2005 GTO
I am currently running a 4L80e on my 4L60e tune with the relay to reverse shift solenoid B.
As a result their is no need for the Input speed sensor.
I would like to be able to measure converter slip via the ISS.
If I pin the ISS to the TCM with the 4L60e tune will I be able to log it?
If not has anyone been able to connect the ISS to the HP Tuners MPVI with a custom PID?
