HPTuners write to PCM

Hi Guys
I have always used the CAL write but I have deleted a DTC. My Question: do I do a entire write or just a CAL write to set it?
thanks
Bill

always use the calibration only rewrite... the only time to use the full rewrite is if you're changing the operating system

Thanks - I did that and still getting the P0137. I looked at the file and the P0137 is unchecked.

What is the code set at?

MIL on 1st Error
MIL on 2nd error
No MIL light
No error reported

The first two will set an SES light, the third option can (and/or Service Vehicle light) if you have the SES Enable checked (no light if SES Enbaled is unchecked), while the last one will not. You can't just click off the SES Enable setting and turn off the code.
