Abstract: The current invention includes throttle body devices with an air intake, a throttle plate in the air intake including a throttle plate shaft, wherein the throttle plate shaft horizontally traverses the throttle body, a throttle position sensor (“TPS”) attached to an end of the throttle plate shaft, and a rotational adjustment ring disposed between the throttle position sensor and the throttle body. The throttle position sensor is coupled to the rotational adjustment ring, and the rotational adjustment ring is rotatably adjustable to allow adjustment of the voltages sent from the TPS to an engine control until (“ECU”) at given positions.

Abstract: A battery includes an on-board microprocessor-controlled MOSFET-switched cell monitoring and protection system which provides over-charge protection, low-voltage protection, thermal-runaway protection and cell balancing. The output voltage of the battery is fully regulated and user adjustable. Internal switching provides for switching the battery on or off from a control interface on the battery housing or from a remotely located switch. The battery preferably incorporates lithium iron phosphate (LiFePO4) power cells, although the monitoring and protection circuitry is also applicable to lithium ion and other cell chemistries. The battery includes a charging input connection separate from the voltage output connection which allows for charging the battery at a voltage considerably higher than the output voltage.
