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.

wow, that's way more complicated than the one scarecrowX sent me the schematic for.

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.

i hope the $180 version looks better than a chunk of circuit board taped to my dash.

curious to see the final result.

you could prolly get a used profec for that much, maybe a used HKS one too

Will this EBC make my d-series a super cool turbo ninja turtle?

I might be interested with a bit more info. Pics of selenoid and display? Also how boost is adjusted? I'm assuming with laptop.

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.

FooK:

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.

just throw in a diode for that reverse current business, right? I'm working on a bachelors in ee so I'm just getting into this type of ----.

thats a great idea, I was about to get a greddy one, but I think I will save my money to see what you come up with, will you take paypal?

whats the timeline to these being available? I'll guinea pig one.

hmmm... looks interesting. Like the rest, i'd like to see more.

wow 180 bucks? do all the little parts really cost 180 bucks? are you making this as a product to sell, or are you making it for fun and then offereing to sell it? perhaps you could sell it as a kit, you will probly get more buisness that way.

Re:Is there any interset in Electronic Boost controler kits?
 
I'd definetly be interested in it.

I might be interested if it was mappable to throttle and rpm, and with gear inputs. The ability to control 2 solenoids independently would also be nice. Should be super easy to implement. The hardest part of that is getting a stable rpm reading, but that's not even such a big challenge.
However coming up with a good closed loop boost control algorithm that doesn't spike or fluctuate and yet give good response is a bit harder.

The boost is adjusted via a knob. You can adjust the gain and hi/low boost. The basic model will come with the ability to have an external display, but it will not be included. You can fine-tune the boost controller via a datacable.

FooK
The PCB engraver will be here in 3-5 weeks once its here I will do one month more testing. So far the vehicle line up is honda(mine),evo lancer,and a dodge neon. I might be interested in another test vehicle which you will receive a large discount on the product and the option to get you money back if you dont like it. It depends on what turbo you have and what vehicle. I’m looking right now for vehicles that came with a turbo stock.

Spenser
Originally I built it for me, but it seems to have some interest so I'm going to be selling it. Yes the parts are very $$, but some of the cost is going into buying the PCB engraver and drill press. Also check to see how much solenoids and 2.5 bar and 5 bar map sensors cost.

baldur
Right now, I not going to have the rpm input. If I sell a few and there is interest for rpm/gear based boost then I will do it. My main market is for the people who do not want to buy a 400$ boost controller, but want a new, reliable, and very efficient boost controller using the latest technologies and logic theories.
