Link G4+ Atom II ECU Ford RS Cosworth YB engine Kit with Wiring 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. 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+ Atom ECU With 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 mounting 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, bracket, Map sensor  AMAL Valve. This can add up to quite a lot of money nowadays making this kit very cost effective.
