Scope says 0 RPM and injection angle control understanding

V3 SOFTWARE
1

Hey guys!
I’m trying to start my engine and nothing works, and I noticed that the scope says I have 0 RPM, but the log file shows that i have rpm. Does it matter? Btw, it also syncs, and I have ignition, etc.
I just wonder.
Also, on the example picture of the scope i can see the angles between cam pulses, but that also doesnt appear on mine. Is that because of my trigger type?

The other thing that is confusing to me. The injection angle help guide says that 0 degrees is 720, which is basically 0 again and 800 is 80 because we start from “0”again, i get that. But i wonder.

If i set the angle as 400 and the angle control as “end of injection” then it actually fires injector 1 at 400 degrees before cylinder 1 TDC as the spope says? or if i want the end of injection to be 400 degrees before TDC then i have to type in 320 because that is 400 away from TDC?

The point is that my RB doesnt start, in the V2 base map it has 400 degrees, but that is tied to another cylinder’s ignition event, and in V3 now, you pair the injector to the same cylinder, so I don’t know how that would correlate to an ignition event, and thats why i am using end of injection as control. Well, i would like to use that either way, but for me this is quite confusing.
Tho if I did it right, then i have no clue why is doesn’t start.

try to look for a base map that will start the car the work on from there

My map is based on a base map from V2, i just added some stuff and corrected things that would not work with V3.

Tho next time i’ll go back to V2 with a fresh base map and try that.

The RPM on the scope are calculated based on the selected area.

Your scope looks good. You should check the timing with the lamp.

If the timing is ok you need to select invert phase in firing order.

Thanks, I didn’t know you have to select it :sweat_smile:

I checked it with a lamp, it’s firing at compression stroke, perfectly in time. Or at least I think that is my compression stroke, I will double check it and play with the fuel settings cause it also smells rich.

Sometimes it fires one or two cylinders but it’s not even close to starting.
