Cannot confirm yet the validity of the PID on the previous post but have my own question:

Can I make a usable extended PID for torque from the following data?

parameter id=”P36″
name=”Primary Wastegate Duty Cycle”
desc=”” ecubyteindex=”12″ ecubit=”3″ address>0x000030
conversions
conversion units=”%” expr=”x*100/255″ format=”0.00″

Here are a few reference data from the same source for a couple of standard PIDs:

parameter id=”P8″
name=”Engine Speed”
desc=”” ecubyteindex=”8″ ecubit=”0″
address length=”2″>0x00000E
conversions
conversion units=”rpm” expr=”x/4″ format=”0″

parameter id=”P9″
name=”Vehicle Speed”
desc=”” ecubyteindex=”9″ ecubit=”7″
address>0x000010
conversions
conversion units=”kph” expr=”x” format=”0″
conversion units=”mph” expr=”x*0.621371192″ format=”0″

Thanks!

Knock Retard is available through Torque, and a wide range of vehicles appear to support the PIDs related to it.

However you *must* update to the latest version of Torque before doing anything else – this means getting the latest version that is currently available on the Android Market. Torque is only distributed on the Google Android Market.

Once you have upgraded to the latest version, use the menu button and go to Menu->Settings->(Scroll to the bottom)->Manage Extended PIDs.

Then use the menu button to *clear* anything that is present. This is important as the Torques implemented predefined PID lists have all recently changed.

Then Menu->Add predefined set. Be sure to read the dialog fully.

Most vehicles seem to support the GM PID set. You may try this set on any vehicle and it should make available extended PIDs which include Knock Retard, Cylinder misfire history, Injector Duty Cycles, etc.

How can i get injector duty cycle?

Bump please…..

Bump…. Seriously….. I really need injector duty cycle….. How do I get it? Please…..

0C05EC PID doesn’t get any data from my WRX ’06
GM PIDs neither.

Hi

I’m not ignoring this thread, I’m just really busy and this needs a proper explanation, I’ll try that now

If you have a GM vehicle, and the injector pulse width PID works, then you *should* be able to work out the duty cycle from that – this web page offers a conversion: http://www.stealth316.com/2-calc-idc.htm – you will need the RPM as well

This page may also be of use: http://ls1tech.com/forums/pcm-diagnostics-tuning/306296-conversion-injector-pulse-width-duty-cycle.html

The PID information for pulse width is:

  { "Injector Pulse Width",          "PW",            "221193",   "(((A<8)+B)/65.535)",   0,   100,    1,  "ms", "Auto"},

You may be able to alter it to do a direct realtime conversion to duty cycle, however I can’t vouch if it will work or be accurate. The equation you would need to use might be:

((((A<8)+B)/65.535) * [0C]) / 1200

which you could use instead of the current equation in the pulse width extended PID. the [0C] is the PID for RPM. This works, however I haven’t the time at the moment to test fully

I’m the one who emailed you about this… It works fine on my 2002 Chevy cavalier 2.2 Ecotec. Thanks man sorry for the bother.

thanks for sharing such a wonderful information

Moved file to the correct directory.
Opened Torque… then added predefined file and
the symbol was there!
Hope this helps.
