Porsche X51 ECU flash

[Mother]

Need to have car flashed with X51 software is this software available at the dealers and can be installed readily if requested for 2000 996.

All the fuel maps are stored on the PIWIS/PST2. You just select the map you want to program the DME with.

Jumped the gun again.... My bad.

The X51 map is on the PIWIS for DME7.8, but I can't see it listed for DME7.2.

Richard,

What is the source of those documents?

Thanks.

They where able to program it with X51 with Piwis and did not require authorization or any special codes and as far as I know I have a 7.2 ECU but will check when Durametric is hooked up next time?

You would need the DME programming code to change the fuel map. I did it on my Turbo, and you have to enter the code to access that part of the PIWIS program.

I did check on-line at PIWIS TSI, and it still shows the same fuel map list for DME7.2. I was surprised that it wasn't listed, as neither the X51 kit for 3.4's or 3.6's contains a replacement DME. The instructions I have for the 3.6 X51 kit show flashing the fuel map with PIWIS, and I would have thought it would be the same for 3.4's.

They came from POSES.

Unfortunately I missed them actually programming it, however I uploaded it to FVD for tuning of the map itself and will find out if any problems exsist. The software I use to install the modded maps is different using .XTT files and do not require PIWIS. My understanding is that there are two chips in the ECU that need to match to be programmed like a base map chip and fuel map chip and they need to talk to each other bad explanation I know but it's the best I have and should come with a disclaimer.

Curious with PIWIS, does it have the option for installing the X51 for the 3.4 engine.?

I guess it must do, if they installed the fuel map on yours, but the documentation doesn't say so. X51 maps aren't listed for DME5.2.2 (non-eGas) either. I think it must be an oversight in the manual.

The upgraded fuel map from FVD I installed over the X51 map worked fine with no problems and runs good except alternator not working crap :cursing: off comes the SC again.
