Mr2cycle5 Posted November 6, 2018 Report Share Posted November 6, 2018 Hi, Only had the car a week, but now know it runs terrible when first fired up in a morning from stone cold. It starts on the button, idles fine and has never cut out. The problem starts when I first drive the car. Power totally drops off and I can see from the wideband that it goes far into lean. I've included the base map and a log I've compared the post start enrichment and warm up enrichment figures, from my base map to the stock G4+ map and can see a variance in values. My question is, can I simply change my figures to match? Or do I need to take other factors into consideration (modifiications) and make incremental alterations instead? Any advice would be much appreciated. Edit. So the lower the cell number equates to a richer fuel setting...It looks like the lower values I already have set, suggest it would run richer than the stock base map. Does that point towards a faulty o2 sensor or something else that’s at fault? K40 SKY Base Map.pclr K40 SKY cold start.llg Quote Link to comment Share on other sites More sharing options...

No, a smaller number means less enrichment (less fuel, leaner). Post start enrichment is only active for a few seconds after start up so it is unlikely this table is your problem so forget about that for now. It sounds more like your warmup enrichment table needs work. Quote Link to comment Share on other sites More sharing options...
Mr2cycle5 Posted November 7, 2018 Author Report Share Posted November 7, 2018 Ok great, thanks for that. I'll alter the warm up enrichment figures halfway towards the base values first and see what difference it makes. Quote Link to comment Share on other sites More sharing options...
AbbeyMS Posted November 7, 2018 Report Share Posted November 7, 2018 Looking through your CAL I dont see any inputs for a Lambda sensor input or a CAN Lambda set up? So do you have a Lambda sensor/gauge fitted but not fed back into the ECU? Quote Link to comment Share on other sites More sharing options...
Mr2cycle5 Posted November 7, 2018 Author Report Share Posted November 7, 2018 Yes, theres an Aem wideband gauge fitted and working, but it isn't connected to the ecu. Quote Link to comment Share on other sites More sharing options...
Mr2cycle5 Posted November 9, 2018 Author Report Share Posted November 9, 2018 Having now loaded the base warm up enrichment table to the ecu, it’s running great on first kick up in a morning thank you. Quote Link to comment Share on other sites More sharing options...
