Updating the Gauges

[Chris SSR400]

One of the (many) winter upgrades for this year was replacing my old gauges with the newer style 'R" gauges.

I discovered a few things on the way that I thought I'd share for anyone who so wishes to do the same.

Replacing the loom. Unfortunately I don't know the exact date of vehicles my loom goes back to, I have a 2014 car but it think its around 2008 but It could be much further back. I'd assume if you have a separate gauge loom connected (image of connector below) which can be found roughly behind the water temp gauge then this loom change should work...  

Initially I thought I was going to need to cut and splice the newer connectors into my loom as some have done on older cars but I discovered I could replace the whole gauge loom which made this a far easier job. For the 'R' style gauges I changed my existing loom with this https://caterhamparts.co.uk/gauges/5897-gauge-loom-seven-620-model.html (this wasn't in stock but if you connect the parts team they'll send one out, I think this might be the same for a lot of parts)

Once all the gauges were swapped over I had  3 tasks/challenges.

1.Calibrate the Tacho This is done via the dip switches found behind the grommet on the back of the gauge. This was straight forward once I knew how but I have attached the document Caerbont provided if anyone needs it.

2. Set up speedo: Millage & Pulse Code

How to set millage on new speedo (I can't remember where I found this so thought I share again.)

1. Press and hold the speedo button.

2. Turn on ignition and release button when ‘setup’ shows on odometer.

3. Press button again and ‘setodo’ will show.

4. Press and hold button until ‘000000’ shows then release.

5. Each digit will flash in turn starting with leftmost.

6. Press the button as each digit flashes to increase it by 1; do this multiple times to set the right number (remember to leave any preceding 0s).

7. When the digit is set, stop pressing the button and after a moment the next digit will flash, then repeat step 6.

8. Once all digits are set, all digits will flash; press the button once and ‘done’ will show.

9. The odometer is now set.

Set the wheel size pulse code which all the info can be found here: 

 

3, The fuel gauge: This one took the most time to find the equivalent calibrated gauge but in the new 'R' design. Some time around 2016 Caterham changed the fuel sender which read opposite to the previous one used.

My old fuel gauge was the following: EFCI-1152-78B (38D006A) which I replaced with FFC1-1B52-28B (Caterham no longer stock this part but it can be purchased direct from Caerbont)

Hope this helps if anyone else which to do such a vanity 'upgrade', personally im very happy with the outcome.

Chris.
