Ok thanks, i look into that. 360's me7romtool couldn't find/locate anything at all from my ecu binary. Tried some other rom files too and none of them worked (they were all r32, vw ecus). It did work perfectly on "ferrari 360 challenge" test rom that was available. Not sure why.
All the problem was with the search mask, it was too specific. Relaxing it by masking out registers, etc. makes it work across a much wider span of ecu's. Seems to be working on tonnes of models and firmwares these days, any that I try it on infact.
