tiddy1 Posted July 4, 2004 Share Posted July 4, 2004 When my engine is hot, i.e just finished a session on the track or a sprint I usually let it run for about 10 minutes to cool but if I switch it off it will inlt start about 20% of the time, just turns over, almost and sounds like a dead battery, leave for a further 30 mins and it starts like new/fully charged battery. Could this be the emerald map? temp compensation or is it just getting too tight when hot? Any suggestions Simon Link to comment Share on other sites More sharing options...

Anders Sweden Posted July 5, 2004 Share Posted July 5, 2004 Hi there! I am sorry not being abe to help you with this but I see that you're engine is the same spec as mine. I am about to finnish the building of my car and will try to start for the first time in about a moinths time. As you an understand I need lots of various maps to get it runnin well. Any chance I could have a copy of yours? Kind Regards Anders Link to comment Share on other sites More sharing options...
Jason Plato Posted July 5, 2004 Share Posted July 5, 2004 Check the advance . You should have/need less than 6 degrees . Its at the bottom of the "Ignition" screen . It sounded to me like the advance was preventing the engine physically turning over , this was exagerated when hot . Dave Link to comment Share on other sites More sharing options...
tiddy1 Posted July 5, 2004 Author Share Posted July 5, 2004 That was my thought dave but I was not sure if the advance at cranking was effected by the temp compensation, I will have a look but as I have no laptop that involves carting the computer into teh garage and I was hoping not to have to do that . simon Link to comment Share on other sites More sharing options...
Leadership Team SLR No.77 Posted July 5, 2004 Leadership Team Share Posted July 5, 2004 Simon, you're correct in that you can only set one figure for ignition advance at start-up, but be sure, as Dave states, that it's less than around 6deg. Any more and the engine will possibly appear to slow during cranking, imitating a dodgy battery. Possibly also try the start-up enrichment settings on the coolant temp page - may be set a little rich? Stu. Link to comment Share on other sites More sharing options...
