MS3 Pro Sequential Injection + Coil near plug conversion thread

batch firing 8 (4 pairs) injectors with a microsquirt is another cheaper initial investment option ($370 ecu/harness). unless you're trying to max mpg cruise with some giant injectors, batch firing doesn't have any real negatives. it doesnt have as many extra inputs/outputs and ms3, but probably more than you need for a carb retrofit.
