Applications

  • K20A3-M1: Revised fuel and ignition values with stock rev limit
  • K20A3-M2: Revised fuel and ignition values with 7300 rpm rev limit

Both these reflashes are based on the performance program in the dyno chart below and vary only by rev limit. VTEC point is not altered.

We do not recommend the use of this reflash with nitrous or forced induction. For these applications we recommend the K-Pro.
