log boost with JDM MAP sensor (updated instructions)
#511
Background
USDMEVO9SE w/ 88590015 (dumped rom from car, stock).
ECUFLASH V1.35
Followed the instructions in the first post but I'm running into problems with some of the values not being exactly correct.
For example my MAP scaling value stock is
0.84,11
1.37,20
1.90,31
2.43,40
2.96,48
3.49,57
4.02,67
4.55,80
5.00,255
While the instructions says it's supposed to be
I tried changing it to the JDM values
but for some reason, some of the numbers get rounded up and it ends up like below
0.51,20
0.90,40
1.29,57
1.69,78 (I typed in 1.68 but it changed it to 1.69)
2.08,97 (I typed in 2.07 but it changed it to 2.08)
2.45,117 (I typed in 2.46 but it changed it to 2.45)
2.84,138 (I typed in 2.85 but it changed it to 2.84)
3.24,158
3.63,255
Moreover,
When I enter the value 1.46, it actually sets it to 1.45.
Everything else entered fine though. Would these slight changes cause any problems? Anybody else run into this problem?

Im pretty new to all this but have been playing around with the hex file, can anyone have a look at this and tell me if it is correct, the car is a JDM VII 98640014, the values for the EGR MAP CHECK 1 & 2 don't need to be changed in this revision i think.
anyway this is what I have come up with, do I just follow all other values when changing to the 3bar JDM sensor?
