log boost with JDM MAP sensor (updated instructions)
One question, so is the only reason to use the 3 bar is because obviously for you guys the 1 bar is worthless? What I am getting at is I am driving a car only hitting 10psi, can I use the 1 bar map to log my boost then using this?

The 1 bar is only good to 2.2 psi of boost, so you'll need a 3 bar.

any idea ?
...
I worked in my evo. Conecting the signal of MAP sensor on #73 ECU pin, see nothing on EvoScan 2.5
Then, remove the ECU and open it, the terminal # 73 is not connected to any circuit.
Thinking and observing, the # 75 pin is locatd next to the # 76 (Lambda Signal) and the internal circuits, filters, resistors and transistors are very similar locatd. Next step, injected into the # 75 Pin 2.5Volts limited power to observe a variation of reading in Lambda # 2 on EVOSCAN. Finally I corrected The Request and Formula for MAP read .
Works well as datalog, but can cause changes in behavior of the ECU to change the input value of the 2nd Lambda signal? Even taking into account that does not own or EVO 6 wiring for the 2nd lambda sensor?
Easier, the value of the # 75 pin is taken into account in the programming of the ECU?
Thanks and cheers.

My MAPS is located on the TB.
Is this kind of MAPS 3bar JDM?
Thanks great post

From the factory 1 bar to the JDM/X 3 bar.. are they visually different at all? I bought a used evo that had a fair amount of tuning and work done to it, so I'm curious to know whether I have the factory or the JDM sensor, before I go hunting to buy one. Thanks if anyone has both and can inspect, or knows another way to tell.
