Help with building your Speeduino, installing it, getting it to run etc.

Did read the whole topic, injector settings seem to be alright then.

Now when you run the OEM ignition setup or the speeduino one you get the same problems around 9500 rpm ?

For ignition, the standard control board is now responsible. Speeduino controls the injector.
I did not understand your question a little.
The problem remains crankshaft revolutions, it seems to me that this is a problem in the firmware.

Did it ever run above 9500 rpm ?
I use VR air conditioning version V2.
It seems to have solved the problem: at first I had the jumper JP4. I removed the jumper and the motor began to rotate above 9500, but began to disgustingly work at revs below 9500. The problem was solved by jumper JP2, the jumper is bypassing the VR air conditioner. It turns out that (+) from the induction sensor goes through the resistor 1 kOhm to 19pin.
but still there are some kind of interruptions with a stable ride, it does not matter at what speed.

And are you using resistors R10 and R12
Do you know something about electronics ?
Yes, both contacts from the sensor are connected to the control unit according to the official scheme.
These resistors are installed on the VR air conditioner.
I understand in electronics, but I'm not a super specialist.
I conducted an experiment with battery voltage readings, arduino with firmware 201903 in TS shows a voltage of 12.20 V, but in fact the multimeter shows 12.60 V.
I put on the arduino control board with firmware 202005 and TS shows 16.60V. Made measurements just with the battery connected

Dmitry,

The resistors R10 and R12 are parrallel to the the VR sensor and are there to get the voltage down from the vr sensor especial at higher rpm's
You might try to fit a bigger resistor.

How is the resistance of these resistors calculated?
The voltage generated by the sensor is 3-5V. It is possible that at high speeds it is higher, but I definitely don’t know.

The problem is, there are so many VR sensors each whit its own characteristics.
You need to see them as small generators each whit its own Voltage and Current range.
So voltage and current output depends on how fast your trigger wheel is turning and how many teeth it has.

Trigger wheel 36-1 turns out more voltage than a 18-1 at the same rpm.
Now to "tune" the sensor they are using resistors.

If you make the load higher, les resistance, than the voltage wil drop.
But if you make this load to big then then there isn't enough voltage to run the low rpm's.
Now for you need to find a good value for your set up
Hence the word "tuning".
R10 and R12 are 4,7kOhm at the moment, try a few values below it like 3.9-3.3-2.7-2.2 kOhm
