Hi Karel

Thx for the video's. They are great.
Kopie is also an Dutch word , i am from Antwerp Belgium.

It is a pity that there is no injector phasing/rpm table in the emu .Only fixed.
As on high rpm and high boost the phasing should be quite different to low revs and idle.
You can see also higher up on the table from original marelli ecu.
Sho what can you advice ? Directly after TBC before exhaust stroke ?
How to set up in ecu ?
I have wasted spark and set up ignition 2121 output to ignition event.( switched output from picture )

If you want to achieve another injection time, do it in injectors order, not in ignition order.
But in your case:

In idle areas you have duty like 5-10% and it matter when you inject. But in high torq or high rev, when you have 100% DUTY or almost.... you are injecting all the time, so there is just a short pause in 720°, and i think it does not have any influence on power

Hi
"If you want to achieve another injection time, do it in injectors order, not in ignition order."

Yes i know this but i have found several different injection phases for a 4 cyl engine.
Can you advice me on a correct one ?
For the moment i used this one.


But i don't think it's ok.

[Karel]

Lets think your firing order will be 1342 ? (i know you have waste spark 1212)

so if you want inject 180° earlier, your injection order will be 3421 ....easy ?

[PBU]

Yes, if you assume the spark events are in sequential order and not an event 1 2 3 4 assigned to cyl 1 2 3 4.

Hello,

Still having trouble with the "bangs".

Made the adaptation with 2 resisitors as given bij Jakub.
It's still the same.

On the ign log i can see that the Cam teeth count go's from a steady 8 to 9-10 when the banging occurs.
After the installation of the filter( 2 resistors) it's still visible on the log.
Little spikes going from 8 to 9-10 and then when i release the throttle back to a steady 8.
Also when injectors are not yet full DC.
Sensor in the dizzy is new.

Is the faulty teeth count a reason or the result of the spikes ???

Any advice welcome.

Looks like a primary trigger noise.
This will cause such car behavior....

How did you connect resistors ?
You can try to use pulldown 1K or less for both cam / ckp signaln.
Or several K to +5V (pullup).
Your engine has very noisy sensors and sometimes it is required do use some resistors.

What firmware version do you use ?

[PBU]

Hello

This is the schematic i used. Got it from Jakub.


The firmware is the 1.062

Here is exapmle of spike.At the bottom you see the tooth signal jumping from 8 to 10 ?????

[Jadzwin]

In my opinion the problem is noise on primary trigger.
I would try pulldown resistor 1K between signal wire and sensor gnd.

[PBU]

Will do the test.

[PBU]

This can't be caused by bad separation between power gnd and ECU gnd ?

[PBU]

Placed resistor of 1k between signal and gnd on the prim trigger and car won't start any more.
On the scope i can see primairy trigger is completly faulty.

[PBU]

Removed the resisitor , placed and adjusted a new crank sensor, set the spark gap from 1 mm to 0.8mm and connected the ecu power gnd via a new thick wire to engine gnd.
Problem , for the moment, gone.
No more sputtering.

[Jadzwin]

Great!

The resistor 1K was too small that was the reasonn that the engine didn't start.

[PBU]

Yes , sadly i should have adjusted 1 parameter and do a test.
So i could see what the reason was but i did all to be sure.
For the moment the engine is running ok for 80 %
The resting 20% will take alot of time to get perfekt i think.

1) Is there a more up to date manual available ?
The current manual is far from complete.
Almost nothing on boost , the new idle correction tables , PID regulation, .....................
2) Is there a way to slow down a little bit the lambda regulation ? For the moment it's a bit to sensitive i think.

We are working on context help for EMU. Actually we have almost finished Polish language.
When we finish we will translate it into English. Below there is sampe screen from Context Help.

For EGO Feedback just modify PID parameters kP, kI and integral limit

[PBU]

"For EGO Feedback just modify PID parameters kP, kI and integral limit"

Can you advice on settings ? Is it not the" D" factor to slow down, damp , reaction ?

The polish file would be ok. I can google translate

[Jadzwin]

If the reaction is to fast decrease kP, kI and make integral limit small (eg. 10).
You need to make some tests. In general if kP and kI will be too big the correction will oscilate, if too small it will be very slow, and can never reach the target.

New software version will be on monday so if you download you will be able to switch language to polish and use context help for functions where it is already added.

However I doubt that googla translate can cope with Polish language :):)

Little update:

Did some more adjusting and had 2 rpm drops ( in 35 minutes ) at idle and low revs now.
2 times the tooth count jumped from steady 8 to 16 ???????

I got an working emu file from a college cosworth driver and the trigger settings are different ??
I will post picture later on.
