Self revving while rolling

[BCX]

Good to hear!

The injector decel cut is where you'll hopefully see some fuel saving. If you're off the throttle, rolling down a hill and engine speed is over ~1100 rpm (varies), the injectors will turn off completely.

This behaviour wont happen without all the conditions being met - one of which is the idle switch!

I found (as has Steve from TME) that TPS set to 13.3% is the sweet spot.

Need to ensure the throttle cable has a bit of slack in it to ensure it rests of the stop screw (and if TPS correctly adjusted, the idle switch is working)

The idle rest switch is within the TPS (or APS if you got ASC)
For TPS (non ASC) measure continuity between pin 1 - earth (black wire) and pin 2 - idle switch (yellow/red wire).
For APS (with ASC) measure continuity between pin 4 - earth (black wire) and pin 3 - idle switch (yellow/red wire).

Continuity only when throttle/pedal is at rest.

I upgraded my throttle body to the larger version. My TPS is reading 11.76%. can I adjust this through Evoscan when the car ignition is on engine not running?

Should I also put in the .65mm feeler before adjusting the TPS?
