GM Tech II
 

anyone have a Tech II?

im running OS 12605732 and would like the latest update 12614682. I do all the tuning on the car and dont feel like sitting in the Dealership parking lot transferring all the tables to the new OS.

Let me know how much ya want, money or beer. thanks!

I'm not sure I'm understanding the tuning part with the tech 2. Are you talking about. Idle learns bcm, sdm setups and the such?

He doesnt want to tune with the Tech II he just wants the newest updated OS from GM.

yeah,, reflash with Tech 2 with newest OS, then is read it with HPTuners and compare and makes changes.

Interesting. Hptuners dosent have a dashboard that will give you your data stream? You have a wideband? I wouldn't put a whole lot of faith in the narrow band o2's. Read your plugs

Honestly you probably wont see any changes. Most of the time with a new OS it fixes thing you can see with HPT or EFI. Every now and again a new OS will fix some errors in the timing or fuel or other tables. Unless there is a specific reason you just want that OS I wouldnt worry about it.

your missing what he is trying to do.

the update is to fix some battery drain issues im having..

How would that be caused by a tune or update?

GM :boohoo:

Yeah I was sure of that when the words tune and TT were in the same sentence lol

A battery drain issue. What year model car? Chased multiple drain issues with the newer 06-10 buicks gmcs. Most of those were bcm related

I agree on battery drain being a BCM issue. Hopefully, when doing an update with a Tech 2, only a specified module is updated instead of being a batch update all over the whole vehicle.

yeah, its a known BCM issue.
