bmw e46 Control Panel with ShiftLight

UPDATED 15.12.2019
Hello guys, i want to introduce you device i have made for bmw's with m54/m52tu engines (ms43/ms42 ecu). This device can display actual data, like:
RPM, Mass Air Flow, Ignition, Injection, Radiator temp, Intake Air temp, both of knock sensors, intake and exhaust cams position, actual speed of your vehicle, also it can measure acceleration of your car, and you can force open thermostat and switch e-fan on if you need (by pressing button on the screen), all vanos data, allows you to reset engine adaptations (like idle speed, lambda, variants and etc). Also its supports cars with automatic gearbox, so you can control ATF temperature.
You can connect external sensors: Exhaust Gast Temperature, AFR (mine is Innovate lc-2), Oil pressure Sensor, Boost Sensor.
Price for device is 490$ USD for standart version and 590$ USD for shiftlight version. More you can watch in the video.

Nice device dude, looks like a few hours spent with the programming. So what do you think, how is the pricing going to look like?

Sounds very good!
Can you tell us something about the reading latency?

For example, if I check hp (I know itís not correct) related to revolutions per minute with obd fusion and an WiFi dongle, you wonít have the number precisely related to revs. Also ignition may have an offset related to revs, so you can only like use it for... checking if there are any values.

So, your display and data logging looks quite impressive to me, I hope it is also quite fast. I know we canít go faster than inpa speed, but itís good to go around that reading speed.

donBogi, one of the highest priority goals during develoment was a high refresh rate, by another words as less latency as it can be.
You have a mistake in your thoughts about we cant go faster than inpa speed. Its wrong.
We CAN DO FASTER, so by this way, my device have refresh rate about 10 times per second. Its much faster than inpa or bluetooth/WiFi dongle (like elm327 and etc.)
Refresh rate of data in my device is maximum that ms43 supports, i reached the highest limit of ms43 can give to us. I think i can tell you this is real-time data.

I think you got me wrong, but you said what I wanted to hear. Glad to hear about the correct priorities!

Iím logging with bmwlogger and I would guess itís all quite the same refresh rate.

I was always looking for this kind of device due to the fact that Iíd like to know about knock, iat and so on.

So props to you! Very nice job!

Thanks! What is "iat"? Also i can add a load value which measures mg/stk.
Tell me which exactly values you want to know during driving a car? (for example knock, mass air flow, oil temperature, etc.)

Load value is great!
I have seen that you also have the injection/fuel pulse shown as a diagram. Is it live? Can you also realize this for ignition? A time scale with 20-30 seconds would be nice.

Well if you have the Inpa stuff in there (as I seen cylinder roughness), thatís almost all anybody would need + load value.

This is a very specific project to work with. I donít know if many people will be interested, but from my side you can produce one for me! And if there is more interest than expected, donít forget me! Cheers

All diagrams have realtime refresh rate! Like general screen, 10 times per second. Every value i can realize as diagram. So if you need ignition and load - i will do it Time scale for full graph from left to right fill - 65,9 seconds. Also you can pause graph by taping on it. And continue by again taping on graph!
Ok, one of firsts devices i will produce for you, by the way right now i am doing a coarse and fine processing of 3d printed cover which mounted with display in vent, and bit of programming work.

Oh thatís great to hear! I have to stop and check the laptop screen every time I want to check ignition timing.

Glad to hear that! Iíll check this thread for updates and then we can discuss payment and shipment

So why do you have to check ignition so often?
Do you got a supercharger?

At the moment I am. I donít have a supercharger yet. Iím trying to figure out how much ign it can handle and at which conditions.

Im a Student at the moment and I just like to know how everything is working for future applications

Is it possible to attach a micro sd reader for permanent logging?

I'd love to have a log of a full month of street usage, just to improve my knowledge how the engine exactly operates.

Very nice project!

Will colors and font be adjustable?

Edit: red flashing display in case of knock?

Yes, i can add sd-card reader, but it may cause in slow work whole system, i should check how it will work
By the way you can use smth like testo or bmwlogger if you really want to know it now.
I can adjust color of the font.
About red flashing display, i dont think its a good idea
