MAP Sensor and 94170715 Rom
I don't see 94170715 Rom listed as one of the Roms I can on both the JDM Sensor and Omni Sensor instructions. I noticed that there are subverisons of the 94170715, one specifically for the Omni, but not the JDM. What do I need to do? Do use the 94170715 for the Omni and copy all my existing maps/settings over (not sure if that's safe or possible)? Or do I just copy the xml info in there???
After reading through the threads and comparing the ROMs I have come to the conclusion to use these settings for the JDM MAP Sensor:
These settings for OMNI 4 Bar Sensor:
MAP Test 1: Mid VE High Voltage -- Change from 4.61 volts to 4.80 volts.
MAP Test 1: Mid VE Low Voltage -- Change from 0.10 volts to 0.06 volts.
MAP Test 2: Low VE Max Voltage -- Leave at 4.22 volts.
MAP Test 3: High VE Voltage -- Change from 1.8 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
3500 60
And "EGR MAP Offset #2" should read:
750 97
1000 86
1250 84
1500 67
1750 52
2000 56
2500 65
3000 63
3500 60
Change *both* tables to:
750 84
1000 84
1250 73
1500 65
1750 60
2000 55
2500 48
3000 43
3500 23
Change the "EGR Pressure Diff" from 0.12 to 0.04.
MAP Test 1: Mid VE Low Voltage -- Change from 0.10 volts to 0.06 volts.
MAP Test 2: Low VE Max Voltage -- Leave at 4.22 volts.

OK, I was trying to make the changes and had some additional questions:
On my ROM there is also MAP Test 2: Low VE Max Voltage. Am I supposed to change that to something or leave it alone (4.22 is what's on there)
Also MAP TEST 3: High VE Min Voltage-- it won't let me put in .5. Everytime I put in .5 or .50, it defaults to .51. Will this be ok?
Thanks!

With these exact settings put in, I am getting low vacuum readings at idle. I havent taken it out for a drive yet but it is showing -6-7 psi at idle when my gauge is showing closer to 14 or so. Any thoughts?
