These highly refined maps lower operating temperatures, eliminate exhaust popping between shifts and deceleration, and improve throttle response and performance. While it is true that a base map is required, we have an ever-growing library of base maps including many engine and exhaust combinations. ThunderMax’s processor can keep up with the ever- changing demands, rewarding you with a powerful engine that runs very smoothly and efficiently.

ThunderMax covered the bases with a system that operates using 1,984 points! Simply put, regardless of throttle position and engine RPM, there is a block on the look-up table to address the engine’s needs in that situation. For this type of system to work properly, it requires many more “blocks” on the look-up table. The Harley’s® uneven firing pulses and common plenum manifold can confuse the MAP sensor, and cause it to supply fuel and spark from the wrong block, resulting in poor performance. The ThunderMax is an Alpha-N based system, meaning it relies on rpm and throttle position only it does not use data from the MAP sensor. These points of adjustment are ALL addressed during the creation of base maps and are the key to unlocking a bikes potential.Īll processors use a look-up table to deliver the specified amount of fuel and spark timing for a given rpm/load situation. The system utilizes a very fast, powerful processor which allows a higher resolution of tuning points than any of the other popular add-ons, including the factory’s Race Tuner® software. The Th underMax EFI eliminates the requirement of any add-on tuning products and was developed with complete versatility in mind.
