Hi all,

I've got a JDM 1997 Integra SiR-G with an OBD2 ECU. I don't want to spend $$ on mods at the moment (currently only got an Apexi pod filter) so I thought I might pick up a VAFC II and get it dyno tuned to make the most out of it in it's current setup. The thing I'm wondering is that I've heard OBD2 ECU's "detune" themselves to any mods or whatever after a while. Would this be the case if I got a dyno tune done with a VAFC II? Also, does the VAFC II have to stay connected after the tune or can it be taken out? Sorry if these are really stupid questions!

 

VAFC/SAFC are great tuning tool for those who don't want to spend the money converting to obd1.
I've never heard of anything about the ecu detuning itself, in other words, that's what the vafc is for, to piggy back your ecu.
The settings will be stored on the VAFC and it can't be "demodified" unless you mess with it.
The VAFC must be connected to the ecu to be tuned.
