| Spark tune vs cam |
Subject: Spark tune vs cam by sliding on 2009/10/12 12:35:04 Are there any thumb rules that one should consider when making a spark table for different cam. There are a lot of tuners that make mail order tunes. How can they make a good tune without having engine near them? They usually ask for cam specs and from that parameters they are able to make at least start-up maps. In my situation, I'm about to step up from #219 cam to CompCams HR-288-10 cam which has much more duration and even tighter lobe separation angle. I had custom tune from PCMforless for my last combo, but now I'd like to try to do my own tune. I allready have WBO2 (LM-1), so I can check fuel tune, bur I'm really concerned about spark tune. Any information about spark tuning would be appreciated! |
