We could talk about what the HP ECU can do for quite a while, but it's easier to visualize that it's a Dominator without the extra I/O, only single wideband support, and no ability to support drive-by-wire or electronic transmissions. But we sell more HPs than any other system, and racers love the built-in automatic data logging.

• Multiple wideband O2 support.

• Any fuel type: Gas, E85, or Methanol.

• Fully laptop tunable.

• ​

Cons:

• It's not a Dominator – but it's close.
