Are you posting the whole manual? I dont think its a good idea, John D made a note the other day about not posting this kind of stuff...
Is there a copyright notice?
Doesn't really matter.. copyright violations are usually just civil. not criminal... and probably don't apply to sweeden

"So the KLR does not control boost then "
Well, in the stock system it does. The KLR controls the CV-cyling valve which then controlls the wastegate. The KLR sends a duty-cycle signal to the cycling valve (boost-solenoid) that turn on & off like a fuel-injector. This then determins how much pressure gets past the cycling-valve and goes the wastegate. Depending up how much pressure is coming out of the turbo and the particular duty-cycle being sent to the CV, the wastegate will open a little, a lot or not at all to regulate boost. The 3D duty-cycle map that's programmed into the KLR for boost is hard-coded and assumes the stock turbo and wastegate. It doesn't check to see what boost is hit and it doesn't make corrections. In fact, "boost" is not entered anywhere in the KLR's chips, it's only a duty-cycle curve.
As for copyrights, we'd have to check into the treaties and agreements Germany has with the U.S. and Sweden.

The info he is posting is from a book produced by Porsche as an interductory to new model's. They have one for every new version or model that comes out. For example there is one for the Turbo S. That book is for an '86 car. I have a ton of them at the shop. Good info, some of which they did not reproduce anywhere else.....go figure...

Excellent info for an introductory to basic terms and how it all goes together (read: I'm a novice in the Turbo area).
Thanks for posting.

Yes you can, by editing the duty cycle table of RPM vs Throttle posn in the KLR chip, but the results are inconsistant as no two wastegates especially 17-20 year old ones are the same. No one bothers anymore as very good results are obtainable using manual controllers, electronic controllers and standalones like your Link with boost control ability.
