I was going down the road with the box set on 100hp decided to trun it off, I seem to get better milage that way. Anyway afther I turned it off the check engine came on and the trk was rattling bad did a restart and it settled down. But the box would not come back on, pulled the codes this morning and they are P0237 & P0192 now I have know ideal what these codes are but the box is now working again the engine light is still on this is the first time it has throwed codes in the year I've had it. going to check connections and see if it's going to give me promblems. When I fir [eyecrazy] st got the box the wiring harness was bad they sent another one and promblem solved. Was wondering if the codes go away are is the someway you can clear them such as disconnecting the batteries? Thanks ABB

PM qzilla. He's here all the time....

Make sure the connector is seated all the way in the box, poss you had a intermittent connection there. Mine did the same thing .

I had the same thing happen to me with my box...My truck would cut out real hard and had a major loss of power when this would happen....I would have to unplug the box and then plug it back in to make it run right again.....I sent back to quad and they took the data link connector off and installed a wire that directly connects to the fuel position sensor wire....Got it back about ten days ago and it has been perfect so far....It seems like it has more power on the bottom end also!!!!
