7.8 Advanced Engine 7 ADDITIONAL ITEMS: BEYOND BASIC FUEL AND IGNITION CONTROL
7.8.17 Nitrous - RPM based progressive
These curves work in the same manner as the time based progressive curves, but use RPM for the X axis
instead of time.
7.8.18 Nitrous - VSS based progressive
These curves work in the same way as the above two curves, but use speed instead of RPM or time.
7.8.19 Water injection
Water/meth injection is primarily used in boosted applications for charge cooling to reduce the tendency to knock,
often allowing boost to be increased. Due to limited capacity of water/meth reservoirs this will mainly be of use
for short duration sprints and less of use for endurance racing. (Make sure the reservoir does not run empty! The
MS3Pro can use a level switch to check this.)
The MS3Pro system can control a pump via a relay when conditions are met and map the duty cycle of a water
valve on a 3D map of duty vs MAP vs RPM. The valve may either be fast acting (runs at injector speed) or a slow
speed similar to a boost solenoid.
