mid-grade and higher-fuel for optimal performance gains.
RapTorq High Performance ECM
Our unique proprietary & copyrighted Predator RapTorq
ECM was engineered over a 22 month span with specific testing and development
by our in-house Predator Motorsports engineering team.
During the development phases of our RapTorq ECM, our
engineering team included a full evaluation of all available ECM programs by
our competitors. While it remains standard practice to only modify the factory
GM fuel-delivery curve. Our RapTorq ECM features a completely re-engineered
“fuel-delivery curve &start-of-injection timing curve”. This design is
engineered to optimize the H2’s combustion chamber providing peak efficiency
and rapid power gains across the engines entire power band.
Our RapTorq ECM programming provides rapid throttle response
from light-throttle to full heavy-throttle performance power. In conjunction
with power gains, Fuel Economy is also improved on an average of 10-20%
throughout all operational conditions. The primary goal was to create superior
drivability with a maximum power curve within the OEM GM exhaust-gas
