Have put 740nismo injec. And twin afm stillin unit. Doubled value with change afm option. Made k value 288. Runs very ritch. idels ok holds limiter fine but fuel floods out exhaust. I just want to lean it out. Its just burnout car got a event this weekend need running bit better.
Read the nistune basic tuning for 3rd time. Thinking need change injec latency. Dug up some info. 75 stock. 77 555cc 83 740cc I'll give that shot this arvo.
Nistune in South Aust Kaza, have u tried talking with the guys at Nistune, the are fairly helpful in working out the correct settings for the type of injectors u have. I'm sure a couple of probing emails to them might get you the answers your chasing. cheers Dodgey ( aka Rob )
waiting to hear back from them. though think made a mistake not unclicking adjust ttp min and max limits.
Problem solved. Nothing to do with my tuning. Injectors didnt seat in 300 degree rail. Should of pressure tested it.
