Anyone planning to buy an EBC?

I was thinking about starting to pick up my parts for my new Stage 2 kit. Anyone running a Profec B Spec II?

Thanks,

Heya Mike,

Since I have spent quite a lot of time working with MBC's, I definitely think I have a handle on their limitations. The conclusion I came to is that I probably would have been better off investing in an EBC from the start.

I went to CMS on the weekend sale and got some prices from them, but they weren't very reasonable.

I have done some research on the products. The three MBC's I have been tossing around are the Profec B Spec II, the Apex'i AVC-R and also the new Profec S.

The AVC-R is the most advanced in my opinion but also the most expensive. I think the Profec B II has a very solid reputation as a good product, and it is also less expensive. The new Type S uses the same solenoid as the B, and has basically the same features including adjustable onset and boost level - and is easier to set. It does not have some of the fuzzy logic and scramble type settings that the Profec B has, however such features would be of little to no use on a 1.8T from what I can surmise. Definitely consider the Profec Type S if you are thinking about the Profec B.

Anyhow, good luck choosing one. I think you will find that the best prices are for used units, or new ones on eBay or through buys/retailers on forums such as the Vortex (or if you are industrious, scan some of the Honda/Import forums).

One thing to remember is that just like MBC's, EBC's are not throttle-sensitive. Therefore they will deliver boost based on when the turbo can deliver it (a factor of engine load and RPMs). However, the VW ECU and the maps it uses, even those maps made by chiptuners, do change boost based on throttle position. Therefore there will always be a fundamental conflict between the requested and actual boost levels at part throttle. This conflict cannot be resolved through MAP clamping or other trickery I have yet seen. I also have not heard of any chiptuner who has changed this property - as far as I know it is something they "work around" since it is a fundamental part of how the bosch ecu manages the turbo.

Hey Kor,

I thought the gain % level will set the boost to come on and off differently so the throttle is much easier to use and limp mode during PT is sometimes avoided?

$550 at Speedtech i believe for the Spec 2 and Type S

Yeah 'sometimes', gain is just gain.
