My 2012 Toyota FJ Cruiser has a 6 speed manual. The vehicles computer adjusts the RPM's based upon the mph. For example, if I am going downhill (45 mph) and put the tranny in neutral and foot off the gas, the computer idles up to 1,500 rpm. The faster the mph, the faster the rpm. Typical manual trannys allow the vehicle to idle as normal at 6-700 rpm.

Has anybody on this forum been able to over-ride their car computer to adjust the idle as it should be?
