ABS light on instrument panel

Yes - Something IS wrong. The base (stock) tune in your PCM does not "see" your truck properly. Unless Bill wrote a new "stock" tune for you, I cannot see how his "tune" files would have anything to do with this.

How did you get your truck to run in the first place after the engine swap before Bill entered the picture? I may be wrong,. but I'd guess that someone "flashed" a stock tune into that PCM that made it work with the new engine. Then, Bill wrote custom tunes for that flash (hex code).

My "educated" guess is, the stock flash DID NOT include your ABS brakes. So, I'd bet you need a new stock flash. Once you get this, I suspect Bill will have to rewrite your tunes - similar to getting a dealer reflash.

If what I'm saying is plausible, go back to whoever did your stock flash and make him reflash it with the CORRECT stock tune. Make sure you set your truck back to stock first though!

Jack,
Bill, in fact, wrote the stock 5.4 tune on the orignal 4.6 ECM after the engine swap. I had to give him the #'s from the original ECM so he could figure out the what the 5.4 hex code was going to be. So, if the stock tune did not include the ABS then it needs to be done again. Can you forward this to Bill so he can review his original tune to see if it was correct?

Okey-Dokey - I'll try to draw his attention to it.

Jack, you yourself suggested in an earlier response that the stock flash did not include the ABS brakes in the tune. I want to make sure that Bill's tune included the ABS brakes before I start spending a lot of money trying to figure out something that may be as easy as checking a stock tune.

Today, I was on an empty street and decided to test the brakes and they locked up everytime I was firm with them. This is bad and is a serious issue in regards to safety.

Please get Bill's attention on this and if everything is good with his tune then I'll start spending money to get this resolved, but I am not spending money to get someone else to mess with my stock tune if that's the issue.

I'll leave a post on the mod board about the issue. For now just be careful until this gets ironed out.

After my two close calls, I am very careful.

OK guys, I've waited long enough to see if Bill's rewrite of the original stock tune included the ABS. I think it's ridiculous to have to wait this long, especially with a safety issue of my brakes locking up as much as they have. I need Bill to recheck his file and I shouldn't have to be put on the back burner any longer.
