RB25DET
z32 ecu with Nistune
z32 mafs
1000cc injectors
idle fuel pressure @ 20psi
1000cc rochester injectors
Using a z32 ecu to run a rb25 with 1000cc injectors and e85. I've lowered all the enrichment maps, lowered ttp min to 1, resized k value for the injectors and set fuel pressure to 20psi @ idle. Still after all this the car refuses to idle at anything thing higher than 10.5-11.5afr
Played with injector latency and k value with the car warmed up. After resizing for the injectors the k value is 112. I've dropped it down to 50 with no change what so ever. I can play with the latency value and it will effect how smooth the idle is, but afr still stays in the high 10's low 11's......Not sure what else i can do to lean out the car @ idle.
Tried to take the car for a spin and its bucks and spits when under light cruising. AFR stays in the 10's until about 3K rpm when it will finally jump into the 12's. Injection time when viewing in consult is 1.36 - 1.40
Use the type 2 z32 ADR to view the tune
