Re: Need some help with tuning.
There is a box called "Rolling idle RPM" on the idle tab. You have the entire table 0'd out.
As for the 02 codes; my DTC list doesn't even show them, and I have an 04 P59 ECM. When you idle, are you getting seemingly normal function from the 02s? If they are 0, or very high, then you might actually have an issue with the sensor. 650ish would be pretty normal. Its a heater circuit code, so its possible the sensor function is actually correct, but the heater circuit is operating at a resistance outside what the circuit is expecting. Sometimes 3rd party 02 sensors can have that happen.
Are you using stock sensors, or the Bosch ones most harness makers use?
