I know this has been spoken of before but I wanted to hear from people that have either had both or tried both.

1. Which chip results in better performance?

2. Which chip has better daily driving?

3. Are both chips detectable by the dealer?

4. Will both void my warranty?


Which is better in your opinion?

 

agree with my man from tampa above. All i can say is wow after i did mine in combination with my Tubi headers and mufflers. I would say Softronic is the way to go.

 

I am very happy with my APR.

It has some nice features versus Softronic like a security feature and switchable to different grades of gas.

Softronic says theirs automatically compensates for different grades of gas and is invisible to your favorite service department.

It pulled all the modifications I made together and I really like the way the power comes on with the ECU mod.

No regrets.

It would be nice if a magazine would do a comparison.

Frankly there are limits to what any ECU modification can do so IMO they are all probably very similar. I would love to be proven wrong on this hypothesis.

 

REVO allows you to "test drive" their ECU upgrade for 5 hours before buying. The authorized shop uploads the flash, you go try it, if you go past 5 hours it reverts to "normal" mode.
Has ability to switch back to your normal software if needed, for service etc.

But I have no idea how good it is, this is just what I read off their site. I thought the "try before you buy" thing was kinda cool.

 

The thing about the Revo trial is that after the trial is over, it will be detectable and leave a "footprint" on the ECU if checked for any warranty work.

 

So what? It would be pretty hard for Porsche to deny a claim on a blown engine because of software if they could not prove it was the cause. I frankly have never heard of the problem. It just seems to me that their is a certain amount of selling going on based on the "fear" of detection.

I would rather hear but never do that are software makes the car perform better because of....versus xyz brand.

In fact the owner of Audi dealer told me Audi would not deny it on one of their cars unless there were obvious signs of abuse. I am sure Porsche is similar.

Bottom line on the software issue to me;

Porsche detunes the cars slightly through software for liability reasons and lets the after market for the enthusiast fix it.

Lets face face it the stock set up is pretty lethargic up to about 4-5000 RPM then the car takes off.

What I have experienced with APR and sounds like I have heard from other brands is the car comes on the power band much sooner 2500-3000 RPM and just seamlessly goes from there.

 

What liability is Porsche trying to avoid?

 

People going too quickly and hurting themselves. My guess.

 

You don't need 30 more Hp to get hurt with these cars.

 

All tunes are detectable by a dealer. Of course you can flash it back to stock, but if they dig deep enough, they will be able to tell that you have had a tune.

If you blow an engine with a tune, you could have a tough time having Porsche cover it.

 

I have heard the same story of all software downloads being detectable by Porsche.

 

Guys trust me I can tell if something's been flashed with my tools so can Porsche The PIWIS can and does show _any_ modifications done to the code and they can see/tell how many times you've flashed the car.

Whilst flashing is indeed a neat way to get some more HP I always tell people up front that the dealer can indeed detect it if they want to.

 

I think we should clarify this once and for all. There seems to be many posts on what people think Porsche can detect or is considered altered. An original flash or a Porsche flashed back to original is just that, original, Period, all others are not. This would include flashes that switch as original etc. These do not re-program every time you quote switch them. These are still the same flash in the DME and are always altered.

The only thing that the PIWIS can show you is the CVN in which you would have to know what the number is to compare it. The other information in faults, vehicle data etc does not mean it is a correct file just because it can be read out. Porsche eliminated the Pass or fail section for the DME in the PIWIS for this specific reason. Should the binary in the 1 meg range be altered by flashing it can and always will be detectable.


So unless the DME is as it was when it was first made by the factory it is detectable.

Performance question- I notice on my 997 the throttle response is a bit sluggish to pedal input. I like it to be more "twitchy" and responsive. Blipping the pedal doesn't blip, more or less..

Would an ECU flash help with this?

 

Yes. The APR ECU upgrade on my car does. Call APR to confirm.
