Speed Source Setup, 350Z, Link G4X PnP

Hi,

I'm having trouble setting up SPEED SOURCE, so that I can Log accurate MPH numbers. 

So far, I've used CAN Freq 1,2,3 & 4, but speed readings are about 50-60% to fast, when I'm driving 40mph, logs says 60-65mph.

I've change the calibrations from 0-4000 with No affect..... 

What am I doing Wrong?

Thank You,

Tim

Chassis and Body -> Speed Sources. Set LF Wheel Speed to CAN Freq 1, RF to CAN Freq 2, LR to CAN Freq 3 and RR to CAN Freq 4.

A calibration of 0 or 360 will show the wheel speed runtime as the same value as the CAN Freq value, a calibration value of 540 should correct for a reading that's 50% too fast (75kph would become 50kph).

As a side note the difference you have is about the difference between kph and mph, what runtime value are you looking at in the logs and what units does it show?

Vaughan,

I was just looking at my log, It says HZ.....

If you are correct, where do I change from kph to mph?

Thanks so much,

Tim

In Options, Units it's set to MPH, but yet in the Log, say Hz

You're logging the CAN Freq values aren't you, you need to be logging the LF, LR, RF and RR Wheel Speed values.

I'm Blind, got it!
