Just a quickie-fitted a new rear sensor (arm snapped)-ride heights have also been a bit iffy over the last year. Got the RSW eas software running -measured stored values for standard height-

100 100 105 105

I then used the heights function to get sensor heights and used my measuring tape and the up/down buttons to set all measurements to 470mm.

re-read sensor heights and they were

90 100 119 95

Do i just write these values into the calibrate section?

Yes

Oh and ideally there shouldn't be more than 5 bit difference across axles, otherwise it'll never settle.

Split the diff with 3 or 4 diff in the middle (across axles) and write them. then you can remeasure and decide on a tweek or not.

See how it acts.

You should calibrate all 3 heights, I use a measuring stick, adjust to the correct height +/- 5mm then write the figure back in the calibrate section for each level.

Thanks all-will give it a go. Will calibrate all heights-I'll make a measuring stick-I've also made a set of blocks out of hardwood-but stick seems a bit easier.

Many thanks again

A stick is indeed easier and quicker. I have a piece of alloy channel that stands on the ground with the wheel centre marked and from there the three calibration heights marked. I use the "Heights tab" to adjust the 4 corners and then write down the bit counts to be written back in the "Calibration tab" a few up and down movements to check if all is OK and tweak as needed.

The back readings are 119 and 95- is it best to average these and see what happens?

As I said split it with a 3-4 count and check. all around.
A change in the front will change the back, so need it stable then tweak.

That's a big difference across the axle, I would want to know why. Maybe there is some movement of the sensor on it's mounting bolts. Don't forget, the actual measured height can be +/- 5mm so with the bit count closer, a small difference in measured height across the axle is not a problem.

Thanks all-will have a tweak and report back.

Update-got the standard height correct using Datateks measuring stick method (excellent thanks). Only thing I found was that whilst the front finally stored bits were close to the measured values using the get heights in the software, the rears were a bit different. Other heights next.
Thanks for the advice again,
Regards
Steve
