What is the PR-4 EVO ECU
The Pro Tune PR-4 EVO is the evolution of the proven PR-4: an advanced engine management and data acquisition system (ECU) for internal combustion engines of up to 6 cylinders sequential or up to 12 cylinders in semi-sequential mode. It includes support for 2 customizable CAN buses for integration with external systems and proprietary networks.
Who it's for
Designed for tuners and race teams that need full sequential management up to 6 cylinders, dual boost and variable valve timing (VVT) control, Flex Fuel support and user channels for custom sensors. It is the ECU for advanced builds — high-performance 4- and 6-cylinder engines, turbo, supercharged and applications with special sensors.
Differences from the PR-Sport EVO
- Sequential injection up to 6 cylinders (PR-Sport: semi-sequential up to 6 cyl)
- 2 customizable CAN buses 100–1000 kbps (PR-Sport: SP only)
- Dual boost control and dual variable valve timing
- Native Flex Fuel support
- More inputs (10 vs. 6) and outputs (7 vs. 5)
- 48-pin Molex connector (vs. 36-pin JAE)
- Machined aluminum case (vs. polymer)
New firmware 300
The EVO version brings firmware 300 with faster sensor reading, improved Flex Fuel support, user channels for custom sensors and new control strategies.
Main features
- Built-in lambda/O2 sensor controller (Bosch LSU 4.2, LSU 4.9 and NTK)
- Dual boost control
- Dual variable valve timing control
- Built-in electronic throttle (drive-by-wire) control (dedicated ETC+ and ETC- outputs)
- Flex Fuel support
- Launch Control
- Traction control
- Power Shift — flat shift
- Anti Lag
- Asymmetric ignition
- Peak and Hold for low-impedance injectors
- Limp-home map (fallback for TP, MAF and MAP failures)
- Auxiliary injector bank
- Automatic lambda learning
- Password-protected map
- 32 MB continuous datalog (10 channels @ 10 Hz → 6 h / 10 channels @ 1 Hz → 60 h)

Frequently asked questions
How many cylinders does the PR-4 EVO support?
Up to 6 cylinders in full sequential mode, or up to 12 cylinders in semi-sequential mode.
Does it come with a pre-wired harness?
There are Without harness and With harness options. Bundles with the TDL 4.3 or TDL 7 EVO are also available. Select the variant on the page.
Does it support Flex Fuel?
Yes. Firmware 300 brings improved Flex Fuel support with user channels for custom sensors.
What's the difference between the PR-4 EVO and the PR-Sport EVO?
The PR-4 EVO offers full sequential injection, 2 customizable CAN buses, dual boost and VVT control, a 48-pin Molex connector and an aluminum case. The PR-Sport is more compact, semi-sequential and aimed at entry-level builds.
Does it include warranty and support?
Yes. Pro Tune technical support and a 1-year warranty (90-day statutory warranty + 9-month contractual warranty), as set out in the Warranty Terms.
