The thing that's kinda upsetting, is that we bought in on the beta software/hardware, with the promise of big time support in the near future.. That was a year ago.. and we still don't really have...

We finally gave up waiting for more support.. and went full standalone with our turbo trailblazer.. :(

Sounds like it's time to switch to a 4L80E... ;)

Oh.. I hear ya... I've blown out my fair share of transmission's... ;)

I just hope that we can get this nailed down.. I'm ready to see what kind of potential this engine has..

Travis

Oh.. I wasn't saying that.. I was saying that maybe we're over-reacting about tuning this ECU.. Since we haven't really gotten into it, yet.. maybe we're getting ahead of ourselves.

Travis

Yeah.. I am.. lol.. I just haven't gotten around to it yet. ;)

Here's the "almost finished" pics.. ;)

Yeah.. we'll have to figure out something.. Otherwise, we're dead in the water. :(

Do you have any ideas? Maybe we're being overly-worried too soon?

Travis

Yeah... it's wierd... it's like something is modulating the line pressure.. I'm not too familiar with the 4L60E or it's control systems, though. I assume that the CPU can control the line pressure? ...

So... is this something that we're going to be able to control? Without control over this feature, we're in deep doo-doo.. ;)

Also, I wanted to ask... will we have control over shift-firmness...

Ross, is the second CPU located within the PCM? Or, is it located in another box?

Travis

Well, that explains why I am having partial throttle/boost issues.. I get Reduced Power Mode if I'm cruising at 2500rpm or so, and get into boost at anything less than 1/2 throttle. However, I can...

Does TM affect throttle plate opening between shifts on Electronic TB equipped vehicles? The timing drop explains the "pop" that I'm getting between shifts.. but I was wondering about the throttle...

Hey..

Just making sure you guys haven't forgotten about us.. ;) I haven't recieved any emails back yet. I'm sure you guys are busy as hell.. just don't want to be left out. :)

Travis

Hey..

Yes, we are very interested in whatever you have to offer.. I've got many years of tuning experience with Electromotive, Haltech, FAST, etc.. We're trying to avoid going to that level with...

Hello..

We are finishing up our prototype turbocharged Trailblazer Project.. As it sits, now, we're relying on fuel pressure regulator, 550cc injectors, and a rising rate regulator (FMU). ...
