I have a 1.2 8v turbo project, and am running a MF2 for fueling:

Would anyone know the easiest way to work out the fueling, i've done some calcs but not sure if they are correct. I'm running it in 3D, with four injectors...

the car runs a GT1549 turbo

I can calculate approx how much fuel i need at each rev point, but I'm not sure about the gain for manifold pressure

It runs an hks boost controller, with two points approx 1bar and .5bar

-Any ideas??

You can not set up accurately an MF2 (in fact any type of fuelling) with out it being on a rolling road and with the rr's wide band lambda sensor plugged in to read fuel levels.

This is where you may need to get a 2nd Lambda boss welded onto the exhaust down pipe to take this as well as standard lambda.

There is not just the fuel map, but the gain control to set up as the MF2 is clever enough to read different throttle positions and boost levels and fuel accordingly if set up correctly like mine (Finger99 now) was and Emma's turbo Cinq is now.

Do not try and set it up just by twiddling the controls you will get nowhere and have it lean and rich everywhere.
