Being an old-school air-cooled P-car guy, I really miss oil temp and pressure in my new (to me) 2009 Cayman S.

The 987.2 cars use the Siemens ECU which apparently supplies real CAN messages.

In reading AiM's information, it appears that coolant temp, oil temp and oil pressure channels are all available:

Code:
ECU_9     SM_ECT     Engine coolant temperature
ECU_10    SM_OIL_T   Oil temperature
ECU_11    SM_OIL_P   Oil pressure
However, I've read that a proper oil pressure sender isn't installed on our cars -- just a low pressure switch. Can someone confirm that this is correct?

By the way, the AiM data is here: http://www.aim-sportline.com/downlo...7-987MK2OBDII+EMS_SDI-3.1_Siemens_104_eng.pdf

Thanks,

John

I believe you need to install a 911 dual sender ( and a gauge for good luck ) and run a wire to the ECU for oil pressure. Oil temperature comes from the existing oil level/temp sensor.

Thanks Rob.

Do you mean a pressure sender that has a regular variable pressure output as well as a low pressure warning output?

Any ideas on where/how to connect the variable output to the ECU?

John, he is referring to part number 996-606-203-02. It has two terminal spades instead of the one on our current oil pressure sender. The "extra" one would connect to a gage.

Thank you very much, sir! That confirms what I was hoping. It would appear that the 987.2's (at least the S and R) have a real oil pressure sender and not just a switch.

It looks like the AIM information confirms that.

I'm not planning on tracking the car so an AIM system is probably overkill. I bought a couple of OBDII/CAN bluetooth readers and we'll see whether I can get oil temp/pressure on my phone before I go further.

Can you get the AIM Solo DL with CAN bus to show real time oil pressure and temp? Or only on a tracing when you download the data?

Did this ever work for you?

Aim canbus data definitely shows real time oil pressure and temp. I've used it for over a year now in my Cayman.

Thanks for the response! Is it an easy plug and play or is it hardwired?

An old thread but...
Do you know the CAN PID for the oil pressure message, and how the data is formatted?
And whether its the same on a 987.1?

Jon.


It is hard wired. Tapped into the 2 canbus wires.
