OBC (Onboard Computer) Hack

Charlie_McLaughlin · Apr 28, 2003

Having bought a 2nd hand C4, I was disappointed to find I didn' t have the OBC option, having had it on my previous 2 Boxsters. I had the Temp Gauge, which all C4s have but not the rest of the functions. Printed off from the Boxster Board
" www.986board.com" a hack, allowing all the functions of the OBC apart from the speed gong.

All I needed was to purchase a spare switch, some bits and pieces and follow the instructions - Sounds easy, however I am not so clever so a mechanic friend did the rest of the work. Works great, apart from now showing how poor my fuel consumption is.

Have you got any further information?

Note: Charlie seems to have got this working on a C4, it is however only worked out for a Boxster - it may not work on all 996 models!

If you' ve got enough time to play with the OBC you' re not driving it like you should.
Buy a DELL for home and drive the Porsche.

The Boxster hack is the same for 996' s. This is for pre 2001 model' s- as long as you have the temperture probe ( front right air intake in front bumper) you can get your OPC to activate the temperture function using PST2. After that a copy of the hack downloaded from www.986board.com is all you need to get it to work for you.

Does anybody have any experience of a UK OPC enabling the OBC with their PST2 ?

If so how much did they charge as I have just traded my BMW 740i with every gizmo you can think of for my 911 Cab and I miss knowing the outside temp etc.

Sorry I have been on holiday, any OPC worth its salt would do it for nothing !! It only requires a quick flick of the PST2, however you do need the temp probe, found in the right side grill, without it it will notwork.
