My check engine light came on and i took it to the shop. the paper said --manfacurer control and --Fuel air metering which im guessing has to do with the A/F ratio. my mods are aem intake, dc headers, apexi exhaust, koyo radiator, MSD ignition ex coil and cap, NGK plug wires, plugs and VAFC. my car dosent feel like its very efficient so i guess i jus need a good tune. any suggestions to what is going on and if i need a hondata or somethin like that?

 

Sounds like its a 96-00 HX or some other with a 5wire O2 sensor that took a ****.

What car and engine do you havE?

 

Technically you dont need a tune with mods like that. Sounds like an o2 to me..

 

i have a 99 honda civic si B16

Well i did jus have a new cat put in about 2 weeks ago b/c it went bad
