LE1/LE2 Shift/warning lights (LED 1/LED 2)
The e-boost2 has 2 LED outputs that can be used as shift lights or boost level warning lights. These LED outputs can be configured to turn on and off at any boost pressure or engine RPM. Within the LE1/LE2 menus there are 5 parameters bOn (Boost pressure on), bOF (Boost pressure off), rOn (RPM on), rOF (RPM off) and rFL (RPM flashing).
Between the on and off values the LED will be illuminated. If the bOF or rOF is set to zero there will be no off and the LED will remain illuminated until boost or RPM drops below the bOn or rOn value.
You can also set a flashing warning RPM value rFL (RPM flashing) at which the led will flash until rOn is reached. Once rOn is reached the LED will turn on solid. rFL must be set to an RPM less than rOn. Setting rFL to zero will disable the flashing output.
Boost values are entered in the units currently selected for boost pressure display. RPM values are entered as RPM x 100 e.g. if 5000 RPM is the desired setting then input 050. If using a boost setting, RPM values should be set to zero to turn them off. If using a RPM setting the boost parameters should be set to zero to turn them off.
The four wires associated with these two outputs are wired into a 4 pin plug located beside the main harness 8 pin plug. A single or double LED accessory kit is available from Turbosmart that plugs directly into the eboost2 LED output with no additional wiring necessary.
If rOn, rOF, bOn and bOF values are entered on 1 LED, the LED will illuminate only when the RPM set points have been reached. The boost values are redundant.
AL (Audible alarm)
The e-Boost2 has an audible alarm function that sounds the internal buzzer once a certain boost pressure or RPM is achieved. The audible alarm is factory set to 15 psi (1 bar or 100 kPa) but can be programmed for any boost pressure or RPM. Within the AL parameter there are four options bOn, bOF, rOn and rOF.
The boost setting on (bOn) and off (bOF) values are entered in the units that are currently selected for display. Between the bOn and bOF values the buzzer will be activated.
The RPM setting on (rOn), and off (rOF) are entered as RPM x 100 e.g. if 5000 RPM is the desired setting then input 050. Between the rOn and rOF values the buzzer circuit will be closed.
If the bOF or rOF is set to zero there will be no off and the buzzer circuit will remain closed until boost or RPM drops below the rOn or bOn value. If using a boost setting RPM values should be set to zero to turn off or visa versa. Setting these parameters to zero will disable them as parameters.
If rOn, rOF, bOn and bOF values are entered, the alarm will sound when either the boost or the RPM value is reached and will turn off when the boost or RPM drops below the set point or both values reach there respective bOF and rOF values.
dS (Delayed switching)
This function is for use with set point switch logics ISP/ESP/SSA/SSB and is designed to create a delay between set point switching and activation. The time delay will be between when a subsequent set point is switched and when it actually changes i.e. the current set point will continue functioning until the time delay has elapsed. dS1 in boost group 1 applies to the time delay when switching to SP1, dS2 in boost group 2 applies to the time delay when switching to SP2 and so on. To use time delay between set point switching and activation, dS must be ON. In the SETUP Parameter Menu you can activate or de-activate this function. If this function is de-activated all menus relating to the time delay are hidden from the Boost Menu i.e. dS1 – dS6 in respective boost group. Once dS is activated in the SETUP Parameter Menu, you can enter the delay time in the Boost Group.
Note: Activating SSC/SSD and SSE also brings up the dS parameter in the boost group. Refer to section 5.6 for further details on the set point switching logic and what this parameter applies to.
COr (Boost correction)
This function is use to reduce or eliminate boost drop off at high RPM. Switching this function on will display the boost correction menu in the boost group menu. This function is best performed on a chassis dyno where the graph of the boost curve can be displayed and accurately interpreted.
The boost correction function requires 3 parameters to work; the START RPM, the END RPM and the correction factor.
START RPM (RP1): This is the engine RPM at which boost begins to drop off.
END RPM (RP2): This is the engine RPM at which you want to turn off the boost correction function, normally set at redline.
Correction factor (FAC): The percentage at which boost is dropping off between the START and END RPM.
The following boost curve shows that between 5000 and 7000 RPM, the boost drops off from 15 PSI to 10 PSI.
