Hey everyone, I was wondering if anyone had a list of the PCM Parameter Identification (PIDS). They define things such as RPM, Fuel Pressure, Air Temp, etc. I've seen a few posts mentioning them, but have not seen a list.

 

so you want the specs on the PIDS you listed?? If so give me a couple minutes and i will post'em up.

 

Compression pressure


Standard 830 kPa (8.5 kgf/cm2, 120 psi) [250 rpm]

Minimum 680 kPa (6.9 kgf/cm2, 98.6 psi) [250 rpm]
Standard difference in chambers:

Within 150 kPa (1.5 kgf/cm2, 21.8 psi)

Standard difference in rotors Within 100 kPa (1.0 kgf/cm2, 14.5 psi)

 

Oil pressure (reference value) [oil temperature: 100°C (212°F)] 350 kPa (3.57 kgf/cm2, 50.8 psi) [3,000 rpm]

 

Fuel line pressure 375 - 450 kPa {3.83 - 4.58 kgf/sq.cm, 54.4 - 65.2 psi}

Fuel hold pressure 200 kPa {2.0 kgf/sq.cm, 29 psi}

 

Initial-opening temperature 80 - 84°C (176 - 183°F)

Full-opening temperature 95°C (203°F)

 

how can i post pics in here?

 

The thing is, I just purchased an OBD-2 CAN SCAN tool from www.obdcscan.net. I am looking for Enhanced PID numbers (through a VB program, I would send a series of characters to the pcm...and receive data back. That's what I need.

 

give me a list of the PIDS you want and ill see what i can do.

 

I'd honestly like to see all PIDS...

-RPM
-Speed
-Current Gear
-Various Temps
-Tire Pressure
-Throttle Position
-Air/Fuel ratio

Those are to start with...

 

you want what you need the tool to send in order to get that info?

http://en.wikipedia.org/wiki/OBD-II_PIDs

if what you want inst ther (certain mazda specific pids) then you'll need to get chummy with hymee or sco. i dotn have that "depth" of info.

doesnt your scanner do this already? or is it just the mazda specific ones you need?

 

Yes, I need the codes to send the PCM to get the enhanced mazda specific pids.

I PM'd hymee but he hasn't been online for a few days.

 

goto the performance design australia website and email the contact from there. or try sco on pm here

I tried emailing, but kept getting bounced replies. I just pm'd sco though.

Thank you!

 

if you have a universal scan tool then you wont be able to receive mazda specific PIDS with it. You need a special scan tool for that(WDS). if you have that then there will be a listing of the PIDS availible stored in the scan tool for you to select from. If this isnt what your talking about then be more specific.

 

I do have a CANScan tool...that can in fact get the mazda specific PIDS...the problem is though I need to know what strings to send to the PCM to get the information.

 

cant you just call the company you bought it from?
