I have chipped a P28-A52 today. It is an automatic ECU and I have not converted it to manual yet. I didn't think to check for CEL before I chipped it (I know newbie mistake). I followed the instructions on troubleshooting by checking the resistance between set pins, I also checked for continuity between adjacent IC pins and everything tests fine no shorts or bridges. So is that why I am getting code 19 (Automatic Transmission Lock Up Control Solenoid Valve defective circuit or unplugged / defective solenoid valve)?

As for the code 20 I have no idea where to even to begin to look?

I have not installed the ROM yet and tested with the jumper closed yet.

Convert it to manual to get rid of 19.. That goes without saying.

Disable ELD when you create a ROM for it. No more code 20. Done.

I am looking for components that need replacing or places to look for problems.

I don't own a HONDA and I am working on this for a friend. I have the Engine Simulator that I am testing the circuit board before I give it back. Right now I have the J1 open so it is not even looking for the chip. I would like to fix the ELD in stock mode too.

You'll figure it out. GL
