Can someone help me use the Knightsport EBS3 boost controller on my FD3S?

Dale Clark had a good wright up on his website, but it is down again, and I can't find any cached pages on Google. I have a copy of the page, but I won't host it without his permission.

Here is something I found somewhere, It may tell you something.
______________
I have two of these things and the manual in jap (also love it!)

The green wire is a doddle, its for the dimmer, you connect it to some other wire that sends the signial to dim it when the headlights come on (say the one to your radio)

As for guidance The device reads boost in KG/CM2 wich is roughly equal to BAR. (so standard your looking around 0.70)

You get a few functions on this device:
Boost Gauge with boost controll ON and OFF (indicated by a square light to the right)
Boost settings (in KG/CM2) will show 0.60 once first turned on.
The third option i dont know sadly! but it goes up in 0.0x incriments.

AS for other functions you can press and hold the top right button to display your maximum boost attained etc.

I asked Knightsports for a translation of the manual for the function and got this: as for installation its a case of plugging the loom connector inbetween your ECU and loom (simple as! no soldering needed)
Quote:
As to the hose connected,
EBS3' s boost control valve,
Top : connect hose to intake manifold or compressor housing(boost)
Side : connect the hose to actuator swing valve
Bottom : free
Also you need to connect the hose(about 4mm dia) to EBS3(silver box).

As to switch on EBS3(silver box)

S-P switch : S:Swing valve
P:Poppet valve
N-W switch : N:Narrow range, the boost is quickly to rise, overshoot will happen.
W: Wide range, the boost is slowly to rise, overshoot will not happen.
First you have to set "W".

Volume dial : set at 12:00
If the boost is not stability, first you need to set the dial 7:00. next gradually turn right the dial.
If the boost is stability on "W" range, you need to also set the boost on "N" range(same way)
Finally "W" or "N", the best condition you use.

As to control pad,

Mode switch push once: boost set mode(you can set the boost using up or down button)
next: off set mode(a little boost set)
next: boost gauge mode

Power switch once : LED lights "-", sports mode.
next : LED doesn't light "-", normal mode.


Finally, you finished to install EBS3 assy, you drive the car to check the normal boost carefully.
(then EBS is power off)
Next you need to set the boost to consultation the above way.

thank you

It is a simple install, I put the brainbox in the center console (behind the ashtray). Hope this helps

If Dale gives the big okie-dokie I can put this one page up on my server for you to view.

Thank you very much Dean. What is the normal boost for the FD and how much boost should I run with the EBS3?

Factory boost is 0.8
What boost level you can run will depend on what mods you have. If everything is stock, I wouldn't go much higher than 0.9, but i'd want a boost gauge for anything over 0.8. (better safe than sorry) (I guess the display would work for a gauge if it's mounted somewhere you can safely watch it)
Factory injectors, fuel pump and maps ect are not going to be enough to keep it from running lean at higher boost levels. there are some good threads about what mods are needed for higher boost without blowing the motor. Is the car stock?

Hi Vega,

It has the KnightSports EBS3 boost controller and a pilot gauge with .05 to 1. Ebs3 reads -4.

I am trying to figure everything out, because the car came to me from Japan. So any advise from you and other members, is great.
