Our
first modification involves adjustment of the KE electro pressure
regulator. This results in a fuel enrichment across the entire fuel
range, but can achieve the correct AFR (air to fuel ratio) at higher boost levels. Using this
technique it is possible to increase fueling sufficently to support power
outputs of 200bhp. Any attempt
to increase fuelling beyond this power level using this method will result in
excessive part load fuelling and poor economy.
Our 2nd modification requires some more complicated changes to be made to the fuel metering head and fuel ecu and allows power to be increased to 230bhp whilst still maintaining the correct on boost AFR's.
Our last modification for those that do require more power from the KE system is the fitment of a 5th injector and MF2 mappable controller. We normally use an 803 green injector and 3 bar map sensor, and recommend this system for up to 260bhp. We have managed to use the KE and 5th injector route to power a 300bhp engine but we now advise changing to our Cosworth Management conversion for anything over 250bhp as it produces a more refined setup.
