Well EFILive V8 just bricked an LLY ECM I have here. This is my first time flashing an LLY with V8 and its not going well.
I have a customer here who bought tunes from another tuner. The tuner sent him the DSP5 file in a .ctz format, "semi-locked" (unable to be modified/viewed in V7).
So I figured it would be straight forward to flash it. I click full flash (in V8) and it says "FULL FLASHING FOR E60/LLY CONTROLLERS NOT SUPPORTED". Ok right. Ive been full flashing LLY controllers with EFILive for 6 years, but I guess now its "not supported" all of a sudden.
So I download/update to the latest versions of V7 and V8, update the firmware in my V2, and reload the tune.
I click "full flash", and EFILive begins to unlock/secure the ECM for flashing. It did that for maybe 5 seconds then came up with an error message that said "controller locked with a custom key". I clicked OK, turned the key off, waited for the countdown... then I turned the key ON and the driver info center happened to say "AVG FUEL ECON: --.-"
I knew things were bad when I saw that the cluster apparently wasnt communicating with the ECM. Turned the key to crank, nothing. Dead.
Literally bricked the ECM. Tech 2 wont communicate with it, EFILive wont communicate with it. EFILive says nothing is there. Its as-if the ECM doesnt even exist.
HOW does this happen!!???? It hadnt even started flashing yet! All it did was attempt to unlock the ECM for 5 seconds and BAM. Fried. Awesome. Now I have to eat the $400 for a new ECM just so my customer can leave here with his truck today.
Just for grins, I got a spare LLY ECM off the shelf and threw it in the truck. Flashed it with TIS/Tech 2. Read the tune out with EFILive V7. Changed a couple things, reflashed it with V7, no problems at all. Flashes fine with V7. I opened up V8 and tried flashing it, and it gives me the same error messages, as if the ECM is locked, cant communicate, doesnt know what to do, etc...
Any ideas what is going on? Has anyone seen this before with an E60/LLY?
Is there any chance at recovering this ECM? Eating the cost of a core ECM just because of some tiny glitch in the V8/V7 confusing tuning/flashing combination is frustrating to me.
Im sorry if I come off like an ass with this post...its just that im kind of heated up about this. Im leaving for the Diesel Power Challenge tomorrow, and I promised this customer I could flash his truck before I left. I told him it would only take 10 minutes, and it ended up taking 2 hours of screwing around, a dead ECM, and he left with a stock truck.
