Ok so i installed my safc-2 a while back but finally drove the car the other day and now i keep popping a check engine light. So i scanned the system and got a p1128 which deals with the A/F system. The car still runs great and has not effected it in any way. So do you think either it is a bad connection at the ecu or the wire going from the safc-2 to the ecu is throwing off the current so the ecu thinks something is wrong?

I do not think there is an issue with any of the O2 sensors i had no check engine lights before this install so thats why i am narrowing it down to the safc-2. Just wanted some peoples opinions before i tear into it tonight.

Thanks guys

 

did you setup your Safc-2 correctly?
Maybe the value you put was too large for our ECU to handle, and it throuws the CEL.

 

Ive done the initial setup copied from javageeks install but i havnt changed any of the extra values yet was going to take it to the dyno to fine tune the system.

Oh ya and the install was super easy thanks javageek for the DIY!

 

If you have all the values set to zero, then you probably have the wrong sensor type entered. Or you don't have the MAF wires hooked up correctly.

 

Ive done all the base values... i just havnt gone into the rpm values yet to start changing fule curves or anything at this point.

 

Go in there and make sure they're set to zero.
