First hello to everyone and happy holidays.

I had the 30K service done today and they installed new plugs from Kevin and forged DVs (also from UMW) I did not reflash to stock before taking it in...and also told them it had been reflashed. It is showing 1.0 to 1.1 boost (it's 30 degrees in Ohio) I often saw 1.1 to 1.2 before. I just drove it home so maybe on another day it will be the same but:

1 should I have flashed to stock before I took it in?

2 should I reflash my UMW tune again? could they have changed something that a reflash would correct?

car is 04 X50 tiptronic, europipe 2 quiet, UMW flash, Forged DVs, engine otherwise stock Thanks all

Drive it in various conditions and see how it feels.

If they had 'stocked' it, I think you'd see much lower boosts.

(editorial comment: I'd never go to any shop, dealer or not, that I couldn't trust to just do what I ask- nothing more, nothing less.)

Stock wastegates?

Yes stock wastegates...and I'm sure it's not "stocked"...I just wondered if they "tuned" anything or adjusted anything that might alter the UMW tune...thanks

Dublin, a quick way to tell if someone reflashed your ECU is to insert the programming unit into your OBD2 port and reflash your stock file. If it loads you are in the clear.

Thanks Kevin

What does this mean Kevin?

What does "loads" mean? If the UMW programmer inserts the stock file onto the DME?

I thought the programmer jsut overrides whatever is on the DME....

confused, sorry

Adam

PS Dublin- If you have K24s (x50) the upgrades wastegate springs will hold your boost better...

ard, if the ECU has been tampered with, or a new software revision reflashed. The programming unit will produce a error code. Similar to if someone was to take "your" programming unit and try to flash another car.

The bottom line is, I wanted to see if a error code is produced. The programmer doesn't over-ride, it will only re-write if the code and CRC is correct. If correct it will re-write to the ECU. Your valet file is a different file from your pump gas performance file.

My suggestion to Dublin was for him to quickly load a file, valet or stock or even reloading the performance file. If he produced a error code (blinking red LED) it would tell me that his software was "reflashed"

Thanks.


Sounds like if Porsche overwrites the code and recodes it to a new version of stock, that new version must get 're-modded' and placed in the UMW programmer prior to re-flash.

Well a couple weeks later and running beautiful...I know from my radio that they disconected the battery...ecu needed to relearn?...needs time to accept the new plugs DVs etc? Didn't reflash...didn't want to mess with perfection. Happy holidays

Sorry if I appear a bit dense....but why would the dealership reflash your DME during the 30K service? Is it because this is considered as a major milestone and part of the list of things they do....like read your DME files? If they read them and saw that they had been ....I think the term that displays is "altered" (per Loren's PIWIS read of my file with the UMW flash in it)...why would the dealership take it upon itself to mess with it? I've read the list of so-called service they perform, and most of it is visual inspection of belts, connections, hoses, clamps etc....they get a lot of money for "visual inspection" as opposed to actually performing services like changing plugs, running diagnostics on their PIWIS, oil and filter change, cabin filter (totally unnecessary if you ever roll your windows down??) etc. Lots of leader dot eyewash written up to make it look like a big deal and justify the God awful charge for the 30K service.

I'm sure that the dealerships routinely get cars in that have obviously had new exhaust systems, new DV's, CAIs, turbos, headers etc.....so they obviously know it's been "altered"....therefore why would they even attempt to revert the files? I dont' get it.

The version of the UMW flash I bought doesn't come with the OBD port plug-in device (yeah..cheapskate)....so if the dealership screwed with mine, I'd have to have UMW send me the OBD plug in, read the file, send it back, re-do the flash, send it back, and reinstall the file. That would tend to piss me off a bit. As long as you're not under warranty...Porsche shoulnd't care other than make a note in the service file of the "altered".

Kevin: as a side note...I know Adam has a UMW flash...why isn't he listed as a UMW customer? You know that he helped me set up your wastegate upgrade kit and he has it in his car too.....
