is there a way to change the abs speed signal so it'll put out the correct pulse for a speedometer? Its going into a 1990 chevy truck. I'm also having trouble with the stall. I'm not real sure what all I need to do it is completely different than what the tuning book shows. I also have permeant codes that I have turned off but still show up only one shows up on a hand held reader. Is there any need to adjust over and under speed settings with a large cam. I can not get it to stop the idle hunting. any and all help is appreciated

My truck would hunt for idle when set idle speed was too low, if not already try bumping that up 50-100 rpm. are you referring to abs because abs light comes on when driving? Try changing tire size, may have wrong tire size in the tune.
