You just choose it in the software...your harness has to be correct for 24x or 58x but the same holley ecu can do either one. Feel free to call us on Monday or email us and we can spec you out a holley system.

Thanks every body for helping! I’m in vacation in Los Angeles CA for 2 day, then travel to Las Vegas NV for 4 day, then travel to Phoenix AZ for 3 day all by car. If any one have or see a great deal on a Holley HP or Domminator new or use. If you have something in those area PM me and I will contact you for pick up.
