chipped ecu vs control module vs air/fuel controller

[arthaccord]

you could use booth cuz evry car is diffrent and some times the tune isnt 100% and you can tweek it a lil with air feul controller

i read somewhere that air/fuel controllers (AFC, SAFC, VAFC) are useless on hondas because hondas use MAP sensors and not mass air flow sensors

[MRX]

do you have an air fuel controller?

no, i got rid of it after having it on the car for an hour. I'd already discovered chipped ecu's by that time and just wanted to try it out.

The problem with afc's is that to alter the fuel they manipulate the map on the ecu by shrinking the matrix table. Meaning to alter the fuel it has to alter the timing also which in turn is terrible for applications that can't afford any advanced timing.

The solution for the advanced timing is to retard base timing all over the map at the distributor. Which to me is like putting a band-aid over a STD. Sure, there are success stories but i enjoy full control over my engine.


And no, it doesn't matter if the car is operated by MAP or MAF, the controllers are equally operational for both.
