what ECU are you using?

dougshatch

PM9 ECU

Crx Jimmy

are you obd1 or obd0?

obd0 i swapped D15 Vtec but i change the mpfi to dpfi

HondaPartsHero

the PM9 is obd0 so it only looks for a one wire O2, you can't convert it unless you have converted to OBD1

dougshatch

i know i have 1 o2 sensor wire and how can i converted it to obd1 o2 sensor cos it have 4 wires

dougshatch

or i can buy the obd0 o2 sensor and it would be fine is that right?
