I have an Electromotive SDI and Opti eliminator for sale. Works on 92-95 OBDI LT1's, although I believe it will work in stand-alone mode on OBDII vehicles as well. Includes SDI coil pack, coils, mounting bracket, Opti eliminator, crank trigger, LT1 specific coil pick-up mounting bracket, three pick-up coils and all related hardware and documentation.

System works best on 92 & 93 batch-fire LT1's, but works great when the Opti is used on 94+. Will not work well with an electric waterpump - the motor causes interference with the pick-up.

I recommend using this system in stand-alone mode (let the SDI handle the timing curve), especially on large displacement engines. When used in stand-alone mode, it can be used with such options as a 2-bar MAP for supercharged/turbo applications, soft rev-limiter, two-stage rev limiter, on-the-fly timing changes (±7° from inside the car), nitrous timing compensation, etc

The SDI has been polished and clear-coated for a nicer appearance. I will post pictures of it tonight. No plug wires are included, and I make no warranties other than it is in operable condition.

I am asking $500 OBO, which includes shipping. Please e-mail me for more information.

Will also consider reasonable offers.

 

If I had the cash, I'd be all over that.
I can vouch for Curt, I know him personally and is a stand up guy.
