# EEC Tuner for window 95/98/2000 v2.08 release notes

Fix for EEC-V Bank 8 modifications. Same tuner.dll used with the GUI EEC Tuner software.

New format for the A9L-series datalogging. Use the a9l_v208datalog.eec payload in your modification file to log data.

# v2.04 Release notes

#### Tag additions

> OL_TP_VOLTAGE - This is the voltage delta from closed throttle that unconditionally causes fuel to go Open Loop mode (HEGO's not used).

> ISC_DURING_CRANK - Function that determines the idle bypass valve duty cycle during engine cranking based on the ECT.

> INJECTOR_BREAKPOINT_VS_BATTERY_VOLTAGE - Determines switch between Low injector slope and High injector slope

> DESIRED_IDLE_AIRFLOW_IN_DRIVE - Pre-position of ISC valve for idle in Drive.

> DESIRED_IDLE_AIRFLOW_IN_NEUTRAL - Pre-position of ISC valve for idle in Neutral.

#### Changes

A few scaling labels were slightly modified, and more comments were added.

Changed DASHPOT units to Kg/Hr to make it easier to tweek the MAF_FUNCTION for idle adjustments.

> WOT_ADVANCE_VS_BP replaces ADVANCE_VS_BP. This spark adder is only active at WOT.

> SEALEVEL_LOM_SPARK_TABLE replaces ALTITUDE_BASE_SPARK_TABLE.
> ALTITUDE_LOM_SPARK_TABLE replaces LIMP_MODE_SPARK_TABLE.
> These two tables determine you base timing for all non-WOT operation except light loads below 1500. (WOT_ADVANCE_VS_RPM is the base timing at WOT). The tables are interpolated between corresponding cells for altitude corrections. Simply put, change them both by the same amount if you make changes.

#### Removals

> A9L only: STABILIZED_FUEL_TABLE was removed. The table was not used by the Air/Fuel mixture strategy.

# v2.02 release notes

This version of software has changed/deleted a few modification tags. This effort was made so that a given modification tag means the same thing across different vehicle applications. So, for example, if you are accustomed to changing HIGH_INJECTOR_SLOPE and LOW_INJECTOR_SLOPE on a 94/95 Mustang, you would use the same tags for 89-93 Mustangs (INJECTOR_SIZE and HIGH_INJECTOR_SLOPE are the same thing)

    Obsolete Modification tags
       OLD                           NEW
       ---				-----
    INJECTOR_SIZE                    HIGH_INJECTOR_SLOPE
    ACCELERATOR_PUMP_VS_TP_VOLTAGE   ACCEL_ENRICHMENT_VS_TPS
    ACCELERATOR_PUMP_FUEL_TABLE      ACCEL_ENRICHMENT_FUEL_TABLE
    ECT_HS_FAN_ON                    ECT1_HS_FAN_ON
                                     ECT2_HS_FAN_ON
    BASE_OL_FUEL_AF_RATIO            BASE_FUEL_TABLE
    STARTUP_OL_FUEL_AF_RATIO         STARTUP_FUEL_TABLE
    STARTUP_FUEL_ENRICHMENT          STARTUP_FUEL_TABLE
    STABILIZED_OL_FUEL_AF_RATIO      STABILIZED_FUEL_TABLE

#### Other changes --

1.     ECT1_HS.... and ECT2_HS... should be set to the same value for modifying fan operation.

2.     Added STABILIZED_FUEL_TABLE to A9M-A9S-A9L-series processors.

3. Changed Fuel table divisor from 8 to 8.7671233 to fix the stochiometric ratio at 14.6. The numbers were too high before. This divisor is what Ford intended. Affects STARTUP_FUEL_TABLE , BASE_FUEL_TABLE, STABILIZED_FUEL_TABLE
4. HEGO_BIAS interpretation has changes. 0 means no bias, negative numbers richen(?), positive numbers mean lean. This only effects closed loop operation.

#### Updating from v1.xx to v2.00

Uninstall the older version of the EEC Tuner software by running "Add/Remove Programs" from the Control Panel applet. This is necessary because the previous versions of the software were installed in a Directory name ShiftMaster Enterprises. v2.00 now installs to a directory named ShiftMaster. Removing the older version prevents the possibility of using v2.00 Modification files with pre-v2.00 software. Since the Fuel table interpretation has changed, this is important (v2.0 would interpret the fuel tables as leaner then you think.)

Install EEC Tuner v2.00 software by running setup.exe

Retrieve current modifications from you EEC Tuner using the new software. Check that they look OK. The modifications will be interpreted correctly by the new software, so the fuel tables should look different then the same modifications with pre-v2.00 software.

Save the retrieved modifications in a new file name for later use if desired.
