LBZ: Trip to dealer goes SOUTH!

[SIKDMAX]

The truck looks modded is part of the issue Im sure - triple gauges, lifted on 35s, SoCal switchplate, tint, exhaust, full stereo, etc.

Also something that didnt help was that the truck went in extremely dirty

I want to get the truck back, clean the engine bay up REAL good and then do a compression test and look over the motor. Then check coolant levels and oil sample and go from there. I think itll be time to do valve cover gaskets and some little stuff, but Im almost positive it wasnt HG.

They have already blocked his power train warranty

and your point?? i had a 8.1 that had motor problems they voided my warranty went to a different dealer to get a second look at were the regional rep just happened to be visisting and confronted him my motor got warrantyed no qusetions after that just start shit man dont back down an roll over kick some ass :thumb:

 

[Cougar281]

On the LBZ they can read the Tq on the TCM.
Now on what you posted For RPOs LLY and LBZ only: Calibration ID Numbers and Verification Numbers from the Vehicle Information screen.
The service tech is told to take a screen shot of the tech2 and Gm will tell the dealer of the last 10 calibrations it had also its just alittle harder to do then the newer truck.

I'd be interested in seeing the procedure to obtain that info from the LBZ ECM....

It wasnt a point I was making the others had not seen the vin check were GM already blocked his. Know how long ago was it when you confronted the Rep. Yes he has a case to fight but I would have the rep come to the dealership. Also I bet you confronted the rep a few years ago before the new Gm also it was a 8.1 not the diesel Gm is killer on not doing the warranty work on them for the smallest part if you piss the wrong one off you might end up without a warranty at all before your done or be fighting it for a very long time.

I will log into Gm and see if I can hunt it down and post it for you. Be later I have not been to bed since yesterday.

How does the TCM calculate torque input? I thought it just went off what the ECM told it.

 

[Cougar281]

I will log into Gm and see if I can hunt it down and post it for you. Be later I have not been to bed since yesterday.

Ouch!

Looking at what you just posted, the history they're referring to is the TIS2Web update history. They're looking for you to match the CVN's in the ECM to one of those in the TIS2Web history for each section. There's no mention of the programming history for the LBZ. Not trying to argue... Just pointing out how the GM docs read...:hug:

 

[twister773]

If what you said about it seeing the last 10 tunes? couldn't you just tune it to stock 10 times and that would cover that problem? It seems tough for me to argue anything without having looked at the truck before i took it in. The thing that bugged me is he kept saying heavily modified, then he told me how GM spent millions developing the motor and that it should stay that way, and that it had too much compression, etc...the only two things i thought that could really cause too much compression as far as tuning was boost and timing? If those were kept stock what else could cause it. When i told him heavily modified? It only has exhaust and thats when he told me well we already sent the word into GM and we are waiting to here back. Im supposed to get the truck back today or they said Monday. Im leaving for Canada Sunday and get back thursday so wont be able to get the truck until Friday if they don't finish it today.

 

[twister773]

And you guys really think they are gonna prorate a refund on the warranty...they will say something about small print and how i voided it and cant get a refund.

Nope... It only tracks the last 10 changes, and alternating back and forth between two stock cals would be suspicious (not to mention it can't be done with a Tech2 & TIS2Web)... It's a moot point anyway as from what I can tell, the cal tracking is not there in the LBZ ECM's near as I can tell (although technically, the hardware can support it, it's just not enabled).

Too much compression just doesn't make any sense..... IMO, they're blowing pink smoke up your a**.... It's a real crappy situation they've got you in. It sounds a lot like there's nothing really wrong with the motor, but they're trying to trump stuff up and get more money, and in thinking that your truck is "heavily modified", have voided your warranty in hopes that you'll bend over and pay them to do the work...

IMO, just because someone has "triple gauges, lifted on 35s, SoCal switchplate, tint, exhaust, full stereo, etc." does not mean they've touched the motor... Not saying weather or not twister has tuned it, but I've seen many a truck with all of the above (except maybe the socal switchplate) but bone stock motor. Heck, the triple gauges most of us have are gauges the truck should have from the factory.

 

[twister773]

My truck has keys, isnt lifted, on 33s'. Has a boost gauge and pyro gauge. and the socal switch mount is for strobes in the truck...has nothing to do with engine.

What is the screen that is shown on the Tech 2 in Henry's last post? It looks like a list of Cal IDs and verification numbers from an 05 LLY.

 

[RENODMAX]

Can they do that same procedure for LB7s?

 

[Cougar281]

What is the screen that is shown on the Tech 2 in Henry's last post? It looks like a list of Cal IDs and verification numbers from an 05 LLY.

It is, but it's the CAL ID's for the different segments (Operating System, Engine Operation, Engine, Fuel System, System, Speedometer, Boot Block & CPU). I verified that on my ECM. Each of those ID's & CVN's will match up with one of the segments.

 

[Mike L.]

I'd be interested in seeing the procedure to obtain that info from the LBZ ECM....

There was a big write up in Transmission Digest how to do it with a Tech 2.

 

[twister773]

Mike im gonna have to post pone my trip down to you for a little bit :mikelsheep:

It's hard to tell since the picture is cut off, but it looks like it says Engine before each Cal ID.

 

[Cougar281]

Correct. It does. That's referring to the engine controller.... If you look at the same screen for the TCM, there are two Trans lines. One for the OS and one for the CAL. I've gone down the list on my ECM and each one does match one of the segments from TIS2Web.

 

[ripmf666]

There going to look to see if the verifiction number comes back to that truck in it history with updated from Gm. If the dealer has no record of changing the cal I'd that's were they have you with nothing should be changed other then thru the dealer network.
