Leadership Team Shortshift Posted July 29, 2020 Leadership Team Share Posted July 29, 2020 Err... feel a bit silly asking this but I can't find the OBD port on my 2005 CSR 260... I've looked in all the obvious places and it isn't easily spotted; it certainly doesn't seem to be in the same location as on my 2012 S3 car.Can anyone tell me where to look? It's not the easiest or most comfortable of things twisting one's head upside down to see what lurks under the scuttle and dash areas.James Link to comment Share on other sites More sharing options...

Doctor Posted July 29, 2020 Share Posted July 29, 2020 My CSR had it at a weird position cable tied around the steering column - not an easy thing to spot. Link to comment Share on other sites More sharing options...

Leadership Team Shortshift Posted July 30, 2020 Author Leadership Team Share Posted July 30, 2020 Found it!It was, indeed, hidden away in a tight coil of wiring immediately above the steering column - not so different from Mark's car but rather more invisible. It was so tightly bound I had to cut away three cable ties and wind back some harness tape to free it up - but I now have it 'free' and just about able to access it.Job for the weekend (when it is a bit cooler) to connect up Easimap and see what's what. I'm particularly interested in the idle site mapping and TPS settings.Thanks all for the input and advice.James Link to comment Share on other sites More sharing options...
Ian B Posted July 31, 2020 Share Posted July 31, 2020 Sorry on further reflection I think mine was around there, but wasn't fùlly connnected, so we added one near the ecu. Will be interesting to see if you're able to get yours to work as it is. Link to comment Share on other sites More sharing options...
Leadership Team Shortshift Posted August 1, 2020 Author Leadership Team Share Posted August 1, 2020 Well, Ian - spot on...I connected up Easimap and nothing... Sure, there are four wires going into the OBD socket under the dash but there is no CAN connection from the ECU (so no data flow to allow Easimap functionality). I know this because I opened up the 36-way connector at the MBE ECU and there are no pins or wires in socket holes 8 and 9 - the low and high CAN outputs.Of course, SBD have a cable for this exact purpose but it costs a fair bit for what appears to be one female OBD socket on the end of a short cable that is terminated with two pins (one for each of locations 8 and 9). But - for the record - a few moments sleuthing confirmed that the ECU connector is a J2 type from Aptiv (formerly Delphi) and that you can buy pins for it (Delphi 12084912) for pennies. Ironically, the shipping cost is a bit more, but overall still cost effective.So it may take a few more days before I can start looking into Easimap, but at least it won't have cost much to add a compatible, working OBD socket.James Link to comment Share on other sites More sharing options...

Leadership Team Shortshift Posted August 2, 2020 Author Leadership Team Share Posted August 2, 2020 Well, to be confirmed (once the pins arrive and I knock-up a separate, Easimap-compatible under-bonnet OBD socket on a 12" flying lead).James Link to comment Share on other sites More sharing options...
MarkTheGoose Posted August 2, 2020 Share Posted August 2, 2020 Having read the articles in Low Flying and owning a similar car to yours, I'm now watching your endeavours with interest. I hope you ordered double the number of pins that you actually need Link to comment Share on other sites More sharing options...
Leadership Team Shortshift Posted August 2, 2020 Author Leadership Team Share Posted August 2, 2020 Ah - good point! I ordered six (at 40p each, or similar) with the shipping being £6!! So I should have bought twenty or so, if I had been thinking. But maybe your under-dash OBD connector will be wired and functinig for Easimap? As said before - no two cars the same...But yes, I need two pins for this job, would like to keep two for spares so I will have two that you can have, Mark. Be aware, though, that Easimap doesn't allow you to change mapping (because Caterham's ECUs are encrypted) but you can see what is happening with TPS, idle sites, lambda functionality, various (accurate) temperatures and so on, all in real time. A useful tool for diagnosing many problems and for setting up - particularly around idle and to make sure that full throttle means just that.James Link to comment Share on other sites More sharing options...
MarkTheGoose Posted August 2, 2020 Share Posted August 2, 2020 To be fair, right now, all I want is for mine to turn a wheel. OBD's are a fair way down my list of priorities Link to comment Share on other sites More sharing options...

aerobod - near CYYC Posted August 2, 2020 Share Posted August 2, 2020 For the MBE Delphi connector I found it was essential to use the correct crimping tool to get a sound connection - a 0.5mm open barrel crimping die ("B" type connector) with either a stepped jaw to crimp the wire and insulation at the same time, or separate crimping dies for wire and insulation crimps. It is preferable to use a ratcheting crimper, if available, to ensure the pin isn't over or under crimped. Link to comment Share on other sites More sharing options...
Mark w Posted August 2, 2020 Share Posted August 2, 2020 with the shipping being £6!! Obviously using something far superior to Royal Mail first class , maybe a white gloved butler carrying them on a silver tray ? Link to comment Share on other sites More sharing options...
Leadership Team Shortshift Posted August 2, 2020 Author Leadership Team Share Posted August 2, 2020 Not quite. From Germany... Link to comment Share on other sites More sharing options...
Mark w Posted August 2, 2020 Share Posted August 2, 2020 Still expensive , I had to send a 27KG WC to Germany last month and it only cost £12.30 by DPD air freight-48 hour guaranteed delivery ( Parcel Hero ) I dropped a bit of a clanger and bought the wrong thing , was pleasantly surprised how cheap it was to send it back given the size and weight .PS i can confirm that Villeroy and Boch sanitaryware is much cheaper from German outlets than it is in the UK . Now , back to OBD connectors .......... Link to comment Share on other sites More sharing options...
Leadership Team Shortshift Posted August 2, 2020 Author Leadership Team Share Posted August 2, 2020 Well yes, I know what you're saying, Mark. But I only needed two pins and buying six for just over £8 from this supplier in Germany worked out the cheapest (and possibly the fastest) way of getting them.I think you'll find there's a separate section somewhere on here for your specialist subject, called SanChat James Link to comment Share on other sites More sharing options...
MarkTheGoose Posted August 3, 2020 Share Posted August 3, 2020 I know it's way off topic, but today I've learnt that shipping a relatively large 27kg parcel to Germany in 48 hours can be done for £12.30. Every day's a school day! "Parcel Hero" noted for future European postage destinations... Link to comment Share on other sites More sharing options...
Leadership Team Shortshift Posted August 13, 2020 Author Leadership Team Share Posted August 13, 2020 All done - eBay special female OBD connector (from China), two pins for the MBE/Delphi connector (from Germany), labour as necessary (from Warwickshire) and Easimap functionality is now in place via an additional underbonnet OBD port. Encouragingly, all looks good on a first pass, including idle correctly set at Map Site 0.0.James Link to comment Share on other sites More sharing options...
David Knaresborough Posted August 26, 2020 Share Posted August 26, 2020 Hi James, Could you re-iterate how you connected the new OBDII port? I have the same thing (OBD device but nothing being read) and would be keen on adding this mod to be able to read any errors from the ECU Link to comment Share on other sites More sharing options...
Leadership Team Shortshift Posted August 27, 2020 Author Leadership Team Share Posted August 27, 2020 DavidIf you pull off the ECU multi-pin connector you will find (assuming your car is like mine) that Pins 8 and 9 are not connected. These are the two pins that need to be tapped to provide the Easimap feed through the OBD connector. The approach I took was to purchase a couple of pins and a cheap OBD connector (with 30cm or so of cable attached) and to connect the appropriate two wires from the OBD cable (pins 6 and 14 in the OBD connector for CAN Hi and Lo respectively) to Pins 8 and 9 within the ECU connector. The ECU pins for fitment to the car-side connector are Delphi 12084912 (female).Hope that helps.James Link to comment Share on other sites More sharing options...
