Just got an Omori boost gauge (AEB-030) and have a few questions for people who installed them, vendor isn't very responsive for some reason...
1) Boost tap - seems like T-fitting that came with the kit is a bit small for the hose that's typically used for tapping into in '08's cars (NASIOC - View Single Post - SMY and Defi Gauges install - great pics if you want them!).
2) Dimming - since 08+ MY's use PWM instead of voltage variation for dimming and Omori's use LEDs for backlighting - shouldn't these gauges just work without requiring a special adapter that J-spec sells for dimming control (to decrease brightness)? I think stereo harness has two pins that do dimming - pin 1 is simply on/off. Pin 2 on the other hand is a PWM signal (pulses on 12V), might work well. I think that gauge backlight is too bright if it's plugged into constant 12V.
3) Fitment - it seems like I have to force the gauge into the mounting cup, it doesn't slide in at all. Is it a defect in the cup (fixable) or is it meant to be this way? If so it seems like a one-way solution as I can't imagine being able to remove the gauge later on without damaging it or the housing cup. Also makes little U-bracket that comes with the gauge kinda' pointless.
