I've been tuning an Evo 7 using Tephra 9055 V7 SD, the map sensor is a bolt-on Omni 3bar, I used the default map sensor scaling in the rom by switching 'Map Sensor KPA' table scaling to Omni 3bar. The values are:
Map volts--- KPA
0.9 -----------1.0
15.4---------- 20
24 ------------30
32 ------------42
50.1 ----------66
88.2 ----------117
143.2 --------190
362.1 --------430
I suspect that the scaling is off because, first, I had to scale the RC1200 injectors to 1270 to prevent the car from running rich at idle, second, I'm hitting very high load numbers, more than 360 although max boost was around 27PSI only. The car is 2.3L Gen2 GTX3576, ported head & intake manifold is expected to hit high loads but not by that much.
I'd appreciate your feedback
