    8l90 2nd gear launch tune

    How can we setup the 8l90 in a C7 Z so it launches in 2nd gear only at the track? I typically can do it manually but if I push the shifter to fast it will go right into N and that kills it.

    Thanks in advance!

    assuming you know how to set up the transmission to auto up shift in manual mode, you would just set up the tutd tables for a second gear start. then everytime you used manual mode you would have the second gear start, and if setup correctly you could leave it in manual mode , and it would auto upshift and the only thing you would have to do is down shift using the paddles.
