OBC Hack

[rpastir]

Hello All,

I recently performed the 4 stalk OBC hack on my 2000 996. After getting everything installed and put back together, I found that I'm able to move through the different OBC menus by pushing down on the 4th stalk....however, when I push up on the 4th stalk I am not taken back to the previous menu. Is this operating normally?...or am I missing something?

Thanks-

Rob P.

Rob, for us tourist would you explain a 4 stalk OBC hack? OBC=on board computer?

For cars without the 4th stalk on the lower left of the steering wheel, there is a way to activate it and install the 4th stalk to let you see outside temp, avg mpg, avg speed, miles to empty and I think a speed gong to let you know when you're driving over a pre-set limit. You can also activate it and put a switch somewhere within reach that lets you scroll through the information screens.

Sorry I can't help the OP's question.

OK, I have the 4th stalk, however since my LS3 conversion that is the one feature that has gone south. I have all of the above with the exception of average MPG and miles left in the tank. Are you staying that all ECU's have that information and the only thing you have to do is to install the selector stalk?

creekman,

The typical hack only shows you how to connect to the existing wiring in the steering wheel & cluster. With your conversion and point-to-point custom wiring you had to do, it is difficult to say where it broke. However with some schematics, there should be a way to figure out how to reconnect to the data.

Actually, that only works with 2000 and earlier cars; if you activate the OBC in a 2001 and later using a PST II, PIWIS, or the Durametric Pro system, there will be no display until either the stalk or some other substitute switch is wired into the system, then the display will appear.
