The Dreaded LT1 Optispark

[Sirrotica]

The best way to fix the optispark problem and what I was going to do with my 97 T/A before it caught fire. This system is what GM should have done in the first place.

No. Delteq is out of business and for good reason. He could never resolve his conversion box issues = some worked, some did not. I know first hand.
Difficult to install as well.

This conversion kit is still supported and uses superior, common LSX coils per cylinder.
Very simple and complete install, all that's left to your opti is a loctite screwed on rotor to hold things in place. The optic sensor triggers the spark. The conversion box comes with an adjustable rev limiter and spark retard option.
Best, and last money spent on LT-1 ignition.

Well thanks to this "opti-spark" thread, and the others on PY, I've decided against purchasing a 20k mile mint condition 94 LT1 FBrd here locally. Now I know "the rest of the story" on these late model LT1s.

Glad to know "known issues" ahead of time. And really not interested in converting (taking away originality) systems of an all original Pontiac.

Greatly appreciate the information shared here.

oh, I wouldn't let an opti spark scare you away from a deal on a nice car.
If it fails, like any distributor, you must replace it.
I won't buy another LT-1 f-body just because I pay for labor, and can't leave anything stock.
If I had an original car, any decent mechanic could work on it - and they are great value for what you get in driving pleasure.
