I OWN A D15Z1 ENGINE AND I UPGRADED MY ECU WITH AN EX, D16Z6 ECU. CAR RUNS OK BUT I HAVE THE CHECK ENGINE LIGHT ON. CHECKED THE TROUBLESHOOT AND ITS A PROBLEM WITH MY HEATED O2 SENSOR. CAR HESITATES SOMEWHAT. CHECKED THE WIRING DIAGRAMS BETWEEN BOTH MODELS, D15Z1(VX) AND D16Z6(EX) AND THEY ARE WIRED DIFFERENTLY. IS THERE A WAY TO CORRECT THIS PROBLEM. MOVES PINS, ETC....
ANY HELP WOULD BE GREATLY APPRECIATED. THANKS

 

The z1 (vx) ECU's use a 5-wire Oxygen sensor.
The P28 computer you just installed uses a 4-wire heated O2 Sensor.
You'll need to change to this type: http://rywire.com/store/denso-4wire-...nsor-p-60.html

 

I CURRENTLY HAVE A 4 WIRE O2 SENSOR. WILL ANY 4 WIRE O2 SENSOR WORK OR DOES IT HAVE TO BE THE DENSO ONE THAT YOU REFERRED ME TO??

 

what about the secondary o2 how did you get that on?

 

I ONLY HAVE ONE O2 IN MY SYSTEM--1992

 

CAPS LOCK MAKES ME HOT!!!


sry.

 

PLEASE EXCUSE IF IT OFFENDS ANYONE. I ALWAYS USE CAPS. IT JUST LOOKS CLEANER
