 Re: How to properly disable Exhaust Valve 2011 L1 GSX R750 |
Great, thanks! I actually have a full exhaust on my bike, so when I put that on, I curled up the wire from the set valve motor, and spooled it up tucked under the larger plastic cover on the left side, just in case I ever do reinstall my oem system. I left everything else plugged in. If I ever was in limp mode, I'm sure the Fi light would be on anyway. I was curious though about the maps for sure, if you have the set valve disabled in the woolich software, shouldn't you have the set valve maps set to 100 across the cell range? 
Oh well, if only we had affordable dyno's at our disposal at home to test these silly thoughts out lol. |

| I have an L2 GSXR750, California edition. Since you have the Woolich package, all you need to do to disable the SET valve is to check the "Disable Exhaust Valve" in the Advanced settings and flash the ECU. This will disable the servo that activates the valve (tested). Alternatively, you can remove the cables at the valve and the return spring will keep the valve open but that really isn't necessary unless you are removing the server and the cables all together. You can wire the valve in the open position if you wish to insure that the valve never closes.
Another way I've seen it done is to go to the Exhaust Valve map (under "Other Maps") and fill all the cells to 100% while leaving the "Disable Exhaust Valve" unchecked.
As far a other map changes, I have not made any and left it to Auto Tune to make the necessary AFR adjustments. Interesting point about the affect with STP but I believe that STP doesn't come into play until higher RPMs where the Exhaust valve will be in a more "open" state. |

| I've read around that if you wrongly disable the Exhaust Valve, you can trip your bike into limp mode.
I've got the motor plugged in still, but have pulled the ECU plug to disable the valve, what exactly does disabling this in the woolich software do?
Is there anything you need to do with the STP maps after disabling the valve? (or any maps for that matter) |
