02 PCM 3 bar and RTT

[vanillagorilla]

I just put a 02 PCM in my 00 Sierra, and I was surprised to see that RTT isn't available for a 3 bar OS. When I had the 00 PCM RTT wasn't available for 3 bar either. I was under the impression the 02 PCM had more ram to accomadate RTT. Is this not so, or is there something else I need to do?

If its not supported its not supported. Theres really no possible way we could support rtt on 200+ operating systems, sorry.

Ok, I understand. I've been tuning this long without it, so it's not like I'm going to miss it.

Surely there is a pcm calibration that is supported for your truck. Does anyone know of one, and if so you can just flash that VIN into your pcm.

12212156 is one of the most popular 2002 operating systems & offers 3 bar & RTT. That os is used in 02 Camaro/Firebird, Silverado's, Sierra's and likely others.

How would I go about flashing the 12212156 into my PCM. Its a 411 PCM if that makes any difference. Is the 12212156 the OS number or the PCM number?

[Bill@HPTuners]

Thats the OS number, you'd either need to have a dealer/shop with a tech 2 flash you with the os or you could pull one off the repository & do so but obviously they are a use at your own risk type file.

Hmm...I'll look into this. I already applied the 3bar on this OS though so I could drive it. So you're telling me I need to blow 2 credits to run the 12212156 OS, 2 more credits for the 3bar OS and blow another 2 for RTT? Had I known that, I wouldn't have of just spent 4 credits to get the truck up and running with the 02 PCM/3 bar.
