Spent a lot of time reading again and plan on playing with the adders over the weekend to see how to best attack the tuning.

I am considering just uploading Justin to my PCM. Unfortunately he would have to work at 1/4 speed to slow down enough to be compatible with my antiquated ClassII databus system though.

I would no longer be OLSD...i would be OLSJ

Back to me JUST for a second...I went and bought #4AWG battery wire and replaced the #8AWG wire going from the alternator to the battery block (red box). I didn't have time to test all the different points, wife was leaving and I have to watch the sick 3 yr old. BUT, I did hop in and start it up and test the junctions I have under the dash. Yesterday they had 12.8ish volts, they now have 14.3 volts. Again, not much time to put it to a real test of time and load, but that is sweet sweet news to me.

So....this wire....


is clogging up the works? hmmmm
I yanked that sob off a long time ago and seen more consistant voltage since doing so. I have a 4g and a 145amp alt. I see 13.8-14.4, 14.4 at start then about 13.8 at temp with the fans on.

Just got back from a drive with new 145Amp alternator. I also replaced the #4 with a #2 and took it directly to the positive terminal. It definitely idles better but I don't see a better voltage. As a matter fact, it is fuggin crazy. I am crazy rich, I fattened up all over the place for safety, until I get this worked out. I don't know what to check next. Here is a scan. The scan is with the truck running directly after the install. Look at the end when I go mid throttle and it just falls to 11 volts. what in the hell. The crazy burn out was me doing a U-turn and fish tailing it all the way up the highway. I need to make it shift sooner too.(frame 2512)

Save as the "dewey SDOL tx.txt" and change the extension to .cfg. I believe that's how you use the config setup.

Make sure to put the PID (ign volt) in the graph table with RPM so you can REALLY see how fubar'ed it is.

You think the battery is just weak? I did a test on it at Advanced Auto. It took a load. with out falling on it's face. It's about a year old, but I have come out to a dead battery many of a time.

Sounds like it's time for a new truck, easy way to solve idling issue.
