    Hey LRT,Its a lot better than before! :)
    It idles a bit rough, but without any throttle which is awesome.
    I still need to give it a little throttle on ignition, so maybe a little more cranking air as you mentioned.
    The scanner rpm doesn't match the gauges, but i can calibrate the gauges later when I get the software.I had enough time to check the alternator is working correctly 14.4V output, and to see that my thermo fans are not triggering properly.
    What pin on the PCM outputs the signal to the relay? and is it 12v or GND trigger?
    The temp got to 102C before I turned it off. I'm also running 8qt of oil in there for run in, so i could really rev it past 2000, but so far so good.
    Cheers,
    Stu
