Title: How does Me3.8.2/3.8.3/5.9.2 compute fuel?

How does Me3.8.2/3.8.3/5.9.2 compute fuel?

I could only find (what looks like) part throttle map. (3.8.2 - 92b4 / 5.9.2 - 9510). It looks like it's only a correction map. (Values - 128)

Me3.8 compute fuel just like ME7 , you have conversion from main load that is MAF , then it convert with formula fuel in ms that is need for 14,7:1 lambda.Then apply all of corrections .
You have always calculation for Lambda 1 in load ms.

hello,i dont wont to start new topic so i ask here

This ecu calculate fuel from MAF map,withc are the abreviatures in damos for the fuel maps and corrections? what i need to change if i wont to open the injectors more?

thank you

MAF + throttle angle!

Throttle angle (alpha-n) is used in case of defective MAF. In normal operation it is used for wall film model, everything else is MAF based.

ok,witch map is the MAF map?and how i need to correct it to inject more fuel?

no one can tell how to make ecu inject more fuel?
