![]() ![]() An MSD SCI, 6-Series and 7-Series Ignition Control may also be used. R57 interferes with the signal from the processor to the VB921, so it must be removed, or else your dwell and timing will be wrong. WARNING: The Blaster SC Coil and Coil Driver produce very high voltage and current. R57 is located about 1 inch (25mm) from the DB37, and 1 inch (25mm) from the heat sink. If you have installed it, remove it (or cut one lead to disable it). To use the high current driver (with the VB921 dedicated coil driver IC), you must install the high current ignition driver circuit at step#65 of the assembly of your V3 main board. Wiring the Coil to the High Current Driver To control 2 coils, such as for 4 cylinder wasted spark, see: The high current coil driver circuit use the VB921 dedicated coil driver device, which limits coil current to about 7 Amps (note that later versions of MegaSquirt may have the BIP373 instead of the VB921). The MegaSquirt-II™ processor upgrade daughtercard, in conjunction with a V3 main board, can control a single coil directly (it still needs a distributor, unless you have a 1 cylinder engine).
