I have 2 months fighting with a ECU error #9 in a P72 B18C1 with Hondata. I know that the error #9 is the No. 1 Cylinder Position (CYP).

I make all the manual troubleshuting, cut the hondata jumper (return to OEM), n-check the ground wires, change the distributor with other car, change the ECU, etc, etc, etc and the code remain. I lost my time and mind with this problem...

The car have good iddle, start good, I dont have clue with this.

PLEASE HELP, ALL IDEAS ARE WELCOME


Thanks in advance,

Dariusz
