General Discussion / Re: Android App Issue: "LBB Version Unknown"
« Last post by crodgers on March 17, 2019, 03:57:28 PM »
Wow thanks for the quick reply! Yes I did restart the app by restarting the tablet.

One other difference that might be worth mentioning is that the "LBBdev" device was not listed in the firmware update device menu. In your instructional screenshots, you had LBB and LBBdev showing up in the menu. Not sure if that matters.

I borrowed the older samsung tablet from a friend, I embarrassingly do not own any android devices. I might see if I can quick ask a friend this evening to download the app on their phone so that I can try it out on a newer version of android OS.

I'm digging the Arduino IDE though, pretty fun to tinker with, and I bet its a blast once you're proficient with the programming language and it's applications.

I'll circle back this evening if I get a chance to try out a newer OS.

UPDATE: I tried the app out on a friends phone with latest version of Android. Still received the same message unfortunately.

Thanks

Have you reset the app ?

I can try some downgrade options and see if I can replicate at home. Won't be home for 9 hours though.

General Discussion / Android App Issue: "LBB Version Unknown"
« Last post by crodgers on March 17, 2019, 02:30:47 PM »
Has anybody encountered this issue:
"LBB version: Unknown
Minimum LBB Code version is v.3.0.0
LBB update is mandatory."

I'm about 3 hrs into troubleshooting this, but am a complete arduino noob. I've attempted updating the firmware with the v3.0.0 hex common code, the upload succeeded but is still not recognized by the app after the lbb resets. After some reading and trial and error I was able to get the IDI to compile the .ino sketches in the hopes I could update the firmware via usb. Everything upuloaded ok. But I'm still getting the same error in the app. I'm using a tablet running Android 7.1.1 if that means anything.

Any help is appreciated! Trying to get access to the tuning menu to calibrate the turbo and adjust the curves.

Thanks

Curves don't come out of thin air, it's trial and error. That's the whole point of making variables tunable.

I would suggest you look the wiki over quite extensively. There's a whole section for the tuning application for android > android_app [Lil' Blackbox]

If you want to get into the actual coding on the device, there's a section with some good info to get your feet wet > common_code_v2 [Lil' Blackbox]
You'll need to download the common code, the arduino ide, and the libraries associated with the sketches. Import them into the IDE, and start poking around to get the jyst of how the code flows.

There are a lot of tunable variables just within the setup section, that you can adjust to drastically alter how the controller works. I've written a lot of custom code for my personal controller. It integrates the 5v square wave from the crank signal to count engine rpm. From that I'm using a basic 2d map of engine rpm to vane position until turbo rpms exceed 105,000 then it falls into the top end control section. I might go 3d mapping with engine rpm / turbo rpm = position, however throttle response is pretty good and it would seem a bit over the top to do that.

Comment:

The thing about controlling two turbos is the entire logic will have to change, and to do that effectively you're going to have to know or learn some C programming skills..

Thanks for the feedback. Is their someone here could pay to look the new code? Do I simply need ask for a controller with curves for the 3.2 and get studying on C+?

I found on my truck the HE351, despite being a nominal 25cm housing at wide open, the choke point is too small a turbine in it with too many blades.. If you went with a 64mm 10 blade I think that would be a happy medium, I have the 67mm 10 blade and that's a bit big honestly (on a 5.9L at about 500 hp)... When I had the 60mm setup I was wide open at about 2400 RPM.. On a smaller engine I think it might work well though as it is.

Question:
How are you going to physically redirect exhaust flow from the primary to the secondary ? Wastegate ?

Answer:
Going to allow exhaust flow from the primary outlet into the secondary inlet....

Comment:
IMHO I think twin is the best application for these VGTs. Single controller, simpler piping. Combined airflow.

Response:

Not challenging that, but I already have the two units mentioned (lets see if we can knock our heads together to make it work)......  I remain open to changing the setup, but i would like to try it before to throwing my hands up. 

I would prefer my next major spend be the controller, if it fails i could reprogram the LBB to work with the single 351ve, unit I can and move on with a new turbo/setup..

v1.0 - v1.1 / Re: My life, My coding

I have 7x010s in right now, but Mr Farrell did his magic to my 215 pump. I have 3 notches at the AFC area for the fuel plate. 500/400/300ccs maybe even lower I can't find the paperwork.

I've tried all sorts of settings and my ass dyno says that blasting black is marginally if at all faster than where I have the fuel plate now. I know that the coal absolutely killed my mid range. Right now my truck is up on top of the turbo by 1700rpm and slipping my ceramic clutch in 3rd. Clutch is supposed to be good for 550/1000 /shrug. That's with a 3.55 rear w/ LSD. 265/75/16s

I want to go smaller sticks and open up the pump, maybe it'll get some more timing or something.. or just overall be better. I'm definitely over having SACs that's for sure. The haze bothers me so much.

Sorry but you really haven't answered my first question. How are you going to physically redirect exhaust flow from the primary to the secondary ? Wastegate ? Or are you going to allow exhaust flow from the primary outlet into the secondary inlet ? A big concern I have is overrun on the primary. Certainly a 25cm^2 housing is gigantic and I'm not over running my 351 on a 5.9 but I don't have a 551 in compound. That is a toooon of air n power.

IMHO I think twin is the best application for these VGTs. Single controller, simpler piping. Combined airflow. The idea behind compounds is to get a giant turbo going and I get that. But 2 351ve's is like 120lbs/min of airflow....... That's more than a single s400 which is 115lbs/min. Now think you do that with 30-35psi, not 75psi... I just think it's the best route and it's what I plan to do to my vehicle if I ever get the chance.

Comment:

It sounds like this is something you're going to have to develop yourself to get it to work right...

Response:

I totally agree that this will need alot of adjustments after the initial install and need to be tuned post installation.. (just needed the unit with the basic setup and we will tune from there)
 
Comment:
I don't get the purpose of the brake sensor and the need to dump boost, nor do you really need temp sensors for oil and water on both turbos... the HE351 has a built in temp sensor for the coolant, and that's going to be really close to the oil temperature anyhow... You may want a temp sensor on the compressor outlet to control water flow in an air-to-water intercooler though.

1. The brake sensor was meant to respond to hard a beak situation...  (you never know which idiot will swing out on you)

2. The air temp sensor will be used for the water to air cooler (was just hoping not have to run it on full all the time or manually adjust it).

3. Thanks for the update on turbo temp sensor and the oil.... (first time working with VGTs so forgot that)

4. Funny you mentioned the hx35, I was looking for one but ran into the he551v at a steal......  If i cant get the 351 to high it up i will sell back or keep it for later
    project (the guy almost gave it away)  I really hope we can get it up though

...............THANKS FOR ALL THE FEEDBACK SO FAR...........
