Tell us a little about you. What cars you are interested, where you are from and why you are interested in learning to tune.
Current car is a r33 gtst running a RB30/25 Haltech ps2000 Garrett 35r etc. built by myself so safe boost levels for now, lol
Just wanted to say what a great website this is and I have learnt a lot with heaps more left to learn,
Probably not the easiest car to learn with but nothing beats jumping head first,
I might ask a quick question while im here im running a AFR of 13.7 at low temp idle seams happy there but I noticed injector cycle duty is at 1.5% with bosch 1000cc injectors and 2.5 bar base fuel pressure, 98 pulp (pump unleaded petrol)
Does this duty cycle seem ok?
that duty cycle is about the same as what I get, mind if I ask, why such a low base pressure?
At this stage its still only early days, but At this stage I have just left base fuel pressure at 2.5 bar to try and get the most out of the pump.
I am looking at running a 2nd in tank pump with some decent fuel lines in the near future,
I was thinking maybe until then going up around the 3 bar base fuel pressure,
To try and help stabilise low rpm AFR's and see what affect it might have on starting,
As starting takes quite a number of cranks hot and cold,
