Alex,
are either or both of these tunes for a s65 with the vanos units functional? I am installing the s65 into an e90 race car and want to keep the vanos functional.
Regards,
Ralph

Both of them have the VANOS control on. The S65 uses the later type VANOS, so it's very simple to control, just like a standard VVTi system.

Hi Alex,
Will the S100 control the electronic throttle? You sent me two base tunes, do these tunes have control the electronic throttle?

Hi Ralph

Neither of them have electronic throttle activated.
We cannot do that yet, as there are two actuators and sensors on this engine, and the S series can only control one actuator.

Zomer Motorsport in the Netherlands provided the base map, so it would be worth contacting them to find out what throttle body they used.

The throttle actuators on this engine are driven by a CAN protocol.
The S85 V10 uses the same actuators.
You can't control them out of an aftermarket ECU as the Protocol is rather complex due to safety requirements.
Use mechanical throttle linkage or try to modifiy the actuator, that it can be driven from a 4Q-bridge as a positioner. ;)
