Opti

just a quick question. I have read alot of people saying that you can convert your opti for some msd set up. I have never found anything on saying what you need to do that. So can someone please let me know what it takes to do this conversion, thanks very much, i basically just want to know what parts i need and good places to find it all. Thanks guys

MSD make a full replacement Optispark distributer - a clone of the original, with a few upgrades - in both non-vented (93/94) and vented (95-97) versions. You simply buy the correct one for your car, and install it. No "conversion" involved. Whether its any better than an OEM Opti is still an open question. Try a "search" on "MSD Opti" for more info.

Actually, that would be a "high-resolution pulse missing" code. The Opti generates two pulses (high and low resolution) that are sent back to the PCM. Both of those pulses are generated by the optical module and strobe wheel within the Opti. There isn't any reason why the MSD Optis would "all" have an issue with either the low or high pulse.

I'm running the MSD Opti and have found it to be an improvement over the GM.

In what ways an improvement? Reliability, high RPM performance? Not questioning your opinion that it is better, I'm simply curious.

First, the CNC machined billet aluminum housing is far superior to the cast pot metal in the GM unit. Next is the greatly improved quality of both the cap and rotor (resin, brass contacts, Etc.). Also, the contact on the MSD rotor is machine screwed to the rotor, whereas the GM is sonic welded (melted plastic). Additionally, the GM Opti has “extremely small” rotor screws which are more prone to get loose then the MSD’s w/ #6-32 machine screws. The MSD wiring harness is high-quality, one-piece and eliminates the plug inside the GM Opti that can corrode and cause problems. Last is the internal timing adjustment, which allows you to correct for mechanical error, or add/remove a few degrees if timing for optimum performance.
