Carrera95

I seem to be having an issue with my a/f guage, it works completely fine with the stock ecu. When i start the car with megasquirt the afrs on the gauge and in megasquirt are pinned at 22.4, the car idles rough but it surges up to about 2k rpm every 2 seconds or so and the afrs will drop to 18ish and then back to 22.4. I already calibrated the gauge (Innovate MTX-L) so 0v is 7.35 and 5v is 22.4 like the manual states for the yellow wire outputs. Another thing i noticed is when the key is on the sensor will heat up and start reading max lean but once i start the car, the gauge will start heating again. I don't believe this was happening on the stock ecu. I'll attach a datalog after i take one.
