DIYAutoTune High Current Coil Driver with Hardware and Mica Insulator

Coil Driver Kit

5 out of 5 based on 1 customer rating
(1 customer review)




Note:  This part supersedes the Bosch BIP373.

OnSemi EcoSPARK IGBT, perfect for use as a high current ignition driver and can be used as Q16 in your v3.57 or v3.0 MegaSquirt build.  This is the same high current ignition driver as used in many of our current ECU products as well as the QuadSpark ignition module, after Bosch discontinued the now infamous BIP373.  Our testing has found that this OnSemi part is a durable and powerful ignition driver.  Installation is identical to the BIP373.

We recommend not mixing and matching different brand IGBTs.

For the DIYPNP, use part number DP-CoilDrvr.

Where do I install the transistor in the MegaSquirt?

  • You can mount them to an extra heat sink above or below the main heat sink, or bolt them to either the case lid or endplate.

Can I use them with an MS3X?

  • The MS3X spark outputs are hard wired directly to the DB37, and a case with an MS3X inside is already fairly crowded. We recommend using an external ignition module with the MS3X like our QuadSpark four channel module instead. You can, however, install a single BIP373 on the main board for one channel direct coil control.
