Daughter card

[jumpbluesdude]

I put a new motor in my truck because the old one was pretty tired. After the motor was in I was driving it and the motor torque twisted the motor up and the fan hit my radiator hose and cut it. Coolant went everywhere, but I was able to get it to a parts store before it got too hot. I changed out the hose, but it hasnt run right since. I hooked it up to tunerstudio and the O2 was all over the place. Everything else was normal and working fine. I pulled the relay board to clean it up and found coolant in the joint of the mating 37 pin connectors. I cleaned it all out with alcohol and now there is no O2 reading. I traced the signal to pin 23 and there is a signal being sent up to pin 23 on the megasquirt. I took out the megasquirt and put it on the stim to trace out the O2 signal, which ends up at pin 13 of the daughter card. It then goes into the middle surface-mount chip (pins on all four sides) on the daughter card. I can see the voltage hit the pin on the chip, but the gauge in TS just sits at 11.5 AFR. Am I just screwed and have to buy a new daughter card or is there something I am missing? Thanks.

This could be a settings issue - try reloading the firmware and loading an older tune. See if that changes it.
