Hi all.
I have now 550cc injectors and i put KVB to 550 from 386 who was from original BAM ecu file.
FKVA in original file is 1.0625 for 386cc , somebody know why? I think must be 1.0000!
Must i modify FKVA to 1 for my new 550cc injectors?
Thanks in advance

I checked again for 2 different file for
8N0906018SJ and 8N0906018SJ and 8N0906018H 0004 and the definition are ok at 0x1A477 with this conversion eeprom*0.625 and result 1.0625 value in tuner pro and winols too
for 8N0906018BP_0002 value in winols is 1.00
Something is strange
in the left is 8N0906018BP_0002

Reply after some time but maybe tell something more

Yes FKVA is 1,0625 not 1 because KVB is 371,72 not 386 but really injectors are mor like 394
and for 1,0625 x 371,72 we have ~`395
And for me if I take 395 as size when go from 3 bar to 4 bar fpr my KRKTE is 0,2% wrong so for me thats why constant are 1,0625 not 1

For injectors that flow more than 776cc why not just multiply the conversion factor for KVB by 3, put in your normal injector flow rate, then set FKVA to 3. This way you wont need to recalibrate FKVA vs actual mpg much and dont have to guess.
