How do i setup my PIDs to log?

[RyanU]

I have autometer 2246 transducers, wiring harnesses and plugs. ill be using these to monitor drive pressure boost and boost pressure. what are the steps i need to take to logs these and log them in psi?

[joecar]

Is the output range of your transducers 0V to 5V...?

Can you provide some psi/kPa sample points for various voltages in this range...?
0V == what psi
5V == what psi
Is the output linear wrt pressure...?

You provide 5V power/ground to power the transducer (I assume);
you connect the transducer output/ground to the FlashScan input/ground;

From the voltage/psi relation, we can make a calculated pid for this.

Depending on you car year/model, if you delete the EGR you can use the EGR circuit and the EGR voltage pid.

Do you have FlashScan V1 (LEDs only) or FlashScan V2 (LCD and LEDS)...?

ok i have them showing up in the pids i now need a PRN number for my second input.

i have both a v1 and a v2 ill be most likely using the v1 on my truck

the voltage on it is like what others had in other posts i think its .5-4.5

i have attached my calc_pids file for you all to see what else i need to do

also when the PIDs show up they say they are invalid, however i do not have them hooked up yet. does that make a difference?

[TAQuickness]

When a PID shows as invalid, right click it and select "more info..." The resulting dialog will tell you whats missing.

this is what i see

Boost Pressu {CALC.BP}

Expression:
PSI = ({EXT.AD2}*25)-12.5
is NOT valid because:
Required parameter {EXT.AD2}, at position 11 is not selected.

PID value cannot be determined because
the following error would occur:
Expression not valid: Required parameter {EXT.AD2}, at position 11 is not selected.

[RyanU]

this is the other one

Drive Pressure {CALC.DP}

Expression:
PSI = ({EXT.AD1}*25)-12.5
is NOT valid because:
Required parameter {EXT.AD1}, at position 11 is not selected.

PID value cannot be determined because
the following error would occur:
Expression not valid: Required parameter {EXT.AD1}, at position 11 is not selected.

In the scantool, under the PIDs tab, select EXT.AD1 and EXT.AD2.

[RyanU]

what about a PRN number for my second sensor how do i figure out what i can use? can i just got with F007 or is the something somewhere that i get this number from

[joecar]

Yes, change the second F006 to F007.

(I usually make the Fxxx number the same as the xxx in CLC-00-xxx).

And change PSI to lowercase psi (in 4 places).
