The Holley EFI engineers have been busy cramming even more features into the popular HP & Dominator ECU's! With this most recent update, a ton of new crank and cam trigger patterns have been added allowing more even more end-user support. Getting Holley EFI onto your race vehicle has never been easier and our engineers will continue to push their ECU's to be some of the most capable on the market!

Aside from the new patterns, a few software changes were made including an update to the MSD Pro 600-8 Ignition Output. This will change the output signal duty cycle (mostly at cranking RPM) and although not required, is recommended that all Pro 600-8 users update to this latest build 160.
