Cranking Issues

Post by beng2k »

Ok, Posting for a friend, heres the scoop

R32 GTS
RB25DET S1
GT32
RC 660cc
Z32 AFM
R32 Loom
RB20 TPS
RB20 ADR
RB20DET ECU w/ Nistune Type 2

Loaded stock RB20DET ECU Address file, loaded R33 into R32 transplanted map, adjusted TPS to 0.5V and TPS idle light is on. Adjusted for larger injectors via Resize Injector function and changed AFM to Z32 with the Change Air Flow Meter function. Injector latency left as stock for now with K-const left as is adjusted with auto adjust R/T Inj/AFM change.

Car cranks but wont start. Timing drops to 5deg when cranking. Will not start. I did have the car started and idling slightly but required constant gas pedal pressure to maintain idle or it would die. This was using the RB25 TPS with the Rb25 in R32 Address file with TPS Trigger Voltage set at 0.6v and TPS adjusted accordingly. If no gas pedal pressure was used, it would lean out within 15 secs and stall.

I got my car running no problem, so much so it started on the first try, Im just not sure what else to do for my buddy.

Here is a log of cranking the car but when it wouldnt start, and for reference the MAP that was loaded onto the ECU.
