EFI kit for Acty MKI

This is a kit to switch your carbureted HA-3/4-HH-3/4 to fuel injection. During the development of this kit we have never had a truck not start even when we have had erroneous base settings. This has proven that it is ready to be sold for its number one purpose, curing any and all issues associated with the older carb models. This kit includes everything you need to switch to fuel injection associated with the engine bay. Other things you will need to make this kit work are a high pressure fuel pump such as the walbro 250 and an adjustable fuel pressure regulator. We have designed this kit around the AMP microsquirt ECU which is now included in the price, along with being preprogrammed with a base tune. The harness provided has been expanded to a full plug and play harness requiring no splicing. The necessary oxygen sensor and controller are provided which will need an oxygen sensor bung added to the exhaust. Our headers can be added on which include the bung already installed.
