Hi all,
I have been searching through previous articles on EBC installations, however I can not find any that show how to control the boost on primary, transition and secondary turbos.

the articles I found show pipework only attached to the secondary wastegate actuator, thus only secondary boost is controlled by the EBC module? OR the primary and secondary actuators are teed together resulting in transitional spikes...

Do I need to purchase two controllers? one for primary..the other for secondary? OR should I go the mechanical route and put two ceramic ball bleed valves in place of the factory solonoids and adjust them in? (Which would then result in temp changes being ignored (Mechanical bleed doesnt compensate for climatatic influences)

Anyone able to help with EBC's on the S6/7/8? I wish to be able to achive 11/9/11 boost on the current setup, and change it to 20/18/20 in the future with different turbos and manifold (Obviously with lotsa other work)

Any help appreciatted, and I am grateful for all the input so far!

NB: I have an 1998 Australian Series 7 RX7..but the principles all remain constant from what I can see. I am looking at using a Blitz ID3 EBC, but obviously don't wish to purchase anything until I have the installation procedure sorted.

Thanks for that one KAI, I had missed it!

However, it just highlights my assumption that the primary turbo is not being controlled, just the secondary...

as stated below (From robs site)
**********************************************
I have my car setup with the Profec B controlling only the wastegate and you are correct, you only get 10 to 11 lbs. of boost of the first turbo and then a full 14 lbs. or what ever on the second turbo. (but what a kick!)

I talked to Luis at Pettit and he has adjusted his car's pre-control rod to give him 13 lbs. of boost on the first turbo. He enjoys it, because he can hang with those of us that are running 10lbs. on the first turbo, off the
line.

I am going to try and adjust mine this weekend, as I would like a little bit more "kick" in the lower rpm....

I have a question for you though. If you adjust the pre-control arm to give you more first-turbo boost, will the Profec adjust the boost level (via the wastegate) if you have the Profec set to give a lower boost level than is
being produced?

Theoretically it should. My concern is, I like to keep my boost down when it is wet outside (so I don't go sliding through turns when the back end break loose). Plus I like to keep it lower to improve the longevity of my motor
too...

The above sounds like a very poor way to regulate primary turbo boost. is there another way to do this? Should I purchase twin EBC's connecting to different vacuum pipes to adjust the prespool points etc? Sorry for the questions..just somewhat confused.
