log boost with JDM MAP sensor (updated instructions)
i just t'd into the FPR line, no need to drilling the mani.. 
the logging from evoscan just requires it to be wired up correctly, you don't need to worry about setting the ECU up for it

the nice thing about logging MUT38 (MAP sensor) is you don't need to change anything in the ECU to get it to work.
so just wire it up and then log MUT38 and it should just work.
if you want to use the MAP internally though then yes you will need to change stuff in the ECU

The JDM MAP sensor can log as high as 30-31 psi of boost while the GM tops out closer to 28 psi, but the JDM MAP sensor has a funny shape that is not easy to adapt to a vacuum/boost line.
So do those WGDC numbers match your WGDC maps? What are you using for boost? Stock lines with upgraded pill or?
There is a max WGDC vs Coolant temp table. Looks like this:
20c - 0.0% WGDC
30c - 0.0% WGDC
40c - 0.0% WGDC
50c - 0.0% WGDC
60c - 50.0% WGDC
70c - 100.0% WGDC
80c - 100.0% WGDC
82c - 100.0% WGDC
And a WGDC Limit table (Cold engine/ CEL) that looks like this:
63% WGDC
also a Max WGDC Correction table that looks like this:
0 TP - 0 correction
13 TP - 0 correction
25 TP - 0 correction
38 TP - 0 correction
50 TP - 0 correction
63 TP - 0 correction
75 TP - 0 correction
88 TP - 16 correction
100 TP - 16 correction

Tomorrow (Saturday) is the last day I can ship sensors until after I get back from vacation in about three weeks. Place your order today if you want one soon...
See these:

at least for showing differences between using a MBC and ecu-boost control.
The JDM MAP sensor is for logging boost OEM style or using it for psi-target ecu-boost control.

I NEED HELP
im trying to do this step to my map. i cant seem to get my egr pressure diff to 0.04 it wont let me raise or lower % in 1. it only go's from 12 to 6 to 0 and back to 6. i dont understand.
also one step says
Change *both* tables to:
750 84
1000 84
1250 73
1500 65
1750 60
2000 55
2500 48
3000 43
3500 23
well i cant find *both* where is it???
i have an 03 evo and i am useing the right internal ID - 94170008
here is what it says on page one.
MAP Test 1: Mid VE High Voltage Test -- Change from 4.61 volts to 4.90 volts.
MAP Test 1: Mid VE Low Voltage Test -- Change from 0.10 volts to 0.06 volts.
MAP Test 3: High VE Voltage Test -- Change from 1.80 volts to 0.51 volts.
"EGR MAP Offset #1" should read:
750 97
1000 86
1250 75
1500 67
1750 52
2000 56
2500 65
3000 63

Change the "EGR Pressure Diff" from 0.12 to 0.04.
If you wish to disable the EGR test, change the ECU Periphery2 parameter from EFDF to EDDF. (Type 0xEDDF.)

also one more thing.
buy doing this step here

will that stop the CEL light from popping up??
i keep getting a P1400 code.
