[Spen221]

Hiya guys and gals, nice to see a uk site, I have just brought myself a Bmw 520i se Auto (2l) Anybody put hho on one? I know how to make the generator and a few other bits and bobs, was wondering how to fool the ecu, has anyone got info into whether its best to fool the map sensor maf sensor or 02 sensor? Also any ideas whether the 5 series 6cyl 2litre uses stepped voltage or wavefroms? Any help apprieciated, the cars a 98 if that helps, thanks in advance I hope :-D

Would a 5 series BMW have an ECU? possibly a limited one The On Board Diagnostic 2 (OBD2) did not become law in Ireland till 2001 for petrol and 2003/4 for diesel. I was thinking of installing a HHO on a 5 series 1998 BMW myself.
