So it has been done.

COBB Tuning - Accessport for Porsche 718 Cayman / Boxster

The Accessport V3 is the world's best selling, most flexible, and easiest to use ECU upgrade solution for your Porsche. Unlock power hidden within the vehicle by replacing conservative factory settings with more aggressive calibrations.

For you that have some knowledge how accessport works, is it only a way to create different tunes?
Is there a possibility to have Normal mode stock and sport/sport+ tuned?

I just might jump on this

It let’s you ‘flash’ different Maps (only From Cobb) to your ECU, and remove them when you want to go back to stock. The modes selection is not there with the COBB maps (for now)
The GTS ECU still needs to be unlocked by COBB so no OBD flash available at the moment

Cobb also has tune thru the port without ecu needs to come out as of today
Hence the question to cobb users
I also have asked them if it is for 718 all over the world

Porsche 991.2 and 718 Accessport Improvements

In an effort to continue offering the best tuning solution for the 991.2 Porsche 911 and 718 Boxster/Cayman we are constantly looking to improve our solution. Improvements come in many forms, from simple firmware udpates to add features, updated map files to provide more consistent or smoother...

This is a piece of information I have never read in any of the threads before! Thank you CupraLeon!

Does this hold true for the APR tune (i.e. that once you load up the APR tune there is only one mode)?.

 

[johan]

According to cobb download page

Stage 0

• Stock calibration. Factory map that the car was delivered from Porsche with. Does not uninstall Accessport.

I guess that means Porsche still can detect the tune if that is anyones concern

Thx, it didn't mention sending in ecu for the 718 on their site so I tought their site was up to date, my bad

At the moment APR is the only one offering different mappings for the selector, and also the inverted function of the start stop.

just to be clear EVERY tune is visible for Porsche not always for the dealer (in case of powerbox like the one from DTE systems when removed)

In that regard APR is a really choice, i wonder how long it will take for them o cover more revisions.

@johan,

I would check with different COBB pro tuners about the mode selection interacting with the tune.

I deal with a well known Porsche racing shop in the USA, and they told me that I could have Normal mode stock and sport/sport+ tuned using COBB.

They even told me that they could use COBB to add a Sport+ mode to my non-sport chrono 718.

I haven't done the tune yet, so I can't confirm this is 100% true. However, I would advise you to check with multiple COBB pro tuners because someone might be able to accommodate your request.

 

[CupraLeon]

Also waiting on more info, especially for the gasoline particulate filter mine has. It seems the best tune around to me, the research they do and testing is far above most tuners and also the knowledge they have of the ecu so they can implement the use of the selector and other original functions says alot.
take a look at the extra sensors they use when testing:

 

[Viffermike]

Wait -- are we sure that the 718 flat-4s use the Bosch MG1 ECU module? As I understand it, it started being used by Porsche in 2018 on a couple of SUV engines shared with Audi and on the 4.0T in the 992.2, and it first appeared on Mercedes diesels (the MD1 variant) and Audi B9 engines in early 2017. No mention I can find anywhere says it's been retrofitted onto 718s (and in the middle of its life cycle) ... ?

I realize that I may have incomplete info ... but it took APR more than two years to crack the MG1 in the S4.

 

[CupraLeon]

Mike, my bad should have pointed out that it was on another engine, it was ment as an example of how they place the extra sensors. The 718 2.5 use a Continental SDI 21 ECU for the 2.0 I did not do any research and therfore haven't got a clue what ecu it has.

Probably the same Continental ECU ... for now. Porsche is reportedly moving everything over to Bosch over the next few years -- a byproduct of VW AG consolidation. That said ... I would not be surprised in the least if the new NA flat-6s in the GT4/Spyder have the MG1 installed.

Some years ago we had this about COBB and the mode select switch:

COBB Accessport Info released for 718 series

The first thing I mentioned was the difference in dynos and environment. That should make no difference in this conversation since I’m using the numbers published by these two very reputable tuners/companies. Numbers which just happen to be very close to each other. I have no reason to believe...

According to Cobb so will the OBD/accessport tune work on any 718.
So there must be a difference between the different OBD tunes out there.
APR change things Cobb does not, i wonder why.

We might start a new thread solely for OBD tunes?

OBD tune means the tuner has found/or sourced 'a(software) key' to get into the ecu.
The other way is to open the ecu and
1)write a new eprom chip and change it with the original (mainly older cars)
2) make a connection with the right pins(BDM port) on the motherboard to get to the eprom holding the data and read it/write it this way
some video's in German that show the 'non OBD' method:

Why APR has those extra functions: APR has the ability to alter the code structure of the ECU through code levels changes, and are able to add features to the ECU.


To be clear I'm not payed by APR or a fanboy

Yep thats like basic hacking and that is why i am suprised.
If it is that you can break the code and be able to change what ever you want why not do as APR?
If the software is protected in layers you have to break them all to be able to change things like different driving modes etc etc

I am just curious

The COBB AccessPort no longer requires the ECU to be sent in. As of last week "front door" flashing is supported.

The AccessPort allows you to download standard "stage" maps and flash them to your car. You can also work with COBB Pro-Tuners, like us, to custom tune your car to further optimize power. We can also develop maps for non-standard hardware configurations that aren't supported by stage maps. We have an AWD dyno we use for developing maps on. This helps us build our base map library that we use for e-tuning cars all over the world.

Is there a tune that replicates Sports Chrono mode, with rev matching?
