tawss04 Posted June 29, 2006 Report Share Posted June 29, 2006 I am running nitrous on my truck, Brian at PCMforless tuned it for the nitrous. I know it would run better on a custom tune w/o nos than it does now due to the timing for the nos. I have a friend who has a 2000ish Mustang with alot of work incl F/I, he has a switch in the glove box were he can change the tune if he is going to run race fuel or pump gas. My question is there a way to do that with our pcm's, I would like to run a tune for nos and one without just by hitting a switch. I'm sure it can be done, it should not be much different than the tow/hual mode switch from the factory, it would be sweet to be able to use that switch being that i dont use it for towing Quote Link to comment Share on other sites More sharing options...

.justin. Posted June 29, 2006 Report Share Posted June 29, 2006 With EFI Live's Custom OS #5, you can. You just have to wire in a switch to one of the PCM pins and tune for it. Quote Link to comment Share on other sites More sharing options...
thomp62301 Posted June 29, 2006 Report Share Posted June 29, 2006 I have a timing tuner on mine that runs advanced timing while just cruising, then it retards it when the nitrous is activated. Works great. Quote Link to comment Share on other sites More sharing options...
BenKey Posted June 29, 2006 Report Share Posted June 29, 2006 I would just get a EFI timing box that retards for running N2O and back to normal for other driving. Quote Link to comment Share on other sites More sharing options...

allballz57 Posted July 3, 2006 Report Share Posted July 3, 2006 I would just get a EFI timing box that retards for running N2O and back to normal for other driving. <{POST_SNAPBACK}> If you retard the timing to a truck that already has the timing advanced do you need to retard 2 degrees for each 50 hp + the amount of advance in the truck already or just the 2 degrees per 50 regardless?
