I will probably be getting a EVOMSit ecu tune for my 997.2s, I am looking for input for those of you who have done this to your car. I know that doing this on a turbo gives significant gains which are very noticeable but I am hearing from a few guys without turbos that it is not worth the money to do on NA cars. So I just want to hear from those of you with NON-turbo's who have done this.

Also I have tubi exhaust with cross pipes and the BMC filters. So I am being told by the tuner that I should expect a 25 gain on hp and tq. But another tuner said they put this on their own car and only got 8 to 10 gains for just the ecu tune.

I am also being told that because it is a DFI engine you will feel more gains compared to the 08 and earlier models.

I am a mod virgin and thus very confused from the varying info.

Thanks in advance for your input.

 

I was thinking about the Softronic remap for my car. I dont know if they differ that much besides softronic being more user friendly.
I would be interested to hear what you think about the mod once you do it.

 

I have a 09 997S and thought about doing a ECU tune. Here are my thoughts and experience.

I did the Softronic ECU tune on my 07 997S and on the street I could not tell any difference. However I drive pretty normal on the street. I had Fabspeed mufflers and BMC air filter...not much in mods. At the track I thought I could feel a little more mid range and upper rpm power but none of this really turned into better lap times per say. It was really hard to tell if it was more power or a different throttle feel.

I will tell you this...I had my 09 997S in the dealer for a cracked header warranty last year. My dealer had to have the Porsche zone rep out to approve the warranty. The zone rep wanted to run a ECU diagnostic becuase he felt the ECU may have ben flashed and caused the crack due to higher exhaust temps. Yes Porsche was trying to get out of replacing the header which also has the cat on it for the 09's!!!! The dealer called me to ask if I flashed my ECU on my 09. Luckly it was stock and the Porsche rep could see this on the PIWIS tool.

My dealer is not far from me so I went down to the dealer and spoke with a service manager and met the zone rep. I asked about flashing the ECU and the Porsche zone rep and service manager told me the warranty is with Porsche not the dealership and if I flash the ECU with any aftermarket device my warranty on the engine and all electrical components will be void.

I urge you to call PCNA in Atlanta and ask them the question about flashing the ECU in a car under warranty.

 

Doesnt softronic allow you to re-flash the car to stock? so incase anything happens or you need to visit the dealership you simply reflash it to stock. Please corret me if im wrong.

 

You are right, but I have heard that if they want they can actually look at the full history of your ecu to see if you ever reflashed the original mapping. They say this is rare, also they say that if you have a good relationship with the service department they wont report it and will be cool about it. There are no gaurantee's so if the differnce is worth it then I will chance it.
Also a few tuners said that EVOMSit is much more aggresive then softtronics or REVO or others. One of the tuners that said that is not an EVOMS dealer so they can supply or order their parts.... so he has no motive to exaggerate.
And my tuner said they would reflash my car to orginal for free if it needed any warranty work.

 

hmmm, when you say Evomsit is more aggressive...how exactly?

 

ZoSo_DXB, Softronics can be flashed back to stock but Porsche can see if the ECU was ever flash by a aftermarket tuner.

I've heard of anything going wrong due to a flash on these forums...but I would like to know.

Zzzspeed, I do know that if something needs warranty work and the Porsche rep asks to run a ECU diagnostic the dealer can't hide or not report anything. Even if the car is flashed to stock they can still tell if it was ever flashed. They ran a ECU diagnotics trying to get out of paying for my cracked header/cat.

I truely believe that at 50% and less throttle that the DFI engine run very rich. I believe Porsche has tuned them this way inorder to pas some emissions. The DFi rich running engines produce a lot of soot. Above 50% throttle to full throttle the engines run leaner. I can tell this easily by the much cleaner exhaust tips...clean look to whitish grey.

I would like to know if any ECU tuner can safely tune the engine to run leaner under 50% throttle and run safely. I bet they can since DFI cylinder temps historically run cooler anyway. But the car can not run any leaner at 50% to full throttle.

If I was getting a ECU flash this is something I would put as #1 on my list to any ECU tuner. I would need to see proof and speak at length with them about.

 

Dont know what that means exactly, it is what I was told by a 2 different local dealers. I assumed it meant that it provides higher gains.

 

Mike (and others), my local dealer told me that even though the original flash can be re saved to the ECU, the dealer can still see that there has been some tampering with the program. He explained that it was much like seeing a saved date, but it had to do with hours on the computer, relative to the total hours. I waited until my OEM warranty expired before adding the Softronic. The flash makes things smoother, but I really didn't get the feeling that there was any extra power. Although I do like the extra 500 RPM added to the red line, and the fact that it got rid of my CEL from my Hi flow CATS.

 

Thanks you bring up good points. I will discuss with them some more. You are definitley more knowledegable about these things.
And will let you know what I find out.

 

Call Rhonda at FVD.

They did my 997.1 S set up for cat delete. Zero problems, pulls harder past 4K. They send you tuned file and original file.

I waited till my warranty was up.

 

This is probably one mod I'll never do.

1. Can't see it.
2. Can't feel it.
3. Voids Warranty.
4. Potential for CELs.
5. Lowers re-sale value.
6. Costs time and money.

To me, this is a no-brainer. JMO.

Your welcome...I would not say I'm more knowledgable, I just ask a lot of questions to the correct people and do research.

What most people do not understand is the cars warranty is with Porssche North America...not the dealer or the place selling the mod.


Ecu flashing on Turbo engines yeild a lot more of a benefit than a naturally asparated engine. After market mufflers and air intake on a Porsche really do not add much of any power.

 

Since I bought the complete FVD exhaust (Amazing BTW) I complimented their system with theie software and it is really sweet!!!! Sayboy did this great writeup and video of it.. He loves his too https://www.6speedonline.com/forums/...installed.html

 

Will someone please try a custom tune from powerchip? I keep hearing though the grapevine that they do magic but haven't actually seen any of their work.
