It may be a dumb question but ... why? You could just read ECU from Cayenne and flash it into the other unit and save messing with electronics altogether.

 

Im learning this stuff as i go im no expert.
Hence the " easy" power upgrade.
Just an idea that popped into my head since bothe are basically the same car . Have something patience for a rooky

 

If you were tuning a 3.0 Tdi you'd easily get another 40 bhp which you would really notice.

Tuning the 3.2 gasser to get another 16 bhp - if you are lucky - is such a small increase you wouldn't notice it.

 

I got 18hp more tuning my NA 3.6L B6 passat with the Unitronic tune and although it was $500 for 18 hp it was well worth it.

Now the 90hp for $500 on the wife's Tiguan was a bargain!

Patience is abound, it just makes it a more complex process, since you will need to recode all gear to see the new ECU correctly. It is not a trivial process. Flashing the maps is much easier.

Have you looked into HPTuners? You may be able to pull engine and transmission maps and do 1:1 change without touching hardware at all

Now you have put a smile on my face and gave me some study material.
Thank you for the info. Will post updates if i go through with this or any other method

 

I dont have the gear nore the softwate to flash the ecus so.... Again the swaping idea

 

as far as I can read, HPTuner should be able to read and flash both systems. You can confirm with their support. In that case, you will not only be able to map from one car to another, but also tweak settings as needed, to your heart content. I am in the process of doing something similar, taking maps from Cayenne and looking into doing some tweaking on my Q5. There is a learning curve, for sure, but it is cheaper, and you can always go back to stock if you mess up.

 

Ain’t no thing as just straight swapping. You’ll have to remove or recode the immobilizer, record your current ECU coding, hope the Porsche ecu will accept your old coding, etc.

 

And you still won't notice the difference in the small.power increase!

 

I’d attack the things you will notice a “bump” from first. Lighter wheel/tire combo is always an easy one.

 

Lmao... Yeah, let's shave some tenths off our time attack laps with a Touareg. You guys kill me.

 

Glad we can provide entertainment for your miserable existence...

 

Sweet, one more fan

 

For more entertainment. 😉

 

Eh, it’s all good as we all know you know your $*#t, you just don’t seem to know it stinks.

Now please offer the OP more than commentary to prove me wrong, lol. At least tell him he needs to buy a Cayenne ECU along with the Cayenne it belongs in to really get the desired HP bump. 😄
