I guess, it can only generate a near avarage curve (in best case) for your engine. All engines are different and run under different conditions. You should tune it by yourself.

Yes :) You can write logs and insert markers (hot keys or item in the main menu of SECU-3 Manager). Then, you can manually adjust tables by analyzing markers in logs.

Is there an example somewhere? I have no idea of its meaning.

I can't use it but it can't guess all values for your engine. You can use all values you know about the original ignition.
You can look for them on manuals, you can check the ignition curve by a timing light, if you haven't got a timing light you can discover the timing at the idle by turning the engine by hand and looking at the engine marks while breaker point is opening.
By printing a wheel degree and fitting it on the mechanical advance of the distributor you can discover the centrifugal max advance,you can do the same for the canister adavance.
Here you can find another xls file using values you give.

If I could use it I would have given you the 16x16 chart.
Bye.

Hello.
I took two pictures from a guide. I don't know what the guide explains.
The wheel degree on the distributor.JPG
The distributor.JPG
They suggested me an idea to discover the ignition curve.
It takes something that make the distributor to turn and that let you adjust the distributor speed, a lathe machine,ain't I right?
I know a timinlg light is littler and cheaper than a lathe machine. If you alreday have got it you can try and then rember that revolutions and degrees are doubled on the engine.
Bye.

Im reorganizing all.
and redo relay wiring, but before please check....


is this correct?
I separated add_I2 to Map_s cose I have internal Map sensor
PS i removed r22 for IGN

And If I use
ADD_IO2 as GD_DIR
IE as GD_STP
do I have to add or remove any resistors?

IE is high-side output. You need pull up 1...2k resistor between IE and ground.

excellent! tested and ignition works now.

next problem
I checked 0 angle and strobe shows -3degr. but changing octane correction not reacts. I used real time map.

CE output is connected to relay as GND to invert output as + . my dash needs 12v to activate lamp. but lamp dose not go on .CE is forced to display .
do I miss something?

Thanx
