I'm not at the shop anymore, but yes.. When I was using plain mode I could type atrv and get back voltage, 0105 for coolant temp, 0902 for vin, etc and it spit back the correct response.. When I had hex selected I had to type in hex equivalent of of ascii, like 39 32 for 0902.. in plain mode you typ...

I just downloaded and tried coolterm and it works fine with the first elm327 I grabbed, a bluetooth 38,400 baud unit claiming ELM 327 v1.5. Default settings used other than changing the com port and baud rate. EDITED!!!! Hold everything.. with coolterm... Click on the view button on the upper right,...

What program are you using for a terminal program?? There may be a setting that is off..

That looks like it's responding the same as the one I was working on.. I suspect you could bring it back to life if you tried programming the correct OS and calibrations to match the boot and eeprom just like the E38 ecm's. Do you have anything to read the flash? You could probably find the vin and ...

Just went thru this with an independent garage that put a used transmission into a 2016 Acadia. They had some remote flashing company come to them and they bricked it, making it even worse. This was disclosed to me AFTER I drove there and starting looking at it and told them this was not a simple re...

NP, It's ECU.BruteForcer.0.0.8.7z that you posed a while back. I'll reach out to some friends and see if anyone has a gm mdi I can test with. ok, I had forgotten I posted an .exe here.. you'll need to install a .net for the brute force to work.. I do not think you need it for the powerpcm program t...

sorry.. I meant the brute force tool.. Power PCM works for me with the gm mdi but I do know a lot of other devices do not work with it. Developer was great for putting it here, guessing he did what he needed with it and has not been here in quite awhile and I don't think there will be any compatibil...

Honestly not sure why your getting the error, usually I think that's because the .net library isn't installed. Did you build and compile it yourself off github? or did you get the .exe somewhere else? Did you build it on one computer and run it on another? If so build using the release version and u...

That's the key I come up with as well.. Do you know the year? Are you USA or AUS? I think I remember Tazzi stating some of the earlier E38's on his side of the pond using a different algo?? Other possibilities are tuner locked or eeprom corrupted?

I am sorry to say I that I fear I am unable to help. that bin is odd for me, only see 1 eeprom section, not 2 like I am used to seeing. Little bit of research shows me that the E77 is unlike the USA ecu's I'm somewhat used to. I saw someone had noted that the eeprom is a separate chip and not the fl...
