Hi all,

Just recently had my GTD tuned to stage 1 by Superchips. I have also been using a DTUK pedalbox for better throttle response.

The lad installing my tune told me not to install the pedalbox back on, as apparently that can confused the ECU and reset the map back to the stock setting. I'm not saying I don't believe it, but I just wanted to reconfirm that is true? As I can't find anything on any forum regarding that, only that people have been using a pedalbox with a stage 1 tune.

Thank you all for any help.

I don't know why the ECU would be confused. All the pedal boxes do is send more pedal input than you have applied. For example, you have pressed the pedal 25% of the way, the pedal box sends a signal to the ECU for 50%. But 100% pedal is still is 100%, you just get to 100% quicker with the pedal box.

Some (many) ECU tunes increase throttle response anyway so you may no longer need the pedal box. I would drive the car without the pedal box (or set the pedal box to lowest/off setting) and see how you like it. But pedal box will always give you more response than a tune can, because the pedal box is giving you "more pedal" than you are actually pressing.

This was my thought process behind it. I'm not really sure what there if for it to get confused by.
