Falcon Kit Car
Falcon uses suspension and drivetrain components from a
Ford Sierra donor car. A sensible approach, this means spares
are easily and cheaply obtained. This example of the Falcon
was fitted with a Ford Pinto 2.0 engine.
induction side, twin Weber carburettors help to give the
Pinto better performance at the top end of the rev-range,
and the owner believes an uprated cam has also been fitted.
As is usually the case, these improvements at the top-end
meant tractability at low speed was adversely affected.
As usual with a twin Weber setup, there was nowhere to connect
a vacuum advance pipe to on the inlet manifold and therefore
the distributor relied on centrifugal advance only. In an
attempt to claw back the driveability of the car whilst
also maintaining or improving the high-revving abilities,
the owner decided to fit a Canems Ignition ECU.
pulley was fitted with a laser cut trigger wheel, secured
with a spacer in between the pulley retaining nut and the
pulley itself. Sticking with the donor-car principle of
the JBA, the owner sourced the crank sensor, coil pack and
plug leads from a Ford Ka. The coil pack was fitted in the
same location as the original single coil, and therefore
the leads emerge at the original location. Although original
appearance was not really an issue on this car, it's nice
to maintain a factory-fitted standard of appearance.
initial testing, the distributor was left in place. This
is very important on the Pinto, as the distributor drive
shaft also rotates the oil pump. Now that the car is fully
tested, the owner is hoping to turn down an old distributor
body in a lathe to reclaim some space in the otherwise cramped
the ECU 3D map capability, a throttle position sensor was
fitted from a Rover Metro. A simple bracket was fabricated
to support the TPS, so that it would rotate with the butterfly
spindle on the Weber carbs.
engine is one of the most common engines for our ECU conversions
and therefore we were confident that the base-map supplied
in our ECU would form a great starting point from which
to commence fine tuning.
the test drive, the spark plugs were opened out to a gap
of 0.035". Static timing was also double-checked with
a strobe light. The ECU was supplied with a static timing
figure for the missing tooth on the trigger wheel, and in
this case the strobe showed that the missing tooth was a
few degrees out on where it should have been. The static
timing was therefore adjusted within the tuning software,
so that this error would be taken into consideration by
the ECU when firing the plugs.
first drive confirmed that the original distributor / single
coil system was really letting the car down. Idle quality,
smoothness through the rev-range and particularly pulling
from low speed and on the overrun were all improved.
