Working on a 2012 Camaro SS with a big cam and big converter. I cannot for the life of me figure out how to make this thing shift at WOT. driveability is nice, although fueling isn't finished...we're running MAF only for now until i can get the car back for a day or two. I've only done one other 6L80 with a converter and it was a bone stock car with a 2600 or 2800 Edge, piece of cake.
This car has a Revmax 3800 in it. The car acts like the converter is just too loose. i'm having the owner verify fluid level tomorrow as well, the car had a trans fluid leak for a day and i'm not confident the converter didn't get put in dry.
We thought me made some progress though with another attempt today where i set the shifts to happen pretty rapidly, that file and a log are attached. The root problem i'm fighting is that once you go WOT, the RPM's sail up to the fuel cutoff and the car stutters between gears before continuing on. It hits the fuel cutoff at or just after each shift. I want shifts to happen around 6000 rpm like commanded but the engine just revs so fast & the converter is so loose it misses the shift and hits the fuel cutoff....hence why i tried making the shifts happen in rapid succession but once it finally makes it to 4th, it bogs hard, which i now think may be related to the TCC apply in 4th. I didn't get a chance to experiment further since his woman was needing to go to Walmart before going in to work.....The attached file is the one currently in the car and the log is from that run. The previous WOT shift speed settings i tried were as follows:
1-2 @ 21mph
2-3 @ 51mph
3-4 @ 80mph
also tried like this:
1-2 @ 32mph
2-3 @ 37mph
3-4 @ 44mph
I've also had the shift rpm in 100rpm increments from 5800 to 6250. No matter what happens, i can get the 1-2 shift to happen as commanded but the rpm continues on up to 6500 in 2nd and the fuel cuts in each gear after. It acts like the shifts need to happen very rapidly but the car bogs in 4th. I know my current settings aren't correct and may not be close to what the final result ends up being, its just where i'm at right now and i'm out of ideas. Any suggestions would be greatly appreciated.
Thanks guys.
