OK Here is my problem.
The MPGUnio is great BUT as it takes it read out from the ECU side of the injector, it cannot see the changes I am working on.
I have a system that lets me control the injectors duty cycle.
Neither the MPGUnio nor the Scan gauge II can give me a real time readout of fuel used and MPG.
I have a fix for this IF I can get some help.
The old Zemco MPG Computer.
It uses a fuel flow meter system and its own speed/distance readout sensors.
BUT:
Most cars use a fuel return line.
So this system will gladly show me how much fuel flows though the system and right back to the tank.
So I think, use two flow meters, one in and one out.
Subtract the out flow count from the incoming count and you have the amount taken/used by the injectors.
The output needs to match the single flow meter’s system of a low count of negative going pulses.
I am so close to a real fuel saving system that controls the injectors but 100 miles test runs are hard to do.
I need a real time readout so I can see how much I can save and when I can either go farther or have gone too far and am hurting MPG with stumble and misfiring.
Can anyone help??
