I had closed loop lambda control on my 2wd cossie.I bought the kit complete from stu at motorsport developments.I had to buy a second hand L8 ecu from a 4x4 cosworth.I took the car to motorsport developments in blackpool for a set up with stu.I covered over 240 miles on half a tank of fuel! It worked really well.I have however changed engines now so the complete kit is for sale if you are interested.It includes the chip for stage 3 (greens,3 bar etc..)modified board,daughter board for lambda,Lambda sensor and full instructions as supplied by motorsport developments.This lot cost me a pretty penny so sensible offers would be appreciated.
