Electronic boost controller for turbos
What is the benefit of electronic boost controller over the mechanical springs. Is the ebc beneficial to someone running 9-10 lbs of boost? How does the controller regulate boost, . via an electric actuator? If one purchases an ebc , does everything needed to put it into action come with it, or do you have to buy other parts to make it function? I am switching from a centrifical system to the APS twin turbo system and would like to know if I would benefit from the electronic controllers.

Unless you have a custom tune for each boost level that you can download into the ecm - I have this for my tt. I use a hand held hypertech controller to program my entire ecm with the optimal fueling and ignition timing for whichever boost level I choose to run.
Hope that helps - IMO, if you run a boost controller, you had better be able to go to the higher boost level on pump gas otherwise it is pointless, and you're just sacrificing your low boost power all the time!

The ebc is for a second boost level in excess of your mechanical spring boost level. Using an ebc is a compromise in most applications. You can't have perfect fueling and ignition timing for both boost levels. As you turn up the boost, you need to retard the timing, so you set the timing to be safe for the higher boost level, and you have to accept that timing for the lower boost level too, which means you get less than optimal conditions for both boost levels, and less than the most power at each.

With an EBC you can get more torque than you would on just wastegate springs for a single boost pressure. So don't just think about an EBC solely as a device for multiple boost pressures.
Also, some of the nicer EBCs can let you control boost ramp rate. So if you find that you have too much torque and want a little more horsepower, you could setup the EBC to allow that.

Thanks for all the info given in this thread. To reform my question , will the ebc perform better than the springs based on one set boost tuned for. Can I increase the spool up time or decrease the spool up time in the rpm range with ebc? Is the ebc more accurate and dependable for a set boost?

Turbosmart E-Boost2, all that needs to be said. Blitz SBC-ID1/2 are easy to use as well. AEM has the New Tru Boost Controler, havent messed w/that yet but it looks good. We use the Eboost most of the time.

correct...SD tune reads the map sensor and then looks up predermined value. ill post a screen shot when i get home.
so w/SD a EBC is a nice fit, just turn it up on the fly

You won't change spool-up time, but you may change the way you feel the boost (hence my comment about torque). Think about what is mechanically happening with wastegate springs: as boost increases, more pressure is put against the spring. Let's say your car is setup to run 10psi on wastegate springs. The wastegates have probably already started opening around 5-6psi, and they open more and more with every pound of boost, which means that before you even hit your boost target you are already bleeding exhaust energy (making it harder to hit your boost target!).
If you had an EBC sitting in front of the spring, the EBC is seeing the boost before the spring, and depending on how it's setup, might wait until 8-9psi before allowing enough pressure to hit the springs. You might get the exact same 10psi of boost, but you weren't bleeding boost as early to get there, and so you might make a bit more torque.

Eh, I don't have much experience with EBCs vs. springs, but here's my take...

you are referring to "gain"

I have the Tru boost controller on my z06 and it is awesome! You Can adjust the boost from the gauge.
