    Problem fixed - the ECU wasn't sending enough pulses to the rev counter. Not quite sure why Caterham couldn't configure it correctly in the first place - they knew what combination of engine, ECU and instruments they were supplying. Yet more QC issues... In other news my IVA was canceled yesterday as the examiner has COVID :-(

    Thanks for explaining. The car is now going to Williams on Monday for them to investigate the ECU.

    So it turns out that the dip switches were set correctly, and swapping the rev counter for a known working one still gives half the expected reading. So it's pointing towards a sensor or ECU issue. Waiting for Caterham to phone me...

    Thinking about the dip switches a bit more, if the rev counter was configured for 1 Pulse Per Revolution, but was actually receiving 2 PPR from the engine, then wouldn't it read double the correct value? So in my case maybe it is set to 4 PPR (dip switches 10100001) and it is only receiving half the number of pulses that it is expecting. Will find out tomorrow!

    Very interesting thanks, will check the dip switches and report back tomorrow.

    Thank you, will try these things tomorrow. I have a multimeter and I know a bit about electronics, but I don't have a circuit diagram. The engine is running smoothly. The rev counter needle sweeps correctly from min to max and back when the ignition is switched on. All other electrics seem ok. The rev counter doesn't bounce - it just always reads about half of the expected value, which is why I hoped it might be a setting / mapping problem and therefore a quick fix.

    Hi all, I have just finished my 360R build, but when the engine was started for the first time, the rev counter was reading roughly half of what it should be reading across the rev range. Does anyone have any bright ideas please? My IVA is booked for Tuesday. There isn't time to take it to Caterham for the PBC as the final missing parts from the kit only arrived a few days ago. Eric at Millwood is in the process of checking the build for me, but if it ends up being a warranty job it will need to go to Caterham. Do you think it will pass the IVA? Many thanks, Rich
