Hello from finland. Forgive me for my bad English..
I have 2010 camaro ss. My car engine upgrade is: btr vtt cam stage 2 , bbk 1 3/4 longtube with cats, heartthrob exhaust(2,5 inch), kn cold air intake and Chevrolet Performance 88958758 heads. Dynotuned in finland, 432 whp. Stock converter, and stock gear.
Last weekend i tested first time in strip. Best is 12.9s/174 km/h.
Transmission is strange. This is a big slowdown!
1 and 2 gear is fine. When the transmission shifts to third gear, it comes on like a limiter. It switch back to second gear and then the switch to third gear succeeds. I tried 6 times and the same every time. Also in Burn out. There will be a "limiter" third gear. This at full throttle. In daily driving everything works just fine.
The transmission tune is a ready-made tune from this forum. He was looking for some ready-made tune for 6l80 tranny. Witching time approx. 25% faster, and transmission oil pressures approx. 25% higher. The torque limiters have been removed but someone is wrong transmission tune. I think.
Thanks!
The situation is pretty much the same as traction control / some limiter would go on. Both.( In Burn out and in full throttle acceleration. And only 2-3 gear.) Of course, I have switched off traction control and stability control. Today I am trying to test without those fuses..
Unfortunately i don't have a log. it must be taken. I tested this morning on the street. if i have about 95% full throttle everything works fine. Also 2-3 gears shift work great. I also tried removing the fuses 40 and 43. The only change was burn out would not work at all. The engine does not take rpm if I press the brake pedal. I put the fuses back. Traction control of and burn out is ok. In the first two gears.
Thank you all. I need change the tune and test in the coming days. If I remember right, the transmission tune is not camaro. I guess there is an s10 pick up with the same engine, transmission upgrade.
