 EWS questions
When did EWS come in to play? I am looking for a couple e36 m42s with auto trans for some swaps into older cars....1970s and want to make sure I get engines/wiring without EWS. Do any of the 95 cars have ews? I know the switch to the m44 was right around then and understand the m44 is obdII and has EWS-II.
I have done this swap with the e30 m42 and a 5 speed trans but never with the auto and I think starting with an e36 engine and harness would be best to integrate the auto trans.
Do all pre 96 cars have the m42 or did some have the m44?
Mostly I can figure out the wiring on any OBDI non EWS car. I think dealing with the EWS and OBDII will be a PITA and would like to stay away from it. |
