Martin J Posted March 26, 2013 Author Share Posted March 26, 2013 Just been looking at your build photo's Grubb 😶🌫️ The film you are applying looks like the stuff I used years ago to cover my R/C aircraft. It looks a nice finish but must be a bit awkward in places. Link to comment Share on other sites More sharing options...
charlie_pank Posted March 27, 2013 Share Posted March 27, 2013 If the rev counter is flickering, does it make you wonder whether there's a weak spark, or if the ECU is receiving (and acting upon) the same dud information that the instruments are getting?

Leadership Team Garry7 Posted March 27, 2013 Leadership Team Share Posted March 27, 2013 FWIW, when I had the issues with my rev counter (prior to the engine out and re wire) even when it was flicking around zero although under full throttle, the engine ran perfectly and the rev limiter cut in OK (on the odd occasion I really pushed it!!).

charlie_pank Posted March 27, 2013 Share Posted March 27, 2013 You buy a car from the people that make them, and part of it doesn't work. Yet people are shrugging and living with it! That's serious customer 'loyalty' Link to comment Share on other sites More sharing options...

Area Representative Iain McCallum Posted March 27, 2013 Area Representative Share Posted March 27, 2013 My self-build Sigma 150 in 2011 had the flicking tacho and 'strange' oil pressure symptoms. The only time the OPG registered correctly was when I had to do the initial cranking of the engine during the build! Now it registers pressure but only linearly - keeps on rising the hotter the engine gets but never fluctuates or drops down on idle. I had replaced both the OPG and the sender with no changes, and on the first service last year CC Midlands couldn't fix it either. I think a 'proper' sender and guage is needed. Apparently the OPG is fed from the tacho so I also replaced the tacho (to try to lose both problems) but that didn't fix them either. However car runs as sweet as a nut so not that concerned especially as the DRE shift lights have added a new dimension to blatting! 😬 Iain Link to comment Share on other sites More sharing options...
Stationary M25 Traveller Posted March 27, 2013 Share Posted March 27, 2013 Fit a mechanical OPG ...... dirt cheap and very reliable ! Link to comment Share on other sites More sharing options...

It would seem several things are fed via the tacho. On my 07 sigma the fuel gauge was very unreliable, caterham sent me a new tacho to plug in to rectify the problem & this did seem to fix the fault. When various components are interlinked it does complicate things. Link to comment Share on other sites More sharing options...
Area Representative Geoff Brown Posted March 28, 2013 Area Representative Share Posted March 28, 2013 CC have OP sender problems. Just finished build of R400 & the shortage list on delivery sited a recall on OP sender. Replacement duly arrived a week later. Seemed senseless outing a brand new sensor fitted to a zero time engine but did it any way. On cranking OP fine and on wet start OP fine. Recalled sensor by Danfoss. Replacement by 'Caerbont Automotive Inst Ltd'. Lets see what happens in long term service......?? Link to comment Share on other sites More sharing options...
TobyCoulson Posted March 28, 2013 Share Posted March 28, 2013 My Sigma has never suffered from any of these problems apart from the fuel gauge which I realise now is just something to fill a hole in the dashboard.

Stationary M25 Traveller Posted March 28, 2013 Share Posted March 28, 2013 I would have hoped Danfoss would be more reliable .... back to Caerbont Link to comment Share on other sites More sharing options...
