EMs SDU 3.2 Siemens

Cayman 981 GT4 Clubsport (this one resembles closest)

ProCoach

ECU Make: Porsche

IF you are connecting via OBDII cable, 991_981_OBDII

If you are connecting direct wire to the twisted pair, 991_911

Thank you for the info peter.

For now I'm goign w obd. I just tested it w wrong ecu setting (seiman - from previous car)

This worked for everything except brake pedal pressure and no engine temp.

I will change to obd ecu and try again. I am waiting for the direct connect wire to come so I will need to run this next weekend at COTA. It will be fine. I will report back in couple hours after I make changes


Another question - I have built in ext mic attached to the harness that goes from aim solo dl to camera. I guess aim camera picks up internal as well as ext sound. I just watched the test video and There was a lot of wind sound just driving on the freeway. I placed the ext mic in the sliding storage behind pass seat. I think sound gets recorded from int mic as well. Perhaps I can put the gain down on the camera setting. Suggestions?

I have the cables and can get you one for Tuesday if you want.

Go to Menu>Settings>Audio>Turn down the Internal to 0 and turn up the External to 50%

So, I want to confirm that your Race Studio 2 version is 2.56.00 in the top left (has the latest protocols for the configurations).

Then, create a Porsche 991_981_OBDII config with SmartyCam channels properly assigned, then "Transmit" to your Solo DL.

Then, plug in the OBDII connection to the car, turn on the key and with the laptop connected to the Solo DL, select Online in Race Studio 2 and verify brake pressure comes through when you hit the brakes. Car doesn't have to be running.

It didn't used to work, but I've heard it works now.

Thanks!

Peter - it is the latest version of RS 2 2.56.00

Reporting back w obd connection:

No brake pressure
No throttle
No engine oil temp.

Rpm, gps speed, water temp is working

I will create new profile and try again.

ProCoach

PPS (throttle pedal) should work...

I'm running a GT4 with AiM Solo and OBD connection. When you do the configuration, make sure to check the throttle position. There is no brake data available. The other issue I've had is getting the proper "Calculated Gear" to work. I can get Oil Temp, again, check configuration setup.

ProCoach

Gear from the ECU only comes through on PDK cars, not the street GT4.

I recommend Pedal Position, not Throttle Position (unless that doesn't work). Nannies show in Throttle Position, your actual foot and brain shows in Pedal Position.

Here is screen shot of my live data

Brake pressure = ERR for error. Throttle position works now.

maybe this is limitation of OBD? weird....

ProCoach

The car isn't running. Fire it up and see if anything changes from ERR to reading.

Yes, this is why every GT4 setup I have sold people uses CAN. It hasn't worked before (brake pressure, fuel level and oil temp) over OBDII.

991 GT3 and GT3 RS does, though...

Matt Romanowski

For gear, it's easy to add it to the automatic math channels when you open your data.

DC640

I have the can bus wire coming. I guessed that is the only way...

The software takes time to learn.. when u said math channels and such, i just lost u lol

ProCoach

Agreed.
