Hi everyone, i am new in the forum..

I am preparing an engine renault 1.9 dci from scratch (maybe to replace the old 1.9dt in my clio 97) and looking for ecu that can be easly modified. I found lot of info about edc15c2 (including pinouts, and etc). i saw some car brands that use edc15 or edc16 on same model.. What the difference between edc15 and edc16 ? is related to computing power? features?

Defferent ECU. Different map locations
