This 12V type of signal is compatible with most new-style tachometers. However, some older
tachometers trigger off the high-voltage signal from the ignition coil (C-). These types of tachometers require
the use of a tachometer amplifier, since they are designed to trigger off of a 120 Volt signal.
5.7 Primary and Auxiliary Rev Limiter
Most RPM limiters feel like hitting a brick wall. The engine cuts off violently and recovers slowly. The
XDI's RPM limiter feels gentler and generates less sudden power changes in the engine, reducing stress. You
may even hit the first or second stage without realizing it, only noticing that the car stops accelerating and the
engine feels "soft". If this RPM is in your normal operating range, you probably want to raise the RPM limit.
The 3-Stage Soft Rev Limiter is a progressive rev limiter. When the specified RPM limit is reached, the
1
st
Stage is activated, and the XDI retards the timing to negative 12
o
. If the engine accelerates more than 50
RPM past the limit setting, the 2
nd
Stage is activated, and the coil current is cut in half (normally 9amps, it is cut
