the only changes that I was doing I changed between injector simultaneously or sequential ...
I only have a sensor crankshaft
I don't have a camshaft sensor (he is on engine but i don't use it) ...

I am trying to help here. My question is if configuration got corrupted and I am looking for real latest logs and real latest tune. You are free to help me help you or not help me help you

This is supposed to work funny since you do not have cam sensor but it's supposed to work. Do you want to try un-doing sequential back to simultaneous?

[russian]

You have cranking coolant multiplier set to zero - this multiples your fuel by zero and you get zero fuel.

You have cranking TPS multiplier set to zero - this multiples your fuel by zero and you get zero fuel.

Please set both curves to "1" if you do not want to use those. Please set to something else if you want your cranking to depend on your CLT.

I will check again simultaneous !!!

There is now a warning code for this case

YES
that was the problem
I had a zero there
I changed to one (see photo below )
it started working

to use sequential do i need CAM sensor ?

to use sequential do i need CAM sensor ?

You can run sequential without a cam sensor. However, it may inject 360 degrees out of phase. There's a 50/50 chance of it being correct or "wrong". That said, I ran my engine for 5000mi/8000km without a cam sensor and it set to sequential, and I couldn't tell if it started in phase or out of phase.

tl;dr: you can safely set it to sequential

idle control ...
i have cable throttle body ...
but inside (throttle body) there is also electric motor ...
so 2 in one ETB and MTB ...
ETB is for idle control and Cruise control ...
what do you think how will it work ??

p.s.do not listen to what I say on the video

[Abricos]

maybe anyone have extra time to see the date log
and maybe you see what improvements can be made
I am very interested how to tune Injection Phase ???

I am very interested how to tune Injection Phase ???

For engines like ours, injection phase doesn't really matter much. You will probably get slightly better emissions, cold start, and idle smoothness if you inject against a closed valve so the fuel vaporizes fully by the time the valve opens. I was unable to observe any difference on my car playing with the injection phase. The injection phase table indicates the END of injection, in degrees after top dead center. So -360 means that injection will finish just as the intake valve is opening. Set it to -400 and call it good.

So how do you tune it? You need an engine dyno, an ultra-expensive exhaust gas analyzer, and an unbelievable amount of time.
