I have just in the process to make a few more Vems ecu for Impreza´s, and i have just notised that there is no 5volt supply from the oe ecu seperate to the mapsensor,
there is only one 5v supply from the ecu, and that goes to both TPS and MAPsensor,and that is probbely why i always had mapsensor problemswith the vems ecu,
Can i make just one , 1amp supply, and use that instead of the weak 100mamp that is installed on the vems ?
thanks,
Skassa
