ECM Unlocking Service

[Sledhead]

Any recommendations for getting this done (A site Vendor)? It would be great if there was something in Canada but the lower 48 would be my second choice.

Bump for an unlocking service, some of our Vendors must do this?

As far as I'm aware the only way to unlock an ECM is to have the person who locked it unlock it.

I know a TECH II won't do it.

Thats right!

Check All Season, Fleece, SoCal, or a tuner that exchanges/sells them read of lots of guys who have 2 ECMs to change if one locks up etc. My tuner is only 10 miles away so I just have one.

EFI said they would do it for $50 AUS but shipping... I found a couple others online (PCMcalibrators included), just wanted to support the site vendors first.

I think they have software that just hits it with every $xxxx hex key combination.

If your tuner locked the ECM, it was for good reason, dont ya think? They dont want the particulars of their tunes shared openly.
If you then attempt to unlock the ECM by these other means, isnt that going against your "agreement" with your tuner?

Why cant (or wont) your tuner make the changes that you require?

I think it was a spare ECM he had from another motor or something.

There was no mention of that in any of the posts. If that was the case, then I am very sorry for my post.

I read it in another thread he had. No need to apologize. I agree with what you said.

No issue, the ECM came with my spare motor from a wrecked truck. I assumed it to be stock but when I needed it - locked. Strange, not sure who would have tuned and locked it in central B.C. about 6 years ago.

I don't care to see the tune, I'm working with Trent on a DSP5 tune just afraid to do any flashing till I get a spare again after all the problems I had a couple weeks ago.

Can you post the ECM serial number ???

I know several years ago Wester's was doing some Duramax tuning out of Canada somewhere. I'm not sure what they were using or if they were locking the ECM, but as I recall, it was pre-EFILive.

Westers garage could probably do it. Give Lyndon a call. I had to take my 05 ECM down there one time. Located in Tilley, Ab - small town out of Brooks.

You know, I did think about calling them on a long shot, maybe tomorrow.

You will also get it back re-flashed with a STOCK TUNE, whatever was on the ecm will be wiped out.

I lock my ecm's so the internet copy catter's don't steal my hard work and resell/whore it out for a quick buck.

There are over 65000 possible unlock codes as well so if you want to start guessing it will take a long, long time.

He uses a tuner that is very similiar if not the same as TUNERCAT II. I know his files are TUNERCAT II compatible that he now sells. It is more of a computer tech guys kind of programming from what i ahve seen as it isn't laid out in simple tables and such like EFILIVE. I do believe though Lyndon would probably be able to unlock it or write over it as he does his own coding and such for his software.

I checked in my ecm/customer spreadsheet and out of the hundreds of SN# of ecm's I have flashed/locked that isn't one of mine.

Are you sure it's actually locked and not just screwed up ???
