To use or not - YICS Tool

This is the best description of WHY the blanking tool is necessary, even though it's not a normal running condition. In short, you can't get a reliable reading of the strength of the vacuum of an individual cylinder without blanking the YICS.

Moral of the story....the best sync is achieved with a Colortune, a YICS blanking tool, and a 4 cylinder manometer.

Bench Sync, Sync without tool (get it good enough to Colortune), Colortune, Sync with tool, Colortune, Sync with tool, Sync without tool(to double check your work)???

From what I just read it seems like a Colortune is as much or more important than the blanking tool.

Honestly, since we here on xjbikes.com determined that you could just stuff an oily rag in the passage to blank it off, I've always thought the point was moot.

I just didn't understand, until now, why a sync during a normal running condition wasn't going to be better. If we could somehow get an accurate power reading from an individual cylinder without blanking the YICS, then we wouldn't have to blank the YICS!

 

Bingo! Pick any prize from the top shelf........
