  • The DIY kit includes all components needed, including the JST connectors to build the coil pack harness, and the pin header to solder into your ECU. We include extra JST pins in case you break any. You can purchase a crimping tool for the pins, but it is very easy to crimp them using pliers.


How does international shipping work? We ship internationally through USPS, though shipping is no longer free internationally.

What ECUs is this compatible with? This is compatible with any USDM OBD1 Honda ECU. You do not need to have a chipped or tuned ECU to use this. For OBD2 or JDM ECUs, see our external coil pack controller.

My car is misfiring, what do I do? Make sure you are using resistor spark plugs. BKR7E is a popular choice. Check to make sure the board is properly seated in the ECU. If you soldered the header yourself, make sure the solder joints are not cold. Lastly, make sure your coil packs have a good power and ground connection and are from a known good vehicle. Check your coil packs - if one is noticeably hotter than the others, it is damaged. If this all does not work, your distributor may be damaged.

What coil packs should I use? K series coil packs are the most popular. We only recommend DENSO coil packs. If you are on a budget, used DENSO coil packs generally work very well and can be purchased for $40-60 on eBay. You will also need a plate to retain them.
