First time Standalone user EMUJ Classic, i have wired up the car myself (Volvo 480 turbo)
When cranking i have rpm, but no spark. New Coil from Beru ZSE 003. While a bit mad because i didnt get no spark i tried different ignition options. The coil was wired up like this Pin 1->12v, Pin2->ground, Pin 3-> ignition coil 1, Pin 4-> ignition coil 2, ecu settings seen in the picture. First they were set to Coil, Coil with built in amplifier, but after that i started changing them and tried all settings.
After that i gave up for the day and the next day decided to test ign. outputs with the test tool. I tried it on a 12v halogen light by connecting ignition 1 to positive and the other to ground. Tried all 6 ignition outputs but no light was visible. Then i used a 5v bulb repeated the test and same issue.
Can someone support me is the testing method OK? Have i probably fried the igniton part of te ECU?
Why should the project matter? I am using test function, this should force the output. My question was orentated towards my test methos if it was correct. Not the settings themselves.
Just make the plug spark with the plug out of the engine (plug grounded of course), or if its too inconvenient to get to the plugs, then unplug a lead from the coil and jump the spark between the coil post and an incandescent test light grounded to the engine.
This way you’ll see the spark strength and confirm coil function at the same time.
Edit. Also, your wastr spark coil has a built in amplifier. Getting this wrong in the software can damage the ECU.
The problem is, that there was never any spark happening. I am running wasted spark as mentioned and yes i have playd with the settings. After trying the normal spark plug removed test. And no spark was happening.
But i want to confirm that i am testing the output from the ecu correctly. Should i give 12v to the light and the ecu will ground it trough ignition pins, or does the ecu supply voltage trough ignition pins. Thst is the only thing i am currently interested in. If i dont know how to test this i dont know what the ecu is doing in “normal” cranking.
Ok so you are using cranking as your test function?
I have to assume then, that you have not confirmed your ignition outputs are properly assigned by using the built in output test in the software first.
When you are doing this you need to KNOW without any doubt, exactly what kind of coil you are controlling or you can fry the built in ignition controls inside the ECU.
Yours is a Smart Coil (with a built in amplifier)
If you have been experimenting with these settings you could have damaged the board.
But let’s assume you haven’t yet.
Using a globe to try to see the low voltage pulse sent to the Smart Coil may not work due to the very short ON time being insufficient to light the globe bright enough to see it flicker. An LED might work better for this but being in a dark workshop may still be necessary.
In CLASSIC there is a Cranking Ignition Output setting. This needs to be set to ENABLE.
I hope I have answered your question.
Remember you are asking for help in an international community. There may be some delays and overlaps between responses due to time zones. I’m in Australia FYI
Mal.
Edit: CAUTION. using an LED to test this output is also risky because the circuit will have no resistance. You should put a resistor in the test circuit if you do this.
I went to the car about half an hour ago, and tried again. but instead of having the ign connected to ground i had it to 12v like it showed in the manual, that i didnt see before.
And the tool i used for testing, I have then on ign 4 and ign 6
So now i need to figure out why the coil was not working, or probably get a new one that has all parameters already in the default config in ecumaster sw.
For cleanliness’s sake i will continue in this thread.
The coil i was using is a generic VAG one for 1.6 and 2.0 engines, 2x2 outputs, built in amp.
So for the engine to work in wasted spark i have to connect the output stages to cilinder 1 and 4, and the other stage on 2 and 3. Fiering order is 1 3 4 2.
But what setting should i use for this type of coil, or any wasted spark coil? I have seen that emu black i think has an option for wasted spark, but here there are only four different options
In CLASSIC you select Coil. For Smart Coil (known as “Active Coil” in ECUMASTER, You select Built in Amplifier.
The wasted spark is set up using the physical output wiring configuration..
The ECU will send a 9v positive signal to the Coil.
The Coil will ground this signal through its own the internal transistor. The Coil will also provide the control ground for the Coil Primary winding.
When this 9v signal is turned off, the Coil Primary Winding magnetic field collapses and energises the Coil Secondary Winding inducing the very high voltage surge that creates the spark.
In Smart Coil setups, the ECU Ignition Outputs send out a positive 9v signal.
So i should still select the Coils options with this one? And i have not yet looked it up but this coil only has 3 pins on the connector, so a +12, ground and signal i am guessing?
I went and bought it today, because i suspected that the beru one was faulty. Now i have bosch 0221503407, because it was in the coil dwell wizzard so i am hoping this will simplify the process
Edit: Bosh’s documentation lists this
Pin 1 Coil 2 ECU Ignition Power Stage
Pin 2 Ubatt
Pin 3 Coil 1 ECU Ignition Power Stage
"This dual spark ignition coil is designed for low-costapplications in 4-cylinder engines.
The Double Fire Coil 2x2 has no integrated transistor and requires an ECU with internal ignition power stages.
The advantage of this coil is that the ECU needs only two internal ignition power stages for supplying a 4-cylinder engine. The Double Fire Coil 2x2 benefits from series production ensuring robustness and low cost"
Went back to the car again. No spark..
Used the settings as above, connected the coil as i mentioned only difference is that i have connected ign 4 and 6, because i have wired them up like that. but no spark was noted. I will attach the log file.
But i am starting to think that there may be some issues with my setup in the software
