Start-stop & comfort
Small changes, daily difference
Start-stop is the one owners ask about most. The button turns it off for one journey; the car forgets every time you restart it. Written into the calibration, off means off — permanently, and without a dongle hanging out of your OBD port.
Several manufacturers also ship hidden instrument functions — oil temperature, boost, power and torque displays — that are simply switched off in the market calibration. Where your car has them, we can turn them on.
And hot-start trouble, where a warm engine cranks and cranks before it fires, is often a known calibration behaviour rather than a failing starter or battery. It is worth checking before anyone sells you parts.

Good to know
Questions we hear every week.
Does disabling start-stop affect the warranty?
Any calibration change can be visible to a dealer. Your original file is saved, so the car can be returned to standard before a warranty visit if you prefer.
Will a warning light appear?
Not when it is done properly in the calibration. That is the difference between this and a cheap OBD dongle.
Can you enable sport displays on any car?
Only where the manufacturer built them in and switched them off. Tell us the model and we will confirm before you book.
