DIY On-Board Computer Upgrade Question
Hello all,
I just acquired a 1997 Boxster w/41,203 miles in what my local mechanic says is terrific shape. It is a completely base car - it has NONE of the options that were available for that first year. I am looking into the OBC upgrade. I have researched several of the "how-to"s, and ordered the parts, but before I begin, I have a question. In the digital portion of the tachometer, I already have a readout of external temperature. Does this mean that my OBC has already been enabled and I do not have to bring it in to the dealer to have it enabled? Any thoughts or guidance would be greatly appreciated. Fulcrum (new to the Boxster APR 2008) |
I don't thinks so, the outside temp display is standard.

The Outside temp display on the tach isnt standard, If you see it, then that means someone has already activated your OBC, you just need to install the 4th stalk or do the OBC button hack to toggle between the other readouts.

+1 for CJ being right... my 2000 S didn't display the outside temperature until Loren enabled it with his PST2.

DIY OBC Follow-up question
Thanks to all for the response. I was wondering if anybody had an opinion as to whether or not using the two switches on the dash is the way to go, or would it be better to install the stalk. (NOTE: The computer control stalk would be my third stalk - I don't have a cruise control....)
|
The second switch is only useful if you want speed gonging and to be able to scroll through the menu backward. (You don't need either of these features.)
Speed gonging is probably the most useless thing Porsche has ever thought of. It allows you to set a speed, then when you reach it the car will beep. You don't need it, and it isn't worth the extra $35 for the second switch. Also, I don't think you can get the OBC stalk without getting the cruise control stalk too even if you can't hook it up to anything. :cheers: |
DIY Guide?
My car has had the upgrade as I have the outside temp display. Is there a DIY guide to installing the switch to step through the OBC?
Thanks |
If you go with the stalk then buy the 4 stalk switch assembly and cut off the cruise control stalk. The 4 stalk assembly is cheaper than a 3 stalk assembly for some reason.
|
I disagree, I find the speed gong useful. I set it for 40 mph and find the ding helpful within the city limits when the speed limit is usually 35 mph. Regardless, some find the 4th stalk in their way when they track their boxster. I don't, so I decided in favor of the fourth stalk. If you decide to get the stalk version, buy all four stalks and then remove the cruise control stalk. It is cheaper than just buying 3 stalks without cruise.

Thanks Fulcrum
Thanks Fulcrum. Do you know exactly where on this site it is?
Cheers |
Found it
I found it. If anyone else is interetsed here it is.
http://www.pelicanparts.com/techarticles/box_OBD_Mod/box_obd_mod.htm Thanks guys. |
I used this guide and it worked fine (my OBC was also mysteriously enabled when I got the car, which was nice).
http://www.whiteson.org/boxster/mods/obc/ Despite spending time and effort doing the mod (not to mention the ridiculously priced switch I bought from my local dealer), I only really use the temperature display now.. :o |
Awesome mod guys. Something interesting. When I got my 99 Boxster it did not display the outside temp. I did not know yet that it was capable of that so didn't bother me. Anyhow, one day, I left my parking lights on for about 10 hours. Obviously the car did not want to start so I got a buddy to give me a jump.
As I was driving back home, I noticed that the outside temp was now displaying. Weird huh? Anybody have an explanation to that? Regards, Fred Larracuente Guaynabo, PR USA |
In my '97 it doesn't display the outside temp, but that would be pretty sweet. Thanks for all the good guides on how to hack it. I just may look into it, if I can rack up the nerve to open the Porsche up. (it will be my first time with any Porsche).
Any good tips I should know before I take the plunge? |
