Ford RS Cosworth Tuning Packages.

The Cosworth engine inside your vehicles engine bay is truly a legend within automotive history. The good news is that with over 2 decades of experience in tuning this engine, we can offer you a number of well refined tuning packages. We can tailor the chip fitted to your ECU to ensure all modifications are accommodated for and the vehicle runs as well as it possibly can.

Our tuning options go right up to in excess of 700 BHP but as I am sure you can appreciate this is a conversion carried our rarely and is so bespoke it simply cannot be printed on a web page as every owner and car will vary in their requirements so we have opted to print only the most common conversions we offer in house up to and including our 380BHP drive in drive out package.

Ford RS Cosworth Tuning Packages

All the conversions below assume the car to already have:

  • A High Quality Free Flow Exhaust.
  • A High Quality Free Flow Air Filter.

If your vehicle does not have these then we can of course supply and fit both of these items at additional cost.

280bhp* Package £629 inc. VAT & Fitting
This package enhances the vehicle driving experience greatly, with the same response as a standard car but a far stronger power band in the mid range. This is reaching the safe limits of the standard injectors and MAP sensor. Runs a 15psi peak, 14psi held boost pressure on a standard T3 turbocharger.

The package includes the supply and fitment of:

  • 280bhp Evolution Chip
  • -31 Actuator

This package enhances the Cosworth powered vehicle even further with the fitment of larger fuel injectors (Bosch 803 Dark Greens), a 3 Bar MAP Sensor to accurately read higher boost pressures and a stronger actuator to increase the boost pressure. An excellent ‘fast road’ conversion that has been tried and tested over the years and is refined to perfection! Runs a 24psi peak, 21psi held boost pressure on a standard T3 turbocharger.

The package includes the supply and fitment of:

ALS? Flat Shift? Launch Control? Closed Loop? Look below for more details on the features...

Closed Loop (CL)
Closed Loop Fuel Control can be added to any of our L8 chips and comes as standard with all our P8 chips.

Closed Loop uses a lambda sensor in the exhaust down pipe to provide information to the ECU to ensure that the fuelling is at its most efficient at idle and up to 4000rpm / 4psi of boost.

This has shown excellent fuel economy benefits and outstanding CO emissions. Save money on fuel and stress free MOT tests!

This excellent feature can be added to any L8 Chip above for only £100!

Anti Lag Strategy (ALS)
Anti Lag allows you to improve turbocharger response time by improving the speed of the turbine when the throttle is closed. this means that when you open the throttle your boost is back harder and faster. Positive pressure can be created with closed throttle on wilder setups! Rally car style pops, bangs and flames are an added bonus!

This feature can be added to your L8 & P8 Chip for only £250!
(Requires Idle Valve Modification)


SPECIAL OFFER BUY Anti Lag System & Launch Control together for ONLY £300! That’s 25% off!

Launch Control Strategy: (LC)
Launch Control allows you to generate in excess of 20psi of boost at around 4000rpm on a stationary vehicle! This feature can be added to your L8 & P8 Chip for only £150!

(Wasted Spark Ignition Recommended to ensure optimum performance of this amazing feature)

SPECIAL OFFER BUY Anti Lag System & Launch Control together for ONLY £300! That’s 25% off!

Flat Shift:
Do you have a gearbox that allows clutchless gear shifting?

If so, we have developed a feature for the L8 ECU that allows you to connect your gearbox to the ecu and program in the momentary lapse of power that is required for a clutchless shift.

Further details on application...

This excellent feature can be added to any L8 Chip above for only £350!
