LawrenceR Posted March 30, 2016 Share Posted March 30, 2016 Does any one know what the red line is set at for a Duratec SSR/R400 with the 220 bhp Caterham upgrade?Thanks Link to comment Share on other sites More sharing options...
martyn Posted March 30, 2016 Share Posted March 30, 2016 Well there is one easy way to find out....The MBE ECU has a soft cut limiter that is usually set one or two hundred RPM lower than the hard cut. It wont cause any damage to gently run into this limiter. As long as you don't do it every single gear change.If you really don't want to do that then you can plug into a laptop and use the Easimap software to see what the soft and hard cut limits are. You'll need some hardware or a cable of some sort for this though. Link to comment Share on other sites More sharing options...
John Vine Posted March 30, 2016 Share Posted March 30, 2016 Martyn, I could probably do that for the OP if you could explain what I need to do. I've got the MBE cable but simply lack the requisite knowledge!JV Link to comment Share on other sites More sharing options...
martyn Posted March 30, 2016 Share Posted March 30, 2016 Easimap can be downloaded from here: http://www.sbdev.co.uk/Engine_Management_Systems/ECU/Easimap6_Download.htmPlug it all in. Start the easimap software. Then turn on the ignition or even start the engine.You should see all these guages and numbers come to life. I believe the Soft Cut and Hard Cut are shown on the default home screen (you can see them here in the bottom right). If they aren't there you can add them by clicking Page > Add Panel.. You'll then find them under the "Engine Speed Setup & Limiter" section. There are literally hundreds of other parameters in there that you can view in real-time as the engine runs.

John Vine Posted March 30, 2016 Share Posted March 30, 2016 Thanks, Martyn. As it happens, I downloaded Easimap some while ago, but hadn't realised that the basic page carried the Cut values!Anyway, for the OP, my values are: Soft Cut: 7800 Hard Cut: 7900This is on a 2008 R400D, upgraded to RBs (220 bhp) by CC Crawley in Dec 2014.Edited to add the evidence:JV Link to comment Share on other sites More sharing options...
martyn Posted March 30, 2016 Share Posted March 30, 2016 You can use easimap to check your TPS calibration as well. Call up a panel called "Throttle Site 1". It should read "0.0". The slightest touch of the throttle should move it off "0.0" If you can noticeably move the throttle pedal without the site increasing then you need to adjust something. Watch the "Throttle Angle 1" panel (already present on your home page) as you do this. If the throttle angle voltage is increasing but the site is not then you need to adjust your TPS.If neither the throttle angle voltage or the site are increasing then you don't necessarily have a problem with the TPS, but you do have too much slack in the throttle cable. Readjust the cable tension then try again.Its also interesting to see what site you get at wide open throttle, although this is mostly only useful as a sanity check to see if you're registering WOT when adjusting pedal stops.

John Vine Posted March 30, 2016 Share Posted March 30, 2016 Hi Martyn,I tried the tests, with these results: TS1: 0.0 at rest and 14.4 at WOT -- increased the moment I touched the pedal TA1: 4.63v at rest and 1.38v at WOTDo these seem OK to you? Note that the TPS voltages are the reverse of "normal" -- a Cosworth quirk, apparently.JV Link to comment Share on other sites More sharing options...
martyn Posted March 30, 2016 Share Posted March 30, 2016 Yep, thats exactly what you want. If you ever need to remove or replace your TPS you can use these values to position the new one exactly as it should be.One last test I forgot to mention is to rotate the throttle linkage on the bodies around to its stop by hand and see what Site you achieve then. If, for example you can get higher than 14.4 by doing this then your pedal stop is set too high. Its unlikely because that should have already been set, but its always good to check you dont have an extra few mm of pedal travel hiding under there Obviously have the engine switched off when you do this.Sorry to the OP, its gone a bit off topic Link to comment Share on other sites More sharing options...
