Here are my views and intake in regards to the ProSpeed RDX Injector uprgrade with Stage 2 Map.
So my NSX has about roughly 180K miles and it was due or a Emissions Test for my Sticker renewal for Ontario.
Just before going for my emissions I would from time to time get a random check engine light which when I checked was CEL "43" which via by our NSX manual was "Front Fuel Supply System" which further leads to Front Oxygen 02 Sensor sensor or Fuel supply system (for the love of god please don't let it be a wild goose chase with the Fuel Supply system)
Since I had my Prospeed RDX injector kit sitting in my basement since I first purchased the car ( reason why I never installed it when I first got it was I wanted to give my car a nice shakedown and as well don't want to spoil myself so quickly with so many modifications at once, i figured I would do this mod at a later date. As well I wanted to make myself appreciate my modifications more as I gradually change my car over the time.
So I tackled the install which took me about 3 hours including changing my fuel filter and cleaning up my injector ports prior to the install. Installation was pretty strait foreword with no hickups and or leaks. Started her up and let it idle as per instructions and then went on for my test drive. All I have to say was WOW! night and day difference and boy does she feel opened up! Keep in mind I still had my intermittent CEL 43 on which vary from 15-50K of driving which then became every 5K of driving after 200Km of driving. I ordered a pair of Aftermarket Denso o2 Sensors to have them replaced my old and hopefully it was my bank 1 o2 sensor was at fault and low and behold it looks like it may be the Original 02 Sensors that came with the vehicle along with bank 2 which looked it was replaced by the previous owner with a NTK. Being myself I replaced them both just to keep it consistent. along replacing the 02 sensors I also replaced my Catalytic converters with John's (DaBlackGoku1234) old ProSpeed 300cel High flow Catalytic converters which were already 20K miles old but still looked clean from the inside. After that was replaced reset my ECU and drove it once again... CEL never came back ever since, my NSX was happy and still felt strong like a Bull! no more black soot from the back of my car and she was running healthy.
But the moment of truth was the emissions test. which is one thing i dread on doing with any OBD1 car since diagnoses is never strait forward and most of the time becomes a guessing game to have a passing etest.
SHE PASSED! one shot! and if anything ran cleaner then John's car after 2 years
