Re: old tech
the fault code system on the 155 is stioll a bit limited, especially the 8v and V6. They use the motronic M1.7 ecu...
Anyway, I would like to ask you a question if it's no bother... I need to know what the RPM signal to the revcounter looks like (voltage, number of spikes per revolution etc)... Doesn't matter which engine or ecu, I already know they work in the same way....
I need this info to know where to hook up the tacho on the aftermarket ecu after the rebuild...
