GETTING STARTED
Press “MENU” key to turn unit on. Unit will automatically turn off after
2 minutes if no keys have been pressed.
GREETING MESSAGE
The PerformAIRE
By ALTRONICS
O2 EQUIPPED
VERSION 1.* (Firmware Version)
"O2 EQUIPPED" will only appear if the unit was purchased with an
oxygen sensor.
DATA BASE #1
ET MODE Selected
Multiple Run Prediction
Wind Prediction Enabled
Second greeting message above will show the following info about the
“Setup” of the unit: Data base, prediction mode, prediction type, and
wind effect.
TAKING AIR SAMPLES
1. Place PerformBJSF in an area that will constantly expose it to
the air you will be racing in (out side of trailer).
2. Do not place your hand or any other object near the air vent while
PerformBJSF is in use.
3. Do not place PerformBJSF near soil or grass as it may pick up
additional humidity.
4. Although the PerformBJSF is reasonably durable, it can be
damaged if dropped or abused. Keep this in consideration when
using and storing the PerformBJSF.
5. Although PerformBJSF!work accurately in direct sunlight
keeping it shaded will allow it to stabilize faster.

**IMPORTANT**
Units with oxygen sensors only:
When using a unit with an oxygen sensor that is set to Oxygen Altitude
mode, the unit must remain stabile while in use. If movement has
agitated the unit it must remain stable for 15 minutes before taking air
samples. Unit does not need to have power on to stabilize!!!!
******Important******
It often takes a number of trips to the track to acquire the recommended
data in order to produce accurate results. Because of this, we suggest
using the following method until enough data has been acquired or using
the One Run Prediction Method (See Page 11).
Gasoline burning engines:
A 200’ rise in DA typically yields a 0.01sec slow down in ET and vice-
versa for a drop in DA.
Alcohol burning engines:
A 400’ rise in DA typically yields a 0.01sec slow down in ET and vice-
versa for a drop in DA.
For TS racers:
Typically the TS ratio is 3:1. This means is takes 0.03sec in the timer to
move the car 0.01sec. Use this information with the above DA change to
set up your timer.
If you read nothing else, please read
GUILDLINES FOR ACCURATE PREDICTIONS
on page 27!!!!!!!!!

KEYPAD FUNCTIONS
MENU/ON key - Turns unit ON and allows the unit to leave any current
menu and return to the MAIN menu.
▲/LIGHT key - used to scroll up and turn backlit on. The backlit can
only be turned on and off when unit is in the main menu or when
weather data is being displayed.
▼/CLEAR key – Scrolls down and is used to clear data.
3/OFF key – Turns unit off when pressed from MAIN menu. (NOTE:
OFF key must be held for at least 1 full second). Unit turns itself off
automatically if no keys are pressed for 1 minute.
ENTER/HOLD key - must be pressed after keying in a value to confirm the
value is correct. When pressed in SAMPLE AIR mode the air sample is held in
memory and can be used for data entry later on. To view the “Held” data you
can press the HOLD key when you are at the main menu.
MENUS
MAIN MENU - When unit is turned on the MAIN menu automatically is
displayed after the greeting message.
SAMPLE AIR/WIND = 1 (Wind optional)
SET UP = 2
RUN ENTRY = 3
PREDICT = 4
Hit the “MENU” key again and see:
DOWNLOAD =5
SET CLOCK =6
BAD RUNS =7
AUTO POWER OFF =8
Hit the “MENU” key again and see:
SAMPLE METHOD =9
BATTERY CHECK =0
Refer to Appendix for MENU chart
6
SAMPLE AIR/WIND
SAMPLE Wind (Optional)
After selecting option 1 a second menu prompt will follow if unit is
equipped with wind sensor:
SAMPLE Air =1
SAMPLE Wind =2
Selecting option 2 will display average wind reading along with max
wind gust: 5.0MPH 10.2Gust
Exit->Press MENU
After wind reading has stabilized, press and hold the MENU button to
exit wind readings and save wind values. The saved wind values can be
used when storing runs or correcting wind effects when predicting.
Saved wind values will automatically be displayed at appropriate
prompts and user can confirm value or change if desired.
TAKING WIND READINGS
1. Lift end of wind sensor up and sensor arm will snap into position.
When wind reading is complete, push end of sensor back to
closed position.
2. Face back of unit towards wind and note direction in reference to
vehicle (Head, Tail , Cross).
SAMPLE Air
7
By pressing "1" from the menu the unit displays all the sampled air
parameters and the PREDICTION in the following format:
DATE TIME
TEMP HUMIDITY
PRESSURE OXYGEN (if equipped) / DEW POINT or GOW VAPOR PRESSURE
ALTITUDE/CF PREDICTION (ET, TS, JET or PLATE)
The third and fourth line on the display will alternate from showing
Pressure and Oxygen to Dew Point and Vapor Pressure and Altitude to
Horse Power Correction Factor (CF). Dew Point can be replaced to
show Grains of Water (GOW). See SETUP.
Upon exiting the SAMPLE Air screen the unit will automatically save
the last sampled data as CURRENT data,. You can also Press the
“ENTER” key while viewing data. This will HOLD the data to be used
later for entering runs. To view the “Held” data you can press the
HOLD key when you are at the main menu. Therefore you can use
either the CURRENT or the HELD data when entering or predicting
data.
If the unit has been set to Auto Stable from the SAMPLE METHOD
menu the following will be displayed when SAMPLE AIR is selected:
Stabilizing XX%
Stabilizing will show the percent the unit has stabilized and will keep
increasing percentage until it is 100%, then the weather sample will be
displayed. Pressing and holding the MENU button while “Stabilizing”
will cause unit to jump out and show air data.
If Wind Correction has been enabled in the SET UP menu the user will
first be prompted to enter wind speed and direction before weather
sampling begins.
The PREDICTION will be shown in the lower right hand corner only after two
runs in ET or PLATE mode and three runs in TS mode have been stored in the
selected data base. If less runs have been stored "***" will appear in the place
of the PREDICTION value.
PLATE MODE: The predicted plate will appear in the lower right hand corner of the
screen (example: “EZ= DL12” or “EZ= F08”). If the prediction is displayed as “EZ=
8
***”, you do not have enough runs entered to make a prediction. If the prediction is
displayed as “EZ= N/A”, the prediction is for a plate larger than the largest possible
plate, or smaller than the smallest possible plate.
NOTE: Barometric Pressure
The Pressure reading is “Absolute”, which means it will NOT agree with the
weather channel or local forecast. This is due to the fact that the local forecast
is gives a corrected pressure reading that is compensated back down to sea
level. If you were to stand at your local airport and dig a hole down to sea level
the PerformBJSF pressure reading would then agree with the local airport
reading!

SET UP
By pressing "2" from the MAIN menu the unit enters SET UP. Set up
allows for configuring any one of the 10 data bases or selecting weather
variables to be displayed. Each data Base hold 40 runs.
The first menu appears...
Setup Data Base =1
Setup Weather =2
Setup Weather:
Pressing “2” displays the following menu and prompts the user to select
“1” or “2” to display Grains of Water(GOW) or Dew Point(Dp F) when
sampling the air.
Shows Grains =1
ShowDewPoint=2
Setup Data Base:
Pressing “1” displays the following screen and prompts the user to select
one of the 10 available data bases.
Select Data Base
Yes = 1 No = 2
After selecting a data base you will be asked if you want to clear all the
runs out of it: CLEAR RUNS?
Yes = CLEAR No = ANY KEY
You will now be asked if you want to rename it. Note: You can use the
default name if you wish “Data Base #1”.
To enter a new name use the “SCROLL” key to scroll the letter up or the
CLEAR key to scroll down. When the letter is correct select Yes by
pressing “1” and you will go on to the next letter. When all the letters
have been selected press the “ENTER” key to save the name.
Continue?
Yes = 1 No = 2
