Title: stupid issue.... I CAN'T FIGURE THE BITCH OUT
Post by: d-rail on May 05, 2009, 07:38:26 AM: I got an issue with my car that's driving me mental. I can't figure this stupid shit out. It's a d16z6 with nothing but aftermarket guts but I have a stock ECU on it. It will not rev past 4600 RPM now. I can't figure it out. Hears a video of it. It doesn't sound like it but it's actually bouncing off a rev limiter here.

If you have any ideas PM me or PM me and I'll give you a number a reach me on

Post by: Conceptz-X on May 05, 2009, 08:31:25 PM: Injector grounds? Bought my 83 supra doing some shit like that for $300, turned out the injector ground was loose

Post by: d-rail on May 05, 2009, 09:18:15 PM: Theirs no check engine light and the car runs great till about 5100 rpm then it hits a rev limiter I've changed the ecu in it before with the same results.

Post by: chris on May 05, 2009, 09:40:24 PM: Maybe swap another dist on the car.

Post by: Zeniceguycrx on May 05, 2009, 09:45:41 PM: I had the problem when I did the DPFI-MPFI swap, turned out to be a bad ECU
I would also look at the TPS sensor and wireing

Post by: d-rail on May 05, 2009, 09:57:36 PM: When I get back from Ft. Gordon, Georgia I'm gonna have my buddy bring his distributor, ecu, and wiring harness and start going through the thing. Thanks for the suggestions guys

Post by: chris on May 05, 2009, 10:00:10 PM: Also clean all your grounds
Title: Re: stupid issue.... I CAN'T FIGURE THE BITCH OUT
Post by: d-rail on May 05, 2009, 11:07:10 PM: I think all my grounds are new. I've replaced 3 for sure but I haven't touched the ones on my thermostat yet.

Post by: chris on May 05, 2009, 11:24:48 PM: thats the one that causes wierd problems with the ecu and blows fuses etc
Title: Re: stupid issue.... I CAN'T FIGURE THE BITCH OUT

Post by: chris on May 06, 2009, 09:53:45 PM: also make sure you have correct fuel pressure. if you have a walbro tank it will want atleast a 1/4 tank of gas or it will run like ass or not even run/start

I hope you have a fuel pressure gauge they are cheap and a great tool to verify you have correct pressure etc. Nice little tuning tool also if you max out your injectors on stock pressure and you have an adjustable fpr crank that bitch up and vroom mo powa
Title: Re: stupid issue.... I CAN'T FIGURE THE BITCH OUT
Post by: d-rail on May 06, 2009, 10:10:34 PM: I haven't changed out the fuel pumps yet. Been wanting to do one thing at a time and get things figured out before i start pulling more shit apart
Title: Re: stupid issue.... I CAN'T FIGURE THE BITCH OUT
Post by: chris on May 06, 2009, 10:40:15 PM: check your fuel pressure
Title: Re: stupid issue.... I CAN'T FIGURE THE BITCH OUT
Post by: d-rail on May 07, 2009, 10:22:04 PM: put fuel pressure gauge on checked ok, changed ecu, distributor, engine harness which sucked doing but still had same issue. WHAT THE HELL?!!!

the ecu is telling you "wtf is going on!!?!!?"

ECU is not throwing any codes. Put my ECU on my buddies car and it ran fine. I'm gonna switch all my sensors out on my intake whenever I put my ported intake and throttle body on it tomorrow.

Post by: DmC on May 08, 2009, 11:23:42 PM: Dude change the ect to it's one of the few sensors that can cause that shit.
