    Yes, any ignition-controlled live. The voltmeter will draw a small residual current when operating, so as Ben says if you leave it permanently connected across your battery you will flatten it (eventually, we're only talking milliamps here).

    Well any of us running EFI need to hook in a trickle charger unless its a daily driver because 3 weeks and the battery is as flat as a tack.

    Is that to maintain volatile memory in the ECU then Kym? That's terrible. Hopefully your ignition and fuel maps are non-volatile though; you wouldn't want to go into "limp home" mode every time you disconnected the battery

    Back in the 60's (E)FI was all about making power. Today's EFI is all about efficiency. Before re-mapping became commonplace the accepted upgrade for a modern EFI engine was to rip all the electronics out and stick a whacking great pair of carbs on!

    Works for me After all, life is complicated enough without worrying about your MAF...
