Hi i know this very much a noob question, i've learned quite alot over the last two months but the whole timing thing confuse's me
but then i read somewhere that for my setup 23* of full load advance should produce good power so what does that mean? i put 23* in the map for full load across the rev range? or work my way up to 23* at redline in full load line?
Do you understand how ignition timing works? Basically, you want to have as much advance as you can without knock. If you check KFZWOP you'll find massively high values - because this is what the ECU wants to attempt to reach, but never will due to lambda, knock etc.
Basically, an liquid fuel engine is always going to be subject to knock, it has to be encountered. Start with a relatively low range of timing values, do a pull and verify for knock (CF's). If you have zero CF's across the whole table, up the row that you concentrated on (WOT?) by 1 or 2 degrees. Do another pull, do you have CF's? If no, up timing.
Keep going until you're pulling around 3-6 degrees on all cylinders and that's your timing set. I'd recommend getting a tuning book, as this is basic engine tuning and applicable to any FI engine.
