Discussione: edc16u1 - limitazione gasolio e turbo oltre la soglia impostata dall'ecu

Yes, For opening vnt you must decrease the value.
If you have overboost with original file, then could be stuck vanes.

For example, AFR target of 17:1 without smoke.
If you put 2100 mbar at 4000 rpm, you are near 915 mg/hub of air.
915/17=53,8 mg IQ

You change lambda from 1,589 to 1,172 to allow that IQ.

With my setup at 4000 rpm I map iq 8200 mmg ( equivalent to an increase of 2563 points ) , while on the lambda always at 4000 rpm we have values ​​1589 points ( original because I have not yet touched the lambda ) . The car does not smoke so much ... but I do fault what have explained above .would you do me the proportion who say so in practice ? So I understand better .
Thank You

?In which map have you put 8200? ?Driwer wish, torque limiter or NM to IQ conversion map?
Well, 8200 should be 82 mg of IQ, factor:0,01.

a when Increased map qi a 8200 AFTER the Maps Lamda , I make the cut ... let me Calculation More explicit and not directly the result Surrounding final . you were talking about this map iq or for which the ratio afr ? Street Address? Thank You

Let?s make another example.

In TL at DDF04 you request 314 Nm at 4000 rpm in the last row.

From NM to IQ map at E0796, 314 Nm need 53,9 mg IQ at 4000 rpm.

In Lambda at DFEC0 you can see 1,589 at 4000 rpm supposing MAF=1000 mg/hub

But 1000/1,589/14,5 = 43,4 mg IQ allowed and you want 53,9 mg IQ.

Then lambda should be 1000/53,9/14,5 = 1,279

Of course, Driwer wish values need to be higher than TL values.

Excuse me , but do not understand where you find the value of 53.9 mg on the map IQ E0796. I Checked a 4000 rpm Values ​​Are Different ! thanks
The amount on the map turbo where you find her ? You could write the addresses and mg iq you say ? I'm having trouble following you with values
