Doubt about my A/F Ratio

tjaartk · 09-11-2011, 02:13 AM

Hey Vince,

Managed to get the AFR readings back - had to reload Cipher. Still battling with the hot start issues. Car starts perfectly when cold. Idles and runs perfectly. As soon as the water temp goes over 20 degrees C, the car won't start unless I help it with the Accellerator pedal. Apparantly there is a new patch coming out for the ROM editor which gives more tables for the cranking fuel enrichment - Omar at Uprev as reference.

I have the GTM stg 1 SC. Our altitude is 6000 ft.

I see I get a 14% fuel correction at idle to get it to target idle AFR. Looks like it is adding fuel to get it to idle. Not sure what this will mean for cranking enrichment.

Your advice will be appreciated.

This is a very annoying poblem to have - having your car not fire up in the parking lot, with all the M3 drivers laughing at your car...
