it shows abt. every 10th of a second a different speed around the actual speed. the variance is smaller at lower speed but at abt. 120 kmh it is extreme from 60 to 130. I would like to have a stable info which varies according to actual speed only. I have this more or less since I changed from the Analog speedometer to the MXL2. The installation is as follows: Caterham CSR built 2005, The wheel speed sensor is the original one Schneider XS1N08NA340 (12-24V) on the rear right wheel. The signal from the sensor is connected to the MBE9A9 + of sensor to the 12V battery and - of the sensor to the chassis. Between + and the signal there is the original 1K 0.25W resistor.
I tried all the different settings in the AIM and MBE and made adjustments to the sensor position but no improvement.
Thank You for Your help
