Rotary setup and tune

[Niklas Sandstrom]

I have an Mazda 20B rotary with ITB´s and peripheral ported with an supercharger. There is an Map sensor after the ITB´s do I need an boost sensor before also?

What is the right way to setup and tune that?

I have tried to follow the CTN0036 guide but I cant find the boost and Engine Efficiency Airbox
compensation table

Engine efficiency mode: Manifold Air Density
Engine Load Normalised: Throttle
Inlet manifold Pressure: Estimate
Inlet Manifold Pressure Estimate: Boost Pressure Relative

Hi Niklas,

If you don't have a boost pressure sensor, the boost pressure is calculated from the manifold pressure.

When inlet manifold pressure is set to estimate (ie. it does not reference the manifold pressure sensor) then your MAP sensor should be assigned as a boost pressure sensor or Airbox pressure sensor.

If you used the engine load normalised option of Throttle, I would like to point out that this means the timing at 100kpa and 100% throttle for a given engine speed will be the same as the timing used at 300kpa and 100% throttle.

The compensation tables are not in the Rotary packages. I have flagged this with our firmware engineers, and it will be added in the next update (no ETA on timeframe)
