EBII A/C System
I still haven't got off my lazy ass since I did my T5 conversion and found a way to use the A/C with an EA computer.
For those of you that don't know, the EBII cuts the A/C compressor under WOT whereas the EA/EBI does not. When the EA ECU is in the car it runs perfectly, idles smoothly etc, but the A/C compressor won't engage! The car has the auto computer in it at the moment and isn't causing any problems, but because the auto ecu doesn't cut fuel when decelerating, the cackle that the exhaust makes is bloody embarassing! Not to mention that I can't get the ECU into self test mode. It still pings a little when in say 4th at 60k's and I floor it, it pings for a split second then stops. But if I back the timing off any further it loses so much power it's not funny. In this weather, I'd rather have a few niggly probs and lose a little performance than not have A/C!!
What I want to know is, is it possible to wire the climate control unit directly to the a/c clutch? I know this will cause problems at idle when the a/c cuts in, but I don't know any other way around it. I am trying desperately to get an ECU, but 4.0L 5spd ECU's are rarer than hens teeth out here, and I can't afford it at the moment.
I don't know if the EA ECU will go into self test mode, but I'm more concerned about the exhaust note and fuel consumption. It never pings unless I do it intentionally to see if it's still pinging. Any ideas guys?
