The touchy throttle and abysmal lag at low RPMs of the 2 have been bothering me for a while. I've noticed that this isn't an issue when the clutch is depressed; throttle response is greatly improved when the clutch is disengaged, and the throttle is much more linear, instead of the super aggressive response for the first half of pedal travel, and almost nothing towards the last 2/3 of travel that the car has stock. I know this can be remedied with a tune, but I definitely don't have $500 to spend on one at the moment, so I thought up another method.
In order to implement this, simply disconnect the clutch actuation sensor (blue sensor in above photo). There are two sensors on the clutch pedal; one to determine if the clutch is depressed fully for starting the vehicle, and another for determining if the clutch is depressed at all for the cruise control on the touring models, and also for switching the throttle mapping on both models (I assume so that people don't stall the car every single time they take off due to the immense lag). The sensor you want to disconnect is the one that is closer to the driver. It is a simple clip, just use your fingernail or a small screwdriver to press in the locking pin and disconnect the sensor connector. This effectively fools the ECU into thinking that the clutch is depressed all the time and it stays in the more responsive throttle map.
Throttle response is greatly improved in the low RPM ranges, and the throttle is now linear. It will be fairly noticeable when you drive around the first time after disconnecting the sensor. The only reservation I have with this is I'm not certain if there is a neutral ignition map that the car now uses instead of the normal ignition map it should be using. I haven't noted any CELs as a result, but I have yet to test it long term. Take of it what you will; its a quick and easy reversible mod.
