9.4 Post Start Enrichment
On some motors, in particular rotaries there is a problem with vapour-lock (fuel which due to
heating of the fuel rail has vaporised). The additional fuel at start up allows the vapour in the
fuel rail to be purged through the injectors and also allow enough fuel to be injected into the
motor to allow stable operation. Post start can also be used to give extra enrichment when the
engine is cold to assist drivability.
The Post Start Map is accessed via the Maps menu. It covers a programmable period of 1- 120
seconds. The time starts after the first input trigger is received.
Post Start has two programmable settings accessible in the fuel set-up page:
Post Start Time Limit
Post Start Temp. Limit
Post Start Temp Limit has a secondary field that defines whether post start operates above or
below the programmed temperature. For more information on these parameters refer to 4.2.2
Fuel Set-up Page, p36.
