That means graduated cylinder (both feed and return), super accurate fuel flow gauges comparing feed and return, or an MPguino or similar that measures fuel injector pulse width and frequency.

Alright, here is where you are starting to talk over my head, not because I can't understand but because I haven't learned it and the "why" of it yet. So, you are saying that a scangauge measures the same way the computer in the call measures therefore it's just as inaccurate so...what's the point, right? I'm guessing that an MPGuino is a home built system using an Arduino board? I'm liking this idea....seriously! That said, can my 2005 know and monitor the fuel flow feed and return or do I need to then splice the fuel lines and install a flow sensor?

Anyway good luck with testing! |
Thanks for the props, I'm all ears with this one! I really am... Any DIY hacks that I need to be aware of? I have a laptop!
Guys, I'm kinda rushing into it, I understand your skepticism. I'm a VERY methodical thinker and I REALLY, REALLY want to run these test before I modify. I want to do this the right way but I'm telling you, it's going to be two months until I can even think of buying anything more than $20 to test with so...I've got to think of my options. Why can't I monitor the fuel consumption along side of mileage on a large round trip route through the country and do this 3 times, then modify and do it all over again?
Or go ahead and modify and get an idea if it even seems viable based on my fuel usage and regular driving. Then, if it shows some improvements, go out and get that throttle body (will need it anyway either way) and locate the best testing equipment in the mean time and do some very calculated runs to come up with hard numbers in the rears? I know that this is ass backwards but I can't afford all the pretty toys today.
Thoughts?
