Holley Releases EFI V5 Software Upgrade

Holley/MSD is pleased to announce the Holley EFI – V5 a new software upgrade from Holley EFI. One of the coolest things this software update feature is Active Speed Management, which allows racers to personally customize up to three sets of injectors. If you haven’t upgraded to EFI yet or just want to know more about it check out this article.

V5’s ASM functionality is based on the time from launch versus engine speed and driveshaft speed (one or both can be used). You can enter numerous different curves to retard ignition timing and even enable rev-limiting based on the departure of wheel speed or engine speed from the base curve. The addition of ASM to a Holley EFI system requires the purchase of PN 555-100. Each purchase allows activation of the Active Speed Management in a single ECU. To purchase ASM, click here and follow the simple step-by-step instructions.

The software’s new Customizable Injector Configuration gives you virtually limitless options to sequence and tune the fuel contribution from each set of injectors when you use two or three injector sets. Each set can be run sequentially, and each set can be individually chosen to perform individual cylinder, cranking, and startup prime fueling. It’s compatible with almost any multi-injector set application and ideal for Roots supercharged and dual-fuel applications. V5’s existing Electronic Transmission Control feature is bolstered by the addition of several new transmissions to the drop-down menu, including Ford’s popular 4R70W and GM’s 4L65E. Several new injectors have also been added to the injector dropdown menu to help you quickly dial injector off-times and minimum injector opening time. New Data-monitor windows are now simple to create – just click the “X” on the top-left corner to clear it. And all types of ignition outputs, including points and EST now can have individual cylinder timing control.
