So what that is saying is... if LTFT Lo is negative subtract fuel at that rpm... if it is positive, add fuel at that rpm... this will be in the low settings on the SAFCII... the same goes for LTFT Mid... where the corrections will take place in the Hi settings on the SAFCII... 2g's only have a lo and mid LTFT reading... 1g's have lo,mid, and hi.. So, you'll log rpm, LTFT lo and mid, knock, boost, throttle position, and anything else you find necessary. Hope that helps.

 

Thanks for the good info!

 

haha no problem.. just glad to help

 

thank you all very much
just a couple things though, my friend told me he'd sell me his neo for 250, but he said i needed a wideband for it. is that true or will the evoScan take care of it???

 

You can use evoscan without it to tune because you have access to the fuel trims, but its highly advisable to get a wideband. You'll going to need it anyway. I suggest the AEM UEGO. Its highly accurate and doesn't look too bad. Some people's brains are wired differently, but lights work better than the numbers for me. I can see if its rich=green, about right=yellow, or lean=red just with my periphrial vision. Of course it also helps if you have a helper to look at your gauges if you can't log them

 

wow this thread got some good info in it from the last time i looked. did u ever get a boost controller? i have a perrin manual one if u want to get it.

 

X2 on the aem uego, works great.

 

oh yea x3 on that aem uego. got one too

 

i actually have a home made boost controller :P i work at a hardware store and i was bored so i just kinda made one on the clock and it works really well lol

 

No comment.

I am not a fan of Tuning. I usually Install performance parts not tuning.

I avoid those computer boost gauge or whatever.

I'm into old school mechanical tuning. I prefer Carb/blower.
