DME setting after switching on OBC

[Diamondgeeza]

I have had the OBC switched on in my 03 Boxster S by my local dealer.

As you know on 03 Boxsters the hack to switch on the OBC involves first changing the 'Order type' setting in the DME.

I understand the DME is involved with engine control so is it important to set the order type back to it's original state once the OBC has been enabled.

I ask this question because since the dealer did the OBC switched on I have noticed a very slight reduction in performance.

Did Porsche have good reason to set the order type differently other than to stop OBC switch ons?

This could be just my paranoia or a coincidence as the weather has got a lot warmer recently.

The order type is not changed, it is missing from the DME on some 2003s. The very early 2003s had the order type in the DME. When the first 2003s showed up in 2002 Peter turned on several cars on the lot.

We did two 2003 reftrofits over a year ago, and Abe with a 2003 recently did his. No problems have been reported. Last year I went around the parking lot with Peter and the PST2 when the order type issue came up. Peter thought you could enter any 6 digits in order to change the cluster coding, like 123456.

Can't see how having the order type in or not in the DME can have anything to do with performance. The DME is also supposed to have the 4 digit radio code (pre 2003) in the DME but some cars do and others do not. Mine did not but I asked a friend with a PST2 to store it in the DME, and it has nothing to do with performance. Jeff

Thanks for the information.

The new OBC stalk and other parts are on order from Sunset Imports so I should be ready to start the retro-fit very soon.

I'll let you know how it works out.
