| Re: Tach The tach out from the M48 ECU is usually provided by use of Auxilary Output 1 or 2 (pins 13 or 34) but is programmed within the ecu setup. Check your ecu config file first, or mail it to me and i'll look for you. Obviously, if you are using an MSD, it also provides a 'tach out' signal. [img]/ubbthreads/images/graemlins/cool.gif[/img] |
