Important Notes Summary:
Rotor phase must be checked when using large retard values in the Driveshaft Error Table.
The Timer Enable sequence will be reactivated, every time the throttle is closed and then opened
again (if you get off and then on the throttle again during a pass). Until the “Blend” feature is active.
The three “Boost Spark Retard Tables “are not functional with the SR
2
system.
Make sure all of the magnets in the magnetic ring are all installed in the SAME direction.
If the TOSS_rpm trace is erratic switch the wires!
To ensure that the 1
st
Gear Retard system becomes active when the trans-brake or clutch are released,
make sure the Minimum RPM & TPS values are exceeded while on the 2/3-Step when the trans-
brake is on or the clutch is depressed.
The SR
2
1
st
Gear Retard system allows only one Timer Enable activation. To eliminate the
potential of activating the Timer Enable wire during the pre-stage burnout, put the Timer enable wire
on its own On/Off switch. After the burnout, turn on the switch.
The timer enable wire must have 12V applied to it the moment the trans-brake button or clutch is
released. See relay wiring diagrams earlier in this manual.
The SR
2
system requires that the timer enable and DAE trigger wires be on separate On/Off switches.
Make sure the “Minimum RPM” in the Boost Parameters section is set 500 RPM below your 2 Step
RPM Hi (3-Step) RPM setting under Configuration/Operating Configuration from the main
BigComm toolbar
Next, immediately save the calibration (the file
ending in .big) from the GEN3 ECU into the
new SR2_BigComm folder!!
