Now THAT is interesting. I have mailed setzi about the bug. He's been awol so... we're kinda boned i think.

So. Thats why proprietary software is bad. abandonware.

Phila: please help me complete me7sum Wink

For ME7.1, 0x08040 and 0x1B9B0 are the only ones left, right?

So I think the smoke happened after I tried to crank it (and did 3 times).

bummer.

When you went back to redo it, did you bench it or go boot mode through nef?  I would like to try and salvage that ecu of mine.

Also, can anyone confirm that my file above labled with winols was indeed corrected so i can double check myself?  i hate to admit it but thats the first time I have corrected checksums with winols, I dont like EVC and i try not to use their stuff but now i might have to use it as a failsafe.

Yes, AFAIK.

I do not have a clean sample pair of bins to test 1b9b0 though, so we'll have to come up with a set.

Also, can anyone confirm that my file above labled with winols was indeed corrected so i can double check myself?

Right now, it is impossible to really know anything. I *believe* the winols correct file is ok.

Oh one more thing!

Right now the MP block detection is NOT done by finger printing ASM, it looks for blocks that LOOK like MP descriptors. Now that we know MTX (might) corrupt the csum/inv pairs, I had to loosen the checking quite a bit.. which I don't much care for.

It would be better to detect the MP descriptors by ASM matching...

Also, I have several ME7.1 files that don't seem to have the 14224 block at all. I don't know if they are elsewhere, or really aren't there.

yo trooper, first of all, i had the exact same shit happen to me when i played with the the torque *_um map you messed with.
our fellow homey infinkc helped me out.  he tried boot-mode repairing my old ecu, but had no luck - i got the same clicking bullshit and it totally sucked.
if we ever find a solution to this, i'm quite excited to see what it is...

The file winols corrected looks good. I corrected your BAD file, and ran it against the one your winols corrected and they were exact matches. The bad one you uploaded showed one error before correcting that me7check missed.

I flashed the file on the bench with nefmoto (as that's what you did), then cycled the power and tried to connect with vcds. After which, I used galletto with bootmode to reflash.

Ok DD, sounds like it was good up until I tried to run the car on it then.  lessons learned for sure.  Thanks for the hands on testing and confirmations.

haha, yah?  dude, let's meet up then either for cars or beer then.  i'll pm you my info.  randomly enough, i'll get my LC-1 + ME7L fully operational this evening, so that'd be rad.  any chance you'll bring the matte beast?  assuming no since its far away, albeit portland is closer than say austin, texas.

No driving our WRX up, trip actually came about for some suby tuning.  Turned into a multi day drive trip instead of flying since the GFs family is up there.

Got your email, i will drop you a line with our sched.

Nye-no, and no. I'm looking into it though. I'd love to be able to finish it up, but my programming skills are sub par at this point.

Maybe less for contributing directly, more for building .exe files from the latest source..
