Link G4+ Monsoon ECU Ford RS Cosworth YB engine Kit with Wiring Engine Loom & Bosch 550cc / 1000cc Injectors & K20 Coils


At BHP we have spent a long time perfecting the installation of Link ECU's into Cosworth YB Powered Cars including the Sierra & Escort RS Cosworth and a multitude of RWD cars (Mk1/2 Escort, Capri's, Anglia's plus some very odd vehicles)

We have now put together definitive kits to bring your YB up to date with a new Link G4+ ECU. The ECU will run individual injector and ignition trim, plus a selection of optional motorsport features like Launch control and Anti Lag. The Link ECU will also come with much better engine protection, which is what is very lacking in the standard Weber, thats pretty much why the engine becomes unreliable when tuned . 

The Cosworth Loom kit includes the following: Link G4+ Monsoon ECU With on Board 4 Bar Map Sensor, Base Map,  Full engine loom,  4x BOSCH 550cc or 1000cc Injectors Mulithole Injectors With Height Adaptors , 4x Honda K20 coil's with mounting brackets, Distributor cover & Boost Controller with bracket.

The Kit we are selling is a comprehensive kit and allows you to sell the following items (Dependant on ECU) to help fund the new install:
ECU, Loom, Ignition Amp & bracket, Ignition Leads, Injectors, MAP Sensor & bracket & AMAL Valve. This can add up to quite a lot of money nowadays making this kit very cost effective.

Link G4+ Monsoon ECU Specification:

The Link G4+ Monsoon is a step up from Link Engine Management Entry Level Atom ECU with some extra features including Onboard 4 bar MAP sensor & Motorsport features such as Gearshift control , Launch control, Anti Lag, VVT Control and Closed Loop Boost Control.

The Monsoon ECU can run any of the above motorsport features however not all at once; it is dependant on the number of limited inputs and outputs the feature needs.

The Link G4+ Monsoon ECU runs the same microprocessor & firmware as the Link G4+ Xtreme. It is fully configurable with no preset Inputs / Outputs, has 32Mb of  Logging Memory, Motorsport features and closed loop fuel if an external device is added e.g Wideband controller.  

The Link G4+ Monsoon ECU has a 34 pin Waterproof Connector, mounting bracket and USB tuning cable & Link Stickers
