You don't need any sort of aftermarket device or special chip to have full spark control with a MSII. You just need to load the right software on it and build a simple circuit. However, MSII is really only for really dedicated enthusiasts. It is complex, lacking in proven 2GNT installations, and still full of bugs. You or your mechanic will spend hundreds of hours researching, modifying, troubleshooting, and tuning to get the full benefit. I think swapping in a MSI chip would be a better choice for you. It is simpler, with lots of proven 2GNT installations, and most of the bugs are worked out of the software. I started with MSI and later switched to MSII. I had alot fewer headaches before the switch.
