ECU tune a 718 2.0ltr?
Discussion

With a ~20% increase in power and torque from a simple remap done by merely plugging a laptop into the OBD2 port it seems to me that you can turn a bass Cayman into something that has the performance of a 911Turbo from 15 years ago. That’s quite some progress,
When 718s dip below £30k and are no longer warrantyable I might be interested in pursuing this avenue.

On a new car warranty Porsche would need to prove that your re-map caused an engine issue, if you had one. I don't think that would be too difficult for them, probably stating the engine was operating outside of their testing tolerances etc.
You'd also put your car at risk of never being eligible for an extended Porsche warranty as an ECU check would show the current, or previous re-map. Resale would be affected if that's the case.
I'd only do it on a car that was a keeper, or had some other reason why an extended warranty wasn't possible e.g. second hand car bought cheap with existing mods etc. Otherwise you're throwing money down the toilet for the sake of a few BHP.

Nodding and improving your Porsche is a big part of the culture in many markets including Germany. The U.K. seems a bit anal in keeping everything standard and focusing on building the perfect spec and options combo.
Given that a two seat sports car is a pure leisure item and not an investment vehicle I have no hesitation in customising and improving mine.

I never bother with warranties and as a source of fun/enjoyment I don’t particularly care about maxing the residuals. If I did then I’d leave the money invested rather than spend it on a two seat penis extension.
I’m partially out of Porsche ownership in the U.K. because the scene seems to be full of types that don’t actually love driving but spend inordinate amounts of attention on the minutiae of spec, finish, polish, finance, residuals, trim and image. The numbers of Porsche buyers who actually want to beast the car and give it a damn good thrashing on a regular basis just for the fun of doing so seems small.

Respect.
So what that video doesn't tell you is a lot of things.
They make it sound so simple - just flash the port, remote tuning and so on. It isn't.
Firstly on the latest 991.2/718 platforms the ODB Port is blocked. You cannot plug a cable in. They mention 'unlock' in the video - what that means is that you can only use the ODB Port after the port is unlocked. To do that you have to remove the ECU, open it up, then run a special program to unlock the ODB. Then you can use a device such as my genius etc to read and write to the ECU. So why is that important? Because let's say you want to return to stock before a visit to OPC - well then it will be open and visible, or if it is done as we do, you create the base program copy before unlocking, but then it will need to be unlocked again after your visit. So not as simple as it suggests.

I wouldn’t be using an OPC or trying to conceal the remap.

Nick Murray seemed to get the best part of a $70,000 more expensive Turbo out of his remap...
Hell even Ford is running 17Psi turbocharges these days on their mass produced lumps.

I'm not talking about maxing residuals, I'm talking about making your car worth substantially less than a standard one. You may even find dealers won't buy the car if they know the ECU has been messed with.
You may not care about losing £000s, but others might.
Couldn’t agree more Twinfan. Buy a £50k plus car and then throw away the warranty and residual value? Nuts - to me anyway. All this is telling me is this kind of meddling simply means the owner has bought the wrong car in the first place.You may not care about losing £000s, but others might.

Am Anfang schaute ich mich um, konnte aber den Wagen, von dem ich träumte, nicht finden. Also beschloss ich, ihn mir selber zu bauen Quote: 'Ferry' Porsche

Frankly, that's rubbish - ECU tuning is a tried and tested method of safely increasing power these days.

The OEM end of automotive industry is strangled by legislation to meet emission, noise... regs. Internally the finance dept limits much of the engineers potential. In the UK you may be correct in that much of the aftermarket world is completely unregulated and anything goes however most looking to modify, will know or will search for trusted respectable companies. In Germany and much of the EU, all tuning is stringently regulated, so if the parts are approved, they meet the same standards that the OEM manufacturer has to abide by. Go have a look at a RUF, Singer, Tuthill, 9E, RPM CSR conversion, you may find they know what they are doing and are more than a match for OEM. I'm not suggesting that OEM are not capable just that they are limited. The companies mentioned above remove those limits and produce what OEM should have done in the first place
A four year old 718 hasn’t got much of a warranty worth having anyway. It’s already depreciated by half. If you plan on keeping it for a decade/forever then it’s residual value is of Supreme indifference. If your own it you can do what you like with it including remapping it and it and redecorating it.
The 718 is already something of a weapon compared to earlier incarnations. Boosting it a further ~20% starts to get you into auoercar territory for <£30k soon. That’s never been the case before and I find it interesting.
Unlike something such as a hot Golf which has already been taken by the factory from standard to a high state of tune most of the components in a 718 are already engineered to the same standards as the 911 which is a 180mph car from the start.

Well you feel free, tune your car and play Russian roulette with your money. Just don’t expect Porsche to pick up the bill over any issues!
I have tuned many cars, it's a non issue, most cars have flat spots in them to pass noise and co2 regs, a remaps not always about peak power.my TTRS was flawless at 430BHP for 3 years and what a rocket that was, I also mapped my Exige and my Fiesta ST
The only modern issue with maps is cars are made to a price and BHP level so if you tune too much you might need a better clutch.
I would say a massive % of people owned mapped cars and don't know as too many people map VAG brands and BMW D.
as for porkers, most lower models are detuned so you know you can tune it back to the the top models, it's just a map.
BMW have 316,318,320 it's fake now days they are all the same engine size but with a map !!!
