Here is a picture of my current project. Its a 2.5 bar electronic boost controller. It looks pretty odd here because its still in the testing and the boards are hand made. When its finished it will be cased and and made with a real pcb. I might put a LED display to display the current amount of boost.

My first impression of it running is that I started building boost around 2k and with my mbc I started around 3.5k.

Here is a pic I took tonight.

looks good, any idea when it'll be done? price?

LOL is that stereo wire?

Looks like a cool project. Hope it works out.

Sinner

yup, those are stereo wires. I just wanted to get the controller going. This project has been in the works for around 6 months.

Currently, I'm prefecting the algorithm on the controller the hardware is basically complete.

I hope to have the basic model less than at or less 200 dollars. It depend how much of a discount I can get when buying the parts in large quantities.

The features will be the high boost/low boost via a toggle switch and a boost display in psi on the some models.

This model will limit out around 22psi which can handle most honda turbos, but after this first batch I will be using a 5 bar map for the cars that need more than 22psi.

Since it has an integrated 2.5bar map it will swap out to any turbo car out there with internal and external wastegates.

If you have any ideas/ request let me know and I will consider them. I be hitting the market in about 1.5 months. Alot depends on the PCB machine I have on order.

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? o and does it come with the speaker wire?lol

What kind of features will you add to this thing?

racinskittle

are you using the Motorola chip for this? Just curious. If you are...Im trying to figure out what kind of tolerences those chips have. I was gonna use it in my electric boost gauge.

that's gonna be hot when youre done

Features:

1. Hi Boost / Low boost via a switch
2. boost gain adjustment
3. lock switch
4. laptop tuning via a datacable
5. upgradable with External display that will display boost.
6. Possibly a turbo timer.

I ordered my PCB engraver to make the boards last week. It will take about 3-5 weeks before I get it since its custom. I'm using a PIC microcontroller with a 20 mhz cr clock which runs about 5 mips. I like speed ;-)

Yikes. For $120, everyone here can buy the MegaSquirt and only use its boost controller function.

(Civic_Duty)

megasquirt doesnt have techincal support and it comes in a kit which has to be built and is easy to screw up... bad idea. I'm sticking to what works

beepy

LOL. Oh to be the uninformed.

Tell me, would you rather have something built in your basement, or something built in someone else's basement? A monkey can solder.

Sinner

I will have kits but those probably will not come a warranty. They will be priced similar; depending on what is all is included.

I have looked the the boost controller algorithm from megasquirt and talked with jeorge(forgien) a designers for genboard. The boost control algorithm is weak, but the electronic designers are pretty sharp. Atleast the ones I talked to.

So are they a real competition no, but given a few years maybe... I like competition. I will be starting my PhD this summer in CAM and Im finishing my masters in CS with a perfect 4.0 gpa so I have very strong background. But you say this was made in there basement? I’ve built/tested/tuned in a EE/CS labs at Louisiana Tech University (with permission even). So its not a really good comparison. Then again you probably dont have megasquirt running or you never actually looked into the boost control of megasquirt.

I dont want to argue, this is just a affordable boost controller for those who want a new, reliable, and very efficient boost controller using the latest technologies and logic theories..

If you don't want to argue than don't make personal attacks. Yes, I have had running MS's before, and building a new experimental one for my car, using the "weak" boost control algorithms and DIS support.

I don't know what algorithm you were looking at, but IMO it is quite robust. I can set target boost on a 8x8 table (RPM and TPS), and I can set it to cut boost any amount when knock events are sensed by the MS. B&G, and countless other persons much more educated than myself have spent years getting the MS to what it is today. (I am a lowly Mechanical Engineering student)

sinner, check your pm's

Sinner

I'm curious, I've read their algorithm, but I never looked at their parts list. Which solenoid are they using?
