SMT8_4 Technical Manual - Injection Map #1

SMT8_4 TECHNICAL MANUAL

Support for your SMT8 V4 Unit.

INJECTION MAP #1

 

 

PURPOSE

The INJECTION #1 (F1) screen allows the control of ONE injector placed in the manifold.

The injector must be wired to the SP1 output and assigned to it in the SET-POINT procedure.

EXTRA INJECTOR ACCELERATION ENRICHMENT

SMT8V4 Piggy-Back Unit - F11 - Acceleration

SMT8V4 Piggy-Back Unit - ShiftF1 - Parameters

The Acc enrichment map adds extra fuel when the extra injector is in operation.

Acc Detection: value entered is in Bar (based on the AMP Calibration table) so that when the value is exceeded the map will be enabled.

Acc Deplete: (is a counts entry where 100 means 1ms), will deplete the extra fuel over the entered time after acc detection.

 

 

ASSOCIATED PINS

 

Throttle deflection:   Pin 13 of the 16-pin connector
Manifold pressure:   Pin 3 of the 16-pin connector
Injector outputs: (SP1) Pin 7 of the 10-pin connector
POWER GROUND:   Pin 1 of the 10-pin connector

MAIN (RPM/THROTTLE) MAP

 

Enter a number in the range from 0 to 999 on the main map. A zero entry disables the injector output. An entry of 100 is the equivalent of 1.00 MS (milliseconds) injection.

 

 

AMP SIGNAL TABLE (OPTIONAL)

 

A multiplication factor in the range from 0.01 to 9.99 can be used. An entry of 1.00 will do no multiplication to the value in the main map. The MAP deflection comes from the AMP (IN) pin 3 of the 12-pin connector.

 

 

ENGINE TEMPERATURE MAP (OPTIONAL)

 

The entry in this map is ADDED to the main fuel map entry. Entries range from 0 to 999. 100 counts equate to 1.00 MS.

 

 

AIR TEMPERATURE MAP (OPTIONAL)

 

The entry in this map in the range from 0 to 999 is added to the other map values. An entry of 100 results in 1.00MS added fuel.
