if you get the Z1 ecu upgrade..you can just elimnate it.

Their ECU upgrade eliminates that part of the car's computer program. All the AIV is..is an emission control device. It is not necessary since many people neglect to change the filters anyway.

I would just yank all that crap out like I did.

I've talked to Ash about this before on his ECU's and he said he leaves the AIV system in the ECU. He only takes it out if it is requested.
