Flatattack racing efi

[Bored&Stroked]

FAST was a super popular EFI ECU for many applications - one of the first designed to support both DIYers as well as Professional Tuners. This was prior to the extensive efforts that Holley put into their whole fuel-injection systems, ECUs and other components.

I give Holley a lot of kudus for how they've structured their product lines and the fact that the same EFI tuning software is used across almost all of their products - good stuff!
