Negative LTFTs means that its running rich and trying to pull fuel from the VE to lean it out?
Positive LTFTs means its running lean so its trying to ADD fuel to the VE to richen it out?
sorry, its just been FOREVER since I've been tuning... just trying to remember
I'm sure I'm right
1) When trying to tune VE we reset the computers old programmings(LTFTs/STFTs)?
2) Drive around for a couple hours or days to let it relearn LTFTs/STFTs.
3) Then we log in SD mode(no maf) correct? So that it runs only off the VE table? for 30 minutes to 1 hr.
4) We use the SD log to correct the VE by using the LTFTs we got during the SD mode?
Correct?
