Not real happy with autometer

This thread's a month old now. Did you get your problems resolved?

I've had mixed luck with my Autometer gauges too. The first was with the fuel gauge while I was assembling the car. Had a new, stock empty tank and sender. Powered on, the gauge would read 1/4 full. I sent the gauge to them and they returned it working correctly. However they did mention this: Also, just for future "FYI", the gauges are calibrated to match a factory sender, which is very non-linear. 10 ohms = Full, 25 ohms = 1/2, 50 ohms = Empty, and 73 ohms = below Empty. Which this said, most after market, or reproduction senders are built linear which means that E & F will be correct, but everything in between will be skewed.

I interpret that to mean, you can trust the empty and full readings but nothing in between.

Also had issues with the electronic speedo, but just when starting the car. It goes through it's little boot/sef-test routine each time it's powered up. Sometimes it would work fine and other times it would just hang or lock up and not function. They gave me the ol, "I believe that it is becoming electrically locked up due to RF noise produced by the starter when cranking the engine" excuse. Turned out it had to do with whether the speedo was receiving power during cranking. I had it wired to provide full power while cranking. The solution (from Autometer) was to wire it so that no power was applied while cranking. Weird. And nothing about that was covered in the instructions either.

Last spring the speedo began randomly rebooting one day and then completely died when I parked the car. It has very few miles on. So now I have to pull it (which I'm not looking forward to doing) and send it in.
