Complete kit contains everything you need to assemble a DIYPNP ECU for cars with the 55 pin Bosch connector. Includes MicroSquirt module and case. Fits many European cars and a couple others. This application list is based on US market models; there are also some European market cars that used this connector not listed here.

• Also- you can click this link for the official DIYPNP Product Page Feature List which includes the above list plus a hardware level feature list (that tells you not just what you can do, but what hardware is available to do it)

 Note:  Some of the features listed above use the General Purpose Inputs/Outputs.

Application List

A partial list of what cars this connector fits is shown below.  For more details including a list of vehicles we have detailed documention and startup maps for, click here.

Note:

Since many of these cars used a 3 wire IAC valve, we've included all the parts needed to construct a 3 wire IAC circuit in this kit on the adapter board.

Also many models on this application list use an internal ignitor so this kit includes one BIP373 internal ignition driver.  You can optionally add up to three more to your DIYPNP for direct-fired wasted spark or COP conversions.

This kit:

Contains everything you need to build an ECU like this one:

This board supports up to four BIP373 ignition drivers which are not included in order to keep your cost down since most of you won't need them for running your stock setup. If your application does require internal ignition drivers (again, most do not) you can add BIP373 ignition drivers to your kit.  We offer a DIYPNP BIP373 mod-kit which includes the BIP373, Heatsink, and mounting hardware here.
