    Forum made EFI?

    Yes, It will completely inside of throttle body. Designed to work OK at -45..+85 C. At the moment it is intended for my company engines. I will very careful before promote elsewhere. I will carefully offer it for exportation not earlier than March 2021 or at least 100 units successfully tested...

    Forum made EFI?

    Finally my company ECU = digital ignition + injection integrating to throttle body will look like on this picture. We will make it rather big 70x70mm placing most of components on one side to fit ECU+throttle body in $120 FOB 2 ignition and 2 injection channel allow install on most of 1...4...

    Speeduino news 2 injection+ 2ignition channels 47x25mm board A bit bigger board low-cost and mini-sized ECU for speeduino firmware (45 x 55 mm) 4 high impedance injectors 4 active ignition coils or 1 passive ignition coil with separate ground plane 1 crankshaft sensor with VR-conditioner 1...

    Forum made EFI?

    Yes, I experienced since 2016 with Speeduino, Megasquirt, RusEFI. finally made in house EFI... But after saw 2-stroke Stihl 550i chainsaw which perform exelent using only one integrated crankcase temperature+pressure sensor. It consume just few wats and do same like complicate classical systems...

    Forum made EFI?

    For simple predictable load like propeller not required. RPM would controlled by throttle, engine get as much fuel as required on definite RPM. One simple fuel table (open time vs rpm) will ensure lean mixture at nominal rpm and rich at full throttle to cool engine. Possible make fuel table by...

    Forum made EFI?

    I am in process of development of ECU which will integrated to throttle body 70x70mm board at moment. One sided to make cheaper. I afraid it will take few month to complete. But I have other simple idea - want to share. May be someone will implement or help me to implement. I believe it is...

    Forum made EFI?

    Yes. In general we are customer driven and can change our hardware as required if order quantity more than 20.

    Exactly. For turbo emgines possible atach hose to.

    Forum made EFI?

    Yes, but we can add wideband controllet on board by ourselves At moment we made and testing our cheapest 80USD ECU in non hermetic plastic case which could be easy installed on old cars including ones with mechanical sparks distributor. Next step will be bolt on ECU integrated to throttle body...

    Forum made EFI?

    All existing EFI systems are very redundant. If they dont get signal from definite sensor than use values on default. If some signal missing then remaining sensors permanently make some required corrections. I saw many projects which start as simplified and finally become very similar to...

    Forum made EFI?

    Flame-Power relatively mature product with 50+ sucsessfull instalations and 2 user faults. We are unable at moment provide good remote support outside of Russia due weak logistic, unclear custom rates from both sides of boundary, time shift... Non experienced users messed up ignition and...

    Our company www.flame-power.com made new REAL TIME engine management units with ARM processor based on Open Sourse RUSEFI. It so fast that can calculate ammount of fuel and ignition advance angle each RPM for 1...4 cylinder engines CAPABILITIES Primary VR or Hall input (configurable with few...

    Atached some info about Stihl injection, hope will usefull for someone.

    Forum made EFI?

    Its very good for small 2-strokes. 1. Just one integrated pressure+temperature sensor in crankcase instead of bunch of sensors. 2. Automatic calibration without need of o2 sensor. 3. Ready to immediately work after few years of conservation. 4. Low pressure fuel pump using suchion in crancase as...

    Forum made EFI?

    I tried eventially all existing open source ECU and strongly believe only 2 variant are good enough for use in amateur aviation - Megasquirt family and more modern RusEFI The only thing which could beat everything by simplisity, low weight and reliability is Stihl fuel injection. May be good...

    Industrial engine electronic management system development - HBA style

    We going to switch to much more powerfull STM32 cause it will "real time" Ecu. It will count required ammount of ruel each rpm (not about 5+ like Megasquirt). It will allow direct and clear programing on high level engine like C++ and debugging of ECU without requirement of testing hardware...

    Lighweight opposite 2-stroke engines

    Hi Bille Normally we dont have stock, make each engine in 2...3 months preorder with 30% prepayment. All options like reduction, EFI, electrical start are tested and possible. At moment only one order for max featured engine was finished for UAV drone named Grif-2 which produced in Belorussia...

    Industrial engine electronic management system development - HBA style

    We desparatelly tried improve Speeduino to good reliability, cloned some Megasquirt 2 and 3 of curiocity and finally make own board using same processor like MS3. In Megasquirt schematics we found numerous errors but bulletproof it stil work despite of. Finally we will use as base open source...

    Anyone deal with speeduino?

    Yes, we build about 16 Speeduino-based ECUs before finally abandon any Arduino stuff. Now deliver about 50 test on Motorolla processor (same as MS2, MS3). Now we make 10 experimental ECU on Stm32 processor. I made new site www.flame-power.com where will post some info.

    Adding redundant fuel and spark to auto/sled/motorcycle conversions.

    We are testing solution which manages 2 separate third side ECU including Magasquirt 2 extra. Should be completely tested to this July and sold from internet shop at www.flame-power.com
