Hi, my name is Len.
i have a BMW 320ci M54B22 2000 coupe.
Rebuild the car to a lot of M3 specs.
muffler incl bumper
air vents in front screens
hood
cluster
leather sits
wheels
etc etc ..

For the cluster electronis i used NCS expert to configure.
For ECU software i use GALLETTO 1260

I am searching for good ECU edit software, and help on how to tune urself ... I'm learning here, not searching for the cheapest way to get a tune ...

I am an electronical engeneer, repairing musical instrument and amplifiers ... specialised in guitar amps.
