FuelTech didn’t stop at the programmable and multi-channel upgrades; it also includes diagnostic capabilities in the system to prevent problems and catastrophic failures. The Peak and Hold PRO can perform a quick pulse of the injectors at the push of the start button to ensure all injectors are connected and operating properly. If it detects one or more injectors not opening/closing correctly, it will activate a warning signal on the LED screen of certain PowerFT ECUs (FT450, FT550, and FT600) and not allow the engine to start up.
Another fail-safe feature is the Peak and Hold PRO’s ability to shut off all the fuel injectors while the engine is running if one or more injectors fail due to a broken clip or another reason. Engines that run 16 injectors and two Peak and Hold PRO units also benefit from the fail-safe shutoff. The two units communicate through a wired connection and both boxes will shutoff if one injector stops working in either system.
The Peak and Hold PRO operates on CAN communication, allowing all of the information to record on the FuelTech data log and be viewed in FTManager. The FuelTech engineers also upgraded the connector to a user-friendly version that doesn’t require special tools for pinning. It is the same connector on the Alcohol O2 conditioner and FuelTech offers jumper/adapter harnesses for old Peak and Hold box users to easily swap to the new one with minimal effort. Like the FTSPARK and FTSPARK II, the new version is built in the same enclosure as the previous generation to allow customers to use the same mounting solutions in their racecars.
