Is there any interset in Electronic Boost controler kits?
As some of you know I've been building a EBC. I did my first test run the past friday and everything went smooth. After testing on my car and a few other turbos which will be complete in a few months, I will be bringing a complete package to the market. I recall someone saying they wanted a DIY kit. I'm just wondering how many people around there are interested in a kit? The current models are 2.5 bar(22psi) and a 5 bar version. It has low boost and high boost settings with a toggle switch. All models will have the ability to hook up to a laptop with a data cable. Which will include software for fine tuning and dataloging the controller.
The kit will be for the base model 2.5 bar / no display. The price for the kit should be 180 or so depending of if you have a boost solenoid already.
Let me know what yall think. Also if there are certain features that you want on a boost controller. Jeff will end up with some kick backs from anyone purchasing from this forum.
Here is a picture of the board ghetto installed for the first run.

Where's the valve?
I had a greddy profec B and it was fun as ----. I really wish it would control boost better (it had like a 1/2-1 psi fluctuation). I think some more pictures and maybe more info on how it exactly works would help get alot of interest.
I always thought that it would be good if the electronics actually read the psi that the motor was getting and adjusted the valve like 500 times a second to give you precise boost control. I don't think that technology is beyond any of the larger companies. Do any of the EBC's on the market do this? The descriptions are only general enough for the average ricer, so I don't know of one that's out there. Sorry for the Q's, I just always wondered about that.

Kyle:
The system contains a pic16f876 microcontroller run a 20mhz CR clock. This system is blazing fast. So might not look like manual switched EBCs. Those should not even considered the same level as mine. Most major manufactures use microcontrollers like greddy,hks, and apex. Some of their base models might not have microcontrollers.
****:
the kit will come with a case, dials,pcb, and everything else needed. This is a similar case to what I am looking at using

The solenoid is under the hood next to the wastegate. The air hose you see is going to the 2.5 bar "map" sensor.
" always thought that it would be good if the electronics actually read the psi that the motor was getting"
I'm not sure what you mean, but my pressure sensor reads the boost at the intake manifold.
" and adjusted the valve like 500 times a second to give you precise boost control. I don't think that technology is beyond any of the larger companies. "
almost all boost solenoids by the brands you know are around 30hz not even close to 500hz. not matter what the company..
I have access to the same resources at pretty much any company. I have the access to all of the EE/CS labs at Louisiana Tech (with permission even). So any tool that I dont own, I have access to.
I will be working on my phd in CAM starting this summer so I will continue to have a very good testing enviroment for awhile. With that I have access to few doctors(of EE/CS/CE) for help designing the board. When you are designing a board for a car the major problem is the spikes/noise/reverse current cause by the car. Other than that there isnt to much that is very difficult.
I will upload some more pictures next sunday.
