Here's what makes this kit so unique, and so coveted by AMC V-8 owners. The ECU is factory GM controlled and programmed to the specs of the particular vehicle it's being installed on. Howell preprograms the ECU using your intake manifold, camshaft, and cubic displacement specifications to make a plug-n-play system that requires no tuning once installed on your vehicle. The really, really important part is that special sticker sitting on top of the ECU, and has the letters ARB EO.... This makes your EFI retrofitted engine smog legal, even in the strict state of California!
