Jake Posted July 21, 2007 Share Posted July 21, 2007 The hot start on my car isn't very good. Typically it turns over for 2 to 3 seconds before the engine fires up. Ryan did have a play about with the startup AFRs but it didn't make much difference regardless of whether he leaned it off or richened it up. I've been reading this article on the Motec web site which suggests that an injector timing of about 275 degress BTDC generally works well. Looking at the settings in my map the Inj Timing seems to be set around 373 to 400 DBTDC. (Screenshot attached below) Would it safe for me to knob about with this? I presume I only need to change the values for 0 and 500 RPM - is that right? Thanks Link to comment Share on other sites More sharing options...
SimonB Posted July 21, 2007 Share Posted July 21, 2007 I've only got an RPM axis on my injector timing table, and it's pretty much 400 everywhere. You shouldn't need to arse about with it really I think. Link to comment Share on other sites More sharing options...
Jake Posted July 21, 2007 Author Share Posted July 21, 2007 Yeah but I'm trying to figure out why the hot start isn't very good. Link to comment Share on other sites More sharing options...
SimonB Posted July 21, 2007 Share Posted July 21, 2007 Fair enough. Can't see it doing any damage fiddling with it. Link to comment Share on other sites More sharing options...
