I recently installed a 102mm Holley sniper efi intake manifold/sniper efi fuel rails/and a 102mm granatelli Motorsports throttle body on my 2008 Base, however once I started it up RPMS dragged and slowly started to increase by themselves. I understand tb relearn is a thing just haven’t been able to get a straight answer as to how I can do it. The car is constantly revving and if not stopped will continue to accelerate even with foot on brake it’s causing my shifts to be more forced and unnatural if anybody has any advice please get back to me. Thanks
I have the FAST 102mm TB on my LS2 and it was advertised as plug and play. It was. I drove it to the dyno shop. However, I still tuned the engine. Granatelli says you need to tune your TB.
Without a bidirectional scan tool you can still do this “idle learn”…
1) Idle the engine for 3 minutes and as the ECM “learns” these new idle cells the RPM should start to slowly decrease.
2) Turn the ignition off for 60 seconds.
3) start and idle the engine for 3 minutes and verify you have the correct idle…BTW, this is the method from Service Information so it’s the right answer !!
