I just finished my swap..WOOT.. :dance: The check engine light is on and i want to clear it.

K-pro says:
Code
39-1, is the serial communications link malfunction.
41-1, Heated oxygen sensor heater circuit malfunction

How to i fix these?

BTW, did you guys leave the multiplexor enabled? It didn't make a difference but seeing but other people are using.

I have a k20a2 swap in a ek using the map for k20a2 stock.

For the Code 41-1, shouldn't just turning off the O2 sensors on the K-pro fix this?

Multiplexer - from the help file:

Multiplexer enabled - Enables/disables the multiplexer, which communicates with the rest of the vehicle. Only disable this for engine-swaps where the vehicle does not have the multiplexer unit in the fuse box.
O2 heater - if you have an o2 sensor, your wiring is not correct. If you don't have an o2 sensor, I'd suggest you get one unless it is a race car.

Waiting on the exhaust parts to get here, and i still have to assemble the axles. Hopefully it'll be hitting the road in mid april or so. AutoX season already started and i don't want to miss too many events. :mad:

Guess I'm gonna have to call hybrid racing tomorrow.

Would this be caused becuase of an open header and no back pressure? I haven't had the chance to run the car for more than a few minutes at a time.
