Message After being TT for a couple of years I finally got around to putting VTC back on the car and it was definitely worth it. My question has to do about the activation points.

I understand the min/max temp, min speed, RPM cut and TP settings. The RPM "on" setting is the problem. On the TT the on setting (6100) is set above the cut (5900) setting which makes the TT turn on the VTC by the TP value only. On NA cars the on is set at 1800 and cut at 5900. The TP is also higher on NA at 40 iirc and 24 of TT. My problem is that when I set the on to 1800 the VTC does not activate above 1800. It appears to still be activating according to TP.

Is the "on" setting not really an on setting but instead a lower RPM limit meaning that on NA the RPM has to be above 1800 and the TP above 40 to activate VTC?
