Apexi Power Fc Slight Problem

[teng]

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.

Fit the powerFC and head straight to a tuner.

No point fitting it unless you're getting it tuned to make the most of it's potential.

if your not or have no idea of tuning it yourself then its quite pointless installing and driving around in an untuned PFC.

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.
