Ah didn't think about the checksums, take it the me7 checker won't correct it?

Be careful here! A big source of confusion is that there are two images on the ECU -- flash (motronic EFI program) and the eeprom (adaptations, immo, coding, etc)!

Well, technically, a third is the boot code, but let's not go there.

If you are just fliping the immo bits you only have to +1/-1 from the checksum, so thats easy, if you change other stuff in the eeprom then you need to fix the checksum. Luckily there is a checksum tool around for the eeprom too, or use 95040tool.

Ok, thanks for that, may just use the 95040 tool to save more work later on...

So I will start with a noob question here.....

I am getting ready to go open source type of stuff and step away from using Maestro.

I have a spare ecu.

I assume if I were to clone my immo data on my current ecu, and flash it to the new one (spare) and use the openly available HS file the immo should work fine?

Correct.

My next assumption is that IMMO2 cannot be adapted onto an IMMO3 ecu? Or am I getting these confused here?

Glad there is a place I can ask semi stupid questions because certain things do not absorb......LOL

Look in device manager under serial ports and see what your cable is identified as, like 'com1'. Not related to the physical USB port it's plugged into (although plugging in a different one may lead it to pick a different com port no)

Have you installed the vcp rosstech driver? Apparently that will work with a genuine lead.

thanks for the speedy reply i just revised the Use your vcds cables or what have you and i will definately be trying this tonight in doing so is there any risk to bricking my cable if i try and use vcds after reverting to vcp or should i just go vcp everytime i wish to use it as me7_950404.exe
again i really appreciate all the help and i am scraping by on alot of stuff i would not have been able to do without you nef gods!!

There shouldn't be a risk of bricking the rosstech lead of you're using the rosstech drivers, but I never managed to get them working myself (although others have). For the sake of $10 is personally just buy a blue kkl lead!

I have a all blue kkl lead its installed as a serial port but won't get recognized by either nef or vcds or me7. I also have another cable came with my galetto its a eobd cable nef acknowledges its there and when i moved the mouse cursor over the cable it says its a 232r chip but it won't initialize. I have successfully flashed with the ross tech via nef. I also ordered a new blue kkl cable with ftdi and 232r in the title. Its a lil frustrating to be honest Sad
