jaymdee Posted August 17, 2006 Share Posted August 17, 2006 ive read the article on the greddy fuel cut defenser.... it does axactly what i thought - which is ok - BUT my question is HOW does the ecu keep the AFR correct when the engine is working hard ' on boost' when its only fuellng for 0.8 bar boost say... i know its got closed loop fuelling with the o2 sensor BUT surely that is only a narrow band sensor for keeping the ARF right when at idle or on cruise - when at WOT conditions, surely the ecu needs more inputs than a fixed (simulated) airflow voltage? do they have a MAP sensor aswell as a MAF sensor? Hi mate, nice Cossie. Whilst I'm not really clued up too much on the techie stuff, I believe the stock ECU is capable of fuelling the car to 1Bar boost. However, the Supra runs very very rich, so at 1.2 bar boost, even though the ECU is only fuelling for 1Bar, you will not run lean. The Tech section should have all the answers J Quote Link to comment Share on other sites More sharing options...
