Gear indicator not showing

[s2klotus7]

I want to go back to my old problem.
I want to show the gear indicator. According to the Dash2 manual, there are two ways to make the gear indicator works. If you have a build in potentiometer (like some of the bike) in the transmission otherwise use the gear calculation and enter the gear ratio.
Oh well, I did this hundred times and I'm not doing good. What am I doing wrong?

Below is the gear calculation I entered to the dash2 table.
I entered the final gear ratio and the tire circumference (by meter).


Below is what the dash2 generated value


Appreciate any help and thank you.

You have speed and rpm set up as well? You need wheel speed, not gps (IIRC).

Both read properly on the dash?

Hello,

Final drive is very low.

The numbers say that your car is capable of doing between 74 to 90KPH/1000 RPM in 4th. So... 80KPHish * 7 (1000's RPM) = 560KPH What car is this!

Kind regards,
K

The car is a Westfield 7 (lotus 7 replica) powered by Honda (01) S2000 supercharged. It revs up to 9000 rpm.

I'm using Honda transmission (6 speed). I don't have a wheel speed sensor except the stock Honda build in VSS at the transmission.

My speedo are calculated using the dash2 calculated pulse (this works).

If my final drive ratio is small & wrong, what value should it be?
I used 1.16 final drive (4th gear) 1 to 1.

Kindly go to this site: http://www.turnzero.com/technical_resou ... calculator
There is a dropdown and click Honda s2000 00-03. Change the tire size to
205x50x15 and change the axle ratio to 3.92 (instead of the honda 4:10)

I used the value to enter to my dash2.

Final drive is the diff ratio. Normally around 1:3x to 1:4x-ish. Put the 3x or 4x number in that box.

You need to have wheel speed fed from a hall effect sensor (or converted from a VSS sensor) into Conn-1, pin #8. The rolling circumference of the wheel needs to be entered and the RPM needs to read accurately.
