I was reading some articles on a prelude website and they were talking about how OBD2 would eventually "detune" any mods. Is this true? Their solution was to install a rocker switch to create the same result as pulling the backup fuse.

They went on to say that any tuning done with the VAFC would be eventually learned by the ecu and "detuned" out. I guess this amounts to a lot of hard work going to waste. Sounds funny

Can anyone vouch for this info?

 

obd2 is just harder to tune
i ran obd2 with vafc and it sucked
kept popping check engine lights
and the car ran really crappy compared
to the obd1
