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

No.6 50.1% -0.14

The negatives might be positives

any help would be good :)

Cheers

Chi

alright cool :P 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

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

when it was idling it was super lumpy :down: 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)

    • Yeah, the thread is only nearly 20 years old.
    • Been down in Tassie for 2 weeks (a cruise, not a race for once) but spent a little time on her when I got back. I worked out the injector settings in the PowerFC were not correct for nismo 555s, set those to 66% +10ms and added a little air at closed throttle, set the timing (approximately, because it has some weird non 15o cells around idle) and now she starts and idles properly. She purrs like a kitten (ignore the co2 alarm in the background, I did  ) 20250518_171052.mp4 Next step, off for run-in, tuning and alignment!
    • Went to a drift practice day at a local circuit (held on the reserve parking area behind the grandstand) for the first time in about 15 years. Some kei cars were drifting as well, a not so surprising Suzuki Carry truck, and two 1st gen Daihatsu Copens that were converted to rear wheel drive(!) using Daihatsu Boon X4 transfer case, prop shaft and rear diff, obviously omitting the front driveshafts. They looked really fun to slide. I heard that they cost "about half" as much as a Nissan Silvia etc to run.  On the track 'Tech M' a local BMW tuning garage had a customer track day. Mainly recent models but there was one E36 which looked ancient among all the current models. It was cool watching the drifting and then turning around and seeing random people thrashing their M3/4s  central-circuit-drift-practice-2025-05-18-long-yt.mp4
    • I prefer it with those wheels (sacrilege?) 😋 Here's a photo of a fully original one for reference. The price is $350K....
    • I would like to keep it around 15k but if I need more to make it reliable and not have to worry about the car breaking I can go more. It's my project car so I'm just trying g to figure out what needs to be in it i know basic things like turbo cams injectors I'm just unsure of the size and the specifics so I'm spending alot of time on Google and its mostly rb25 and rb26 not alot on neo
