Fuel adjustment

I can't seem to find a fuel cut controler. The one I'm looking for is the one thats a little black box with I believe two small connecters. Can someone give me a link or somthing.

I think what you are talking about is commonly called a fuel cut defenser. They are sold by Rotary Performance and Mazdatrix. Mazdatrix calls theirs a fuel cut out switch, however. Following are URL's.

Rotary Performance http://www.rx7.com

I checked those sites and I couldn't find what I'm looking for. It's a little black box that has two wire harness adapters comming out of it. I saw it before on some site with a free flowing 40+ hp gain exhaust or somthin' It looks like a tiny adapter thingy. As for making my own I read that info and I don't want to bothered with it and it is far too cold outside to go trial and error style.

The FCD lies to the ECU, making it think it is seeing less boost than the turbo is actually generating. DO NOT run one without making suitable modifications to increase fuel delivery to the engine.

Using a FCD wrong=blown engine.

Be careful running an FCD if you're on the stock fuel system.
