EBC eliminates boost creep?

[dsm03]

I've searched and have found very few threads on this and I am hoping for this to be a official and last question of this nature.

I used google and came up with a whole bunch of mixed reviews.


Electronic Boost Controllers(EBC)

HKS, Greddy, Apexi

All very similar in comparison, and claim that it will help control boost creep and boost spike, is this true?

I've visited Supra Forums and WRX forums, A lot say it helps and others have said to be thorough and port turbo inlet and of course run external wastegate. Now, porting and running external gates have been proven or at least from what I have gathered from extensive research in our forums.


So, to help resolve this issue for anyone having it and future reference:

Does the EBC help with boost creep?

There are some boost controllers that are poorly designed and can contribute to creep and/or spiking and a properly working solenoid from the EBC could very well fix that. However boost creep is generally a mechanical issue in which the turbine become the least resistant path for exhaust flow bypassing the wastegate. That is only remedied by making the wastegate path less restrictive either by porting or changing the gate location say from the o2 housing to the manifold collector.

Boost spike is a sudden surge that tapers back down to the desired boost level. That would be caused by a poorly designed boost controller, a faulty wastegate, or even a leak in the vacuum line that attached to the wastegate.

Even EBCs have their own quirks, some are better designed than others with having better sensors and solenoids. Depending on your boost goals for the future could also sway you from choosing to go with an EBC as from what I've read anyway, don't do so well around 30psi for accuracy. Not to mention the cost of an EBC compared to an well designed MBC.

Take the Hallman Evolution Pro MBC. While known to be a high end brand with a price tag, it's still under 2/3 the amount of the cost of a EBC that is decent for design and not to mention, it has in-cabin adjust ability.

The Reason why I would want to switch to a EBC from a manual is for some of the said reason(s) accurate boost settings low and high boost level settings, and maintaining constant pressure and keep the car from spiking. I would however recommend to anyone to go external wastegate and if not port the crap out of that turbo.
