MegaSquirt Ignitor Upgrade Service

If you need to replace your burnt VB921 ignition drivers, or replace them as a preventative measure, SymTech Labs offers the perfect solution! Our ignitor upgrade service includes the necessary parts and labor to upgrade up to two of your MegaSquirt ECU's internal ignition drivers. We perform this service on any MegaSquirt ECU, not just those built by SymTech Labs!

VB921 ignition IC's are antiquated, difficult to find and frail, while the ISL9V5036P3 IGBT's do not limit current to an acceptable degree. SymTech Labs exclusively uses the automotive-oriented Bosch BIP373. These ignition drivers limit peak current draw to 16A, and 11.5A for long dwell times to prevent damage to the ignition coil. They also feature thermal shutdown to prevent destruction from overheating.

You can find more information about the BIP373 by viewing its datasheet:
