Hi,

We have a 2003 996 Turbo and we need a new NAV. BE6632 PCM 2 RDW is installed so I'd ask if BE6634 PCM 2 USA would be used for replacement. Anyone knows what is difference (maybe US map instead of Europe)?

Thanks in advance.

DME=Digitale Motor Elektronik=Control box. Cartography=by the manufacturer, adapted to the specific engine, programmed ignition, injection and many more contained inside the DME. The last manually adjustable flat 6 should be the "SC" series build in the seventies. I think that you probably meant the valve timing (crankshaft possition versus camshafts via timing chain), in this case i would, given the difficulty and risk, recommend a workshop manual.

Thanks for your help, it seems that somehow mechanic figured it out but just to confirm I will be pleased if someone can write firing order and cyclinder numbering.

Firing order 1−6−2−4−3−5

Cylinder order:

Facing the engine - back to front - left side 1-2-3

Facing the engine - back to front - right side 4-5-6

Thank you.

By the way, it seems that DME Control Unit is simply gone (RIP). so I'd ask if you know anyone that can supply used one at a reasonable cost as it is over $2000 brand new.

Best regards,

The ignition timing is not manually adjustable, it's all in the DME cartography.

Thanks for quick response but I couldn't find what a DME cartography is. As I have no knowledge about automobiles and mechanic has no knowledge of English ( what a combination), I will be pleased if you can explain what to do for crankshaft and piston positions preferably in "for dummies" level.

As my friend has a 2003 996 Turbo hit by flood, we had to clean every part. But the problem is mechanic had no need (!) to look at marks etc so he has no idea how to do ignition timing.

So I'd be pleased if anyone knows how to do ignition timing properly (and any picture, drawing etc is really appreciated)
