When asking for technical help at the very least let us know the version of firmware you are running.Cliff's Calibration (Mapping) Guide is a MUST READ: http://www.vemssupport.com/forum/index.php/topic,97.0.html
Hello all,I am looking to wire a bigger cooling fan in to my vems instead of via the fan switch.New fan is 38amps, so will definitely need a relay, but what do I wire in to the vems ecu?Anyone got a handy diagram to help out.cheersscott
oh interesting....I only have 4 ignition outputs on my ECU board, and they are all in use.....v8 wasted spark....But I have managed to find a spare IRF640N driver in the kit that came with my ecu…..which should do.So its not going to be that straight forward.cheersscott
