2006 is going to be an E38 ECM I believe. The 2007 and 2008 models are E67. The C6 fan issue is mainly dealing with the 2008 model vehicles. A couple of the tuners have been able to activate...

08 XLR-V operating system is 12618588

I dont have a copy of it.

Thanks Andy for that hint. Maybe you aren't such a bad guy after all. hahaha :cheers:

Unfortunately, I don't have access to an XLRV to download its tune. Not sure if the typical XLRV owner...

You might see if JAY4SPEED can get you the wiring pinouts / diagrams for those ECMs. He has offered up similar TBSS diagrams on the TBSS forums.

Thanks Justin. Check your mail Erik.

Ross, would you mind sharing this file? I don't want to give up on getting this working.

Thank you Justin. I appreciate the help.

Ross, I truly do understand why you would not want to spend that much effort for this issue. But what about a segment swap from another vehicle with the same OS? Any help you can give would really...

As mentioned earlier in this thread, the 08 Impala SS has the same OS, so that may be the ticket. I just couldn't find an EFI file for an 08 ImpSS. I looked all over the normal repositories and...

I don't think HPT can change the 08 TBSS to efans either, can they?

Scarab - I burned up 3 Flexalite controllers with my SilveradoSS fans. It worked great normally, but I was paranoid waiting for...

Too bad for me then. :shock:

Ross, any chance you'd send me this file you mentioned earlier in this thread?

TTT.... still looking for a way to control electric fans on a 2008 Trailblazer SS. I know JAY4SPEED gave up and went with LS1 fans with relays, but I own a C6 fan setup with PWM controller that I'd...

Since its an 09 E67, I would not attempt to load it on anything except an 09 E67 ECM.

That is correct. He kept the 2009 OS on the 09 ECM, but changed the table values to match the settings from his 08 ECM. This first 'test' was to find out if he could make the 09 ECM / OS run his...

I had the same issue. Make sure you are running the 7.3 build 555 software. Then you need to upload the most recent firmware to the V2 box. After that, the PCM read will work properly (and do it...

Yes, Turbo595t, I had the exact same results and the same calculations. I had already calculated the stock 245.75.16 tires out to 411. When I saw 424, I thought that the speedo must have been high...

Great. Thank you Ross. I figured it was something like that since the LBZ software is still undergoing changes. I just wanted to double check.

Have a great day and thanks for an excellent...

I know this should be a simple change, but I need to make adjustments for larger tires on an 06 LBZ. Looking over the available options in the tune file, the only thing I can see at this point is...

I'll give that a shot. I had seen other posts referring to a firmware update, but didn't know exactly what it was. I'm sure that will take care of the issue. I'll respond back if I have further...

I just attempted to read a 2006 LBZ. I have the 7.3 build 555 software and a V2. The connection went fine, status verified as a LBZ and it began downloading the tune. When it finished, it...

Thats great!

I have flashscan logging the analog output from my LM1 wideband. I happened to notice the other day that the LCD readout wasn't the same value as I was seeing on the laptop. I know it changes...

My truck has a fuel pressure regulator on the rail. It takes a lot of guesswork out of injector tuning.

I figured you would be interested in the info. Doing my research, I stumbled on many of your posts from several different forums regarding this topic. I'd like to say thank you for digging up as much...

Thats the thing, you should get the offset information from a reliable source - either the manufacturer or from a trusted source with the proper testing equipment.
