I've been working on an idle ECU update and just wondering what the difference there is between an auto or 5 speed.
I know with the 5 speed some owners may keep the engine engaged right down to idle RPM. I'm not one of those, I press the clutch when I'm ready to change gears to downshift. Even press the clutch coming to a stop way before nearing idle RPM.
So with an auto, I would think the dropping RPM would be much slower because the car movement is still helping the engine RPM to drop slower. Is that a correct assumption? I was wondering if I should have a user switch that changes some software timing for an auto.
My new software uses the idle switch input signal so running without the idle switch is not an option. That signal lets my software know when the user has let off the throttle.
Still don't know why an auto with stage 2 would cause problems other than it could fake out the lambda with high duration cams.
