I see that APR has a no ECU removal tune and now Cobb, according to https://rennlist.com/forums/718-for...-accessport-flashing-without-ecu-removal.html , has it too. $1100 for APR but the Cobb site still mentions an ECU removal is required.

Since these are removable, it shouldn't affect your warranty, right? Since you can swap it before you take it to the dealer?

I'd love to have 50+ more HP but since I have 4 years on my warranty, I don't want to screw myself.

From what I was given to understand, it would still be detectable that the ECU was modified.
In other words it is not a full OE restoration.

All ECU modifications can be traced by Porsche. In other words, even if the ECU is flashed back to stock tune, the fact that the ECU was modified is traceable.

Look, there is no away around all of this. There is no way to 'hide' an aftermarket ECU tune. If you are worried about your warranty, then do not get an aftermarket ECU tune.

Yes there is one way - kind of, get the tune from Ehresmann and you can get a new ECU.
Then you can swop when needed.

But it aint cheap, i cant remember the exact number - 1200 Eur for the ECU and around 2000 Eur for the tune.
You can find all the info on his Facebook page.

We're all big guys here. And if you own a 718 you have some money. Why should Porsche stand behind a warranty when someone boosts power? They shouldn't. I was really excited about the APR tune, but am concerned about the stoutness of my 6 speed manual transmission. My plan in six months is to get a detuned APR map (they offered to do it) for Sport mode (and leave Base and Sport Plus as mapped by APR)

From what I read those that are tuning in the 430hp are the ones having problems with the manual transmission, it's 3rd that goes. It's also been said that bad driving habits can also be a big part of it.

So if you own a 2.0 or 2.5S the power on the APR will be 400whp or less. You should be safe

I have the APR 400whp tune on my 718S with PDK she really moves now.

The gearbox has had a revision due to problems. Is it possible to link your source?

^^^ Cupra, you made my day! Ooo la la!!!!

 

[BB718]

I have read all this in the last 6 months, somewhat hard to go back and find just 1 link

But the 3rd gear problem is nothing new, go to Google and type in Boxster Cayman 3rd gear problem. Tons of information will just pop up. This problem has been found in stock cars (no tune). The issue for those under warranty or not is replacing the trans here in the USA, if not in stock how long do you have to wait to get one from Germany? Some have gotten them from salvage cars

On the tune side, some have de-tuned to 400hp in order not to have problems. I have even read that once you go over 430hp you start having fuel problems, new injectors have to be installed. The other problem is heat, the 3rd radiator must be installed.

My understanding is the APR has gone thru the cars really well, the tune is made to be safe and reliable. They had all 3 cars at the same time base, S & GTS. I even think they had the 911 too

 

[CupraLeon]

Here is why I posted the technical info(it's basically the same gearbox for the 981/982gen) the problem often occured during a downshift from 4th to 3rd gear, the third gear cog was splined on the older gearboxes, now its welded, so anyone with a 2016/2017 model should indeed be aware of this(or ask the dealer/or look yourself what code gearbox you have, the updated gearboxes have an x code in the end I believe), for people with later models there is no problem getting more than 400 -it's the torque you need to be carefull with. Indeed fueling is the limiting factor, fuel pump and injectors. Heat soak is due to the mid engine config

The other unknown with MT cars is how much extra hp/tq the clutch will take.
Personally, I've decided not to be an early adopter with this, I'll revisit the idea in a couple of years.

 

[tfcoll]

I have the 2.0 pdk base motor. Also, a newbie so forgive my ignorance, does the extra 50 hp really make a big difference?

Have a look at this video (german) Watch the 100to200kph time before and after tune. It's on a GTS ,but similar gain +-50hp (the dyno printouts are also shown in video)

 

[GregW]

If you look at the Car and Driver times for the base vs the S you will see that the increased power is hardly noticeable below 60 mph. IIRC the difference is about .2 seconds 0-60.

 

[cipher]

Don’t forget the base is a little lighter than the S, not much but some.

I contacted one of the biggest providers of this equipment and the sales rep said flat out, he would not recommend using their product on a turbo-charged 718. He said turbo heat was a potential problem and "until these cars have been around a while and second-hand owners have installed ECU units with success," he would not go that route - especially since I paid for an extended warranty - which would probably be voided if anything went wrong. I was bummed because I SO want another 50 HP!

Who was the provider?

 

[johan]

Who was the provider?

I talk with Jens Ehresmann about the same issue.
Thats one of the reasons for them to not tune above 450hp, track cars not above 430hp
At the same time the engine down tune it self when i senses that turbo temps are getting to high.
According to Ehresmann

I have tuned my manual GTS up to stage 2 (app. 450 hp and 550nm) and tracking it hard on Nurnburgring and other tracks, without any problems.
I have been running it tuned for 18000 km, so i think the risk for the gearbox to blow or any other problems to arise is overrated

Thanks for that info.
That's good to know
