Speedohealer v4 problems

Hey guys,

speedometer has been showing "0" and decided to try and re-calibrate the speedohealer tonight. no luck.

I came up with a calibration value of "-15.2". I have the 520 conversion with -1+2. If anybody wants to double check the math, that's fine too.

When I turn the ignition on, I get a quick “A” and then a steady “E” which stays on and won’t change no matter which button sequence I try until I turn off the ignition.

TEST mode works fine according to the directions. I am able to enter the TEST mode, and that seems to function properly. Blinking “ t “ when I spin the rear wheel. Then press “SEL” and the “ t “ goes away and the display goes blank. However, when I press either button after ending the TEST mode, the “E” comes back up and I cannot get rid of it until I turn the ignition OFF.

I have tried tried holding down both “SET” and “SEL” buttons waiting for the “L” so I can enter my calibration value, however the display always seems to end up on the “E”.

I contacted Speedohealer support, and the guy responded within about 5 minutes at 10p tonight. He's told me to disconnect the 2-pole TSM connector and try some WD40 on the port and the buttons.

Any additional help is appreciated.

Sounds like there may be an issue with where the speed sensor connects...I'm getting the impression the mph isn't been displayed above some rpm point, correct?

I just realized your unit might need to be grounded. I know some of the first v4's did and some didn't.
