Is this thing wired right?








The problem is I'm throwing code P0102: Low voltage to MAF/VAF getting crappy milage and before I try other things I wanted to make sure the piggy is in there right. Everything is soldiered btw...

Directions to cross reference...

Road///Race
Piggy Back ECU
(U.S. Lancer OZ, ES, LS Automatic Transmission)

If I'm looking at the wirers I'm pulling the second bundle from the right...

7) Connect the Piggy Back’s RED wire to the RED/YELLOW wire on ECU pin 47. (T-into the wire do not sever it)

8) Connect the Piggy Back’s BLACK wire to the BLACK wire on ECU pin 48. (T-into the wire do not sever it)

9) Connect the Piggy Back’s YELLOW/BLACK wire to the GREEN/WHITE wire on ECU pin 43. (T-into the wire do not sever it)

10) Cut the WHITE/RED wire on ECU pin 65. (Leave enough wire on both side so that you can reconnect to both sides)

11) Connect the Piggy Back’s GREEN wire to the side of the cut wire that leads away from the ECU.

12) Connect the Piggy Back’s VIOLET wire to the side of the cut wire that leads to the ECU.





Thanks

 

I got the same problem ever since I installed my piggy. I looked at my connections over and over again and could never figure out why I was getting the cel. It hasn't affected performance in my case. I just got used to ignoring it.

 

Well I check again for the fourth time and turns out...

the purple and green cut wires were wrong! I switched them and no problems, no CEL and everything is good.

I should have a detailed "how to" soon.
