Can anyone with first hand experience tell me, what kind of reliability issues do these have?jbiplane wrote: ↑Sat Aug 17, 2019 6:14 pmThis 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 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.
2. Very good option many want to use starter gear dents for pulsing signal. An additional signal can be taken by different methods.
3. If ECU will small enough it can be placed on throttle body minimizing harness.
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.
