Progressive TBI Enable/Disable:
This should be selected if using a TBI throttle body with progressive throttle linkage. All 4 BBL
TERMINATOR™ TBI systems do NOT have progressive linkage, so this should not be checked. This will NOT be shown if you have
selected a MPFI application.
TBI Secondary Blend:
If using a TBI with progressive linkage, this value is used to start the ramp-in of the secondary fuel injectors as the
rear throttle plates open. Enter the TPS when the rear throttle plates start to open. This is typically 36% for a Holley throttle body unit.
The “Check for Progressive Throttle Linkage” must be checked for this box to be enabled. This will NOT be shown if you have selected a
MPFI application
NOTE:
Holley
MPFI and TERMINATOR™ injector size/flow is calculated at 43 PSI.

It will not shut fuel off. Enter a value for which you’d like the rev limiter to start.
