It has been a while since we have "officially" supported the M42 engine, but it is time we bring that support back. Watch our site for your ECU type to appear on our WAR Chip list. Currently the e30 "175 ECU" is supported and the e36 "990 ECU" will be next.
The Miller Performance WAR Chip forum is a great place to look for help for your MAF or WAR Chip, share tunes and show off your setup. WAR FORUM.
