Hi there I need some info on closed loop lambda control for my 3dr cossie.I know what it does but is anyone out there using it and does it give the benefits that it is claimed to do? how much did it cost and who would you recomend supply it? many thanks.

 

i think stu at msd is the man to speak to, try a search if you havent done so allready, i read a great write up on here regarding this subject, has convinced me to go closed loop on my mk1 cossied escort when its finished

Ste

 

you will need a L8 ecu with std ford babyboard, as there is not enough memory in a L1 to write the code in the run program that the ecu uses.

putting a L8 ecu into a 3dr also means you need the pf09 tps to be matched with the ecu and the 2 outer wires for the tps swapped around.

if you get an L8, get back in touch and i can tell you where to have it done

hth.

 

the output of the lambda sensor needs to go to pin 2 of the ecu. the other 2 wires on the lambda sensor are ground and 12V power supply for the heater.

 

Will the standard l8 chip run llambda?

 

yes if it's from an ecu originally fitted to an engine with lambda and cats (green top late sapphire 4x4 for example).

generally, most modified chips do not run closed loop fuelling although they can be made to do so

 

thanks for your help

 

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.
