ok. i have a b18b motor that im about to put a turbo kit on.
i also have the hondata s300
when it comes to a/f ratio ive heard of just tuning it from the computer, ive heard of using the PLX system, ive heard that its compatible with the hondata s300, and so on and so forth. what im trying to do is trying to consolidate everything together and figure out what i really need to accurately tune for a/f. engine reliability and longevity is top priority so i guess spending the money NEEDED for the BEST price is desired. i dont want to spend money now and later find out that oh i need that or i dont need that if you guys are understanding what im trying to say. SO other tuners out there or ppl with experience i need your help. thank you

 

Use what ever wideband suites your style/budget. I.E. PLX, AEM, INNOVATE, FJO etc..
You will simply wire the 0-5 volt output from the wideband into your ecu on an input to log your air fuel ratios
