have you seen the STM32F407ZG board? I do not understand. STM32F407ZG is a chip, not a board. rusEfi is not a highly loaded webserver, we do not benefit from additional RAM allocated on demand :) At the moment we do not have the code to use extra RAM - we need more software developers to implement ...

Where does RusEFi store all the maps?

rusEfi stores all maps in stm32f* own flash

microRusEfi board has an additional external memory chip which we have not started to use yet.

i am not aware of any aviation plans or discussions. i have no idea what faults should be handled how, i would recommended against flying on rusEfi.

I believe the unusual proposal is in order to reduce fabrication? If one relocates cable-driven throttle, one needs a matching cable and matching throttle body for the cable. If one adds ETB it's easier to fabricate? this case old throttle body at default location with default cable act mostly like ...

TLE8080 could be the basis for nanoRusEfi like needed for scooters and other tiny engines. Something similar to viewtopic.php?f=4&t=1496 but for TLE8080 would help.

@jbiplane how would you like to contribute to nanoRusEfi based on tle8080? Would you be available to design a small test module PCB for jbiplane similar to viewtopic.php?f=4&t=1496?

Please post same exact thing in your vehicle topic and let's continue there? This is on the edge of what this topic here is for in my opinion. I think I know what you are looking for and I think it would work. A picture or a drawing would help just to reduce the chance of misunderstanding :) VNH2SP3...

Also first start with case painted orange!



Sweet MAF oscillation at maximum data rate.

Naive thermal test: Q1 seems to be the hottest component at 20C-25C above ambient. That's with rear side of the shell acting as radiator. Without the rear plate I've seen Q1 at 45C above ambient - 25C+45C=70C on a bench with no load on the MRE. https://youtu.be/QeZ0bujoRjg https://youtu.be/uu4JIkfsXe4

Don't be wrong.

I was going with the information you've shared Thank you for the clarification.

I will continue work with SmartEMS, but going at least try something else before finally choose. At moment I want cheapest possible board with ~24 pins (or a bit more) connector in aluminum cases suited for the most of my engines. What makes you look for an alternative solution? To be honest https:...

Let's begin from the beginning. What skills do you have? Can you solder? Can you mill aluminum? Can you write software? Can you design PCBs? You are talking about a pretty wide range of engines. Where are you with these engines? You assume we can read your mind? We cannot. Is this engine 300 grams t...

You can make microRusEfi cheaper by converting it to use STM32F407VET6 from eBay. I believe there are some main system chips for two cylinder which would be cheaper than TLE8888 we use in microRusEfi.

So go for it!

1. Is it possible to make ~Stm32 ECU with 2 injection and 2 ignition channels under 100 USD for end user? Should work for 2 and 4-strokes I saw numerous attempts like https://www.nanoefi.com lasted for 5+ years, but nether finally sucseed. It depends :) There is an option that D-sub connector like ...

@abricosvw reminded me to run a longevity test. microRusEfi powered from +12 has blinked LEDs overnight just fine!

rusEfi console new usability feature: auto-detect serial port.

please understand how little information you provide. what did you do before this happened? have you ever seen blue led on green board blinking? iz blue led blinking now? can you connect with TS? can you connect with rusefi console? this is probably not a screen issue but firmware or configuration d...

I have questions about troubleshoting Frankenso board. I've one from tindie. Display on board stop working. Is there way how this display can be enabled/diabled? Which USB connector is for connecting Tuner Studio? Please post a picture or record a video since too many different things could be desc...

+12v into each of the connector +5v lines was a success - MRE has survived.

Wiring GND and +12v was a success - MRE has survived.

Looks like we are ready for 0.3

Some firmware progress!

Nope, here is how this is connected. The left resistor was added because LED was pretty bright even in OFF state, barely getting brighter in ON mode. Now with the left resistor, I get proper on/off light.

This style of stitching would require drilling and probably dust But yes that was considered.

Note that only 4 yellow LEDs are blinking

I believe 6 injectors means two MC33816?

I believe we are kind of far from 6 injectors?

I am 100% sure that board#2 (v0.1) used to have both CAM and CRANK channels working before I got TLE8888 damaged (TLE8888 was since replaced and it works now). Now I am unable to get trigger events into the firmware while USB works and LED blinks. Board#3 (v0.2) had bad solder joint on cam stm32 pa...

Personally I do not have force induction vehicles so cannot comment on "how well" - I know a few users have turbos but you would have to look at build threads. GM MAP is what 75% of the users use. Yes it's supported. No launch control in official firmware. There were multiple unfinished attempts see...

As promissed here is the patch file, 25 lines of code ))

@md_sanci are you still interested to add a unit test and get this merged into the official repository?

там кажется цена 5 штук или 10 штук одинаковая?
