For the occasional dyno or single gear log maybe not that important.

What car is this for? All F series I see are usually in the 15/14 AFR range from factory.

It's a 135i. I don't know why usually on the dyno I can't get good AFR figures, my guess is it doesn't create much load, but on the street this car is running 13.1-13.0 AFR

E series N55 likes to run richer than F series, so that is normal. Best is to compare the logs vs the sniffer in the rear to see if it is working. More than likely the sniffer in the back is not calibrated %100. Logs will be more accurate to a certain extent.

Let me look for some logs for local cars.
Thanks. Do you know if any of the DCT cars are running the stock dmfw? And if so, are they having any misfire issues above 19ish psi?

Thanks. Stock flywheel? What flash are you running? You don't get any unexpected misfires where the log looks perfect but the car throws a cyl 5 or 6 misfire code?

Thanks. So youíre saying you can go beat on your car all day and you donít get misfires here and there? like in half mile event, track day, or even aggressive Street driving? Why can you do that and pretty much no one else can run more than 19ish psi without upgrading the flywheel?

Could you give more insight on this, Did your early n55 hpfp and everything bolt into the F series block? and did the DCT bolt right into the motor with the ZF8? And what did you do for the DME? Thanks in advance

The only thing i had to change was the HPFP and the connection to block and the sump and valve cover. Gearbox fitted the same. My e series harness worked. All plugs to engine was same.
