My car is a 98 Integra-OBD2.

I bought the obd2-obd1 conversion harness and will be running a p28 with Hondata S100.

Because I am NOT running the secondary 02 sensor, my STOCK ecu throws the CEL light.

When I plugged in the p28 (to check if everything was working), my CEL was still on. I was told the OBD1 ecu does not detect the secondary 02.

My question hereinlies; <U>How do I determine what the code is for the CEL with the p28? </U>

I'm a noob, so please, be descriptive!! I'm getting my car dyno tuned next week so I want to make sure I know what is going on with everything.


Please help me out.

 

I took my car in to Autozone to figure out the CEL on my STOCK ecu. Originally, the reason my CEL came on was due to the lack of the secondary 02.

NOW, the CEL is on because:

1. Idle Speed Control
2. Ignition System/Misfire
3. 02 Bank 2

My thoughts:

What can cause the idle speed control to come up? When I first checked why my CEL came on, I was on my stock TB and the only code that came up was for the 02 sensor.

1. I'm running a JG tb now. The thing is, I have to adjust it so that the butterfly DOES NOT CLOSE all the way when I do not have my foot on the pedal because it will stick. Could this be the reason for the CEL?

2. my car has a JRSC. I'm running BKR7E-11, gapped at .30. Could it be something to do with my s.plugs?

Agian, i'm getting my car dynotuned so I want to figure all of this out. I want to get these two things taken care of first before I plug back in the OBD1 ecu.


please help.

 

before anything happens and u dyno, compression check first.......... don't even go waste your money if your engine is not in good working order.
