ACCEL/DFI

curve is pre-programmed into the ECM from ACCEL DFI. It
has initial timing of 20 degrees BTDC and a total timing of
34 degrees BTDC in by 3000 RPM. The timing curves, as
well as all other tables in the ECM, can be adjusted to better
suit your engines requirements using ACCEL DFI’s
calibration software “CALMAP”.

NOTE: If an aftermarket ignition enhancer box is used (i.e.
ACCEL 300+, MALLORY HyFire), the TFI distributor can be
wired as described by the manufacturer of the enhancer
box. However, if you are controlling timing with a magnetic
pick-up distributor or a crank trigger, refer to the
illustration below.
