Hondata

Anyone come across the car stalling once u sellected the o2 heater box and not starting again?
I tried the stock ecu it will fire the car but it runs super rich cause of the injectors but the hondata wont start but will turn over. tried different maps and nothing.

Hey, did you figure out the problem with your s300? I recently had a very similar issue but figured out the problem. If you still havent figured it out let me know.

More than likely you have some kind of wiring problem in the car. You may have the O2 heater output connected to something else.
