next up, fixing my throttle. recall last week, my TPS was showing 83% open at full throttle. now look in the baseline plot above & see how my AFR is 14.7 up to 4500RPM.
the car uses throttle position & RPM to determine whether to run in open loop (fuel maps) or closed loop (O2 sensors / 14.7AFR / 'Econo Mode'). in the plot above, i have the throttle pegged, but i'm still running 14.7. that's WAY lean for WOT & possibly dangerous to the motor. i have been driving it on the track like that!
i popped the engine lid to have a look. sure enough, lots of slack in the cable. i repaired it with a cable stop from ace hardware. now at WOT, the TPS signals 100%. what does that bring us?
Hybrid Mode
