Hi all,

so i've been messing around with a spare me7.5 ecu for my 1.8t before i touched mine.

my ecu has come with a unknown map on it and can't be read by nefmoto so i bought a MMPS cable.

When reading my ecu is there anything to look out for? i heard somthing about them possibly going into valet mode? is that possible? thanks

There are not any risk reading an ecu (at least me7.5 or old ecus), mpps work very good on vag so not worry about it, if you brick the ecu writing you can recovery it using boot mode of mpps

If you're worried and it's a spare then maybe you should have a go at bootmode. It'll definitely read in bootmode, and one day you may need to do it so it might be best to learn how to do it when there's no pressure or time limit on it  Grin

learn to read and write the 95040 eeprom and to read and write the flash as it'll help in the future.

Except if it's running APR or another commercial tune that reverts back to stock load settings.

If you start with reading in boot mode - that won't happen.

Yes. The majority of useful maps will be encrypted anyway so not much use to you. If you want to tune, start with a proper ORI for your SW ver and go from there. Don't tweak other peoples calibrations.

Thanks for all the help guys.

I've successfully managed to rip my ecu And flash it onto another that original had a different software version and it runs exactly the same with no problem.

I'm quite excited and I was looking at vag EDC suite but I can't seam to find a getting started guide like winols.

Childish but the first thing I wanted to edit was hard cut limiter.

Cheers

EDC suite is for diesel ECUs. It'll not find much in your ME7
