Dash2 speeds
Posted: Mon Sep 27, 2010 3:49 pm
I have a Dash 2 and DL1.
Dash2 firmware is 9 1 9
A Cheery speed sensor wired into the Dash2 for road speeds.
Symptom:
above ~99 mph, the speed readout goes flaky then to 0. It returns to normal when the speeds drop below 99 again.
I worked perfectly a month ago.
I did change the brake cooling ducts to which the speed sensor is mounted on. I didn't measure the gap from the sensor to the bolt head, but it was visually the same.
The oddball thing is that the speed sensor data is perfect when logged on the DL1 and viewed in analysis.
Any suggestions as to why it's flaking out on the Dash2? Are they super sensitive to air gap?
It's one pulse per rev with about a 2 meter circumference wheel (245/40/17) at it seams to happen around 20-23 hz or so, which is well inside the capability of the dash and the speed sensor.
From the other thread, I think I'm having GPS issues too, so couldn't switch to a GPS feed on the Dash2....
