irrotational Posted September 23, 2011 Share Posted September 23, 2011 I have searched the archives - I *think* K series cars have a MEMs ECU and I *think* this has an EOBD port which is labelled as a j1962 plug or something. My question is can you get out live information on revs, throttle position etc? Edited by - irrotational on 23 Sep 2011 12:04:38 Link to comment Share on other sites More sharing options...
Frying Pan Posted September 23, 2011 Share Posted September 23, 2011 I *think* K series cars have a MEMs ECU - Correct for non-throttle bodied engines (original R3/4/500 - later R300s had VVC engines with MEMS) I *think* this has an EOBD port which is labelled as a j1962 plug or something - Correct - should be dangling somewhere near the steering column and is a large 16-way connector with nothing connected My question is can you get out live information on revs, throttle position etc? - Yes - for EU3 cars (coil on plug) you can use a generic scan tool Link to comment Share on other sites More sharing options...
gundersen Posted September 23, 2011 Share Posted September 23, 2011 Super info, I am off to buy a ODB-II to bluetooth adapter and the android track app then :) Link to comment Share on other sites More sharing options...
CharlesElliott Posted September 23, 2011 Share Posted September 23, 2011 BUT - data rate is very slow, and it is really impractical to use for 'real time' monitoring on track etc. Link to comment Share on other sites More sharing options...
irrotational Posted September 23, 2011 Author Share Posted September 23, 2011 ah - thanks Charles... I have no idea if mine is EU2 or 3...it's a 1997 superlight (from SL and SLR days, pre R300 etc) Link to comment Share on other sites More sharing options...
gundersen Posted September 23, 2011 Share Posted September 23, 2011 As far as I could read (very briefly) on the aLapRecorderHD forum, the data rate is dependent on the instrument used to read the values? Of cause the rate will probably be limited by the ECU speed also... Link to comment Share on other sites More sharing options...
Area Representative Richard Price Posted September 23, 2011 Area Representative Share Posted September 23, 2011 I have no idea if mine is EU2 or 3...it's a 1997 superlight (from SL and SLR days, pre R300 etc) A 97 car will be EU2. EU3 Caterhams first appeared in around 2001. Link to comment Share on other sites More sharing options...
irrotational Posted September 24, 2011 Author Share Posted September 24, 2011 Ok so I can't get any data anyway? Appreciate everyone's replies! Link to comment Share on other sites More sharing options...
gundersen Posted October 6, 2011 Share Posted October 6, 2011 Finally the cheap OBD adapter has arrieved, and I was able to do a quick test in garage. It seems that the speed is ok, about the same as on my 2006 VW disel. I would guess that it is no more than half a second behind. I will do an update when I get a chance to take the car for a test drive :) Link to comment Share on other sites More sharing options...
Rullingen Posted January 22, 2019 Share Posted January 22, 2019 "Correct - should be dangling somewhere near the steering column and is a large 16-way connector with nothing connected"Is this the ODBII standard connector or does one need to make an adaptor?Rob.

garybee Posted January 23, 2019 Share Posted January 23, 2019 Standard connector, nothing special needed. If in doubt over whether or not your car is MEMS2 or MEMS3 just look at the ECU. If it's wedge shaped you're MEMS3. Link to comment Share on other sites More sharing options...
