Throttle body table over load 2?

Post by MiPil »

Hello,

in found one strange behavior in throttle position table.

Maximal value when your throttle body reaches is in line for load=2 (table os to load=4)

When your command a max open in load 2,125 the TB never full opens in this RPM point and follow value in cell to load 2 and actual rpm point.

It's a bug or a feature? :-)

On what platform more specifically? 3MPS BK/Mazdaspeed3 gen1 or 6MPS/Mazdaspeed6?

Is this in the stock tune or one of the OTS tunes?

What value are you seeing and what value are you expecting? Throttle goes to a maximum of about 76-77, in very rare situations you may see it at 78-79%.

Speed6, more details in attached images - TB table + log. Load is 2,45.

Tunes are same - only DBW Throttle body normal and overload tables are changed.

I can send the tune and the whole log on Friday.
