As someone might remeber I am not experienced with efilive tuning but successfully tuned the same car with efilive following the calc vet tutorial and som help from this forum. I was running very lean after mounting headers and exhaust. That was a couple of years ago, and now Ive finally managed to find time to bolt on my supercharger.
These are the questions that I need help with. At least for a start.
Do i need a xx03 custom OS? If so, do i need to disable MAF? I know the Custom OS tutorials says so. But for a start I will like to keep boost low and most probably way bellow MAF limit
What do I read to start ?
Anyone having a tune file I could start with ?
Ignition map??
I have the 12609749 injector so I used data from a 09 6.2 flexfuel. For the TMAP i have been told to use 223.43 and -7.88kPa offset to scale it correctly.
Started the car for the first time tonight. Still have to put back a few pieces but could not wait to see if it started with the "pre" charger tune. It starts, idles good for a few seconds, ten richer and richer until it suddenly gets really lean and stops. Did not touch the accelerator, so I do not know if I would be able to keep it alive.
