I'm brand new here and I would like to know about tuning. I have a '97 Grand Prix and its easy to connect the autotap up to it and scan it and see whats going Mainly 02 values and knock retard. On an RX-7 how do you watch air/fuel to make sure you are not too lean and how to watch out for knock ( I assume it has a knock sensor). THanks for the help!

 

You can buy a sensor that monitors air/fuel for less than 100 dollars. But then again, you get what you pay for. Racer wholesale supposedly offers such a sensor for about one hundred. Also, amazon.com offers an rx-7 performance handbook that has a lot of good general information. It's only fifteen bucks.
