R400 Duratec speedo code help, please
Discussion
Hi all.
I've had my R400 Duratec for a couple of months or so now and loving it.
However, I wanted to check the accuracy of the speedo as it seemed to be over reading by 10% (I've since learned that 'they all do that, sir'...!).
So, armed with the code given to me by Caterham, I tried to reprogram the speedo via the trip button pressed in whilst turning on the ignition. This code for my setup (R400D, LSD, 13" wheels) was 041306.
I noticed that the code on my ANALOGUE speedo was nothing like this, so (and here's where I made my mistake) I changed it to the 041306 WITHOUT NOTING THE ORIGINAL NUMBER!). SO, pleased with myself, I pressed the trip button again only to find ANOTHER code setup with the correct 041306 code already in there!
So, (and sorry for 'wordy' explanation above) if there's anyone out there with a R400D with LSD and 13" wheels who doesn't mind checking, please can I ask if someone would supply me the 'other' code (ie not the 041306 one) - there was possibly a 3 and a 9 in it - I can't remember, though!!
I seem to remember that there was a "set DSP" and "set DPP" or something like this on the speedo mileage display when programming it. (as I mentioned, to get into the programming menu, press the trip button whilst turning on the ignition - don't change any numbers, though!) I'm not sure what the 'other' code is even for - my changing it did not affect the accuracy of the speedo or the mileage driven at all.
Or if anyone knows what this other code is actually for and if it's relevant, then I'd appreciate that info, too. Also which of the 'DSP' or 'DPP' (or whatever they are called) relates to the 041306 code now as I don't know which is which now...!!
Hope you can help.
Caterham have offered their help, but don't have another car in with my spec to check with atm.
Thanks in advance.

39751 on mine. At the SVA I was told it was the one of the most accurate they'd seen. Legally I believe it should be between +0 and +10% error. So, if it is 10%, then yours is on the higher end. The rear 13 inch wheels (with CR500s) are the same rolling diameter as the 15 inch.

Hi Jon,
I was thinking I should be able to help as my r500 is pretty much the same spec.
However i think after re reading your post that you probably have the analogue speedo, and not the stack set up I have in my r500.
Please let me know and if yours is the stack type dash, I will try the same on mine, but I think,our settings refer to the wheel size and not a code.
Cheers,
Nige.

Hi again.
Many thanks to both of you for helping.
DCL, can I ask what the 39751 code is - is it the set DSP or set DPP code (or whatever they're called if not these). Also, is your other code the 041306 number?
That does sound like it could be the one. I'll try it (if you can let me know which setting it refers to). Thanks for the info.
Nigel - yes, you're right, mine has the analogue dials not the stack. Thanks for posting, though. (oh, and I must add that your 'youtube' videos were a huge contributing factor to me buying a Caterham in the 1st place). Not sure whether to say a big thanks and , or to come and 'have a word' as you've played a big part in me now being £££-broke...!! (but happy broke).
If anyone else has any different codes, then it'd be great to have these to try.
Thanks again.
Jon

Glad you liked the YouTube videos too, and sorry they made you spend your money too!
However it not just you, I seem to have influenced lots of people who have bought Caterhams as a result of my YouTube videos, quite a few have even bought new R500's as a result too.
Hope you get your speedo settings sorted out too!
Thanks for checking everyone.
This seems to be getting more and more confusing.
Anyone know who makes the dials as I might have to have a chat with them.
Caterham were sure that I needed the 041306 code for my setup.
I am finding that my speedo is less than 10% over now - but still over, nevertheless.
Any more ideas?

OK. Finally got to the bottom of this.
There is another code, but it's *0000 - basically not used.
The code I had in there initially was 039558 - Tim at Caterham very kindly supplied this to me today.
This code made the speedo over read by 10%. Meaning not only the speed, but also the mileage would have been over, too.
I replaced it with the 041306 code a couple of weeks ago and this improved the accuracy, but it still over read.
Today I spoke to a really helpful guy at Caerbont who make the speedos and he suggested to increase the 041306 number by roughly the amount that the speedo over reads by. I tried increasing it to 043371 (ie + 5%) and this was absolutely spot on with 2 different GPS devices. So, as I wanted a bit of leeway, I adjusted it to 042545 (ie + 3%) and this means the speedo over reads by approx 2 mph which is just the right margin.
I realise that this is immensely boring for most of you, but if anyone is having problems with their speedo accuracy, then this method might help.
(btw, my settings above are for R400, LSD, tyre - 175/55/R13 F and 205/55/R13 R - with the CR500's on - in case this helps anyone.)
Thanks again to all who helped.

Might see you there.

I know this is an old thread but just wanted to say thanks for helping me sort my speedo out. I too was told to enter 041306 but mine was still reading 15% above what it should. After reading this thread, I added 15% to 041306 and it's perfect now! If anyone is having speedo accuracy problems this really works!There is another code, but it's *0000 - basically not used.

Hi Gregs.
I must be honest that as it was a couple of years ago I have forgotten how to do this, but looking at Caerbont's website, I think that this link is the programming guide (if yours is the latest version with the digital display of mileage, not the analogue version) - http://www.caigauge.com/page28.html (the 'programming button' referred to is the trip reset button).
I seem to remember that when you get the digits flashing, it was simple to do. If you make a mistake with the digits, then just turn off the ignition and start again.
Good luck with it.....!
Cheers.
