EGR_MULTIPLIER

1

  • #

    EGR multiplier

This is a gross scaling adjustment for the flow rate of a given EGR valve. Use a number larger then one to proportionately add more recirculated exhaust gas to the intake charge. Numbers less then one reduce the EGR flow.

For example, setting EGR_MULTIPLIER to 0.75 would deliver three fourths the amount of exhaust compared to stock. A setting of 1.5 would deliver 1 and a half times the EGR flow. Don’t know why you would use this, but its fun to change the values and log EVP sensor output (pin 27).

EGR_TYPE

  • 0

    # EGR type (0=sonic, 1-PFE, 2=none)

Set to 2(none) to remove the EGR related error codes for a removed or non-functioning EGR. The effect on fuel mixture and ignition timing is unknown—probably stays exactly the same.

The Purge canister solenoid still works when the Thermactor and EGR are set to none. The Purge Canister solenoid opens at off throttle, car warm, and running for 5 minutes or so.

The _ON must be set higher then the _OFF for this function to work. The engine cuts out when the speed on the speedometer reaches the speed set with SECOND_SPEED_LIMITER_ON, the engines starts running after the speed falls off to SECOND_SPEED_LIMITER_OFF

Doesn’t seem to do anything. Possibly used on automatic equipped mustangs, or when the car is under/over operating

temperature.

_ __ _ The _ON must be set higher then the _OFF for this function to work. The PCM cuts fuel delivery in half when the engine speed reaches the RPM of the _ON value. Fuel delivery remains cut in half until the engine speed drops below the RPM set in the _OFF speed.

    Max RPM (no fuel)

Cuts all fuel when this RPM is reached. Harsh rev limiter. Avoid its use.
