    Difference between a powershot and ECU reprogramming?

    What is the difference aside from doing it yourself? I assume that the pshot usb's into a laptop? Thanks fellows.

    The powershot is a small box that attaches inline to the injectors to add fuel when you need it; it also has a plug to the MAP sensor, to intercept the signal and make the stock ECU think your boost level hasn't gone past the 7lb max in the stock ECU. Allows for up to 10lbs of boost, plus adding fuel. Just flashing lights and buttons, no display. $450-$500.

    The boost clamp is brand new yesterday from RIVA; it's just a boost fooling connector (same purpose as the powershot boost limit remover) but doesn't add any fuel to your stock ECU levels.

    IF you have a little more boost than the stock ECU will allow (let's say C-1 supercharger) AND you don't need to add fuel, the boost clamp would be a less expensive way to get full boost out of your supercharger. IF you NEED extra fuel, say with a C-3, or the B-1, or whatever supercharger impeller you choose, the Powershot is the better choice. Honestly, if you're at the $500 mark for the powershot, you might consider stepping up to a full reflash of your ECU for overall better performance. You get timing, fuel tables, Boost and Rev Limiters moved up, etc. $750 - $900.

    Depends on if you're keeping the ski, or selling it.

    Good luck!

    In the end you will be much happier with the reflash. (That is if you are trying to decide which to go with) The extra timing, higher rev limit and no boost limiter will really open your eyes. Trust me!

    The boost clamp is just a diode that tricks the computer into seeing a certain voltage a hair under the 5 volt refrence. So the ECU actually has no idea what boost your really making past a certain point. Say its a diode clamped for 4.55 or so volts. Anything past 4.55 volts it goes static meaning the ECU will only see a certain boost pressure and nothing more.

    Awesome post man. A+ seller. Would read again.

    And all these noobs need to read it 6 times so they get a good grasp on these concepts.

    Just one question for the reflash....will the OEM intercooler upgrade be sufficient or will the riva intercooler be needed and if not what will be the gain in performance over the oem intercooler upgrade with the riva intercooler.

    From a guy with a C3, R2 and a stock IC, you (we) should go new IC. Goodbye stocker in any form.
