Trying to do some idle tuning to get my 78 chevy Luv on the road (RWD 4G63T). Has 1g harness with 6bolt motor with 880cc injectors on SD. But for some reason it some times idle fine and then few seconds later just idles like crap and stalls out. Does my ISC or TPS look like its crapping out? I am running a 1g TPS with Idle switch wire connected. Any ideas? Also I have not set the timing yet to 5 deg since it keeps stalling.

If you have injector voltage offsets and coolant offsets, check those also as they do effect the tune. I usually take a picture of the settings then just fiddle with them and if I goof it up, I just reset it to what it was and move on, LOL. Sitting in the car running and having your changes take effect immediately usually gets me close if I don't have tried and true settings from the manufacturer of the injectors. Get that base idle set to 5* also, very important. I usually set the very first timing table box to 5* in my tune, to get started.
 
here is another log. Idled at least now but high rpm. Going into closed and open loop. why?

For some reason battery not charging. New 90amp alt and I think I have it wired correctly.
Anyone know how to wire an alternator correctly on a non-dsm truck with dsm 1g harness? I dont have the oem gauge cluster.
