Ok, lets see if I can explain this cleary I have just recently upgraded my fuel system again, and since putting in the powerfc injector settings the car wont start. ( R32 GTR RB26 )
The car was running nismo 600cc injectors and now I am running the Sard 800cc twin sprays.
Using the properties for the injectors:
Stock Injectors are 444cc/0.77msec latency
Old Injectors are: 600cc/0.81msec latency
New Injectors are: 800cc/1.10msec latency
The oringinal settings for the 600cc's on the powerfc were:
Injector- 74% (444/600) Latency- +0.04 (0.81-0.77)
that obviosly ran fine....
soooo, first try I put in the settings for the new injectors
Injector- 55% (444/800) and Lantency- +0.33 (1.10-0.77)
...........doesn't start
so I thought.... well its tuned for the 600s, so maybe I'll do the injectors corrections for them?
Injector- 75% (600/800) and Latency- +0.29 (1.10-0.81)
...........doesn't start
so now I've checked fuel pressure in the rail and going by the manual of 42psi, its all there, holds pressure on purge and cranking...
am I doing the injector corrections right??? The battery is now being recharged from been drained flat from cranking and purging pumps, so I'm trying to find if I'm missing something.
