Hey,

I have 1.9 TDI PD ARL with firad 120% nozzles and GTB2260VKLR turbo. I am trying to calibrate nozzles and no luck for now.

Does any one know exactly how much more fuel does Firad 120% compared to stock 550cc AL nozzle.

I have tried multiplaying y axis in doi and x axis in soi with 1.6 (60%) the car goes well but i can see that nozzles actualy inject less fuel because I have IQ by MAP with AFR 18 car doesent smoke but consumtion on trip computer goes to 11l/100km which is not right.

Then i multiplied axis with 1.45 because i found somewere that firad 120% actualy injects 45% more fuel then stock AL nozzle but thats also not right

Can anyone help?

Thanks in advance willing to pay for working solution
