Hey Guys, this might not be helpful at all but my car does this too and today i tried something different. I didnt let the fuel pump prime and the car started fine.

May have been a slight studder but way better than usual, but my car is stock so don't know if it helps. No mods stock ECU.

Could have just been a fluke but might be worth a shot and it backs what DVS is saying about it being too rich (too much fuel at startup). The Fix who knows lol

Same, the less i prime the pump the better it starts. If i prime it 2-3 times its like a f#ckin steam train. Just chugs and then stalls.

Yeah Sarge, i always get different out comes from it but the best is just starting it as fast as you can. I really think its to do with fuel but i have almost everything new on my car ... only thing is injectors i got them with low KM but im worried they are leaking but you also have changed your so hmmmm

just thought id put my 2 cents in ive got a r33 gtst 4 door and ive got the same problems as all u guys my car got high flow turbo, exhaust, fmic, and bosch fuel pump. Its still running stock ecu and stock injectors ive just replaced the spark plugs ive also got bigger injectors to go in it im wondering if i put in the bigger injectors am i able to get the stock ecu tuned or do i have to get an aftermarket 1

Nistune can run any basemap you want, in your case a Z32 or RB20 ecu with Nistune daughterboard inside can load a R33 RB25 basemap. Both these ECUs are direct fit, just that Z32 one has VCT control and the RB20 one doesn't.

    • To be determined, Luke, to be determined. 😁 Definitely the car
    • It might be worth having a good look at the chassis behind the bumper then; most people prefer the series 2 look so it might have been changed to cheaper parts as part of an earlier repair
    • The car itself a series 2. I was just curious about the headlights and just wanted to confirm that they were series 1. Good to know the rest of the front end is series 1. It’ll be easier for me to find parts on the aftermarket side of things lol
    • If you've wired up the coils & injectors properly, & have the neo CAS loom for the trigger, it should all work. The VCT works the same way so just different plugs between s1 & neo. Assuming DBW if no IAC. Don't bother with the stock boost solenoid with g4x.
    • THERE IS NO IAT SENSOR ON ANY SINGLE TURBO RB. And the one on an RB26 is not for "engine control" - it's really too big and too slow and is only used for over-temp alarming (as far as I can tell). Anyway, you don't have one. You want/need one for the Link, then you need to buy one, find a spot for it, and wire it in. You do know that the stock boost solenoid is not capable of "control", right? It is merely on or off, for the low boost (5 psi) and high boost (7psi), which the ECU enforces mostly based on gear. The stock solenoid is not for PWM control and is not plumbed up in a way to provide it. If you want to control boost properly, then you need a proper MAC valve. And yes, you can wire either of them direct to the ECU. Well, I assume you can - I don't know what the boost solenoid pins on the plug and play Link are capable of. They really should be as capable as any normal Link - but seeing as it is plg and play, it might be limited to stock functionality. Read the doco.   You really do just want to plug stuff together without understanding how it works, right? I can't help you there. I don't know the plug types or pinning on half the stuff you're asking about. If I had to do it I would sit down with the wiring diagrams, the car/looms and a multimeter and work out what is what.
