RS, when we do that clamping for 2.9v for all rpm tables, what will be that max boost the stock MAP can handle? Any effect when u clamp it to 2.9v? sori, still exploring all the functions in Emanage...
Basically what it does is that the ECU will handle everything below atmosheric pressure and emanage handles the engine once you are in boost.
So once in boost the ECU will have steady values as if it were NA engine and your emanage map will +/- onto that steady ECU map.
That is when you use additional injection map to maintain proper air fuel ratio under boost.
For emanage blue, effectively u tune the engine using TPS as load below boost and using map sensor when in boost. That way your map will be nice and clean and easy to understand.
In your additional injection map lets say you have 12.5:1 AFR at 0 bar.
if you :
+10% @ 0.1bar
+20% @ 0.2bar
+30% @ 0.3bar
.
.
.
+100% @ 1bar
You will maintain more or less 12.5:1 AFR whenever in boost.
Clamping at 2.9V only prevents ECU from seeing boost but emanage will still be able to measure boost. The max boost you will be able to read is ~0.8 bar in your case. That is the limit of the Honda stock map sensor.
To know the maximum value that a map sensor can read assuming you are at sea level (much higher altitudes will render this formula invalid):
Turn on the engine. Don't start. See the voltage of the map sensor. Lets say 2.78V
Use this formula:
Maxboost (bar relative) = (5/<mapsensor voltage with ign on but not start>) - 1
so
(5/2.78) -1 ~= 0.8 bar
for a mitsubishi sensor
(5/4.1) -1 = 0.22 bar
