92 JDM , intake mod only.

Had the car for 3 years and it had been running fine all along. I finally decide to pick up a PFC from japan.

I installed the PFC. Connected the battery and tried to start it up. It wouldn't really fire up, it would just crank and then die. I tried to give it some throttle and it didn't help. Gave it a few more attempts with no result. I initialized the setting from my commander and tried. Same result.

Now the problem is that I plug back in the factory ECU. Fired it up and if I let go the pedal, it would die. Sounds like it's running on 1 rotor only. (it is my guess only, since it sounds a bit different than normal). I hold my foot and let it rev at 1.5k rpm for about 5 mins, not helping.

Not sure what parts I have broken in the process. I appreciate any suggestions/helps.

I think the first thing I should do is get it back running normally with stock ecu. But with the PFC with me now, what kind of info i can get (such as checking the sensors, etc from the commander) could help me diagnose the problem?

Thanks in advance.

Turns out that I didn't notice one of the wires got loosen up when I was pulling the harness from the factory ECU in the first place. Thats why everything would not work. Problem fixed.
