New DME/ECU


Recommended Posts

Do you get the I-Pass Codes from a Porsche Dealer when you buy a new DME/ECU p# 996-618-606-01 so you can program that unit or do they program it with your vin number and mileage when you go and pick it up at the dealer ?

Want to have a second DME so I can put a tune on my car ,don't want to mess with the DME that in the car now. That's why I want a second DME.

When replacing a DME you transfer the codes from the old DME to the new DME.

I think you can program one DME take it out of the car and program another - obviously one in the car at a time.

Do you want to have one with a tuned program and one without?

Yes..

So I have my Ipass Codes from the dealer so I transfer the Dme programing code and the immobilizer code to the new unit. What about the mileage for the car?

If I buy a used DME same thing ?

One with tune, second to pass inspection .

The current mileage transfers with the programming - it can not be altered using the PST2 or PIWIS.

If you buy a used DME then I believe when you transfer your program using the PST2 or PIWIS you do not change the mileage in the used DME. I'm pretty sure that you can only transfer mileage when the DME has never been programmed (new). At least that is what I recall...

Loren:

On page two it says 3. The data record can be changed, e.g. from RoW to OBDII ?

Is this talking about the seven rows of data that the car uses to run correctly and that tuners use to change timing ,boost, ect, ect

So my car with 4 O2 sensors should be set on ODBII ?

Not RoW.

Yes, a US car would be configured to the EPA's OBD II. To turn off the second set of sensors, you would change it to RoW. You cannot change the emissions program without access to a PIWIS or PST II unit, nothing else will reprogram the car to RoW configurations.
