Air Conditioning switch no longer works, megasquirt PNP?
Hey guys, I have another problem. My air conditioning compressor and secondary fan will not cut off! I have pulled the relay and of course that cuts the air conditioning compressor off, but i'm afraid that the culprit could be my megasquirt ecu. To understand the situation, my condensor runs constantly, even with the fan **** turn off and the a/c button off as well...
I heard that the A/C is ecu controlled; but doesn't the a/c switch itself toggle the power circuit to the condensor/fans?

Megasquirt PNP Spark timing maps...
I've been working on my fuel maps and I got the car to run a clean 11.5-12.2 air/fuel ratio throughout the rpm band at 12 psi. How does the stock spark timing map do, is it extremely conservative and is there any room for more power? I considered running megasquirt pnp closed loop/static timing at 14 degrees BTDC with 93 octane? Suggestions, any body got some good spark maps for a 12 psi 97' Miata?

Check the voltage at the AC button. It should be around 12 volts with the AC off and 0 with the AC on.
