Constructing a sinewave generator for idle leanburn
With the 48 state VX ecu leanburn kicks out at about 1 or 2 mph at idle rpm. Are there any electronic folks in here willing to disclose plans for a sine wave generator to mimic the speed sensor at the flip of a switch? I'm not sure of the voltage or frequency yet. Has anyone attempted this?
It would be nice to flip a SPDT 2 position switch at stop lights or coasting while idling activating a sine wave generator which mimics the VSS at X mph.
I'll take care of the other condition which must be met to activate leanburn - the TPS and more airflow - with a pneumatic cylinder and air solenoid operated by vacuum pushing the throttle just off its idle position.
Wonder if this would trick the ecu allowing for leanburn in 1st gear? I wonder how much gear correction takes place in the fuel/ignition maps - adverse effects of a VSS simulator being left on?
