% all the way across. Stock tune doesn't let the car go full throttle until 3200rpm. Be ready for tirespin
i got the e85 sensor and installed it and i copied you tune but im geting this codes now P0171 and P0174 and i feel like the car is not working propely any help
You have to go through and recalibrate your MAF sensor. Your's is obviously not the same as mine. No 2 cars are the same.
Under speedo change source to Calibration and change the Speed Limiter to something like 255 do not max 318 also go under Engine Diag and raise Min ECT to 265 and Enable RPM,
had no experience with gen 5 stuff but when your limiter is active are you by change in TUTD position with the selector?
I cant make sense of the PRNDL status :unknown 82
but if its In TUTD the full throttle shift rpm is 6700 and the data log shows 6671RPM peak. the torque reduction for upshift in TUTD is enabled.
the way timing cuts, TPS starts to fall and the injector pulse width falls off with the MAF hZ falling away also..... that looks to me like its staged torque reduction for upshift.... its reached its 6700rpm limit but miles from the 161mph speed for 3-4 upshift in TUTD.
What are you referring to in raise Min ECT to 265 and Enable RPM. What cells are you talking about?Originally Posted by C5 2000
The 1/2 shift is the ONLY shift that I actually hit. 2/3 and 3/4 always hang up.
