3.4 conversion, which DME

[smartrepair]

My 3.4 conversion project goes very slowly forward, I already have the engine block. Still searching for the intake manifold.

Does the 996 standard ECU (from year 1999) fit to my 1998 2.5 manual Boxter? In Spain I haven´t found anybody to reprogram the ECU, and found this unit which is for sale...

Thanks

The '99 996 and boxster used the same DME just programmed differently.

If you use your DME you will need to have it configured for the 996 engine. Pretty standard, remove it and ship it to someone to do this.

If you use the 996 DME you will have to have it matched to the driveblock computer in your car or it won't function. I am guessing this is a worldwide feature of the cars and not a north america specific thing. I think this can be done with a PST2. If the cars in Spain don't have driveblock then you could just swap in a non egas 3.4L DME.

My 98 Boxter is 98 US model, so it will have the driveblock.

How much are you paying for the reprogramming? Of course I could send the DME to the States...

[tholyoak]

Depending on who you go with, somewhere in the range of $1000-1500. This also gives you the ability to have the dme programmed to more aggressive settings for the same price.

I found a 996 DME, part 996 618 605 00.

Does this fit for the 3.4 conversion?

If I bring it to Porsche dealer to configure the driveblock, it will cost me total about $200, not $1000, apart that there´s nobody in Spain who seems to do the conversion on y standard Boxter DME.

[tholyoak]

No, that is a DME for an egas car. The DME you want is from a 996 but as stated above it is the same part as your boxster, that is 996 618 601 04. Since both cars have the same dme, I would assume the dealer should be able to program it with the PST either to the configuration for a 996 or a 986. If they won't, stick it in a box and ship it to one of the many places that will reprogram it. They are all over europe and north america.

Only MY98 and MY99 C2's are non-egas.

All MY00 and all C4's are egas.

[tholyoak]

Yep, and those are the engines you want to stick into a non-egas boxster, otherwise you will be looking for a non-egas 996 throttle body or converting your boxster to egas.
