I also ran slower than ever and in great weather managed a best of 12.3@115. I won't race again until I get my TCU returned to stock as it's not worth potentially blowing my engine..........and running slower at the track.
i have the latest tune from jerry. i have datalogged and theyare finally on the right track. the setup is now ecu 6500 rpm, tcu 6200 rpm and torque limiters set at 1000 newtons. this allows for easy smooth shifting in D no different than oem. in summer with manual selection the shifts are quick and firm with no afr spikes and zero lag. is it faster than oem? i cant say. i have had so many tcvu mods tried i forget what it was like oem. the only thing i found was that in w mode the tcu still shifts at redline doesnt hold the gear like i thought it should.
