Product Information
Specification

Pro Tune PR-4 is an advanced electronic engine management system and data acquisition ECU. It has integrated tools for control of injection and ignition systems up to 4 cylinders in sequential mode, or up to 8 cylinders in semi sequential mode, compatible with most 2 and 4 stroke engines. Available alone, with plug & pins , or with Pro Tune PR-4 Wiring Harness, please select your requirements in the options above when placing your order.

 

The ECU has standard functions and additional (fully enabled) functions to control modern systems such as variable camshaft control, drive-by-wire throttles and boost control. In addition, it features integrated wideband lambda control, CAN network, and USB communication interface & supports Peak and Hold injectors. Connect-Box expanders adds up to 8 programmable user functions, allowing great versatility and providing the ideal solution for professionals and enthusiasts alike.
