996tt flash
Hi,
I recently tried to install new software on my car. The manufacturer is FVD. We worked on it for half a day one saturday and were not able to get it installed. The FVD tech said it was because my ECU already had software on it. They could not overwrite. So they wanted me to ship my ECU to Germany so they could install their software. It's not that I do not trust them, my issue is that, I am reluctant to spend 1600.00 on new software when I don't even know what the current software is doing. The performance gain may not be much or none at all. Any suggestions on how I could evaluate what I have now?

About all I can suggest is you do some benchmark performance measurements (dyno?) and then read up on what FVD software promises and see how your car's current performance with this unknown software present compares the what you want to move to.
There might be a way to query the current engine controller software for its manufacturer's name or id or something that someone in the flash/software business could use to tell you what's in the car.
There are standard (OBD2) queries (using mode or service number 9 and Infotypes 0, 1 and so on up to 7 or 8, though not all vehicles or their engine controllers support all let alone some of these. But the Turbo does, at least some of them.
Some of these are VIN; Calibration ID; Calibration Verification Numbers; In_Use Performance Tracking.
There are supposedly even more Porsche specific and proprietary data to be had with the right tool. The techs tell me that under certain conditions about '20' pages of data is read and sent to the factory when a car is brought in, mainly when it is brought in for warranty work/repairs.
Sincerely,
Macster.

What boost pressure (bar) are you getting on a 3 or 4th gear run?
If you have access to a Durametric, you can log a handful of values to get a good idea of what the tune is doing and if it looks ok...
I haven't seen anyone post of a way to determine what tune an ECU has, though.

Billbarnes, with the stock one you should be boosting at only .6 and since you're boosting at 1 bar it's definitely modified. Unless there's something wrong that you want to resolve with the re-flash you might want to check with FVD to see what you're getting (performance-wise) ... it's probably not worth the expense if you're only going to gain a boost of .1 after the re-flash.

), it seems that 0.8 is stock with most guys getting 0.7 to 0.9 in their cars.

Try 6th gear @ 3-4k wot. This will show your max boost as load will be highest. I have x50 flashed with exhaust. Result is peak 1.3 bar. No exhaust you should boost 1-1.1 bar. Stock is 0.7 so it seems you are on target. Unless you are going up on mods no point re-flashing.
