View of the screen while my Jeep was still warming up in "open loop". It drops to about 1.8lt/hr after a few minutes.



Cheers,

OK, so i went to fuel up today. Petrol is cheap at the moment in Australia. About 90c a litre. I had driven nearly 500k's and had to put in about 88lt in my 125lt tank.
When i went into the MPGuino Color touch config, its been setup with a wizard that asks you how much you actually put in. It then compares the new lt/100 with the previous number, makes the calculation and recalibrates the injector microsec/lt for you.

Very impressive! I drove away from the garage with my gauge all set for me and no calculations and config setups necessary.

I am currently running at about 18.2lt/100, so now its time to start working on a few ideas i have to bring this number down.

Overall, very impressed with the MPGuino Colour Touch!!

Cheers,

Just to recap, i fitted a touch screen MPG gauge to my OBD1 XJ 4.0. Wired through the injectors and speedo. After calibration it is very accurate and can give me instant and avg lt/100, distance to empty etc..

After getting base readings of avg combined 18.2 lt/100 and an 80kph reading of 14.5lt/100 a few weeks ago, it was time to do some work on the Jeep to improve things.

This included swapping out the ZJ clutch fan to a Hayden XJ clutch fan. New O2 and MAP sensors. Pump tyres up to 40 PSI. New fuel filter. G70 friction modifier in diffs and Nulon E10 in engine. Reset computer.

After driving today, the computer is adapting well and bringing the economy back into check. At 80kph i now average around 12.5lt/100. This is a US 18.82MPG. Combined at the moment is averaging around 15.9lt/100 which is a US 14.79MPG.

Considering my XJ has a lot of mods and weighs a lot more, i think the figures are starting to become reasonable. A brand new unmodified 1998 XJ 4.0 Auto had an official government EPA rating of a combined 16MPG and 19MPG highway rating. https://www.fueleconomy.gov/feg/noframes/14742.shtml

I'm not far off those figures now. A steady foot helps alot. Also, my transmission has the power/economy button. Economy locks the torque converter up at 45/50 kph (power setting is about 70kph), so that driving around town, i notice it uses a lot less fuel.

All these results are due to the new MPGuino Touch Screen. Its given me the ability to easily see fuel economy on my OBD1 Jeep at an instant.
Great tool so far!

Ah gee sorry to be the bearer of bad news, any MPGuino operates on the pulse signal of a fuel injector, focused around a regular petrol injection system.

Without access to a diesel myself to get waveforms of the injection signal, i wouldn't know if it'd work with any accuracy.

Sure are, three currently unmade but ready to assemble.

In other news, I'm working on an app to enable a Bluetooth version aimed at fuel injected adventure bikes. Its a long road to learn app development but its starting to take shape!

App is stable and works well. Bluetooth seems to be a good new feature!

Available for download, but only works with the device of course.

Check it out at
