Default Dual tuning a possibility
Is it possible to have (2) different tunes on one PCM and have a switch to alternate between the two. If so how would I go about doing this.

EFILive has a Custom OS that works like that. Basically, you have your normal tune, then at the flip of a switch, you have a tune with say more fuel and less timing for nitrous.

How would you set up a switch for the PCM for that kind of scenario?

It grounds red pin 56 on the PCM, which activates certain fuel and spark modifier tables that are built into the EFI Live custom OS

You will have to have COS5, and those tables will have to be activated and set up, so most likely that wasnt done before and you will need to have it set up in your tune
