Has anyone tried to read the Eeprom from the dynojet stack?

 

Hi Pete, I'm in the same boat as you were. Did you just remove the battery and replace it with a new one and it came back to life without loosing firmware? I have bought a secondhand dyno that's been sitting for a couple of years and I have no flashing lights on the stack. Hoping by some miracle I will have your luck as I purchased it for personal use and definitely cant afford to upgrade the stack. The fact its been sitting for two years is a concern. I did use it at the shop I purchased it from so it was working before they packed it away.

 

Just a bit of a follow up. I replaced the lithium battery and the orange LEDs started flashing straight away. I then had to press the reset button to get it to communicate and everything is working again. I measured the voltage of the old battery and it was absolutely flat 0.0v so it would appear the firmware/eprom is non volatile and all you need to do is put in a good battery.

 

Glad to hear battery change fixed it.mine is still working perfect,I even bought a extra stack just to have for a backup.

 

For those interested I have a fairly extensive library of stack parts, modules. and components for previous generation Dynojet dyno's using Dynoware EX (pre-Winpep 8), email jamie@fuelmotousa.com with anything you are looking for.
