is ecotrons even in any way related to aliexpress kit ?

Yes, they have on ali 2 vriants of kits. For most of cc it is ecotrons, for other simplified ECU taking in accout only 02 sensor.

What specifically was wrong with the units ? Pump faulires, injector issue, ecu... ? Problems are numerous, unpredictable and each time differs. One my friend burn 16 smartcoils with his Econtron. Sometimes ECU can hang up. Sometimes unprotected ECU outputs burn out. Sometimes loosing fuel output s...

I'm seriously considering converting my gy6-50 to EFI as sort of a test bed for efi tinkering. These aliexpress kits seem to be the only ones ready made for this specific engine. I have ~5 kits from ecotrons abandoned in scrap. A bit more workable is https://aliexpress.ru/item/32767252274.html?spm=...

Just curious, are you planning to implement "Returnless Fuel Systems" says by PWM fuel pump regulation or other variant? Says typical moto fuel pump with 35lph eat 26watt what is too much and prevent use fuel injection on old motos. Or may be exist simple third side schematics? Grateful in...

My engineer made at moment this ECU



One day he will try to place NonoRusEFI to the same case.

It looks like no one with KiCad skills is currently interested to spend time on nanoRusEfi.

Is there easy way to transfer microRusEFI to ALTIUM DESIGNER?

Is that a slightly different enclosure? Why do you not like the original MRE enclosure? I looking for smallest possible enclosure with 32 pins. The box I found is much easier got from Chinese suppliers. It is 35% shorter, 2 times lighter and considerably cheaper, below 10 USD including connectors. ...

Could be a good case for nanoRusEfi is anyone would ever make one! I would be ready to make and test one fitted in this enclosure If I had Gerber and BOM 32pin box.jpg 32pin box1.jpg It is 32 pins. Could be 1. +12V 2. - 3. power ground 4. analog sensors ground 5. IAT 6. CLT 7. O2 8. TPS 9. 5V 10 11...

Please attach as .zip file

Attached. PCB connector and bottom part together. Corrected by factory drawings.

The error isn't split centrally. I corrected PCB and case bottom part according chinese drawings. Fixing holes moved up to 0.45mm. Cannot drop STEP file here. Can correct upper part of case as well (according drawings). When I get real case I can scan and reconstruct it with precision of 0.02mm. Co...

Encountered minor error in connector area of PCB.
The hole pitch = 2.5, not 2.54mm

Just a friendly reminder that CKKB48-1-A.pdf is available in the top level folder of https://github.com/rusefi/hw_microRusEfi This case looke a bit more compact, very strong and light design and could be preferred? https://www.alibaba.com/product-detail/One-Hole-48-Pins-Auto-ECU_60701238041.html?sp...

One semi-mystery is solved. The screws holding the housing bottom to the top do seem to be M3.5 x 0.6. Because M3s just won't cut it and M4s are way too big. I guess. Have a look at drawings of ECU cases produced by https://kinkong-group.en.alibaba.com/?spm=a2700.details.cordpanyb.1.5a4c2693oGwJ0b ...

What features are you after? The most important is substitution of membrane carb for paramotor and 115kg planes. Problems to be solved 1. Most users fly rarelly. When they trying to start engine after break or big themperature change motor dont start. The different reasons, says membrane destroyed ...

We don't have the time, resources, money, or expertise to build something that I would be confident using in an aviation application. At moment for experimental aircraft mostly used http://www.sdsefi.com/ and few similar solution without any redundance. Just bunch of board which serve each one or f...

Is it possible to use on one engine 2 Ecu? If one fault second understand and continue correct operation?
What correct logic should be then? May be already discussed issue?
Or in this case better use e-carburetor which will go to carb "bypass" mode if electronics fault.

jbiplane how would you like to contribute to nanoRusEfi based on tle8080? I should understand what exactly meant contribution in your project . Personally me mechanical engineer who have experience of instalation and testing of existing EFI on small engines, analyzing results, optimyzing engine per...

My next big concern would be the magneto. We currently run alternator. Magnetos are different. No, I use alternator with rectifier and 14V LiPo battery for electrical starter. I think you are looking for a very specific engine with a very specific matching ECU. I don't think a generic solution woul...

I have no idea how to make a PCB survive vibration, I am a software developer. I wonder what would be the temperature if you get closer to engine, our stm32 is only rated for relatively low temperature. What would be the cheapest test mule engine setup with one or two cylinders but high revs? A Chi...

Are you asking to design a custom PCB for your specs? Yes, but I have not interests from my customers to EFI at the moment and any budget to offer right now. I can write clear tech specs of 2level boards which would be accepted by market. EFI solutions derived from automotive industry are too bulky...

To be honest https://www.rcgroups.com/forums/showthread.php?3064770-EFI-ignition-for-RC-engines My company created cost effective and very easy to setup by nonprofessional ECU. SmartEMS suited for 2-stroke and 4-stroke engines leaves a bit of a bad taste: I do not see Speeduino mentioned. Don't be ...

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 PCB? 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...

Why does the ECU need a connector when the leads are really short and everything is so easy to access? If project will successful It will be nice to finally make bolt-on fuel injection kits: - aircraft models engines - 2stroke one cylinder paramotors - 2stroke 2 cylinders engine for 115kg airplane ...

It depends :) There is an option that D-sub connector like picture on your happy picture is not a healthy choice? I am not an electrical guy, I am just spreading rumors here. And a connector would cost a significant percentage of your $100 goal. microRusEfi would be closer to $200 complete with pig...

This 2 pictures are from Speeduino forum The first picture CIMG0931.JPG shows typical Chinese kits started from 250 USD. Cheap, but very unreliable. The second like.jpg shows how it should be. It miss only crankshaft position sensor. 1. Is it possible to make ~Stm32 ECU with 2 injection and 2 igniti...
