I want to start my car without using a camshaft sensor, someone who can guide me?

I want to start my car without using a camshaft sensor

Please help me understand why?

Another question - do you have all the hardware ready? Can you already consume crankshaft position sensor signal into firmware? Can you click injectors?

A minor code change would be needed - new custom trigger decode. Pretty easy thing to do for me I would just prefer to know that you are ready to use that not a long term project.

[erikmag]

Yes, I have everything ready and the installation is without the sensor of the camshaft because I was previously occupying another computer that allowed me to work without the sensor of the camshaft.

[AndreyB]

I would need couple of days to make the code change and add new trigger - see https://github.com/rusefi/rusefi/issues/570

[erikmag]

thanks

[AndreyB]

https://github.com/rusefi/rusefi/issues/570 is now done - see https://rusefi.com/wiki/index.php?title=Manual:Software:Trigger#Dodge_Neon_1995_only_crankshaft_sensor

I did not try to figure out what is TDC offset of this trigger, do you have a timing light or can you figure out where should the green line be on engine sniffer to reflect proper TDC location?

[erikmag]

How active is the iac control for stepper motor?

[AndreyB]

Do you mean if it works? It works!

[erikmag]

with a timing light verify the trigger angle offset that was 279, made an attempt to turn on when the phase offset of the injection leave it to 279, the latter is not correct.
Finally on the phase injection map, what value can I leave to make tests?

[AndreyB]

I've added 279 right into the trigger definition so that with next firmware version you do not need this offset, thank you for reporting the actual value!

I doubt you need phase offset at all and you can probably live with default phase injection, it should be good for tests and maybe forever. https://github.com/rusefi/rusefi/commit/cd0e19958ef803f99696b1af254197d0f9277eda

[erikmag]

What else can I verify, if there is an injection, if there is a spark, what else can I see and finally, the warning in question?

[erikmag]

I could not start it without the camshaft sensor, I'm going to try both sensors.

[AndreyB]

Have you seen actual spark on both coils? Do you hear each injector clicking?

Can youpre-warm engine with another ecu? Do you smell fuel?

Pictures show it has sync and it is trying to toggle injectors and coils. It should start without more sensors. It could be about not enought fuel or wrong advance if itt does not start. Do you have startinf fluid? Can you start with it?

[erikmag]

yes, already start with another ecu, pre-heat the engine with another ecu, the coils, work, the injectors work, but it does not start, the time I checked and it's fine, I have varied the pulse of the injectors, very low and I'm going up but it does not start, what I noticed is that when I put the other ecu, it takes to start as if the spark plugs were wet.

[AndreyB]

Can you please post a video of your attemps with a timiing gun?

It's really easy to start a warm engine as long as spark happens at the right time and there is fuel. Car would start with a very wide range of mixture ratio. Timing is probably the first thing to double-check.

[erikmag]

I will check the time and upload a video. I would like to upload my tunerstudio configuration file but I can not

[AndreyB]

test - let's see if I can upload my random CurrentTune.msq. Looks to work, how does it not work for you?

[erikmag]

this is my all project.

[AndreyB]

Any luck with any videos?

If you crank your engine do what RPM do you see? Do you see RPM reliably? Any luck with a timinig light video?

[erikmag]

my log

[erikmag]

I am using a 3-way configuration to control my logic coils, with my other output processor, I occupy a 2n2907 transistor to control the logic coils I have, but with rusefí, to activate my coils, I first occupy a unified 7400, from there I occupy an IXDI604PI and finally a 2n2907, send to request a tc4427 to directly control my logic coils, I do not want to throw in the towel, so I'll keep trying for the part of hardware.

[AndreyB]

While you have trigger warnings going up there is also RPM which seem like cranking. At some point there was 800 RPM - do you think the engine was trying to start or is this a trigger error in your opinion? Any chance for a youtube video of cranking in the engine bay or timing light?

Can you please post a picture and schematics maybe?

Too many things could be wrong unfortunatelly, it must be something simple

[erikmag]

I was recording a video but I saw that there are moments when there is no spark in a considerable time, I feel that it goes by the integrated I occupy. video I have some poor quality but you see the flashes of the lamp. Now I do a schematic and I attach it.

[erikmag]

One doubt, when I gave him self-stimulation, at all times he showed me that he had an error in the timing of the crankshaft signal

[AndreyB]

I am not sure what exactly do you mean. I need exact steps to reproduce the problem please? Maybe a video?

too many things could be very different between how you do it and how I would do it. Need much more details please

[erikmag]

double the hands for the moment with my engine to use it only with the sensor of the crankshaft, I used this same ecu in a 1.8t vw and it works without any problem, that dibertido, I only wanted to ask you in the configuration part of the electronic acceleration body as I set it up, I plan to use a l298n.

[kb1gtt]

I do not understand what you are trying to say. Please use more complete sentences with a more coherent train of thought. I think you are trying to say you have a problem, and you would like help with that problem. However it is unclear to me what that problem is or if you are in fact looking for help.

[Abricos]

I think !!! He ask ???
He want ask if rusefi have options to control electronic throttle body ... because VW 1.8t have electronic throttle body ...
And that why he wat use l298n to control throttle body ???
Engine have vvt ...

[AndreyB]

electronic throttle body was never tried on a real car and settings are black magic. we have no experience with it.
