Hack thought for MAS system???

>From what I have seen even if you lower the voltage on a MAF you still are
restricted by its physical diameter, porting can help to a point depending
on the style of MAF. If you lower the voltage that the MAF tells the ECU,
then the ECU is not going to compensate with enough fuel, and you may run
lean or detonate. The ECU has to be told about the reduction of voltage to
match the increase of air flow that is possible.

If you install bigger injectors that dont match the response time of the OE
injectors or if you go too big and the injectors are too slow then you can
run into mixtures problems. The ECU needs to know the properties of the
bigger injectors.

That can work too.

HEGO? What does that stand for?
