What is better Hondata or apex-i Vetc controller??

 

I hear Hondata is really good.

 

definitely hondata. its can control ignition, fuel curves, rev limit, and vtec engagement and can pin point everything a lot better than a vafc. but for minor modifications hondata isnt really necessary and a vafc will do just fine...depends on the car

 

the Hondata controls ignition and directly fuel injection with no upper limit for increases, VAFC indirectly changes the fuel by adjusting the MAP input signal (why it's called a piggyback) and does not control ignition timing... Hondata sets rev limits, VAFC no such control

 

the ? you should ask is whats cheaper?

hondata is expensive compared to a v-afc
but hondata 2b is good for the money and it comes with a boost option

 

Hondata and tuned you cant go wrong

 

Umm, what good would a VAFC be without tuning?
they both require tuning.
