I've had the skyline a while now and I've been tuning the powerfc myself with fc edit/datalogit over the seasons to keep the AFRs where I want them. I've recently overhauled the fuelling as I wasn't using the throttle position vs injectors functionality. Supposedly a lot of amateur tuners will set the TPSvINJ to 1.0 and directly place values into the inj adjustments tab, which I believe is all you can do if you're using the commander. Anyhow, I've set up my throttle position curve and I've now been using the recalc base and have now got a much more accurate tune across the power band as I no longer have to add enrichment to areas that were once overly rich as the area would be touched when coming onto boost as well as cruising. Something I've never really got right though is the air conditioning! It's a right pain, my fuel map is perfect for what I want. I'm sitting at 14,7 on cruise and 14,3 at idle as my cams are 264s and don't seem to like sitting at stoichiometric. I come onto boost with AFRs of 12,5 and sit around 11,8 on max boost. The problem is if I'm just driving around normally at stoichiometric and then decide to turn air conditioning on, everything goes nuts! The AFR jumps to 15-16.. It seems calmer when in driving at steady throttle at high rpm, I,e, 100km/h / 62mph but still a lot leaner than I would like. So, with that said, and apologies for the wall of text above, can anyone help with the following: - 1. I've been led to believe that air conditioning is temporarily disabled when on boost, true or false 2. Is there any sensor value that I can use to determine when air conditioning is on and add enrichment to the mixture? I've looked at battery voltage, temperature, etc and just cannot seem to get it right. 3. Is this just a limitation of power fc and is the air con a problem for most people? Most tuned cars I see have had the air conditioning removed
