- It has 3 modes of course.(static, dynamic, dead time)
Dead time can be found out by holding a car at ~3000rpm switching from sequencial to batch and if the afr doesn't change, then the dead time is set right. (standalone ecm required!)
N-Channel Power Mosfet with logic level gate is used to directly use the pwm output of the arduino.
I have a linear voltage regulator in the case to supply 5V to the arduino.
Very nice build I like how you have the test tubes drain. Well thought out
This is some movie opening material here. I used to be an ordinary man, until one tragic event changed my life and I decided to build this contraption - All while the camera is panning across this mad scientist laboratory looking device. Good stuff.
😄
I love the way you made it so easy to deliver the idea .... thanks a lot for sharing the project ♥
Beautifully thought out and made
Thanks!
Hast du eine Hardware Liste und einen Schaltplan?
Hi, how is the injector coil powered? Just standard 12V + MOSFET in the circuit? I am wondering since I think the coil has low resistance. How many amps does single injector need in peek?
it is around one amp per injector, dc resistance is between 7 an 16 ohms on high impedance injectors-
the driver is a a logic level power mosfet. (q(g) is under 5V; it's a to-220 package can't rember which one it was.)
it has a 10k pulldown on the gate and im using 30V zener diodes as surpressors.
the back emf is problematic as it's shutting off the arduino cause you're draining against ground.
(when you're using a lot of injectors on the same driver)
my temporary(and now permanent) solution for that was using two power supplies, on after the other for the arduino...
idealy u could use a a normal diode in antiparallel, but u cant use a straight diode, because it wouldn't let the injectors close fast enough, the ongoing current thru the coil keeps the injector open. most ecus use the inbuilt zeners in the injectordrivers which are between 20 and 50V.
this is the FET i'm using:

Can you provide the information on the regulator, fuel pump, measuring vials and filter? I would like to build one.
fake tomei regulator, fake bosch 044, 100ml measuring cylinders, random inline fuel filter
Which Arduino did you use?
chinese Arduino UNO
does your linear voltage regulator get really hot over time with this design or is it manageable since you only use it every now and again
no not realy.
load is directly on the source...
@@carlbenz3341 thank you
draw a plan for your audience please, we will thank you for those who do not understand much electronic
i'm sorry, but no.
Hello, very nice work!
Do you have the Arduino Source? woul you like to share it?
Thank you in advance!
Here you go:

Ausgänge sind über Dioden gekoppelt um zwei "Drehzahlen" zum dynamischen Testen zu erreichen. (pfusch lösung. ;))
Ouputs are connected over inline diodes to get two different "RPMs" for dynamic testing. (botch way of doing it.)
Danke dir! Hast du auch eine Hardware Liste oder einen Schaltplan?

Nein, ist auch nicht wirklich was dran an dem arduino.
An den durch dioden gekoppelten Ausgang hängt ein 3,3V logic level FET(mit 10k pulldown), dieser schaltet 12V aus einem Batterieladegerät für die ESV.
Taster 1-4 sind Taster mit pulldown, die den eingang bei betätigung auf high ziehen.
schalter 1 is ein mode umschalter, macht quasi aus vier tastern acht.
dieser schaltet zwischen 5V und Masse.
Die 5V für den Arduino macht ein LM2596 DC-DC board. (eigentlich zwei hintereinadner weil ich probleme mit back-emf hatte)
Aja und Ausgang Drei ist ein Pieper, zum akustischen anzeigen von Start und Ende der Sequenz.
MfG
Danke für die Info!
Das heißt es hängen alle Düsen auf einem MOSFET?? Braucht das nicht zu viel Ampere? (Welchen hast du in verwendung?)

kann bei ~3V gate source, ~30A drain strom schalten.
eine highZ Düse nimmt max. 2A.
Please give me the code
