R32 Gtst Computer Quick Question

i own a 93' r32 gtst, it has never missed a beat, on the long weekend we went down to canberra and as i entered canberra something started stuffing up it was popping and carying on and wouldnt rev over 5500rpm.

It was taken to an authorised nrma repaired and he couldnt put his fingure on the cause.

After towing the car home yesterday i have replaced coilpacks, spark plugs and i have an ignitor being posted to arrive on wednesday.

After replacing the coilpacks and plugs this problem still remains and i was talking to the mechanic and he seems to think it has something to do with the ecu as he cleared an ignition problem when my car was with him.

I was curious because he said it was a chipped ecu, and after replacing the other things i pulled it out just then myself.

It has a intec racing development sticker on the ecu and off the chip inside it has 3 wires coming out of the ecu with little connectores to join to 3 wires that lead somewere in my car these are out the other side of the ecu to were the plug side is.

What are these wires for and the wire colours are red, blue and white... What do you guys recomend? im on the verge of just buying a stock ecu and seeing what happens and how the car runs but if i do that what do i do with these 3 wires that lead somewere in my car as the stock ecu doesnt have these wires coming out will this effect the car if they arnt pluged into the ecu?

Let me know asap please.

ok i have traced the white, red and blue wires that lead out of the ecu, they are connected to a switch that was hiden under the dash the three wires are soldered onto the chip inside the ecu. i tried using the switch and changing the switch between the 2 (on /off) and its still the same im just thinking weather this on/off switch is for the chip and switching between the stock ecu mapping and the chip's mapping?

ok i just think i found the problem. the ignitor sitting ontop of the rocker cover i think is the problem. i just tried starting my car n it would crank then die crank a little more n die like it has a flat battery but it doesnt lol. i unplugged the ignitor tried starting it and the cranking of the engine was normal speed but obviously couldnt fire up cos i had the ignitor unpluged. then i pluged it back in and it started f*king up again when trying to start... my ignitor arrives wednesday so we will see then but im pritty sure its that from what i did but its very hard to explain what actually happens over the net

      Question about BoV on RB25DET NEO

      By MBS206 · Posted

      Never an issue with boost control. No weird boost issues pre throttle at partial throttle like you're suggesting. It worked.   As for all the turbo damage claims, they all were started by aftermarket BOV companies. At least turbo timer companies had SOME truth about them, except people failed to realise that except for in extreme circumstances, that small amount of driving you do to park/ through pit lane etc, is enough to not have a need for a turbo timer.

      Question about BoV on RB25DET NEO

      I tell people all the time this stuff runs on a 2 MHz 8-bit MCU. The math is a bit arcane, they do a lot to get around their limited resolution and so on but it works great as-shipped. So if an 80 to 160 MHz modern 32-bit MCU can't make it work you've really screwed something up badly. Your average graphing calculator is faster these days, god forbid we start talking about what's hiding in vapes or some stupid internet-connected "smart appliance".  I suspect the lore about off-throttle surge damaging turbos must be very, very old if it was ever true. I still don't think off throttle surge is good for turbos because you're rapidly having air going in and out of the turbo on top of rapid loss in shaft speed which presumably does impart some kind of unusual load on the rotating assembly. As for the recirculating valve, I believe Nissan actually in a press slide deck of some kind explained for the RZ34 they found it improved response. Prior to that they kept the throttle cracked open instead which causes rev hang and because the throttle/engine is a substantial restriction a ton of the energy in the air stream is lost just to pumping past it. Recirculating helps reduce energy loss by bringing the intake side of the compressor up in pressure so it's not working as hard to pull air in. In DCT cars where they can slam gears I believe Porsche hangs the throttle wide open with no fuel injection to keep turbo RPMs as high as possible during the shift. As for running post-throttle boost source, I would be concerned that at partial throttle on boost you would have driveability issues. It would be constantly trying to run crazy amounts of boost before the throttle to compensate for the throttling effect. Maybe with a much more sophisticated boost control setup you could activate a solenoid that goes from a conventional 3-port setup to something that allows the wastegates to see full vacuum in that specific case?

      Blue/grey smoke after idle

      By MBS206 · Posted

      Did you clean everything out? Take all intercooler piping off, empty the intercooler of oil, clean the exhaust out, etc? Intercoolers make great catch cans... Which makes them less useful for intercooling... But very worth cleaning out, along with all adjoining piping.

      Blue/grey smoke after idle

      By pacman_1219 · Posted

      Update Got turbo back from hypergear, installed everything etc. Bled coolant, wasn't smoking so I thought beauty she's sorted now. Went on a drive, car up to temp, let it idle for about 15 seconds, gave it some gas...nice puff of smoke again. Fml No doubt my turbo was pretty worn anyway but nonetheless frustrating that the problem persists.
