4-Port Map SSV
Posted: November 24th, 2025, 12:22 pm
Noticed when looking at my current tunes, that it's showing no changes in the 'Intake Air Valve Control' when compared to the stock tune for my 4-Port manual RX8.
I then looked at the base map, and indeed the SSVs the same, which looks incorrect to me.
The SSV appears to be set to always open once the coolant is > 20 degrees?
Have attached a screenshot.
For reference, the VDI is set to 5750RPM which I believe is the stock value for the 4-Port.
My ECU calibration is: N3H8EM00013S5F10
This has me worried about all of the values in the base map now...
Appreciate any input.
