Aftermarket ECU
Been a while since i posted, just some FYI Haltech has a replacment for the GM tbi ECU that is fully programmable, here is a link
They also have a unit that will run 4 ( high impedence) injectors and has 4 ignition outputs, so you could do wasted spark on an 8 cylinder. It sells for less than $1,000.
A third option if you only want to control spark is the Megjolt Jr.
Less than $200, but you will need to hunt down some parts in the junkyard.
