I have a stocker r33 gts25t with a nismo muffler. Now i know that the Power FC will work out of the box on a standard ECR33. 10mins initialisationfor idling, 10mins initialisation with aircon on, 10mins initialisation with dehulidifier on then the idle initialisation is complete. Now when i take it out for a drive, stepping on the accelerator makes a weird small noise from the engine. I cant make out what it is, possibility knocking, or hunting (whateter that means lol). The original oem ecu doesn't cause that noise. May i know or does anyone ever encountered that problem before. I took the Power FC out and back to oem afraid that it it is knocking, then my engine would be dead in a few days time. lol

Btw, i did do a full reset before i did the 30mins idle initialisation.

Dude, I believe aftermarket ECU's from japan that come with ignition maps are based around using 100 octane fuel (readily available in japan)- if this is so just plugging it in and driving you'll have too much ignition advance (unless you have 100 octane fuel available?)and it's gonna ping=engine rebuild. Last time I checked a decent tune was cheaper than an engine build. If you bought the thing make use of it and get it tuned on a dyno, and do fill up with the highest octane fuel you can (readily!)......

Well, fuel is cheap here anyways and my skyline uses RON97 Fuel (all the petrol pumps in the country has RON97). I have to replace my coilpacks to splitfires before i go for a tune as my tuner is like 130km away from where i live.

Attached are the readings i had before i pulled out my power fc.

My exhaust manifold is bent and leaking air so that was replaced today.

    • Yes to both! Yes to standard ECU and tune, but exhaust is aftermarket. Unsure on brand. Actually have it sitting in at my desk haha! I have to set it up on my laptop but this is a great next step, will do. So I generally try to shift before 4.5K RPM most times. I largely don't do a lot of high-rev driving, but I will take it up to red 1-2x a week max, as I know the occasional "Italian tune-up" is good for these cars.  Oh wow, is this way better than what I'm getting. Does this mean there's a good chance I have an issue?   Thanks for all the info so far guys.
    • Old Son, did you re-use the Holden ABS in the new shell or try a different module?
    • Yeah, nah. I had the actuator rod off it today. The arm will not move at all. Neither out, nor in. Yeah, you'd think so, but I've been thinking about that. Even when the actuator rod fell all the way off at the beginning of this saga, it would build more boost and faster in lower gears than it would in higher gears, and you'd think that that was the opposite of what should happen. But I strongly suspect that there is a thing with the gearing getting the revs to rise faster, that there must be some transient effect with the gas flow rate rising quickly, that you don't get with the more steady state case of the higher gears. Keep in mind - the gate is not shut in either of my weirdnesses. So things are not "normal". We normally think about a turbo spooling up (below the wastegate target) with the gate shut. I have all sorts of mental models running now where the gate is a little bit open, and having it stuck open allowing gas out while it should be going through the turbine has all sorts of weird effects (in these mental models). I'm thinking in the higher gears, the ex mani pressure builds to the point where enough gases spill out the wastegate to just prevent the pressure rising much more at all, or just creeping up, all the whole the revs are increasing and getting closer to the point where a gear shift becomes necessary.
    • Is it possibly wastegate actuator itself is sticking, or even the rod to flapper? Otherwise I reckon things are getting a bit rusty/worn   Also odd it won't boost in 3rd to 5th, but will in 1st, I'd expect the other way around with it slightly open as there's more time on your way to redline for it to spin up
    • Does anyone know ow what these two plugs are for and if they should be unplugged? Just put the dash back together and can't remember if these were plugged in before or unplugged! (Blue and white plugs) 🤦🏽‍♂️
