I built one myself too, but with a map sensor for PID control and a serial port for datalogging / configuration! Also, using a microcontroller directly to make it even more dirt cheap.
i asked him to build exactly this, he wanted to do all sorts of crazy things, issue with building a closed loop system is now you need a customizable PID loop to control that also, and a map sensor, etc etc
Yeah, I would want to set a boost target, I think there is an old Volvo boost controller that could do that and it was pretty easy to find in junkyards years ago. The only issue it had was that the target range was limited, probably by the pressure sensor more than anything.
PID is very easy to do. Although it is probably easier to just add a 3D map, depending on which inputs you get from the ECU. With CAN rpm and load should be easy to do.
Looks like the ticket Matt! I don't know if you seen my comment a week ago, but I'd love to see you piece together a diy meth kit on a budget. One with a descent pump, and proper hardware. More than just a washer bottle. Maybe someday in your busy schedule, I know you have big plans as of now. Thanks for sharing!
simplest way for that to operate would be one of those pressure switches. ordinary oil pressure switch will work as pressure swith to ground an relay for that box.
yeah there are alot of options he wants to build in like some sort of boost amount display and possibly a cut safety and multiple boost settings accompanied with not activating the solenoid till 90+kpa also, i just wanted to see a super simple proof of concept
If you go to turbos garage they have the ratchet shift trans with boost settings on a tahoe. Pretty cool. All this electronic stuff is way over my head.
@Sloppy Mechanics I don't know if you ever watch Mighty car Mods, but a while back they had some electronic wiz kid who had put the electronic boost controller in hidden menus on a factory radio!
With the capabilities of an Arduino, a boost referenced boost controller would be more ideal. Instead of setting a duty cycle, set a target pressure (PSI, BAR, KPa) and the Arduino does the rest. No ramp rates.
yes everyone must have missed the part where i said, this is a proof of concept and many advanced features are already working on dales test rig, i just wanted it to do only this and test its functionality, before we add 50 features that all fight each other and get frustrated coding and give up.
you can buy an electronic boost controller incluiding solenoid valve for 130 bucks on aliexpress. which i think is expensive for chinese dirt, and not much to it... either way it'll probably work with no issues.
Read man! It's a complete controller, as i said. with a solenoid. (a "programmable" closed loop controller) www.aliexpress.com/wholesale?catId=0&initiative_id=SB_20180222162326&SearchText=auto+electronic+turbo+Boost+Level+Controller+Bcu
this only makes sense if it's dirt cheap when bought or as a do it yourself project. it wont be cheap with an oled display a genuine arduino as a base, then you need voltage regulators and a power-fet, a case etc. if you add a PID function you'll need a pressure sensor it goes on and on. the controller now is doing hardly anything at all. it only scales the analog in(the pot) to a pwm output and shows the dutycycle on a screen.
yeah, i am a bit confused by this things lack of functionality too. I think definitely the biggest issue for a fully functional item is definitely the code. You can buy a Nano, pressure sensor, solenoid and voltage regulator (i dont use the big units on ali express.. better to buy one of the tiny mosfet looking ones for a few bucks from radio shack ) but without decent code it wont be worth shit. You need to be able to give a target boost setting and then also be able to adjust the gain/responsiveness (from my experience the gain control is VITAL as no setup is the same with longer/shorter hoses to the pressure sensor and wastegate/solenoid) I loooove the idea however!!!!!!
The problem with using the Atmel 328 chip for an automotive application is their temp rating is way too low, put this concept on a Microchip PIC controller. PCB's are cheap (ie low $$$) and it's a simple concept so why not prototype some ?
Man i got to start messing with Arduinos. The ease of turning it up and down is awesome, it would be nice if there was an overboost protect. But as stated that adds more BS.
I love the sentiment but there is much more to an EBC than just pulsing a solenoid. :-( (sad face because i want to say something positive) It needs a pressure sensor, adjustable gain control and (others will know much more than me, i dont quite remember) but do you not also need a bleed between solenoid and wastegate? (otherwise the pressure at actuator will only increase with each pulse, not decrease)

They are like anything else, can get good expensive ones or cheap eBay ones. Most of them are 110 in and 12v out, but I know I have saw them in 12v in somewhere... for the guys who like to tattoo out of a van or whatnot..... lol
blindabinda123 - people did that back in the day, but it has distribution issues and needs to run rich enough for the lean cylinders to not have issues
It would be okay for a relatively low boost setup, but the distribution issues would be a limiting factor for sure. Definitely better off with larger injectors
I watched two minutes of a TJ Hunt video, got cancer, came here, and now the cancers gone.
Same here Shanely. I said to myself "What the fuck am i watching?"
Shanely Shane it’d be almost halfway okay if he even videoed what he did with trucks and such
I built one myself too, but with a map sensor for PID control and a serial port for datalogging / configuration! Also, using a microcontroller directly to make it even more dirt cheap.
Any info on how to do this? I'm really interested in trying this out
It lacks a feedback loop.
It would be much more useful with a MAP sensor input and selectable desired boost pressure.

Can't you read off the stock map?

This looks like what I need to run my injectors on the bench cleaning system that I’m building for junk yard injectors.
I’ll have to snag one. Thanks!
AGearHead4Life we need more third gen and vandal and everything. I would even enjoy some squarehead lovin

yeah maybe one day we can visit the pump meth after we lean on it with ethanol for now
I was just researching Arduino boost gauges and stuff today... this is seriously ideal.
simplest way for that to operate would be one of those pressure switches.
ordinary oil pressure switch will work as pressure swith to ground an relay for that box.

You have an amazing wife.. my garage time dropped 95% after our kids were born. Lol
tj86xj, You get 5% more garage time than some fathers I know. 😒
SenselessTuning - I wish! Haha
the only garage time i was allowed after kids was to fix HER car
You are lucky to get that much.
Yes!!! Been waiting on when you where going to get it!!!
The best idea would be to have a map sensor to trigger the solenoid after a set pressure is achieved.
If you go to turbos garage they have the ratchet shift trans with boost settings on a tahoe. Pretty cool. All this electronic stuff is way over my head.
Cool stuff Matt!
I was going to build a closed loop, set the PSI and it makes it happen, but i don't have a turbo car.
Learned a lot watching your videos. Keep it up!! 🖒
@Sloppy Mechanics I don't know if you ever watch Mighty car Mods, but a while back they had some electronic wiz kid who had put the electronic boost controller in hidden menus on a factory radio!
i did see that, really awesome all the features he packed into the stock dash interface
This is an overly complicated bleed valve right now

Ive been dreaming of teaching myself andrino. Ive bult many PCs but kinda slacked off last 6 years= wayyy outta date. I totally need 2 do this
you wont regret it! only a few bucks off aliexpress and once you have the capability you'll realise there many relevant projects on ya vehicle

ldperformance.co.uk/product/electronic-boost-controller/ this is cheapest i know and it works good.
Need a Hobbs switch to activate only in boost otherwise the mac valve will wear out fast I'd imagine. Good stuff though!

wouldn't really, you could have the coil grounds going through a solid state relay that's controlled by the arduino
you probably wouldn't want to cut the ignition!!
Cut the 12V to injectors rather.
Pretty cool
is there a way to wire a map sensor input so the arduino can regulate to keep boost level stable vs useing a static knob
Fuck. Yes.
Fuckin cool.

if you are using a 3-Port as it is ment to be then no.
Why not hook up a map sensor and have it set the boost level?

Could you not do this with a tattoo gun controller? i think you can get them12v also?
i guess this is a great suggestion, are they 12v dc output?
I am not 100% sure, I believe you can get them 12v input and I wouldn't be surprised if you can get 12v out.
I see that they are 12v output.
well this is quite the discovery, how much are they, lol
They are like anything else, can get good expensive ones or cheap eBay ones. Most of them are 110 in and 12v out, but I know I have saw them in 12v in somewhere... for the guys who like to tattoo out of a van or whatnot..... lol
Sounds like your boost control needs a boost at 60% and above
void setup() {
pinMode(bec, OUTPUT);
//bec is boost electronic controller output to attach a PWM Transistor or Mosfet
Serial.begin(9600);
}
void loop() {
int sensorValue = analogRead(A0);// sensor is pressure transducer 0/5v ebay
float voltage = sensorValue * (5.0 / 1023.0);
float pressure_pascal = (3.0*((float)voltage-0.47))*1000000.0;
float pressure_bar = pressure_pascal/10e5-1;
Serial.println(pressure_bar);
if (pressure_bar>0.5){
analogWrite (bec,50);
}
}
// ETC ETC
eh h I still prefer they old vacuum ts in wastegate line
Hey will that work on a megasquirt that’s plug an play on a ford
This would work on a carb'd engine, or anything that has a mac air valve controlling the wastegate(s) so I'd say yes.
What's up buddy
Could you install a fuel injector or two into the intake somewhere on a aftermarket turbo vehicle and use that to control afr's somehow??
blindabinda123 - people did that back in the day, but it has distribution issues and needs to run rich enough for the lean cylinders to not have issues
tj86xj even if the injectors where installed say before the turbo or before the throttle body. I'm just curious. Nothing ill prob ever try. Lol
Actually, Matt did this recently on his friends newer V6 Silverado turbo setup
tj86xj really. I'll have to find it
It would be okay for a relatively low boost setup, but the distribution issues would be a limiting factor for sure. Definitely better off with larger injectors
Looks like a power supply 2 a tattoo gun
