I finally got on the phone with Paul at Torqhead this afternoon to ask him some questions and primarily I was curious if he had been able to get the LS PCM he uses to fully integrate with the CCM that the Fleetwood uses. I wondered about it after seeing the info on his website about successfully getting the Corvette CCM fully integrated. Turns out he wasn't aware that the Fleetwood also utilized a separate CCM, but given the lower production numbers on those and that fewer people mod them I wasn't surprised. He asked me a few questions to see what I knew, and while my knowledge of that CCM is limited I did the best I could.
And so that brings me here with another of my weird questions: does anyone know for certain what functions are handled by the CCM that the LS PCM would need to cooperate with? I did a little digging and found a very old post from Bill that listed out the functions it handles according to the FSM, at the time someone was researching the possibility of adding the Fleetwood 4-channel ABS system to a B-body. Those functions are as follows:
Courtesy Lamp Control
Retained Accessory Power
Variable Effort Steering
Illuminated Entry
Delayed Interior Lamps
Daytime Running Lamps
Security System
Twilight Sentinel
I was under the impression that the CCM was somehow involved with the ABS and ASR systems, since to the best of my knowledge no one has yet put an LS PCM from any available source into a Fleetwood and been able to get the traction control to work. It's not a deal breaker for me, but until I'm able to do my rear axle swap and put in a limited slip unit, I would prefer to keep the traction control functional for when road conditions aren't optimal. And there may be others who would like to keep it working as well should they opt for an LS PCM upgrade.
And while I don't honestly know for sure if anyone on here has done an LS PCM into a Fleetwood, does anyone know of any other issues that may come up that could be specific to the D-body? I seem to recall someone having a problem with getting the AC compressor to turn on with an LS PCM, but I believe that had been resolved, although I can't remember if that was just on the D-body or if it was also the B-bodies. And maybe no one has yet put an LS PCM into a Fleetwood, since until Torqhead the only other way I know was with the EFI Connection system, and I don't know that many have put that onto a B-body, let alone the D-body.
Fortunately, Paul is outstanding and emailed me shortly after we spoke on the phone and he seems to believe that it may be a very simple problem to overcome, (if there even are any problems, for all I know his system may work perfectly fine as it is). However if needed, he said it would be a matter of some R&D time to come up with a revision to his PCM that would be specific to the D-body. At which point you would only need to order the version specific to the Fleetwood and his LS PCM conversion would still be a simple plug and play upgrade while keeping every stock function of the Caddy working.
