electronic ignition

[John Nguyen]

Hi all, just wondering, if i change a stock distributor breaker points to the electronic *pointless* type would i still have to adjust dwell angles or make any kind of adjustments in the future? and do they make this type of system for the FI trigger contacts as well?

You would never have to adjust the dwell angle again. Actually, "dwell angle" is a meaningless concept once you take the points out of the distributor.

Timing would remain where you set it, until the distributor itself started wearing. Unless it slipped and rotated a bit by itself. It is still a good idea to check the timing every once in a while, but chances are VERY good that you'll always find it dead-on where you set it.

AFAIK, nobody makes a substitute for the stock FI trigger points. You're stuck with them. Happily, they don't wear that much--they don't carry hardly any current at all--and the fuel injection timing is nowhere near as critical as the ignition timing. In fact, two of the cylinders always get fuel 1/2 crankshaft revolution before the intake valve opens. That indicates to me that the exact timing of the fuel injection pulse is not that critical.
