Injector leads and MPGuino
Hey everybody, I recently got this cool little device called an MPGuino thar calculates mpg using the vss and one injector lead. My problem is that our injector system is a grounding system, but the mpguino requires a 12v pulse. So is there anyway to get a 12v pulse out of a grounding system ? Thanks guys

Re: Injector leads and MPGuino
Thanks for that info, I have no idea how these things work lol. Basically the MPGuino requires 12v when ever one injector opens, and from what I've gather from other posts the ECM grounds the injectors rather than connects them to hot. So if I tap into the injector lead at the ECM will I still get a 12v pulse? Or will I simply be shorting to ground?
