i bought my ep with the jrsc kit, also has a hks catback and reflash, it keeps throwing a p0172 - fuel system too rich

the car had a test pipe so i installed a know good cat with know good af and secondary o2 sensors, tested map, injectors and also no vac leaks

was wondering if any others were having similar problems, fuel mileage is terrible apx 16 mpg, hoping to fix without getting kpro because i dont have the money right now, however im convinced thats my only option

The only way to properly tune this will be to get the K-Pro.

that's what I figured, I finally have the money for the kpro upgrade, talking with a local dealer (evans tuning) he said to buy kpro threw him and send my reflashed ecu to hondata, but you will be closed til 2014? is that correct? if so I can purchase off his site just not sure where to send my ecu

Follow whatever isntructions the dealer gives you.
