    New Riva engine cooling kit & 3 bar MAP sensor

    I'm assuming these were just released, since both install PDFs have a creation date of yesterday. I wasn't aware of the boost limitations of the stock sensor.

    I just found this out myself. The stock MAP sensor is a 2 bar MAP sensor.

    This explains why those of us with ViPEC or Motec are only logging about 15 psi boost with the Riva E1 supercharger upgrade. The MAP sensor isn't reading any higher than that. Actual boost is higher. I'll get some good logs of actual boost once I install my 3 bar sensor.

    Not to start anything, but then how are some folks reporting way over 15 bar? Had they already replaced the MAP?

    That's a good question. They are probably using a add on boost gauge such as a dynotune boost gauge, etc.

    Ah, didn't even think of that.

    Wait till you see what boost numbers your gonna start recording with the 3 bar sensor....
    This is a must-have item for any1 running a big-boost wheel.....now the Vipec or Motec ECU's will read the actual boost output and adjust air-fuel accordingly....now that they are seeing the real boost because of the removal of the limitation of the 2 bar sensor.

    One thing I don't understand and I guess there is a simple explanation for is a 2 bar sensor only reading what is essentially 1 bar. Then a 3 bar sensor that reads 2 bar??
    Includes 1 bar vacuum?

    Something I'd like to point out is that the Riva Cooling Kit still retains the use of the thermostat. This is extremely important in a high-perf, open-loop recreational application in that it allows proper warm-up during low-speed cruising/no wake zones.....but at the same time allows proper cooling during extended high-speed/WOT runs as well as everything in between.......because now the high-flow billet fittings and better routing allow the thermostat to properly do it's job.

    Benefits of this include proper warm-up/operating temp with better ring seal, better engine longevity/reliabilty,.......and consequent avoidance of any GIO issues.

    Will this actually give performance gains or is this for logging purposes only to show actual boost? Sorry if it is a stupid question.
