Failed Emission Test update

[rover3l]

Replaced my split under plenum vacuum hose and now the emissions are normal. With a bunch of air being sucked apparently it would cause the fuel system to dump excess fuel into the engine. It also accelerates a lot better now from rest

After repairing this problem does the Q need to reprogram its on board electronics by learning the new driving pattern?

[elwesso]

Wow I was skeptical of that...... Very good...

The Q will relearn everything..... If youd like you cna unplug the battery overnight... It helps probably none, but the placebo affect kicks in for me.....

How long does it take to re-learn?

I can't believe the difference it has made so far. It ideals really smooth and pull steadily of line without feeling it is holding back. Once up to 40 mph if I floor it it really flys

[911/Q45]

It's already learned what it needs, no reason to reset.

90-95Q relearn ecu in 10 minutes, tcu an hour of typical shifting.1996 a little longer of each but under 55 miles.
