When asking for technical help at the very least let us know the version of firmware you are running.Cliff's Calibration (Mapping) Guide is a MUST READ: http://www.vemssupport.com/forum/index.php/topic,97.0.html
After updating the firmware with UploadFirmware.bat found in "round_2009-03-03" the gauge does not show the internal temp. Hitting the button on the gauge 4x and nothing happens, then start to cycle as it should with the Egt, afr, analog input, rpm values...then 4x again and nothing...
where is this new update? The latest version i can find is from december 2008.
