Altezzalink cold/warm start issue

Recommended Posts

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

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.

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.....

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?

It would probably be better to tune it with the lambda probe rather than go off your nose.

Having said that your lambda calibration looks wrong, what wideband controller do you have?

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".
