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 6.*
"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 or black
probe while PerformBJSF is in use.
3. Keep PerformBJSF out of direct sunlight.
4. Do not place PerformBJSF near soil or grass as it may pick up
additional humidity.
5. Even though the PerformBJSF's sensors can stabilize very quickly,
residual heat left in the enclosure when the PerformBJSF is moved
from one environment to another may take more time to dissipate.
Example: When you arrive at the track and take the PerformBJSF out
of your 70-degree transporting vehicle and put it in the 90 degree outside
air, you must let it sit for fifteen minutes before taking a reading. During
this time the PerformBJSF enclosure and black probe will stabilize
with the environment and allow it to take extremely accurate readings for
the rest of the day. Allow time appropriately for differences in
4
temperature. If the PerformBJSF is OXYGEN SENSOR equipped,
allow twice as much time to stabilize.
UNIT DOES NOT NEED TO HAVE POWER ON IN ORDER TO
STABILIZE!!!!!!!
6. Although the PerformBJSF is reasonably durable, it can be
damaged if dropped or abused. Keep this in consideration when using
and storing the PerformBJSF.
7. For best results only turn PerformBJSF on when taking a reading.
**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 above-
recommended data in order to produce accurate results. Because of this,
we suggest using the following method until enough data has been
acquired.
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.

KEYPAD FUNCTIONS
MENU/ON key - Turns unit ON and allows the unit to leave any current
menu and return to the MAIN menu.
SCROLL key - used to view runs that have been stored in the data base.
CLEAR/OFF key – Turns unit OFF when pressed from MAIN menu and
allows runs to be deleted from the data base and allows the user to
reenter a value if the wrong key was pressed.
ENTER/HOLD key - must be pressed after keying in a value to confirm
the value is correct. When pressed in CURRENT DATA mode the air
sample is held in memory and can be used for data entry later on.
MENUS
MAIN MENU - When unit is turned on the MAIN menu automatically is
displayed after the greeting message. The user can make of the six
following choices at this point:
SAMPLE AIR = 1
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:
PAGER SETUP =9 *
BATTERY CHECK =0
* Paging Option in no longer available with portable PerformBJSF systems.
Refer to Appendix for MENU chart

SAMPLE AIR
By pressing "1" from the MAIN 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 VAPOR PRESSURE
ALTITUDE/CF PREDICTION (ET or TS)
Pressing the “ENTER” key while viewing current data will HOLD the
data to be used for entering runs. The third and fourth line on the display
will alternate from showing pressure and oxygen to dew point and vapor
pressure and Altitude to Correction Factor (CF).
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!
The PREDICTION Multiple Run Mode will be shown only after two
runs in ET 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.
7
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. Each data Base hold
40 runs.
The first menu appears...
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
After selecting a data base you can exit out of SETUP if you have
already previously configured it and do not wish to make any changes.
After selecting a data base the following is displayed:
ET MODE = 1
TS MODE = 2
Press 1 OR 2
By pressing "1" sets the unit to the ET MODE. This means all runs
added to the data base will be stored in the ET section and the
PREDICTION will be an ET computed from the stored runs and the
present ALTITUDE (DA or OA).
8
By pressing "2" sets the unit to the TS MODE (Throttle Stop Mode).
This means all runs added to the data base will be stored in the TS
section and the PREDICTION will be a TS or timer setting computed
from the stored runs and the present ALTITUDE.
After pressing "2" another menu is displayed as follows:
TS MODE SELECTED
index = 9.90
CHANGE?
YES = 1 NO = 2
If the user presses "1" the following will be displayed:
ENTER INDEX
Now the user can enter an index, such as 8.90, then he must press the
ENTER key.
Select Method
For Prediction
Multiple Runs =1
One Run =2
Multiple Runs:
When the multiple run prediction method is selected, predictions are then
calculated from the runs stored in the data base.
Predict with
DA=1 OA=2
CF=3 VP=4
Now you must choose which weather variable to reference your
prediction against. The standard is to use DA or OA (if the unit is
oxygen sensor equipped), but you can select CF or VP if you wish.
One Run:
When One Run prediction method is selected you must set your base run
and performance ratios. Set Base Run=1
Set Pred Value=2
View Values=3
Done =ENTER
9
Set Base Run:
Your base run data should be taken from a “good run” or your last “good
run”. You can update this data as you wish.
Enter Base Run
DA=
ET=
Timer= (if in TS mode)
Temperature= (if fuel type=Alcohol)
Humidity= (if fuel type=Alcohol)
Set Pred Values:
Set Pred Values allows you to select your gas type and your DA to ET
and TS to ET ratios. Select
Gas=1 Alcohol=2
Now you will be prompted to choose between preset ratios or allowed to
enter custom ratios. Preset Ratios=1
Custom Ratios=2
Custom Ratios: Enter DA Ratio
Enter how many foot of Altitude it takes to move you vehicle 0.01sec in
ET. (Ex: 150 means it takes 150’DA to make ET change 0.01sec)
Enter TS Ratio
Enter ratio that it takes to move ET of vehicle 0.01 sec. (EX: 2 means it
is a 2:1 ratio or takes two 0.02 to move car 0.01 in ET)
View Values:
Allows you to view your base values and ratios.
Predict with
DA=1 OA=2
CF=3 VP=4
Now you must choose which weather variable to reference your
prediction against.
