Additional FeaturesPower Steering pump (used pump from an MR2) provides adequate
pressure for steering rack. Vehicle steers very easily.

Iota 12VDC supply and heater are powered from 120VAC when vehicle is
plugged in to external power.

Performance much improved since installing the Synkromotive
controller. (Previously had a Curtis 1231C.) Also really like the
capability to set many different operating parameters (max currents,
min battery voltage, etc).
Started conversion in September 2008. Got it inspected and tagged
July 2010. Been driving it to work and back home (approx average 8
miles per day) most work days since early August 2010.

Can really tell the difference in acceleration and efficiency when
the truck went from 1500 pounds of lead-acid to 200 pounds of
Lithium. (January 2018)

Fun to drive and nice to have reduced my gasoline consumption!

*Credit for the nickname goes to a friend - though the vehicle is not
hybrid, I still got a chuckle out of his nickname for it!
