Do i need to tune my air/fuel ratio? My friend told me to buy a wideband, but i didn't know if there was any other way to tune my car. It is a 1993 RX7 Twin turbo. When im driving my friends behind me say that i have a RIDICULOUS amount of smoke coming out of my exhaust and the fuel smells too rich. Even at idle you can tell the fuel smells too rich. What do i do?

 

Start by listing all details about your car including mileage and mods and recent maintenance.

Tell us when you see smoke. During start up? only when warm? during boost? Color of smoke?

dutty filta!!!

 

It will certainly help to describe the car and it's mods.

If its got upgraded injectors or tunable ECU, get the wideband.

If it's stock injectors, they probably just need to be cleaned. (not with the stuff you pour in the tank - a real proper cleaning)

You can always take it to a shop to temporarily install the wideband for a few tuning pulls.

 

fuel injectors were leaking. its a 93 rx7. I have 880 cc injectors
