i swapped Vtec D15 obd1 and change the mpfi to dpfi and i cant get em idle right does that becase o2 sensor isnt connect at all? i have 1 wire from obd0 o2 sensor and d15 obd1 has 4 o2 sensor wires, how can i converted it?

 

what ECU are you using?

 

PM9 ECU

 

are you obd1 or obd0?

 

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

 

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

 

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

 

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