TobyCoulson Posted April 22, 2009 Share Posted April 22, 2009 It's a shame the prices aren't mentioned. Always scares me when I see that 😬 Link to comment Share on other sites More sharing options...
Windy Corner Posted April 23, 2009 Author Share Posted April 23, 2009 That would make sense for the 125 Sigma, but for the 150, hardly seems worth it. Anyone ever got an ECU pincode from Caterham ?? as I suspect to do anything useful to that engine you would have to remap it ??

TobyCoulson Posted April 23, 2009 Share Posted April 23, 2009 That would make sense for the 125 Sigma, but for the 150, hardly seems worth it. Yes I couldn't agree more. If I was going to upgrade mine I'd be looking for around 175/180 bhp to make it worthwhile. Link to comment Share on other sites More sharing options...
jchasey Posted April 23, 2009 Share Posted April 23, 2009 Before going for the Minister upgrade I'd ring and check what target bhp they are doing now. Having had my engine 125 Sigma upgraded at Minister they were substantially lower than their target (based on their test), although it did improve a fair bit from where it was. Don't think they have upgraded the web site since... Link to comment Share on other sites More sharing options...
Windy Corner Posted May 28, 2009 Author Share Posted May 28, 2009 Some more news Had a chat with Robin at the Factory yesterday, explained that although all was mostly well, there was still some flatspots and I was thinking of getting it looked at to see if anything could be done with the map. Was there any chance of the pincode ??? Not surprisingly, there is no chance, apparently they use the same pincode for all ECU's including 125's and 150's which would have disastrous repercussions on the Academy of anyone got to "fiddle" with it. He did mention, though to hold off doing anything else, as they are about to release a new "calibration map". Apparently they still accept although the current map seems to work well on some cars it doesn't appear to be as universal as it could be (my words not his) Apparently (and please correct me as I don't know what I'm talking about) the current map is based on the manifold pressure sensor, but they are changing it to be based on the TPS. The current map (based on the Manifold pressure) is great when it works but not so great when it doesn't. Basing it on the TPS should mean a more universal map that should suit all cars. It should be out in 2-3 weeks, so time then to start pestering CCM & CCS to get it updated (should be free ??) Any comments would be welcome as I am not sure how this black magic ecu stuff works and whether it is likely to make any difference Rik Roadsport SV 1.6 Sigma 150 in Viper Blue here Edited by - Windy Corner on 28 May 2009 10:59:16 Link to comment Share on other sites More sharing options...

Farreaster Posted May 28, 2009 Share Posted May 28, 2009 Wonder how I'm going to get the update here without the pincode, perhaps I should suggest a Caterham staff stagparty in Benidorm Link to comment Share on other sites More sharing options...

Eccles Posted May 28, 2009 Share Posted May 28, 2009 Oooh, I wonder if it's my car they're trying it out on! They've had it for a few weeks now to sort out this problem so with any luch when I get it back I will have this bit done on it! Ivan Link to comment Share on other sites More sharing options...

Windy Corner Posted May 31, 2009 Author Share Posted May 31, 2009 Sorry about that Peter, and I hate jargon . Be interesting to know what they tell you, they did to it, Ivan, when you get it back.

Eccles Posted May 31, 2009 Share Posted May 31, 2009 Hi Rik, Just past five weeks for me so far, and with all this sunny weather we've been having I've started to go carzy with withdrawal and just want to go blatting again!! Even though I would still rather they kept it longer rather than give it back before it was properly fixed. I know it has involved work on the throttle bodies but I'm not sure what and why as yet. I'll certainly keep you all posted when I hear details, just can't wait to get back on the road. Cheers Ivan Link to comment Share on other sites More sharing options...
brianmurray325hotmail.com Posted June 5, 2009 Share Posted June 5, 2009 had my sv150 on the dyno at the weekend and with the current programme "MAP sensor driven" i'm getting about 115bhp at the wheels. i look forward to the new programme, "TPS driven should result in a more accurate "derived airflow measurement" Presumably the MAP will then read/monitor absolute air pressure i.e. open to atmosphere. I really didn't want to be dragged down this road of continualsprofessional development Link to comment Share on other sites More sharing options...
BadBob Posted June 5, 2009 Share Posted June 5, 2009 115BHP at the wheels - doesn't sound a million miles off 150 at the fly-wheel? Link to comment Share on other sites More sharing options...
brianmurray325hotmail.com Posted June 7, 2009 Share Posted June 7, 2009 yeh, i'm reasonably satisfied with that, just needs improved mapping to get the icing on the cake Link to comment Share on other sites More sharing options...
Eccles Posted June 10, 2009 Share Posted June 10, 2009 It's ready!!! My car is now ready to collect with refurbished throttle bodies and the new engine map/set-up. Not sure what else has been done but will find out. Going to pick it up on Friday so will let you all know how it is after my journey home 😬 Ivan Link to comment Share on other sites More sharing options...
Windy Corner Posted June 10, 2009 Author Share Posted June 10, 2009 Ivan, Thanks for the update Can you ask wht revision of map they have put on it. Mine has Revision F, but I don't know if it has changed since April when mine was in.

Farreaster Posted June 11, 2009 Share Posted June 11, 2009 I spoke to Caterham yesterday, apparently the new map "G", based on the TPS, is a real improvement. Should be available later in June.
