StevehS3 Posted April 11, 2023 Share Posted April 11, 2023 #21 The metal strap is in the way to see the other number. I will take another look.#22 I will check the calibration at other RPM to get a better understanding. It may be that it is accurate higher in the range and the 6,500 to 7,600 area of interest :) Link to comment Share on other sites More sharing options...
StevehS3 Posted April 11, 2023 Share Posted April 11, 2023 The tacho is EET3-1B32-95B. Photos attached. Actually mine reads approx 180RPM with the engine off so that's some of the error found! Link to comment Share on other sites More sharing options...
John Vine Posted April 11, 2023 Share Posted April 11, 2023 #27 Many thanks. That'll help someone in the future, I'm sure. Interesting about the built-in error.JV Link to comment Share on other sites More sharing options...
StevehS3 Posted April 14, 2023 Share Posted April 14, 2023 I have taken this up with Caerbont. The upshot is that it would need raising with Caterham to get it looked into as the gauge is a proprietary part to their specification. They did say that it is CAN signal driven. Photo of Caterham Parts website. Perhaps I got a good one! Link to comment Share on other sites More sharing options...
