Thread: Terminator MPFI LS System Questions

    Default Terminator MPFI LS System Questions

    So I've been searching around and found some answers, but from posts two years old, so I'm hoping someone can freshen the data pool up a bit.
    1. Is the MPFI Terminator system HP limited by anything? I know the TB style is limited by the injector flow, but with MPFI you have more flexibility. Is there something else that limits its performance? Injector driver duty cycle, software? (Supposedly same as Dominator from other posts read.) Or something else?
    2. There was a post in 2014 asking if the Terminator system will be able to support WBO2 sensors and the response was that they were hoping to introduce it soon. Are you able to run two WBO2 sensor now?
    3. I saw another post on this forum that states the Terminator ECU with transmission control is the Dominator ECU. Is this true? If it is actually a Dominator ECU have they limited its features? Have they not included some of the plugins? From my reading, the Dominator has more Input/Output flexibility and can run dual WBO2 sensors, etc.

    Thanks to anyone who may be able to shed some light on these questions. Waiting on my MPFI LS Terminator Kit to ship. I have these questions, but still think it's the best option for me and hence the purchase.

    No, the fuel injector size (& fuel pump) determines horsepower capability.

    2. There was a post in 2014 asking if the Terminator system will be able to support two WBO2 sensors and the response was that they were hoping to introduce it soon. Are you able to run two WBO2 sensor now?
    No, only the Dominator ECU has dual WBO2 sensor capability.

    3. I saw another post on this forum that states the Terminator ECU with transmission control is the Dominator ECU. Is this true?
    Yes.

    If it is actually a Dominator ECU have they limited its features? Have they not included some of the plugins?
    No, it's the same Dominator ECU with all its capability.

    From my reading, the Dominator has more Input/Output flexibility and can run dual WBO2 sensors, etc.
    Yes: http://documents.holley.com/techlibr...useanddiff.pdf (Holley HP & Dominator ECU Differences)

    Thanks for answering that so quick. Just to clarify a few things. Only the Dominator ECU has dual wideband capability. Cool. The Terminator with transmission control ECU is a Dominator ECU in all it's wonderfulness. Neat. So if I've ordered the MPFI LS Terminator Kit with transmission control, then I'll be able to run dual widebands because I'm in fact receiving the Dominator ECU?

    Yes to everything you've stated. Nothing has changed in terms of HP vs Dominator ECU capability. Read the LINK in post #2.
