It has been done and I have the program.
I need to look at the LS1 program closer and I have contacted a company for some help.
As we all know the 4T80E is a FWD trans and the LS1 is a RWD car. Also I need to look at the way data is transferred between the PCM and the ABS. The other module should be ok, but the PCM ABS has multiple data lines.
I must be missing the boat here, but what will a LS1 pcm do for our northstars besides give us fuel and spark maps that weren't designed for our motor?:hmm:
I have a few small bugs. I got the rest of the piggyback harness done. I am running two PCM's. I push out a pin in the jumper and had no charging system. I just fixed it. It is insane fast. BTW 158 top speed.:hmm: I was under the impression it was 200+.
My VSS signal is messed up so 35 mph = 158 in the Shelby PCM, but the stock PCM shifts at the correct speed. after hitting 158 it will cut out:histeric:
I have the schematics for the following
Sensor connector terminals
------------- A------------------B
99 Deville -- High (PPL 401)----- Low (YEL 400)
99 Seville -- Low (PPL 401)----- High (YEL 400) This is my car
99 Carmaro -Low (LTGRN/BLK 822)--- High (PPL/WHT 821)
99 Shelby -- Low (LTGRN/BLK 822)--- High (PPL/WHT 821)
I am going to swap the two wires at the Shelby PCM and see if it works
VERY INTERESTING!...What did you get to do with the ls1 pcm...get more timing?,better fuel mapping?....The video's look good...you could probably get into the 12's with that thing soon....
If you put a blower on that thing and youre in the 12's now..........You will need large drag radials to get any traction at all, and you WILL be in the elusive 11's.......
