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

Good morning,

Above all, excuse me for the faults, I am French and a bit lazy with languages.
My name is Cyrille, I live in the south of France.
I have a 1998 Subaru WRX which drive perfectly with an Apexi Power FC, but I would like to try the Speeduino for the challenge.
I have been registered on the forum for some time, I bought a Speeduino v0.4.4c some time ago with a max conditioner.
I made a harness to adapt to that of the car.
I managed to calibrate most of the sensors.
When I make a log of the composite logger, I have a signal that appears, but on the Speeduino board, I have no LED which flashes, while with the hardware testing, all the LEDs flash.
My wheel model is Subaru 6/7.
I tried several things but nothing or done, if someone could give me a road to follow, I am a little lost.
I joined a log of the composite logger.

Best regards

You may have a problem with noise. The very small teeth in the log file could be electrical noise. You may need better shielded cable between the sensor and Speeduino. Remember to only ground the shielding at the Speeduino ground.

Please can you try again with no spark plugs in the engine. Also stop the fuel injectors. This will give a log file with no compression so we just see the tooth timings.

Can you do a log for tooth logger and composite logger.

Do not worry about your English, it is FAR better than my French :D

a long time ago i also thought the Subaru decoder had a couple of problems. Whilst you get a good trigger log. I'll double check my worries.

edit to add, I've double checked, do not use "Re-sync every cycle" i think its wrong.

I will do a test as soon as you ask.
The tooth logger shows nothing.
thanks for the help

I'm sorry, I'm starting with TunelStudio.
What do you call a "normal log"
I mean "data logging" on the main menu, rather than 'diagnostics and high speed loggers'

Hey Cyrille :D

Your English is fine :)

Just a heads up. Logs (data), and tunes are always posted as pairs. :)

Generally, if we can look at tunes an logs, we can either correct issue in the config, or we can say we cannot see any issues, and that then may points to a hardware issue. This we can also make suggestion for. :)

Happy tuning :)

Good morning,

I did other tests without more success.
I joined the PDF I used to wiring harness .

I detail the way you have plugged in Speeduino.

For the crankshaft sensor:
B136 PIN 10 SIGNAL + to PIN 25 Speeduino
B136 PIN 9 SIGNAL - To Pin 27 Speeduino

For the camshaft sensor:
B136 PIN 8 Signal + PIN 24 Speeduino
B136 PIN 9 SIGNAL - To Pin 26 Speeduino

For the sensor shield:
B136 PIN 9 SHIELD to PIN 23 Speeduino

Today I tried by exchanging pines 25 and 24 of the sensors are successful.
I then exchanged the pines 25 and 24 with the pines 27 and 26 without more results.
I then put the pin 9 directly to the mass of the vehicle, without success.
On this car the 2 mass of the sensors are united.

I did the tests with the injectors and coil disconnected as requested.

There is something that surprises me, during the log composite, if I unplug the camshaft sensor, I always have the 2 signals.

Sorry for my long speech, but I try to be as precise as possible.

Another thing, data logging generates an MLG file and I cannot reach it.

Cordially
