Can you please try using the key $3C7B to unlock the controller? Include the $ sign when you enter the key.

I'm looking at them now, hopefully I'll have something for you to try soon.

The original PCM is dead. The second PCM appears to have a faulty lock. Is it possible the second PCM was tuned by another software package or another tuner that may have altered the lock - i.e. that may have locked the PCM?
Meanwhile, I'm trying to figure out some options to try to get past the lock.

We'll send you a replacement VIN license to cover the license for the original PCM. Please send your FlashScan serial and auth code as per the instructions on this page http://support.efilive.com/kb_article.php?ref=2143-YUOG-8049 to me ([email protected])

If that's not customer service, I don't know what is, and on a Saturday, no less. Kudos to the EFILive team :thumb:

I am pleased with this support and especially happy about getting the license back.

Life will be easier now that I have Internet in the house and don't need to walk down the street with my son's laptop looking for wifi :thumb:

Yes that is a possibility, the truck was crashed and history unknown.

Going out to try the new key. If it works and I can read the ECM should I full flash it or cal flash it?

Do I need to change the VIN? Do anything with VATS?

The new key didn't work but I got a 3rd ECM installed and have successfully read it :woott:

Going out to flash it after the batteries charge for a bit. Any tips on flashing a NEW ECM?

I successfully flashed my stock tune into the 3rd ECM; cranks but no start :mad:

Going back to update VIN but what is the VATS all about someone please?

Got the VAT relink done (twice) and downloaded the stock tune again successfully, but still no start. Must be another bad ECM :thumb:

try disabling the vats in the tune. I have done this before when it seemed like the vats relink did not work.

It runs and STRONG! I downloaded the DSP5 tune which started this whole deal and it started :woott:

No idea why the stock tune wouldn't run it as the DSP5 is built off that but whatever. It lights up the duallies at will on drive pavement :coolspot:

I have had a hell of a week with technology; router, internet, cell phone, even my $%^&ing voltmeter sh!t the bed. Must have cut Bill Gates off in traffic :confused:

Awesome support from EFI Live, thanks for the help!
