chip, i've taken the output from the tewb unit and read it into excel using some vba code. the various values are then displayed as graphs, configured to look like gauges. i've also included the output from a 4 channel thermocouple reader that is connected to thermocouples in each exhaust port to measure egt. have a look at this, and tell me what you think:



this is a slightly old version, the newer one has scaling on each gauge, but it's on another pc.
