I'm still at a loss trying to confirm the formulas.

Here is how I gathered some info today.

I took my vacuum pump and used a t-fitting and attached the JDM map sensor to one end and the stock evo 8 map sensor to the other. I connected each sensor at atmospheric pressure and then applied the maximum vacuum my hand pump could manage to do (around -26.5inHG). I logged raw decimal values in evoscan for each.

Here were the results:

atmosphere
JDM= 76 [ 76*(4/3)= 101.33 kpa ]
Evo8= 242

full vacuum(capable with my hand pump)
JDM= 8 [ 8*(4/3)= 10.67 kpa ]
Evo8= 32

Now I'm just trying to make sense of the results.


I also found that the maximum reading on the evo8 sensor is 246. I need a better vacuum pump to find the minimum reading.
