Every gearhead out there knows that no single ignition curve is perfect for every situation. Sure, using a computer, an expensive program and a data cable you can modify the stock controller’s tune/ignition curve to get you in the ballpark for drag racing, autocrossing, and circle or oval tracks, but you’re not going to get a single tune that makes your engine perform the best it can; it’s just not possible. That’s why MSD came out with the original 6LS Black
ignition boxes. We could install it and then fiddle with our engine’s tune as we hit the backstretch or between passes in an attempt to eke out every single available pony that our engines have to offer. You might be able to do something similar with a computer and tuning software, but you’re going to have to take your eyes off the road for that. With MSD’s 6014 (Red) and 60143 (Black) LS Ignition Control boxes, you simply dial in the preset timing curve that you want and you’re good to go. You’ve got six to choose from with these boxes.
If you’re ignition curve savvy, there’s also the included MSD View software that allows you to configure your own custom tune so you can set everything up the way you want it. The software lets you see the engine temperature (with optional GM coolant temperature sensor PN 12608814) and adjust idle timing. You can also adjust the timing on individual cylinders if you want. Even better, they’re compatible with both nitrous and boost and can be used on either injected or carbureted engines, with either 24x or 58x crank triggers using the built-in 2.5 Bar MAP Sensor.
