P3 Boost gauage HKS Supercharger kit tap in. - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

So got my HKS kit with the smaller pulley making 11.5 lbs of boost but stock MAP sensor only reads 5.5 max. I picked up omni 3 bar but the HKS can tune doesn't read it. So I order the analog boost tap for the P3 kit just curious if any one with the HKS kit or P3 gauge has any tips.

Thanks guys love the kit and the P3 gauge.

The P3 picks up boost through OBD. You have to scale the sensor in the ECU ROM otherwise the 3 bar won't work period, with the gauge or ECU. Once the ECU is scaled to it, the P3 will have no problem reading it. What are you using to tune it? Any tuner can update the scaling for you. If you flashed the ROM yourself it's very easy to change as well.

HKS can tuned for e85. I ordered an analog boost accessory from PS wheres a good place to pick up the boost reading from the HKS kit? Boost gauge port or Vacuum tap. Thanks
