hey all! i recently upgraded the air intake with a skunk2 air intake that has 3.5" piping. I ran hondata reflash aswell to see if theres an increase in performance. after a day of driving my emissions light came on and i believe its because of the larger diameter intake, my MAF sensor cant work with it after a while. i know it should be dynoed to really dial it in but i wanna wait on dyno until i can make more mods. is there anyway i can adjust the reflash map to work with that sensor? or should i upgrade my sensor?

You would at least need to datalog to see what's going on. Likely you are pulling much more air and the ecu can't adjust.
A proper tune is the best route. You don't have go to a dyno. There are plenty of e-tuners that could help you.

Derek at imw tuned

Had a etunez calibration before and Derek’s work was a huge improvement everywhere on the finished product.
