AEM A/F, Idle and Aircon questions
 

Hi All,
I am driving a 1992 MX5 1.6NA and I have 3 problems:
- I cannot get the aircon to run if I turn the fanspeed anything other than 1 from the cabin. If I have my fanspeed at 1, everything works fine, the compressor turns on/off as and when I press the a/c switch, if I put the fanspeed to 2,3 or 4, the aircon does not work at all
- I can get my car to idle cold or warm. The problem is after turning on the aircon, the car does not idle at all
- the aem a/f meter has a different reading from what I can see from the WARI, do I need to calibrate it?

I am running the latest version. Can you give me a pointer or two? Thanks all
