REV2 Controller- The most advanced and industry first FLEXRAY AND DIRECTPWM motorsport ECU featuring an IP66 waterproof enclosure and Mil-Spec motorsport- grade wiring harness.
 
Once installed in a vehicle, REV2 Controller integrates with the DME using the incredibly fast and robust FlexRay ™ protocol. In addition, bootmod3 CustomROM V2 goes a step further and implements a highly innovative PWM control strategy, DirectPWM.
 
What is FlexRay™?
FlexRay™ is a high-speed communication protocol used in vehicles and aircraft. It's designed to be reliable, fault-tolerant, and efficient. Its used in safety-critical applications, advanced driver assistance systems, power train, body control modules, battery management systems, and more. Over the past decade, vehicle manufacturers have transitioned away from CANBUS on modern vehicles for many in-vehicle control systems and REV2 Controller has followed that trend.
 
What is DirectPWM?
bootmod3 CustomROM V2 software update implements DirectPWM to re-purpose an existing DME pin output and uses it to send a PWM signal directly through the OEM factory vehicle harness to a REV2 input. REV2 in turn replicates that PWM signal to one of its outputs. With no communication protocol overhead involved, DirectPWM provides for the absolute fastest, most direct control of a REV2 connected output.
Which outputs can use DirectPWM, and how is this configured?
Sequential Port Injection and Boost Control Solenoid (MAC valve) are configurable with DirectPWM trigger control. Tuners and end users simply toggle it on the bootmod3 Map Configuration screen and store it on the DME. Integration is seamless and no configuration/updates are required to the REV2 Controller.
 
Once my REV2 is installed in the vehicle, do I need to connect it for any tuning like with some standalone ECUs?
No. You simply install the REV2 and forget about it :) All your tuning is still done on the DME using the bootmod3 Map Editor.
 
How do I update firmware on the REV2?
Although firmware updates are a very rare occurrence since REV2 contains no state or tuning data, for the odd occasion we may have a firmware bug, REV2 Controller integrates WiFi. Any firmware updates would be done simply through the bootmod3 app like with our bootmod3 WiFi Adapter.
