First here is a link to the product.

I ordered the product almost 3 weeks ago, received it today finally after it sitting in NY for 5 days doing nothing!

The product is supplied with a solenoid that is adjusted by a turn dial switch. Everything is plug and play, its powered by the cigarette power(whatever you'd like to call it)

First things first, I have a R85 with a external wastegate. I was attempting to control boost with a manual boost controller. It just would work reliably I would try and set it to 12psi and in higher gears it would try and creep. There was nothing I could do to get around this, so I decided to start shopping for a EBC. The market prices for EBC's seemed to sky rocket, brand new profec's now sell for 400$ when I could find them NIB for 250$. I decided to search to see if I could find anything priced lower that will work just as well. So I came across this D2Power EBC.

Installation was very simple and easy took about 4min just to have it ready to test it out. I warmed up the car drove around for a little bit so temps will get to normal operating temp. I adjust it a little at a time, boost raises everytime I adjust it. I only had to turn the **** almost to get the goal of 15psi. It now holds 15psi reliably no creep or spike and it hits boost much much faster then any of my manual boost controllers did! For 80$ shipped I think I got a great deal, I can adjust boost just in a turn of a dial. Boost builds extremely fast, even with it set on low the car defiantly feels much faster and harder hitting.

I already have a boost gauge so there is no need for a fancy display HUD, it's very basic and it does a great job at controlling boost. I am very satisfied with the product. Tomorrow I am going to hard wire it so I can plug my radar detector back in and get rid of the silly missile launcher switch. I highly recommend this product to anyone. It does what it's suppose to, I have gained boost response and power. I get absolutely no creep and it holds boost steady right to redline.

 

Thanks, I now know what I'll be using.

 

Don't you have a haltech?

 

can you not use the arming switch? it seems according to the site, the switch is to turn it on, i rather have it on all the time.

 

Yea if you hard wire it you can bypass the missile switch. The switch is used to turn it on. If hardwired then it will always be on.

 

Yes, a E6K. Why?

 

you said the boost comes on faster, does this mean the solenoid has a port that goes to the top of an external wastgate that keeps the gate closed longer by putting positive pressure on the top of the diaphram? How many ports does the dolenoid have? Are they labeled the same as other EBC's like NO, NC, and COM? Thanks

 

This isn't a full electronic boost controller. It WON’T make your car spool up faster, but rather stay the same or slow spool up. Leaving it "hardwired" defeats the purpose of this devise and it will essentially ALWAYS BE CYCLING and although I don't know what solenoid it is, I doubt its meant to be run for extended period of times. The entire purpose of this "controller" is so you have normal boost (waste gate spring) then you can run a higher boost setting when you flip the switch. This thing has no logic, no feedback loop, no way to monitor manifold pressure. It’s just a solenoid that bleeds off pressure via cycling. The rate of cycling is set via POT or potentiometer. Don't get this confused with a real EBC. Not knocking the product, I'm sure it works great for its intended use (cool button that adds boost or {scramble boost} type of thing). It bleeding off pressure the way it does will NOT make your turbo spool up faster. It will spool basically the same or slower than the standard WG spring. It does not keep your wastegate from seeing boost till target boost is reached (only found on real EBC's and some MBC's). It only hooks up to one port and continully cycles when its on.

Think about how this really works before someone sticks their foot in their mouth (again maybe) or claims things that defy physics. Or perhaps theres a full logic to it and I missed the MAP sensor and programing??

Your answer (from reading the auction add) is NO and NO.

Its like putting a hole in the line that goes from your manifold pressure to your wastegate. Except this hole you can control how big it is and turn it on and off.

So the OP had a "placebo effect"? Interesting.

 

Maybe his *** dyno needs calibrating ?

 

Because your K has a boost control feature. Just need to get the solenoid - which can be had cheaper then what Haltech sells theirs for (13b RX3 has some posts about it)

You can map the duty cycle by RPM all the way to redline. This aids in taking some of the "up n down" control of the small port valves like used in the Haltech solenoid. Its also good for a car thats bleeding boost/boost creeping a bit (PRESUMING THERE"S NO HARDWARE/BUILD ISSUE) because the duty cycle can be raised or lowered at X rpm to compensate.

You can also have two wastegate maps for seperate boost levels.

 

Yes it's also hooked up to the top of the wastegate... solenoid has 3 ports

 

I get what your talking about and also thought of this as well when I was hooking it up. It is not a real ebc, you cannot adjust then gain. it's just a basic solenoid thats set by the POT. It is hooked up to both ports on the wastegate. I was just writing my thoughts on the product, but guess do to it being set for a higher amount of boost, it will reach 10psi faster then before due to the cut off not being till 15psi.

 

I am happy with the product though, it does what I wanted it to do and thats hold 15psi without creeping. My mbc could not do that.

 

As long as it does what you want it to, then Kudos!!

I still wouldn't recommend wirering it on all the time though. Imagine what would happen if if that solenoid wasent designed for continuous operation and it stuck shut :O D'oh!! If you like to way it works, perhaps install a pressure activated switch so it only comes on at a set boost level (like 8 psi)?

BTW, keep an eye on your boost pressures with different temperature changes. It WILL vary your boos pressures with temperature. Weather or not its tolerable or even apparent will be the question, so just keep an eye out for it (MBC have the same problem)

I built something sorta of simular to this years ago. Basically a dual boost controler. I had WG setting or I could install MBC, then I had a continuous duty solenoid plumed so it would activate another MBC. Basicaly so i had two boost settings and could raise it with a flip of a switch. Had to go under the hood to adjust it though.

Yea that is something I am interested in, to see if boost changes when the weather changes. I really don't want to screw with it just yet since it works so I rather just leave it alone.

 

i just ordered one, ill let you know how mine works on the GT42 w/ PFC

 

btw can you pos pic of your install

 

Yea sure i'll post pics tomorrow for you, email them and tell them you have a external wastegate so they can send you the diagram for it. Please reply to this post when you receive it and test it out. I would like to see what you think about it as well. I turned it less then a qtr of a turn to hit 15psi.

 

pics?

 

I am trying to find my digi so I can take pics, what do you exactly want me to take pics of? I have a vacuum port coming off my turbo elbow and run that line to a T I then run the oppisite side of the T to the top of the wastegate and the lower to the front of the solenoid. Then from the opposite side of the solenoid to the side port on the wastegate. I then ran the wires where the engine harness is inside the car under my center console. I cut a hole in the middle button and put the POT adjuster there and plugged it into the power.

 

What's the lowest boost you can get? And how strong is your WG spring?

 

the lowest boost any turbo system can hit is whatever the wastegate spring is. So if it's an 8 lb spring then 8 psi is the lowest boost.

If i remember correctly a boost controller can reliably control boost up to double the spring rate. so an 8 lb spring is good for 16 psi. Though im sure there is a certain amount of flexibility up and down on this little rule.

 

Yes, but I'd like to know skir's specific results while we're discussing the operation of his boost controller.
