Altezza.RS Posted April 2, 2020 Report Share Posted April 2, 2020 As the title suggests I'm having cold and warm start issues. 8/10 times I have to swing long to get it to start. I've added fuel to the crank enrichment and prime tables to the point where it back fired once or twice Quote Link to comment Share on other sites More sharing options...
Simon Posted April 2, 2020 Report Share Posted April 2, 2020 Have you tried going in the other direction with less additional fuel. Check you are getting RPM and no trig 1 errors during crank. Make sure ECU is staying on line during crank. Take a log and post with a copy of your map. Quote Link to comment Share on other sites More sharing options...

Adamw Posted April 7, 2020 Report Share Posted April 7, 2020 Can you try this. I have lowered the arming thresholds and put in way more crank enrichment and pre-crank prime. 3sgebaserev8.6 Try this.pclr Quote Link to comment Share on other sites More sharing options...
Apex Speed Tech Posted April 7, 2020 Report Share Posted April 7, 2020 Also could the 9.4V under cranking compound the issue? I have plenty of cars that crank around 10V but you have to be diligent with your dwell & inj battery offset settings..... Quote Link to comment Share on other sites More sharing options...
Altezza.RS Posted April 10, 2020 Author Report Share Posted April 10, 2020 Thanks this seems to help but theres the smell of fuel now after it starts, guess a little of the extra fuel needs to be taken back out maybe from the prime? Quote Link to comment Share on other sites More sharing options...

Having said that your lambda calibration looks wrong, what wideband controller do you have? Quote Link to comment Share on other sites More sharing options...
Altezza.RS Posted April 10, 2020 Author Report Share Posted April 10, 2020 AEM 4.9 Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 10, 2020 Report Share Posted April 10, 2020 10 hours ago, Altezza.RS said: AEM 4.9 That doesnt help much. If it is one of the older non x-series such as 30-4100 then your cal table is wrong, it should look like this: If it is one of the X-series models then it is still wrong, just set the analog input calibration to "AEM X-series".
