[Chi100188]

Hey guys i just nismo installed 740cc injectors and i can't get it to idle? it sounds like a RX7 lol....but yeah here are my settings for the new injectors. My ECU is a Power FC this is for the RB25DET

No.1 50.1% -0.14

No.2 50.1% -0.14

No.3 50.1% -0.14

No.4 50.1% -0.14

No.5 50.1% -0.14

get a tune.....

[Chi100188]

so theres no way i can set it to make it sound/idle just a bit normal?

[Chi100188]

anyone?

[Dearlove]

be patient dude, some one will know

[180or200]

try 60-65% and 0.18

[Chi100188]

how did u get that figure mate?

[180or200]

it will add fuel so dont stress,

my 740's were set at 65% AND 0.18 is the correct lag time

it will be rich but that's cool, just try it, can't get any worse can it?

[Chi100188]

alright cool mmm my power FC was resetted....because i couldn't change the injector settings so do i have to redo the idle setting again and then do the injector latency or should i do the injector latency first?

Cheers

There is a thread called "injector latencies" do a search.

[Chi100188]

i've doen a search already mate....it only comes up with 550cc.....i wouldn't of opened a thread if i could find my answer lol

[180or200]

yeh I know, the isn't much around on 740's but plenty of people have set them to 0.18

try 50 - 55% and 0.18 first see how it runs, i know i said 65% but that was when my latency was at 0.00

and yes i would adjust before starting

[Chi100188]

hey i did above settings the car won't crank over its like trying and trying and also the knock goes to 50 so have i stuffed something?

[180or200]

you mean it wont start or it wont crank?

most likely fouled plugs

[Kaido_RR]

chi,

if i remember right i had them set at

60% and 20ms.

if the car isn't cranking as mention you might have foul the fuels. What is the idle like? are the revs lumpy or does the idle sound alittle ruff?

[Chi100188]

when it was idling it was super lumpy heheh rough as mmm ill change the plugs tommroow is that 0.20ms or 20 ms? lol and is it + or - mikey

+0.20ms

mine idle was alittle ruff but never super lumpy. might if you reset the pfc you might need to do redo the idle setup (10mins with aircon off, 10min with aircon on etc)
