I've tuned MS41.1 ECUs but my current car have the older MS40.1.
I can adjust everything except the MAF-table.
I can't run the car with my 3.5 Inch MAF cause the calculated load are way of. Throttle response is horrible. Disconnecting the MAF solves that problem, but I need the MAF to run my turbo setup.

On the MS41.1 the MAF-table 1x256 map is easily spotted but I can't seem to find one in the MS40.1 bin.
If you want to help and need the bin you can find the same version here:

Name: BMW 320 e36 5wk9002_org.rar

This ECU don't even have a checksum and you can change what you want without problems.
If anyone experienced can help me figuring out how the MAF/Load is calculated please do.

I know it's a dead thread, but if someone coes back to try and find the same thing it is address: 0x2C70 1x250
