injector adjustment on Power FC - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Hey Gurus.

I've just installed my sard 850 injectors on my redtop sr20det and the lag time on them in .85ms. I have a power fc and was wondering how i input or what to input in to the the power fc in order to compensate for the larger injectors until i get a tune.

370 / 850 = 0.435 (round it up) enter that for each cylinder

S14 370cc injector lag time is 0.58ms

so. 0.85ms - 0.58ms = 0.27ms new lag time

enjoy!

i was under the impression that the lag time on the stock 370cc injectors have a lag time of .64ms no? where did you get the .58 from.

thanks for the responses

.58 for stock injector
i'm positive

SoguRacing · 07-18-2008, 07:15 PM

ok so, i got my injectors installed and my z32 maf installed and the adjustments accounted for within the power fc. i started the car and it runs like shit.

Did you only do the correction and it runs like shit underload or idle?

SoguRacing · 07-19-2008, 02:08 AM

didn't put the car under load. the idle was bad enough to keep me from going any further.
