Summary of change:
Hi everybody, I am looking for a configuration for 3B engine or for the change that must be performed on the configuration attached below. What are the precise modifications for the conversion from motronic55 v3 vems from Audi ADU, ABY or AAN engine to 3B Audi engine. I suppose this is only the ignition output that shall be only one channel rather than 5 channels for the ADU, ABY and AAN engine ? Many thanks in advance. All the best. * actually, the engine is almost the same but the '''harness differs''' (and the number of ign transformers of course) * the 3B and AAN harness has several annoying differences (even where they should really be identical, like trigger inputs) * if you kept the 3B harness, just want distributerless ignition with 3 channels (1, 2-5, 3-4 wasted spark) or 5 ignchannels, you don't need to "convert", just use the pins on the extra EC10 conn (or SSC6 in older models). * you can find some related pinouts in http://vems.hu/download/v3/Motronic55/Audi/ , although useful for verification , it's not suitable for building or rebuilding a device * if you really swapped harness from 3B to AAN, maybe it's best to sell the 3B ECU and purchase an AAN type (or an econoseal ECU and a v3*harness).
