    I forgot to mention that I did confirm the PRNDL switch is reading and the Trans Current Gear reflects the gear it's in. I even see the idle advance populate at a stop and then disappear once the car...

    Trying to perform a segment swap on a 99 C5. The car is a manual and needs to change to an automatic. One problem is that the manual tune is a 2-bar OS, so the OSID's aren't the same. I figured "no...
