Let's fix the tach next, then you can set base timing.

Totally agreed. Its the next thing on my list. Budget for the year is gone. Will have to wait til spring.

Quick question. Does increasing base idle make it difficult to set timing properly since revs are now higher? does there need to be a proper idle speed so timing can be set? I ask because I believe when engine revs go up, the engine will advance timing on its on. This may not be the case since I am not increasing the idle by much?

thanks

Trying to adjust timing to make up for idle changes or possible idle issues will be a bandaid on a stabb wound. Will probably cause some valvetrain issues at some point in the timing curve. Gonna go against my better judgement and guess that it will give you some valve noise or worse around 4000-4500 rpms. Not that familiar with the sr's but i did the same thing on my ka to make up for a wore out iacv and at about 2800-3000 i got valvetrain noise and a little loss of power. I would set base timing and try to get a nice smooth idle that you can just barely feather the clutch and get your car moving without giving any throttle at all. If that makes since to you. KA has a little more torque and it idles right at 940ish and i can do it but i dont like dragging my clutch out like that.
