N/A ITB config choices, and Motorsport Cam Control

[nucci]

I've got a bit of engine tuning/setup experience and I'm investigating whether I can use VEMS to control:

• BMW S54
• 3.25 liter displacement inline-6, 11.5:1 compression
• factory-style Alpha-N airbox (no MAF, ~6" huge opening)
• six 50mm throttle plates
• variable cam timing with 60 cam degrees variable on the intake and 45 cam degrees on the exhaust

In a perfect world I would be able to have the following:

• main fuel table axes: TPS and RPM
• fuel table multiplier: 0-100%, based on kpa (MAP sensor connected to damping manifold after throttle plates
• ignition table axes: kpa and RPM
• realtime baro correction in the range of 1 atm = 97-104kpa

I have downloaded VEMSTune and navigated around the menus quite a bit but I'm not sure which selections would result in my desired configuration.

Also, with regard to Motorsport Cam Control: If I can have my tps-based, kpa-corrected fuel table and my kpa-based ignition table, what will the load axes be for the camshaft control maps?

Any fact-based answers would be GREAT!

Thanks,

Matt

Dual variable vanos(s50, s54) is supported -> http://www.vems.hu/wiki/index.php?page=InputTrigger/BmwDoubleVanos
For now only MAPvsRPM, even when running Alpha-N fueltable.
You have to order ECU with 3rd Triggerinput(probably some highside drivers aswell, run from p259 outputs, write in ordernote).

There is a MAP vs RPM fuel correction table when using Alpha-N 0-255% (100% is No-correction).
Ignition table can be MAPvsRPM when using Alpha-N fueltable.
Realtime baro requires an extra MAP-Sensor on a non-pulluped 0-5v input.
