As the 6speed contact for Softronic, I want to back up this post. We have had many SATISFIED customers with the Softronic ECU Flash. I actually have a 997C4s here that we are doing the AFTER dyno to show the results of. If you have seen my video and instructions of the Softronic flash, http://www.vividracing.com/catalog/e...4348_5027.html, you will know it is very very user friendly. You do not have to go to a tuning center and this can all be done in the convenience of your home or office. Like Scott does discuss, compared to other softwares, he goes in and changes actual tables, not doing global changes. When you flash your car with Softronic, you will notice that the throttle response is much quicker, the top end does not die off and keeps pulling, and there is a good improvement in the mid range.

As far as not being able to detect the flash. Softronic gives you both the modified and stock map for your car. So you can switch at anytime. Having flashed my own 997TT and connected it to a PIWIS, the PIWIS does show the ECU has been flashed, but it does not show how, why, who, what or anything. For all they know, it could be a dealer update. Nothing says on the PIWIS, "Modified ECU". It shows there was a read to the ECU. Unless your engine physically blows up, and all tuners will agree with us, there is no need to flash back to stock. Checking for a window regulator or a rattle will not throw off a red flag to the dealer.

Happy flashing!

Will a date stamp appear as to when it was flashed? The reason I ask is because I purchased my car as a CPO and if the DME doesn't show any kind of date associated with the flash, you can flash it back and forth a bunch of times and argue it was the previous owner who must of messed with it. I've researched most of the flash programs, I will be going the Softronic route in the immediate future.

When flashed with Softronic there is no date stamp increment in programming or anything different other than the power. When flashed to the original file the DME is just that, Original.

Softronic checks binary for several race organizations so we know exactly what to look for and any section of the DME that may get changed.

You can look at it as making a clone for a hard drive in a computer, everything on it is the same. Now of course the hard drive should also be the same size brand and model as the other.

Best,
Scott Slauson

Has anyone actually done an independent test to verify the gains on a NA car? Seems like a lot of money for a fairly minimal gain. I don't think I've seen any customers on here do a before and after dyno yet. I've had NA cars flashed before and it was barely perceptible. The only thing I noticed is that the thottle travel felt like it was electronically reduced.

I don't see many before / after dyno charts for most softtware flashes- But I think one of the primary benefits is supposed to be improvement of e-gas response, such as quicker pedal response etc. When I did my BMW's with the Dinan software, didn't pick up any HP but the car was much more responsive to pedal input and perkier in the mid-range, basically more "driveable" for those of us with the standard-issue leadfoot..

Keep in mind too that one of the biggest HP-limiting factors in Cali is our lower-octane gas.

What would be interesting to see is if there might be any gains to be had by modifiying the throttle gears inside the 997 throttlebody. Dinan produced a modified BMW throttle body for E46 cars that had a "faster" gear ratio, which provided an almost "cable like" throttle response. E-gas lag was pretty much gone. It worked very well in conjunction with their ECU flash.

I agree that dyno results would be nice, but I am convinced that the softronic flash really brought everything together on my c4s. Throttle response feels much improved and there are not hiccups in the power band. It feels more torquey and that is something I can feel everyday as opposed to top end horsepower which has limited application in the real world. Big fan of the softronic programming.

I have a 997C4S I am waiting to do the before and after results. The customer had to leave town for family, I will get it posted asap.

Any mods on the car, or is it a stock C4S?

The car has our Agency Power high flow exhaust system on it. The before and after will be conducted with that.

When ordering the Softronic Software it comes with a cable and software, is there a different price if the Softronic Dealer downloads the software for you? Also what happens to the original software if the dealer installs it?

My Cayenne has a sport mode that essentially adjusts the throttle sensitivity and shift points. There is a definite difference with it on and off (you can tell by holding the throttle steady and hitting the button), but I am not sure I would invest one or two thousand dollars to make the gas pedal snappier. You could save some money by just pressing a little further down and achieve the same effect

If a dealer installs it and you do not want the $150 client cable, the dealer will have your stock map and tuned map available to put on disk or email you. It is sent in a email form. So you can retain the rights and hold on to it. The only difference is the price of the client cable. However the convenience of the client cable and ability to flash the vehicle in your own time is well worth it. let me know and I will take care of you.

Cool, that is a similar set up to my car. Looking forward to the results.

So the software flash should be $150 less if the dealer does it, or do they charge the same?

Here's a question: I have a GIAC reflash with its $1100 sunk cost. It gave me a dyno verified 7 rear wheel horsepower over stock ECU programming. Can APR or Softronic do anything that is even remotely cost justified? Many of us have GIAC programming, as it was the hot setup a while ago. There is also EVO's new programming.
