SNOW PERFORMANCE Boost Cooler Stage 3 EFI Controller Upgrade

Boost Cooler Stage 3 EFI control unit upgrade

The multi-award-winning Boost Cooler Stage 3 EFI control unit from SNOW Performance regulates the water or water-alcohol injection quantity progressively in relation to the boost pressure and the fuel injection quantity.

The desired start and full injection times are simply entered on the enclosed LCD screen. The controller then creates a 2D injection curve for the optimum injection quantity in all load ranges. By using boost pressure and fuel injection valve timing, the Stage 3 control unit enables very precise water-methanol injection quantity regulation.

In addition to the primary injection nozzle, another nozzle, independent of the primary nozzle, is optionally controlled by the control unit. - This ensures optimal use of cooling and performance in all load ranges of the engine.

The progressive injection of water or water/methanol based on the created 2D mapping is very precise and has a positive effect on cooling and engine performance over the largest possible engine load range.

Recommended for all naturally aspirated engines as well as turbocharged and supercharged engines with intake manifold injection.
