GCU7 Manual

Starting PID:
PID parameters for first phase of the car starting off. This is until the car starts to move.
Once the car is moving (vehicle speed > 0), PID2 is used. PID controls always checks against the current
rpm and the rpm calculated for current gear. First box is parameter
P
,
second box is
I
,
third box is
D
.
General rules:
- start with 0.1, 0.1, 0 (P,I,D) for both PID and PID2
- if you add throttle and car is slow on starting to move and rpm gets too high,
P
is too low and you need
to increase it. Do it in 0.1 steps. When it’s too fast, lower the
P
in 0.1 steps and increase
I
by 0.05.
- once the car starts to move
P
,
I
and
D
are no longer used so you need to change
P2
,
I2
and
D2
.
- For
P2
,
I2
and
D2
similar logic applies. If rpm is rising too fast and car is not accelerating enough (clutch
slip increases), increase
P2
and/or
I2
. Use 0.05 increases/decreases.
