thanks man, i totally thought i was going to flamed for this, anymore info would be great.
the reason is i have a calum basic, (b14 ecu) that is running my ve, this winter i am doing a bunch of head work.
I bought a wideband (aem) and like the car a/f is great,
at idle its 14.0-15
normal driving its at 14.7
wot its at 13.5-13.7
nitrous i have it at 12.7-13
I am installed n1 cams, Valve springs, camgears, bigger shot of spray and i wanted to tune the ecu for N/a and use my apexi for the nitrous tunning, but if i cant i will need to just write the adjustments down for the nitrous and when i go to the track use it. Mostly its to up the Rpm range cuz of the n1 cams, its set to 8100. I know after that the ecu will just read fuel maps for 8100. so after that i can use the apexi as well.
Or install a greddy emanage blue and have that tunned or just see how it is with no changes.... so i am sitting on the fence here
thanks guys
