Timing Adjust?

I already read about this and I know it makes the computer think it's gettin cold air making the mixture richer, but has anyone tried it? I'm thinkin about spendin the $.50 I found in my pocket today. Could this hurt my engine or computer?

I don't understand how making our fuel mixture richer could do any help. Our fuel mixture is pretty rich as is. Too rich, and I think all you're gonna do is bog the engine down and loose HP. One thing you coulddo is goto high octain and advance the ignition timing. Basically, loosen 4 14mm bolts, rotate the whole distrubutor toward the front of the car. What my friend does is he does it by ear instead of a light (waits til the engine starts the detonate and backs off). Here in Cali, we probably can do 2.5-3* advance max cuz our gas only goes up to 91 unless one of us gets brave and fill up 100 octain at 5 bucks a gal and advance fully.

Ok, so how does this work? How far would you rotate the distrubutor? I've never heard of anyone doing this. What would you do about the other cam on the other side of the engine? And would you have to change fuel?

No, not changing the cam timing. I would be changing the ignition timing. Basically bu advancing the ignition timing, I'm igniting the air/fuel mixture earlier (say 13*BTDC as opposed to stock 15*BTDC).

Question

So about how far would you have to rotate it. And would you have to use a different fuel? I mean a different octane? And have you noticed any power gain. Any extra fuel consumption?

I haven't tried it on my car, but have on many customer's car. Supposedly you can get better fuel milage and more power, but you have to revert to high octain fuel.

C25A1guy,
Put a vacumm gage on it and adjust timing to where you have the best reading. 13* BTDC is retarding the timing as compared to 15* BTDC. 13 degress BEFORE top dead center.

Phantom15t,
Don't bother, your C27 is computer controlled timing. Only C25 owners adjust timing.

You know what, you're right. My bad. It would be more like18* BTDC.

Unhappy

So basically I can't change the timing of my ignition. That sucks.

You can, but it takes a bit more work. And you can only change it about +/- 3 degrees on either side of 15 degrees BTDC.

Have you tried it? What's BTDC? Is it hard to adjust? Any change in fuel? Any power difference? What tools are needed?

phantom,
It involves drilling out two rivets, adjusting your timing and putting new lock bolts/nuts on the rivet holes. BTDC = Before TOP Dead Center, measurement of how many degrees before TDC the plug fires. No change in fuel, advancing your timing if your car is stock will require you to use Premium Fuel and very little power difference.

So basically there's no point in doing this because of the little power difference and the higher gas prices.

Before bolting the cover back onto the adjuster, I drilled a hole in the cover. No more cover removal....not that I'd ever have to adjust the timing again.
