Hello all,

My question is concerning the boost signal using an external GM 3BAR map sensor. I have a Mazda MP3 (with Mental Addiction 2nd Gen Turbo Kit). When looking at the gauge page, text map, and 3D maps in the Windows software, I can see that the boost signal is fluctuating back and forth, and is not steady. While viewing any of the text maps, I get jumping cells (boost reading is back and forth) While observing tuning session on a friend's car (Mazda MP3 with HiBoost Turbo Kit) with the E6X that has the 2.5 Bar INTERNAL MAP sensor, the boost signal is smooth, and steady, and does not fluctuate back and forth.

My question is if there is a way to make the boost signal steady for the external GM MAP sensor? Does anyone know of any inline pulse dampeners/restrictors that would help? I have a Defi D-Series Boost gauge, and it doesn't fluctuate like my old Cartech boost gauge did. I figure it must have some type of pulse dampener.

Well that could indicate that your turbo is operarting close to, or to the left of the surge line. I know that you said you are using a kit, but is the turbo in that kit PROPERLY sized for the engine.

What did you expect?
This is an RX-7 Forum, not an MP3 one.
