Will this work on non USA Civics?
This release is for R18 manual and automatic transmission Civics sold in the US. It will not work on Canadian Civics or any Civic sold outside the USA.

Can it eliminate the second o2 sensor?
Yes. The secondary oxygen sensor is used to monitor the catalytic converter efficiency and assist with closed loop operation. For off road racing use in which a catalytic converter is not desirable, the secondary oxygen sensor can be disabled using the FlashProManager software without any negative affect on the tuning or operation of the car.


Every map listed here has been comprehensively tuned for fuel and ignition for both part and full throttle. Listed here are dyno plots of most of the base maps provided with the FlashPro in PDF format. The tests give a good indication of the gains to be had from various bolt-ons.

All intake maps include adjustments to the Air Flow Meter data to achieve optimal part and full throttle air fuel ratios. No intake we tested gave the same air fuel ratio as stock. 

Base maps are included for a variety of injector sizes to support high HP NA cars and forced induction.

Maps for injectors:

  • 185cc - Stock
  • 310cc - RSX S / Civic Si (plug in replacement)
  • 410cc - Acura RDX
  • 520cc - Modified Honda Civic
  • 440cc - RC
  • 650cc - RC

The Acura RDX injectors, for example should provide enough fuel to double the stock engine HP with forced induction. We highly recommend a return line fuel system for forced induction with power levels around 300hp.

The dyno plot here indicates the gains you might see with a supercharger kit. Green line stock. Red dotted line 4 psi, red line 7 psi. These dyno tests were run with a stock cat-back which restricted power.
