Take apart the ECU and see if any capacitors are leaking.

Tested with 6484 ECU, same check engine lights and ABS sensor. The new foreman did tell me the wiring harness seems to have been cut. There’s one open cable near the intake manifold .

Earlier I also wanted to ask about the wire harness, because even my mechanic who did my car transplant need to send to expert wireman to do the wiring.....

Now sending to a perdana expert. Hopefully can resolve this issue. Really feel the power is much less than I expected. Almost the same as before.

Just an update. Problem solved. Sent to another perdana expert. Changed a couple of items including the air intake. Now all is good. Thanks guys.

The air intake very very sensitive. I remember got one time I wanted to try open pod, so got the adapter, but one corner of the fit was like less than 1mm off. The car starts and run but once you want to accelerate it chokes. Remove fit back original no problem.....lol

I see. He changed a couple of items too. Looks like something called the Power TR in addition to the ECU. Also added quite a few air hoses to plug here and there, I’m guessing for reading/sensor.
Now looking to upgrade brakes and exhaust. Brakes if get VR4 or EVO won’t have to do custom bracket?
For exhaust size 2-1/4” enough? And what’s a good muffler to use if I want the sound to be just abit louder and bassy.

Your original brake is single pot? VR4 ones are double which was a improvement for me since my original was single and I transferred the servo also which was twin layer. Brake pads I am on Trestor Advantage pads.
My exhaust is 2.5" all the way until the muffler which is straight through. Some say can go up to 3", but better ask the pro exhaust guy.
Since you are fitting the muffler new, there is one now which you can switch the straight through on and off, meaning if don't want loud can off......lol

yeah now still stock single pot. If I changed the calibers and rotors will it cause the brake to feel more “mushy”? Or is that the reason to change the brake servo together?
Do you mean like a valvetronic exhaust? Would be nice to have haha

Brake servo aids vacuum so you get a stronger brake force. If changing to bigger rotor and larger calipers, best to increase the servo size too.
Yes, I think they call valvetronic exhaust....
