hi :lol:
i have HF predator engine 212cc which was in the original carburetor ...
now it's converted to efi ... I connected a standard set of sensors ... MAP, CLT, IAT, ignition coil, fuel injector,fuel pump , fuel regulator,ETB,VR sensor ,36/1 trigger wheel ,electric starter ,cylinder pressure sensor, ECU RusEFI MRE ...
trigger wheel mounted as in the picture ... when piston in TDC position tooth #7 and VR sensor (in one line) ...

Now I need to make an ignition and fuel map ...
I found another my mistake ... my trigger wheel location on (power takeoff - the output shaft) and that means trigger wheel spinning Counterclockwise :( :( and that means right now all mirrored :(

Engines are supposed to start if
1) fuel
2) spark
3) compression
?

1.fuel Yes we have injectors spraying ( maybe not enough )
2. Spark yes
3. Compression good
the video shows smoke from the muffler ...and periodically shoots ...

I'd say ignition timing could be wrong?...
what are those red and green dashed lines? what's no_pin event in the bottom?

Even if you have sexy Yamaha R1 titanium exhaust on your harbor freight predator EFI - do not touch it!!!

I like that as a moto. "rusEFI, don't touch your sexy exhaust" I think that be a great bumper sticker.

I installed the CAM sensor (Hall type)...
the sensor is powered by 6 volts ...(separate power source)
I make a couple of screenshots ...
I think that CAM sensor shows me the backward ...
or am I doing something wrong ...
in TS VVT position guage indicate 610 (what that mean ?)

Both images show only one VVT cycle. Would be nicer to see two or three cycles - to do that, please increase sniffer size on the bottom of the engine sniffer pane.

VVT input does not count like "cam" on our trigger page :( It's impossible to understand unfortunately but you need to say "4 stroke without cam"

i switched to 4 stroke without cam sensor
after switching (with and without cam sensor) rpm go double down
with cam 1285
without cam 628
and as I said a week ago after update MRE new bundle using ST-link ETB only work after type in console (set_rpn_expression 8 0)

Maybe I should simply prohibit BMP pictures because this 3Mb size versus 30Kb images is just painful.

Looks like everything works as expected?

Nick is trying another approach to combine spark plug with pressure sensor glow plug.

Taking smaller spark plugs apart is part of this project. @andreika has pointed us at 10mm and even 8mm thread size spark plugs, see Image

hi
Today I had a small incident :D
chip marked TLE8888 blew magic smoke but continued to work stably ...
the only problem is the fuel pump is constantly working when you turn on the ignition ...
roughly burnt pins on Tle8888 BATPA,OUT23,OUT22 from 48 pin connector pin 33 (GP out 3 )
maybe I did something wrong with connecting the generator or this is the first version of the MRE board ...

Hand crafted chip. Cool to see how it still works.
