I have acquired a clamp on sensor that used to indicate if there is a fuel pulse in the injector line. I'm going to see if I can use it with my MPGuino to get an estimate for fuel consumption. The clamps themselves are not cheap( around $200 American new) but might be found on Ebay in the test kits that I got mine in. It was in a Mac Tools tester that indicates pulse and one version also generates an RPM reading. I'm wondering if I can also use this for the rpm gauge signal. Might not work at all, but as I have all the parts, why not.
