if there is a JDM map sensor in the car and the xml is not setup for it what are the effects?? i just noticed i lost my 0015 jdm setup and the car is going nuts. p1400 codes and just running poorly.
what are the effects??? and yes i am working on fixing it.

So just to be clear, the 96530006 rom doesn't need these tables below to run a different MAP sensor for ECU controlled boost via MAP signal other than the JDM map?? (These aren't the tables for that ROM ID, just to clarify what tables I'm actually looking for, for the 96530006 rom)
Code:
<table name="MAP Scaling" category="MAPSensor" address="57D2" type="2D" level="1" scaling="uint8"> <table name="MAP Output" address="6ED4" type="Y Axis" elements="9" scaling="Volts16"/> </table> <table name="MAP Fault Trig: Mid VE Max #1" category="MAPSensor" address="28B4" type="1D" level="1" scaling="Volts16"/> <table name="MAP Fault Trig: Mid VE Min #1" category="MAPSensor" address="2894" type="1D" level="1" scaling="Volts16"/> <table name="MAP Fault Trig High VE #1" category="MAPSensor" address="289A" type="1D" level="1" scaling="Volts16"/> <table name="MAP vs MAF Baro" category="MAPSensor" address="2802" type="1D" level="1" scaling="uint16"/> <table name="MAP Comparison" category="MAPSensor" address="27FE" type="1D" level="1" scaling="Volts16"/> <table name="ECU Periphery2" category="ECUPeriphery" address="fca" type="1D" level="1" scaling="Hex16"/> <table name="ECU Periphery4" category="ECUPeriphery" address="FEA" type="1D" level="1" scaling="Hex16"/>

I don't want to just 'log' the sensor, I need it for PSI based ECU boost control and need it to be dialed in so when I put 22psi in my tables(plus boost adder of course 
), it KNOWS when its at 22psi. Is anyone using 96530006 for PSI base ECU boost control with a non mitsu map sensor? Wouldn't we also need that for SD too?

This setup will work for some of the addresses for a EDM 17?
I have a JDM manifold installed with a JDM and IAT sensor in.
I just made the connection to the ECU for booth sensors.
JDM 3 BAR MAP
Pin 1 from the sensor to Pin 92 (signal) from the ECU
Pin 2 from the sensor to Pin 49 (power) from the ECU
Pin 3 from the sensor to Pin 42 (ground) from the ECU
For the IAT
Signal wire to pin 96
Ground wire I tap pit under the dash to a ground point.
Something was wrong after I connect the sensors....
First I get some trounble codes:
P0120: Throttle/Pedal Position Sensor/Switch A Circuit Malfunction
P0107 - Manifold Absolute Pressure/Barometric Pressure Circuit Low Input
Now if the MAP sensor signal is low the car will likely have a very difficult time to start right?
The problem is that the car idle remain at 1700 RPM without moving and I have a problem like a boost cut when I try to go higher than 3000 RPM`s.
I think I must check the signal from the MAP sensor but my question is how?
I want to test all the circuit from the ECU to the Sensor to see if I have 5 Volts on the reference circuit.
How can I test the resistor that moves in relation to manifold pressure? I wanna test if the resistor voltage varies between about 1 volt to 4.5 volts to see if the MAP is good or not.....

I have check again the wires and seems that I did a mistake when I split them.
So the wires are connected like fallows:
Pin1 = signal (92 pin)
Pin2 = ground (49 pin)
Pin3 = 5V reference(42 pin)

Pin3 = 5V reference(42 pin)

The sensor seems that is working now.
In order to get a value close to 0 without starting the engine I change the formula in Evoscan with 0.19347*x-13.35 but my actual local atmospheric pressure altitude is 200 meters above see level.
Seems that my IDLE stays a bit more high for a period of time until in going at the right position...
