ok......got it all hooked up the way that john suggested. all seems to work ok except for the fact that i have it set for a head of 1550 in normal, 1630 in idle up1 and like 1700 in Idle up 2........... this was just a starting point to get the bugs worked out....... when i tried it in normal it hit 1790 in normal and god knows what it was at in idle up 1......... it was screamin and way to twitchy for me to hang around in IU1 to tach it......... why is it so far off???? has anyone had this happen to them???? its got me stumped.
