Holley hp or dominator on turbo nova
Hardware
The following differentiate these two ECU’s:
- Wide Band Oxygen Sensor Inputs
o HP – One input
o Dominator – Two inputs
- The Dominator can control certain Drive by Wire throttle body applications, the HP does not.
- The Dominator can control certain Electronic Transmissions (GM 4L60/5E and 4L80/5E), the HP does not.
- Inputs and Outputs
o HP
2 high side (+12v) PWM or switched outputs
2 low side (ground) PWM or switched outputs
4 Multi-inputs
o Dominator
20 high side (+12v) PWM or switched outputs
16 how side (ground) PWM or switched outputs
6 speed inputs (magnetic or hall effect)
30 0-5v sensor inputs
13 Multi-inputs
- The Dominator has a “configuration input selection” pin that allows up to 4 calibrations to be selected with a key switch
I have the Dominator as I have a G meter, shock sensors, multiple pressure sensors, boost controler, and drive shaft speed sensor which all are run through the Dominator and data logged by it as well.
Really depends on what you are going to do with the car and how much you are going to ask the ECU to do as to which system is right for you. Both use the same software and are great systems.
