First attempt failed. (I believe the ignition powered down) Install original backup. Had to update tool again.
I installed the Diablo tune, then modified it as desired. Car started. No check engine light.
I scanned all systems and found a U0100 in Chassis control module. (I have a manual 7 speed)
Do you advise my taking any further action for this code? When selecting vehicle I did change the trans type to manual.
(That was several days ago)
I will try it as it is. I wonder if this will affect my skip shift warning!
I love working on cars!
Thanks for your help!
Tom.
