The RX does not go into closed loop in the driveway. Period.

The only way it'll go into closed loop is if you remvoe the TPS connector and put it in gear and rev over approx 1700 rpm. See book.

Stk timing is 5L and 20T at idle last time I looked. Its that below approx 1100 rpm. Then it advances all by it's lonesome.

Series four idle good at approcx 13 afr give or take a touch. That's reading the AFR with NO airpump/acv dumping air into the exhaust ports which are prior to the 02 sensor. If your reading afrs with a active airpump/acv then your not reading the REAL engine afr.
