Eccles Posted June 12, 2009 Share Posted June 12, 2009 Haha!! 😬 I've picked it up and well to be honest......... ....... It's bl00dy brilliant!! *thumbup* Right from first touch of the throttle you could tell there was something different, it was an instant response. There were no coughs, splutters, or fuggieness, just smooth power delivery (and plenty of it!). I opened it up a few times (but not fully yet) and I was very impressed, and on the 90 mile journey home it didn't miss a beat and I averaged 42mpg (ok, ok, I know I need to learn to drive it properly to get it to a much more acceptable 30mpg 😬) I only had a quick look under the bonnet and yes the MAP sensor is now looking at fresh air, I will have to do some more testing over the weekend From my experience the only thing I can say is "What are you waiting for, get it done!!"

Windy Corner Posted June 12, 2009 Author Share Posted June 12, 2009 Thanks for the feedback, looks like I'll be calling Brett on Monday morning 😬 Thanks Ivan for being the guinea pig, anyone else had "the" upgrade ????

TobyCoulson Posted June 12, 2009 Share Posted June 12, 2009 No but I will be. I wonder how long it takes to get it done as I'm some way from Dartford and getting to and from by train is a nightmare so would rather sit around and wait if its only a couple of hours to upgrade Edited by - TobyCoulson on 13 Jun 2009 13:19:48 Link to comment Share on other sites More sharing options...
Rattie Posted June 13, 2009 Share Posted June 13, 2009 Awesome news Ivan! Hopefully this new configuration marks the start of great things for the 150 engine. Could you post a few pics of the new configuration? Martyn R300GRR specced and ordered for a winter build Link to comment Share on other sites More sharing options...
Eccles Posted June 13, 2009 Share Posted June 13, 2009 Hi Martyn I would take some pics but there is nothing new to see really. The only thing is that the MAP sensor is now disconnected and the pipe that was on it has got a screw put in the end of it. The rest of it must be in the black box.

Windy Corner Posted June 13, 2009 Author Share Posted June 13, 2009 Ivan, How much do you think it was the map and how much the refurbed throttle bodies ?? Was there much wrong with the TB's ??

Eccles Posted June 13, 2009 Share Posted June 13, 2009 Hi Rik Not sure really I didn't get to speak with anyone technical, they still look the same but the throttle feels lighter so they have done something to them. James Gibson said something about the problem being with the spindles, so what I'm guessing is that the spindles wore away at the holes, the holes then started leaking air which then messed up the settings for me. As this new map doesn't monitor airflow it isn't affected by this or any differences in air flow between the cylinders, although I'm sure that any significant leaks around the spindles would still cause mapping problems.

exfordy Posted June 13, 2009 Share Posted June 13, 2009 Mine has always been a little lumpy when cold but quickly improves as the engine warms. It's not perhaps as smooth as I thought it might be and seems to run out of puff at about 105mph. I've done over 8000 miles so can't be too unhappy! I know two people in Sussex - one whose Sigma 150 has been on the road for some time after mine and another whose is giving him awful running problems but is going to CC for supposed fixing. I should be meeting them soon and we might drive each others' cars to compare. I might be pleasantly surprised or not... Ivan, What's the basis for CC doing the latest fixes you describe? Only if a customer complains? They agree a car is running unsatisfactorily? They charge if the car is more than a year old?

Farreaster Posted June 14, 2009 Share Posted June 14, 2009 Glad its all sorted now Ivan. Regarding the refurbishment of the throttle bodies, how many miles has your car done ? Would have thought that wear in the throttle spindles would not have become significant until relatively high milages were reached - 30,000 plus. Or maybe an alignment problem creating sideloads - just guessing. Looking forward to getting mine done, going to try to persuade Caterham to send me an exchange ECU together with the appropriate "idiots guide" and I'll do it myself here Malcolm Link to comment Share on other sites More sharing options...
Eccles Posted June 14, 2009 Share Posted June 14, 2009 Hi Guys, Certainly I think it will only be if you complain or request it rather than a recall, not sure though if they will want to agree it's a problem before they will do it for free. With regards to the TB mods, I don't think that this is part of the upgrade but more to do with mine being duff. With regards to cost, when they found the problem CC wanted to charge me £600 for new TBs, I obviously winced at this and they said they would ask if they could get them repaired for less. I then pointed out to them that, at only 2000 miles, the TB company should be doing the work/replacing for free as they are clearly not fit for purpose. The company agreed (don't know who they are) and six weeks later did the job and returned them! Regards Ivan Link to comment Share on other sites More sharing options...
Eccles Posted June 14, 2009 Share Posted June 14, 2009 Brian, Just been out and can say that there is no running out of puff, it fairly romped into three figures and felt like it had plenty left. Still very happy with it 😬 Ivan Link to comment Share on other sites More sharing options...
Windy Corner Posted June 15, 2009 Author Share Posted June 15, 2009 Spoke to James at Dartford (as Brett wasn't in) The upgrade should be free, takes about a half hour to reflash the ecu and recalibrate the Throttle Position Sensor. It apparently hasn't been rolled out yet, but they have started doing some, he mentioned that he had already recived an ECU via the post........ I think, unless you ask for it, it will get done at the next service. Mine should be in on Wednesday, will report back then Rik Roadsport SV 1.6 Sigma 150 in Viper Blue here Link to comment Share on other sites More sharing options...
Windy Corner Posted June 17, 2009 Author Share Posted June 17, 2009 Just got back from CCM (no, it didn't take that long, but I had to go the long way to work, just to test it out of course 😬) Well, I though after the last round of mods, it was as good as it got............ It just got a whole load better 😬 😬 Better idle, smoother 900 rpm instead of 1000rpm No flatspots Instant response (no delay or chug) Much smoother power delivery, plant your foot, and it just keeps on going !!! I can actually believe now that it may be a 150 bhp model, as before I had my doubts !! The permagrin is back again 😬 Thanks to all at CCM, and Ivan for being the Guinea pig (BTW mines at Revision H, CCM never got Rev G ?)

bob-the-b Posted June 17, 2009 Share Posted June 17, 2009 Seems like you have really been through the wringer. Look forward to meeting when I've got my K series Roadsport from CCM. It's still on their web site , it's the R reg yellow one. Link to comment Share on other sites More sharing options...
Eccles Posted June 17, 2009 Share Posted June 17, 2009 Glad to hear your upgrade went OK Rik It's brilliant isn't it? 😬 😬 A big to CC and Robin etc. for their work, it's tansformed the car. Ivan Link to comment Share on other sites More sharing options...
Windy Corner Posted June 23, 2009 Author Share Posted June 23, 2009 Final Update Th car was at Northampton Motorsport this morning, for a rolling road run. This was to have been a mapping session with reflashed ecu's etc etc. In the end, and on discussion with Troy, we decided to benchmark it only, as the latest (Rev H) Caterham map seems to have done the trick. The car is now as good as I need it, and with the updated map, is the car it should have been all along. For those interested in numbers these are below, the plot can be seen at here Theoretical - 150 bhp @ 6900 rpm, 120 lbft @ 5600 rpm (Flywheel) Actual 142.4 bhp @ 7396 rpm (corrected to flywheel) 109.7 lbft @ 5468 rpm (corrected to flywheel) which when measured at the wheels - 120.1 bhp @ 7040 rpm I won't lock this thread as others may still be able to usefully contribute to it and help out each other. I would be interested to hear how others have got on with the latest map, as far as I know Eccles and I seem to be the only ones to admit to it (perhaps everyone else is still grinning too much) Rik Roadsport SV 1.6 Sigma 150 in Viper Blue here Link to comment Share on other sites More sharing options...
Pete-B Posted June 23, 2009 Share Posted June 23, 2009 Took mine into Midlands CC yesterday morning, picked it up in the afternoon and all I can say is "Spendido, Bellissimo ". It didn't miss a beat all the way home, I waited till this morning to see what it was like from cold. I can state it's the first time that I was able to rev this engine without it cutting out. Hats off to CC for persevering and eventually sorting this problem out. Peter Link to comment Share on other sites More sharing options...
Farreaster Posted June 23, 2009 Share Posted June 23, 2009 I'll be taking my ECU back to the UK and to Caterham Midlands on July 2 for the new program. Should have it back on the car by July 8 - I'll report back to this topic then. Link to comment Share on other sites More sharing options...

exfordy Posted June 25, 2009 Share Posted June 25, 2009 I called in to CC Dartford this morning and had the new mapping. I did ask James what else would be done and, if I remember correctly, he said that the map sensor would be disconnected and blanked off. (Must take a look at that) So - it is better but I wouldn't say it was a transformation. My last map was May 2008 so I don't know how good an iteration that was compared with today's. Now it doesn't pop and bang at all on overrun like it used to (makes Dartford Tunnel blats less amusing...) but it does pop and bang on low speed down change blips which I don't remember it doing before. Weird. More weird is I am convinced that it gives similar performance to before on less throttle. I'll be interested to see what cold running hesitation is gone. It wasn't much of an issue but it would falter if you were a little exuberant. James Gibson said the work would take half an hour but I waited almost an hour and a half. But they did give me two coffees, replace the missing 'CATERHAM' sticker on the cam cover and the missing strap on my side screen foc so all in I am pleased.

exfordy Posted June 25, 2009 Share Posted June 25, 2009 If I am right about the same performance for less throttle it might be interesting to see if fuel consumption is better. Last year a 790 miles trip to Dartmoor gave 25.3 mpg (either motorway blast or country lane crawling). What do others get?
