    MAF upgrade

    When altering (increasing) AMM size, the load signal from ECU to ICU is off. So ICU is offering too much ignition timing 'cos it is thinking that air mass flow is low.

    Head Work for Fuel Economy?

    Small improvement for fuel economy is gained from exhaust porting. Not much though. Individual adjustment for every cylinder's AFR might give best results. But then you have to install 4 lambdas.

    B230FB running rich

    LHs ability to correct AFR is quite wide, and it can cope high fuel pressure on steady state, like idle. When the load is transient the lambda correction is little late.

    B230FB running rich
