hi guys im trying to tune a car that its semi pp and the map reading at idle are hi and light throttle area fluctuate a lot its there a way to use throttle for low loads and map for hi load boost area on a single table and how to use it.thanks

 

are you getting the map signal from one rotor or both ?

 

both

 

That's simply how a large port acts. Very little between full vacuum and atmospheric.

You're going to want to use alpha-N to tune the light load areas, then speed density into boost.

 

can I do that in just one table or I have to use to tables one for alpha n and the other for map.thanks

 

Honestly I can't answer that question as I have not tuned a blended setup.

Check the documentation.

 

2 tables will work better for that. I would suggest table switching rather than blending...

What firmware and MS are you using? The signal might be more stable with later versions of the firmware for ms3... We added a new method of averaging there.

im using ms2 extra 3.2.5 code

 

Yeah, if you can find an event average setting for MAP sampling that might help. If not updating to a firmware that has that setting might help.
