View Full Version : How does the CTS and IAT affect AFRs?

By how much does it enrich fuel?
At what temp/voltage does the ECU stop adding fuel?
Is it an on-off enrich or is it scaled?

I ask because I deleted my MAF sensor (AEB). When warmed up, it idles and drives like normal. But when the coolant is still cold its barely drivable.

Another confusing part is, my AFR readings are leaner when cold vs when warm.
