Hi all,
I developed a fuel mileage gauge. It is supposed to be connected to diagnostic line.
Information is displayed on a 16x2 LCD display. There are two buttons MODE and SET.
It can be used on any JTD engine.
Information displayed:
A) Current trip information
- average speed
- average fuel
- time traveled
- distance
- fuel spent
B) Last trip information
same info as above, but for last trip
C)
- current fuel
- vehicle speed
- engine speed
D)
diagnostic information.
Later I will update this post with more details.
