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.

    • Crazy how good the aero bar looks compared to the stock one
    • Yes, but you will need to rewire all the things that are different. CAS, coils, etc. Yes, but there is no IAT. What? You can use anything you like. It just has to be hooked up so that it will work.     Or are you wanting to just plug and play without having to do any thinking/work?
    • It's been a little over a decade since I bought the S15. As I did on my socials, I'll share some of my favorite pictures from over the years further below. If you haven't realised, pretty much all the pictures in my posts are ones I've taken.  In terms of updates, I don't have pictures, but I acquired a near-perfect pair of fog lights from a friend of mine, so those got swapped in for the pair I already had. As for the JZX110, I just got it back from being fixed. A few weeks back, I was on the highway when I suddenly drove over something with very little time to react. It was probably the size of a soccer ball, but it went under the car and banged into the underside pretty loudly. I pulled over and realized the fluid leaking was fuel, and of course, it was right near my exhaust. This required replacing the fuel tank. If you happen to be in the same predicament, thankfully this car shares a fuel tank with the JZS171, IS200, and IS300, so it wasn't too painful to replace. Enjoy some pictures as mentioned above, including the carnage from the fuel tank and a bonus picture I came across which shows how ridiculously shiny the Bugels are on the 110. So many more pictures I could share of the S15 but this will do for today, enjoy. 
    • Welcome.  Was the mistake the car, or joining us? 😏
    • Yeap, was me and the daughter getting coffee before heading to the new joint to measure up the fridge space and taking some pics that the solar installer wanted of the switch board
