Espero spark timing adjustment

Hello friends and greetings from Romania!

I have looked everywhere and I can't find the information I need. I want to adjust my spark timing, and I have no ideea at what angle BTDC it has to be. From what I've seen, I have a mark on the harmonic ballancer (the big pulley where all the accesory belts connect to the crankshaft, I'm not sure that's how it's called) and a scale on the timing belt cover. Autodata and some pdf file I found say I should set the timing to a different mark, something like a pin, way more to the right. Autodata says I should adjust to 15 degrees, english pdf file says 8, and the service manual does not mention anything. The ecm gets the lowest spark timing advance value at 8 degrees, but can you confirm that's the value to aim to?

Also, I will have to make the ECM hold the ignition timing steady, not to bounce from 8 to 16-20 degrees as I can see on the laptop. Any ideeas of how can I do that?

The timing lamp is DIY, pretty simple, it cost me like 2 euros and it took me 30 minutes to assemble it. I can share schematics, or you can find them on google if you want to adjust your ignition systems too

Thank you for your time and sorry if I made any mistakes, english is not my primary language

I've got it all sorted out. I'm replying to leave some info here for you. You need to start the engine in diagnostic mode (wire between A and B in the diagnostic plug) and the timing will not change. My car started bad, third try only, i believe fuel pump does not work until you start cranking this way, but I got it started and adjusted the spark timing. 8 degrees BTDC, all is good now. I don't know when I'll be logging in here again, I can't understand anything. If you have any questions for me regarding this, or diagnostics software/cable, or just anything, email me at ionita.mihai01@gmail.com

Hi,

first : timing belt must adjusted correctly in it's right position

mark on timing wheel must be in accurate position, both on wheel of crankshaft ,also on camshaft

After spark-distributor can will send spark signal for ignition at right time

That's all.
