1998 to 1999+ _PCM swap, TCS OFF after swap

1998 to 1999+ _PCM swap, TCS OFF after swap
Today, I converted my 1998 WS6 over to a 2002 pcm, one issue after the swap, the TCS OFF is always on.
Going through the pinouts by chipsbyal, it shows the UART data is not available in the 1999+ pcm, and just in the 1998 to drive the TCS system.
How do 1999+ cars work for the TCS? And can you swap in a 99+ TCS module, I really do not want to give up the TCS on this vehicle, I really do not want to swap back either, any help is appreciated.
Thanks,
Ryan

I ran into this exact same problem. On the EFILive Forum, another member and I had a long discussion about this. We just about ruled out all of the possibilities. I don't believe there is a way to get the 98 ASR/TCS system to work with the 99+ PCM. I believe the 99+ cars send the ASR/TCS information through the Class 2 Serial Data line. It's been awhile since the swap so I could be wrong about that. I have no idea if it's even possible to swap a 99+ ASR/TCS system into a 98 car, but it sounds like it's more work then it's worth. I will be keeping an eye on this thread but if you find out anymore information, let me know.

Cost is subjective, not many shops can do this swap, and not many can do the tuning, those that can will want to be payed for thier services

Does anybody know what data the TCS module needs to be sent over the UART bus?
I know the GTO guys are looking into a converter to convert the class-2 data to UART for some gauges, and if we knew what data was needed maybe a converter could be made. Maybe just running a 2004 GTO PIM could do the trick?

The link below has a good explanation. In EFILive, you can only swap segments between two tunes that have the same operating system.

Try PM'ing the HP tuners rep here on the forum, maybe he can help you with the segment swap.
If you can get the segment swapped, then all you need is the new PCM, and newer style PCM bracket.

EFI is a full emulator, all 500+ parameters displayed in the software can be changed in realtime.
HPT has limited adjustable parameters, and only a few at a time, depending on your choice selected.
EFI does require the use of the roadrunner pcm, not the stock unit.

Let's speak plainly:
EFI Live does not have real time tuning. It supports real time tuning of the $800 aftermarket PCM (roadrunner) that you replace your PCM with. You have access to every parameter in real time.
HPTuners gives you real time tuning of your OEM PCM. Also, since you get 8 credits up front with purchase, you can license you car, get RTT for it, and still have some credits left. So basically you buy HPT and spend nothing extra. It does not give you access to EVERY PCM parameter such as roadrunner, but it gives you access to all you need to get it tuned.

Its schemantics really, and an old arguement
One offers Complete real time tuning of every parameter in the PCM, but its expensive
One offers real time tuning for a select group of parameters, but costs alot less.
Which one is better? That depends on who is using it, and what thier needs are.
