CDL3 speed sensor to M130

[greenamex2]

Hi all

How do a pass a speed sensor connected to a CDL3 to an M130?

The M130 seems to expect a frequency value (in mHz...not sure if that really is MILLI or MEGA Hz!), how do I configure the CDL3 input to reflect that?

I am currently assuming I use "Wheel Rot Speed" as that is in Hz, and then use "Sensor Scale" as required.

Is that right?

You need to make sure the base resolution of the wheel speed is 0.1km/h in the dash when transmitted to the ECU.

You need to set the sample teeth to 100 and then the formula is the following to work out the scale:

0.1 / ( 0.1x 10 x wheel circumference in meters x 3.6 / 1000 ) x 100

for instance a wheel circumference of 2M will end up with a scale of 1388.888889

Thanks Nathan, I shall have a play tomorrow

As the limit for sample teeth is 10 I take it that you meant set "sensor teeth" to 100?

Other than that...all worked fine...thanks

Yes correct, sensor teeth.

Glad you have it all working.
