running mega rich

[bobo]

hi guys

I installed nistune to my rb20 , resized the injectors and afm, but it just running so rich it will stall after a min or two then wont restart.

what is your new injection multiplier?

what injectors and AFM did you resize to?

what afrs are you currently getting?

[bobo]

injectors at 131

i have nismo 555 and a z32

af/r is 14.7 all red

[Matt]

I meant AFRs at the exhaust pipe with your wideband

Okay doing the resize here resulted in 208 K constant. Something went wrong

I attached what I did with the automatic calcs to get you started to this post

Matt why doesn't the injector latency change when u do the auto calculations? Stock the latency is 760us, change to 720cc or 550cc and it still stays the same?

[TM_S13]

that would be because each brand of injector has it's own latency value...
that's why some of the generic chips state that they will only work with "that" specific brand of injectors...

I still don't get it tho, Stock SR20DE injectors show the same time 760us and so does stock RB20DET injectors 760us in Nistune?

thanks matt i synced your map it's idling better now. but i think its best and safer for me to take it down and get it profestionly tuned at the workshop instead of me playing with it to much lol but atleast i should be able to drive it their.

good idea!
