Log boost from Defi sensor on Evo 8 EDM


I don't have MAP sensor, so as the wiring. But I would like to log boost with EvoScan.
Can anyone help me with appropriate wiring and EvoScan settings to make it real?
I've already used 75 pin (rear O2) to log my AEM UEGO. Is there some more pins which can I use to log boost? Is 73 pin OK for this?

And another question, to setup normal MAP sensor, I would need either JDM/USDM intake manifold, or drill some holes in mine, right?

You can connect the Defi's linear boost output signal into the Evo8 4-plug ECU at pin 73 and log it on MUT38.
This will work for the Evo7 and Evo8.
With an Evo8 3-plug ECU, the MAP input is on pin 92, same as the Evo9.

I log my HDi 3.5 bar boost gauge the same method on my Evo9, except it is pin 92 on the Evo9.

To log correctly, you need a conversion equation in EvoScan to get it right.
This will be different for each brand of gauge/sensor.
So you will need to post up the supplied data for the boost signal.
