Also found 0x381114 is the correct memory address to use. so far my entry is:
FPRESSURE, {Fuel Pressure} , 0x381114, 2, 0x0000, {WBAFR} , 0, 0, ?, ?, {logging Fuel Pressure}
Need someone to help fill in the question marks
Edit:
I think I have figured it out.
I started by figuring out the value at 0v and 5v (which the sensor cannot give since it is .5 to 4.5, but it is linear 0-5 so that is fine).
So I threw it into excel since its just fast to plug in and drag, and got the bucket for each PSI (in .5 increments), which is:
0 -18.75
0.5 0
1 18.75
1.5 37.5
2 56.25
2.5 75
3 93.75
3.5 112.5
4 131.25
4.5 150
5 168.75
So then I could find out my factor:
168.75-(-18.75)=187.5
187.5/5=37.5
0.004883*37.5= 0.1831125
and our offset is just simply 18.75 (we will make it positive because the ECU will turn it negative. So the final entry should be:
FPRESSURE, {Fuel Pressure} , 0x381114, 2, 0x0000, {WBAFR} , 0, 0, 0.1831125, 18.75, {logging Fuel Pressure}
Does this look right? I think i got it I will test it tomorrow.
