Tuning the LS2 in my Trailblazer SS - ECM and TCM?

[TBSS]

I have yet to get a tuning package for my Trailblazer SS.....perhaps because there are no packages out there yet?

Anyway, knowing nothing about EFILive, I have been plodding through the regular website and now the forums. After attempting to do some unsuccessful searches (the search feature will not allow three-letter terms like ECM, TCM, LS2.... ) I am now posting here.

What will I need to tune my Trailblazer SS? There is a company selling a mail-order tune for the Trailblazer SS which requires that you send in both the ECM and TCM from your vehicle. Will I be able to tune both of these modules with Flashscan V2 when it comes out?

How much will the package be to tune my TBSS?

As far as I know, the Trailblazer SS, which has essentially the same 6-liter engine that's in the Corvette and GTO, uses LS2 PCM. That being the case, you'll need V2. The 06 model trucks with 5.3 engines still use LS1 operating systems, so they can be tuned with V1.

I read somewhere that EFILive will be charging extra for the ability to tune both the ECM and TCM, versus just the ECM. Do EFILive employees visit this forum? It would be nice to get a for-sure answer directly from them.

EFILive employees not only visit this site, they also post, and are a constant source of useful information. I can't speak for them, but I can tell you from experience, that when all the dust clears, EFILive will be the best deal around.

Uh, thanks, but I'm just looking to have my question answered.

Patience, young Jedi. I was just trying to give you some insight until one of the EFILive guys can answer. (They're in Australia, where it is now almost 5:00 AM. I'm sure Ross will post an answer shortly.

Ross, are you there????????????????????

My understanding is that the ECM and TCM each require 1 pcm licence (since they are 2 separate controllers);
correct me if I'm wrong.

Split it up. Take the customer views as well as the research into consideration. Make vehicles with a TCM instead of use 2 licsenses, use 1, but that license is $150. You guys get alittle for your efforts and the customer isn't paying for two licenses. Just an idea.

[TBSS]

Which vehicles have this type of setup? Is it LS2 vehicles or CAN bus vehicles or what? What determines when the functions get split up - is there a rhyme or reason to it?

GM is moving this way with most V8 vehicles.
Probably comes down to computing power (or lack of) and having a standard TCM that can be configured for many platforms using the same trans.
