Vivid Racing is now offering 997TT ECU Programing from Softronic. I had never heard of them before but I guess they are the real thing. I got this from another forum (maybe Vivid posted it here too??):

By reflashing your Porsche 997TT, you will expect to gain 65hp and 85ft/lbs of torque to the crank. Softronic enhances the ECU functions to perform similar to the sport mode option on the vehicle. The ECU flash will alter the boost, fuel, and timing maps to gain these substantial differences. Vivid Racing has proved the performance of the Softronic compared to its competitors.

Softronic does not require the removal of your ECU from the car. There is no down time at all.
Softronic reflashing is done via a Client Cable (included in the price) that is connected to the OBDII port. The customer simply plugs the cable into the car and reads the file with a laptop per the instructions provided with the cable. Once the file is downloaded, it is emailed to the Softronic secure server where the file is manipulated and then emailed back to the client. The client simply uploads the file and they are done. Total process is about 1 hour during normal business hours. Other accomondations can be made.
If the client is not comfortable with the simple process, he/she can send the ECU to us to have it bench flashed. The client cable will not be shipped.
Reflashing is done according to additional modifications (Intake, Headers, Exhaust) to enhance power gains.
ECU Reflash alters boost, fuel, and timing (where applicable) maps for increased horsepower and torque.
Customer can upgrade to the Data Logging Client Cable which allows them to get real time data analysis with the Softronic Diagnostic Tool.

doesn't metion anything about permanently erasing type 2 over revs. all reputable tuners are now offering obd2 overwriting but not sure about erasing type 2 over revs.

the ecu should keep the number of times the ecu has been overwritten.

 

most likely true... I had two friends downshifting and breaking engines (1 E36 M3 and one 997S) and both got the stick from the dealers...

is erasing type 2 overreving a reality? can't do it from PIWIS can you?

now another issue correlated... has anyone felt a disappearing of the limiter and/or late entry of PSM with GIAC or other aftermarket reprograming?

 

The bearings are fried. It won't be long until you throw a rod. Just give it to me before the noises haunt you forever.

I think you have a good chance of being in the clear if you haven't noticed any issues yet. 7K doesn't seem all that high for these engines anyways.

 

okay...forgive me, but i've got a newbie p-car question. i've only had my car since late may.

i know everyone will most likely have a different opinion, but i want to throw it out there.

what rpm's do you usually shift at.....at each gear? this question if for daily driving. i have a 996 and a 986.

also, johnww, in the above thread mentioned that w/ other brands of cars, people downshift to slow down. what do you recommend for pcars? i really need to hit a driving school, but won't be able to until spring when they offer classes again.

any advice or info?

thank you in advance!

 

Like a lot of people say, brakes are usually much cheaper then replacing the clutch, so I recommend using the brakes to slow the car down unless you are on the track or something or just wanna play around down shifting every so often.

 

thanks mercedes benz

btw.....your gt3 is gorgeous. do you mind posting a pic or two? i'd love to see some closer shots.

 

Thank you. Check out this thread for some pics

Although i need to take new pictures since i do not even have those wheels on anymore. I changed to a set of HRE C20's in black.

 

This is probably an exaggeration. The 997 DME record over-revs differently than the 996. They are recorded as range 1 through range 6...no longer stage 1 versus stage 2.

When you over-rev from 6th to say 4th, the DME will record the number of ignitions the car spent at each stage. It will also record the time at which the last event occurred. Stephen or some other expert can probably correct me, but I'm pretty sure there are 350 ignitions per second. So PIWIS should show you the 350 X number of seconds the car spent at each range.

Most dealers will forgive a few brief over-revs for range 1 or 2. Excess or higher range over-revs indicate abuse.

 

I believe many of these Tuners are using Softronic for the port flashing from my understanding. Some are stating that they use it while others are not. Vivid seems to be using both mapping and flashing from their posts and Protomotive is at least using the flashing from other posts. FVD used to be listed their site also that I saw. PCA is data checking the race cars by them. There were some others that I saw listed on the web site however I cant remember exactly. I will check another forum and post to see what they have listed.

 

Well BoxsterGirlie, modern Porsche engines (boxer ones, ok) like to be reved, not overrev but to be kept in a high regimen of revs, anywhere above 3k to 6k rpms when daily driving. Do not slug the engine, they don't like that. Just drive it good ok, technical explanation too long.

On the downshifting, well, Turbos should be kept to a minimum, don't let the engine brake you, use the brakes and downshift at last point before the turn, heel and tow welcomed. Aspirated engines can work on downshifting but Porsches come with large brakes so you don't have to do it much, same principle as Turbos, brake and downshift until last point in the straight, heel and tow, and rev matching always, always good.

Tackle track activites from low to high and have an instructor with you, most Porsche Clubs offer drivers education... I started Mary at the Porsche Driving School

here with her instructor...

now she's a track junkie...


next year I'll have her jumping into the Boxster for faster laps, but this year I had her in the slow groups with her MINI mostly and sometimes she used an SLK350.

 

frissen,
thank you much for the info! i've done many autoX's and will be doing my DE this spring so i can drive the track.

i've not yet mastered the heel toe. i try to practice where/when i can. same with rev matching. i just need more prof. instruction.

that's very cool about mary! too bad you guys weren't from the seattle area! we need some more lady drivers!

thanks again for the pictures and the advice. i appreciate it!

 

FWIW BoxterGirlie, the idea that you should use the motor to slow the car dates back to when car brakes were really not good enough for the power and weight the cars had, say the mid 1930's or so. Engine braking continued to be a good idea into the mid 1950's. By the mid 60's (assuming dry weather) pretty much all race cars had brakes that would be reasonably effective through a race.

At this point I can't see how it makes any sense at all. It's not just that brakes are cheaper than your transmission and engine, it's that they work better to slow the car down.

 

no worries! everyone is making a large deal out of this but most engines are tested WELL over the rev limit. I have a rotary engine which can handle high revs but the red line is around 9.5k. My engine is tested to withstand 13-14k rpm revs. I dont know much about a porsches engine limits but since my engine is rated for 147% of its redline i would expect the same. (i guessed your redline is 6.5k?) so you should be rated somewhere around 9.5k rpms. if im terribly wrong someone please correct me but the OP should be fine!

No Problems!

 

Rotaries (which I am a fan of) are pretty different animals. They have no valves to bend.

A stock 12a will oil starve the concentric shaft around 12 -13,000 rpm at heavy load. It makes a bad noise.
