I installed the V2 piggyback auto version on my 05 lancer and I drove it for around 70 miles and a CEL code came up, it was P0102 I think Mass Air Flow Sensor Bad?? I noticed the mass air flow has wires comming out of them and one of them was the white and red one that I think is the same one I had to cut to attach the piggy. I reversed the 2 wires that I had hooked up to that white and red wire and the code went away but the car runs perfectly normal, it dosent seem like it is in learning mode and I don't notice an increase in power or anything, so I don't know if I have it hooked up right or not??? So is the Mass Air Flow CEL normal or did that mean it was hooked up wrong?? Is it normal that I don't feel too much of an increase, will it just take a while to happen?

 

PM ROCK on here, he would know. I don't know about the V2, I have V1 and I also get P0102, so it could be just the MAF or it could be related. No idea, the V1 and V2 work differently

 

the only confusion I had is where the green and the violet wire go. It says attach the green wire to the red and white wire going away from ecu and violet on half going towards the ecu.
