This one is about 50 years old and is Colortune 2 but seems to be 14mm diameter. Any use?

Hello all, Doesn't time fly at this time of year! Wednesday 3rd July is our next monthly get together at the Wilton from 19:30 in the conservatory. If you haven't been before, we are a friendly bunch and the food is good also. I will remind you that the next car show is this Sunday 30th June at the Manchester Airport Runway Visitor Park WA15 8XQ. It is held on behalf of the Rotary Club and will cost only £6 per person as a donation to the charity. We hope to have a few Caterhams there and we will be in the ideal spot to also look at the comings and goings of the many flights. You can also visit the Concorde which has regular tours. Many thanks Iain McCallum lads@caterhamlotus7.club

Hello all, It is that time again to remind you that it is our regular monthly meeting at the Wilton on Wednesday 5th June from 19:30 in the conservatory. We hope you can join us this month. As per Paul's note a little earlier today, this message is coming to you from the new web based system that the club is migrating to. Please forgive this duplication but we have to ensure that all of the processes that we used to use have been carried over to the new way of communication. I realise that, because you receive this email, you won't have to follow the attached instructions, but i am sending this as a test for the future. Many thanks Iain LADS Following process.docx

Forgot to mention it is a Roadsport 150.

No idea if the attached helps, but it is from my 2010/2011 fixed cam Sigma build

A long time ago, but this is how i connected mine up: Car Caterham RoadSport SV 150BHP (1.6 Ford Sigma) with a standard Caterham fitted Caerbont Automotive Tachometer Connections Red in the DRE to Green Green in the DRE to White with Black tracer Blue in the DRE to Black All the connections are in the multi-plug behind the tachometer Set the DRE to 4 CYLs but with Stall not activated

I use the lead purchased from SBD and the free Easimap software https://sbdmotorsport.co.uk/product/mbe-map-kit-3-can-basic-can-mapping-kit-for-mbe-can-based-ecus The lead is VERY expensive now but there will probably someone local to you who has one you can borrow.

I have a Sigma 150 and recently had cause to replace the radiator for a Radtec and larger fan. I haven't really noticed the symptoms you are getting with the temperature variance on your 140, but with the new larger rad the gauge temp dropped from 80 to 70. However when I look at the temps via the ECU (Easimap) I see that the actual running temp is 80 (when gauge says 70) and the fan kicks in at 101 (when gauge is 90). No mods done to the ECU or senders so everything standard. Might be worth using Easimap to calm everything down! Iain

What does Easimap say the revs are? That is the 'normal' way we compare readings.

I couldn't find any torque figures when i did mine, so just did them tight! It is a non-stressed part so no issues.
