what i am wondering is, is it possible to put an Atmo BOV on a 90 - 93 model MR2. The reason i ask is that i know that there is a problem because of fuel mapping which was only introduced come the 94 model.
i'm pretty sure you can only have the "butterfly" BOV (u know the di di di di di noise one ) or a plumb back BOV... i love the Atmo BOV, can it be done without fuel mapping?
