Now offering DIY Megasquirt 3 Kits

We are now offering DIY (Do-It-Yourself) Megasquirt 3 kits for customers who would like to develop their own harness, or learn how to modify the boards on their own. For those who would like to take on the project of building your own Megasquirt system, we offer 3 package options.

All of the following packages will come standard with the following

• Megasquirt 3 ECU

• MS3 Blank Engine Room Harness

• GM IAT Sensor and Pigtail

• Tuning Cable and USB Adapter

• Bosch BIP373 Igniter Chip

NOTE TO ALL BUYERS : This is a DIY kit, meaning “do-it-yourself”. This means we do not provide any technical support for these DIY kits under any circumstances. This is for many reasons, some of which are related to specific build practices employed by the user end, variances in wiring techniques, setups, etc. The other reason is this kit is priced as low as possible for people wanting to save money and build their own kit. It is intended for intermediate and advanced builders. We provide free tech support with all of our Plug and Play kits.

The first is a base MS3 kit, without the upgraded X package to run Multi-Coil Spark, Boost/launch Control, etc.

This is the cheapest option as all assembly will be the responsibility of the buyer.

The second package we offer is a PRE-ASSEMBLED Megasquirt 3x v3.57 ECU which is fully assembled from the factory, and will include the “X” expansion board. This package is a MUST for those who may be considering multi-coil spark, flex fuel, boost and launch control, as well as many other expansion options.

All of the following packages will come standard with the following

• Megasquirt 3 ECU

• MS3 Blank Engine Room Harness

• MS3x Expansion Harness

• GM IAT Sensor and Pigtail

• Tuning Cable and USB Adapter

The third package we offer is an extension of the first two, which for an additional $100 we will provide a blank, weather resistant fuse and relay box, as well as all necessary NEW electrical connectors needed to wire up your Datsun. This includes the following

• All 6 Fuel Injector Connectors (EV1, EV6, Denso, etc)
