After a lot of fiddling with the cable (junk!) I finally got the idle with A/C on down by 50 rpm. The adjust range is limited to -50 to +150 which sucks but the -50 is welcomed

I wish I would have bought a real ICOM unit when they were available for about $500 (I think) There are a few available for $800 + which is over $1000 in my money and I just can't afford that at the moment. I'll probably play around with the cable to see if I can get it working better. I checked again for codes and there is none but my check engine light is still on which is freaking me out a bit! Can anyone verify that is normal for the CEL to be on until the drive cycle is completed. It was never on until I reset the readiness monitor instead of the adaptions.
OK, took it for another drive and light went out!
