Default AC codes

I deleted my AC system as part of the progression to a track-only car. I now have codes P0530 and P0645. Is there any way to keep these from triggering the CEL?

I have HP Tuners, but I'm not sure how. The DTCs list does not show either code as SES Enabled, which I thought means that neither code is active, or do I need to change the error code to No Error Reported?

Ok, I think I've stumbled onto the solution. SES/service engine soon and MIL/malfunction indicator light can both be off and you'll still get codes depending on what the error code is set to.

That's true, and you also may want to run diagnostics while car is parked with engine idling. Seems some codes are more likely to appear BEFORE you turn the engine off........
