    ECU Reflash and Fuel Economy- Any improvement??

    I am starting on some mods on my 2011 SHO. I know what I will do with it as I want a ride all day/every day recreational ski with speed up to the mid 70's.

    A level 2 ecu reflash (R&D/V Tech) to run a low boost wheel is a must do.

    My real question for all you guys that have done the ecu reflash is "what happened to your fuel economy"???

    Given the increased speeds and performance, have you guys noticed any improvement or otherwise in fuel consumption for normal riding.

    It has been said that a 30% improvement in fuel economy with a Motec is possible. I am trying to find out if a reflash, as opposed to a new programmable ecu, provides better fuel economy for normal riding.

    Cheers

    From what I read, a reflash on a low boost ski helps improve fuel economy. The stock ski runs pretty rich from the factory. Always a good idea to keep an eye on AFRs as well

    I ran through a tank of gas with a guy who has a R2 reflash and supporting mods with the stock wheel on his FZR. My bone stock SHO was on the buzzer before his 78 mph ski was.

    Go into the store and search for ecu reflash. R&D and VTech reflash the OEM ECU. They have a menu of benefits and changes under each level of reflash. The bit that is missing is what happens to the fuel economy!! That's what I am trying to find out from the experts here who have had the reflash done.

    Absolutely! Higher rev limiter and raised boost limit would grealty increase acceleration. I would recommend supporting mods for full benefit.... air intake, exhaust, manifold upgrade.

    I have a V-Tech Re-Flash on my VXR and I can safely say it is at least 20% better on fuel economy, Julio...

    My fuel usage sure went down when I went to the R3. Even with the C1 its better than stock.
