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.
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.
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.
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 TEMP PRESSURE ALTITUDE/CF TIME HUMIDITY OXYGEN (if equipped) / DEW POINT VAPOR PRESSURE PREDICTION (ET or TS) Pressing the “ENTER” key while viewing current data will HOLD the data to be used for entering runs.
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”.
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.
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.
Wind Prediction: If you have chosen Multiple Run Prediction you will be prompted to select to use wind correction into you ET or TS predictions: Predict w/Wind? PRESS 1=Y 2=N If you enable wind correction you will be prompted to select a vehicle type: Select Car Type Dragster=1 Door =2 Roadster=3 Next you can adjust the wind effect. Adjust Effect? Press 1=Y 2=N Wind factors have been programmed to correct prediction for wind based on speed and direction of wind.
RUN ENTRY By pressing "3" from the MAIN menu the unit displays the following: VIEW/DELETE RUNS ADD RUNS =1 =2 TSR or RATIO/SLET =3 =3 “TSR” (throttle stop ratio) is only displayed if the unit in TS MODE and more then two runs has already been stored. Pressing "3" displays the throttle stop ratio. “RATIO/SLET” is displayed only if the unit is in ET MODE and more then two runs have already been stored. Pressing 3 displays your SEA LEVEL ET and your ALT/ET ratio.
Enter Run Info-> DA=1000 (Example) 1000’ ET= ET= TS= The DA or OA will already be loaded. You should enter a 1000’ ET, a final ET, and TS. The 1000’ ET is optional and is used for run completing. You do not have to enter every run with a 1000’ time in order to use run completing. The TS will only be entered if the unit is in TS MODE. To use run completing press the ENTER key when prompted for the final ET. If manual entry is desired you must select number 3. After selecting 3 the following is displayed.
RUN COMPLETION In order use the run completion program effectively at least one previous run must be entered into a data base with a 1000’ ET. To use run completion all you need to do is enter the 1000’ et of the run you want to complete and then when it asks you to enter your final ET= simply press the ENTER key without any value. You will then see a Run Completing! message appear followed by ET=10.203 (example) your completed ET.
DOWNLOAD By pressing “5” you will begin downloading into a personal computer if you have purchased that option. To install software: Place DISK 1 in drive d:\ and run SETUP. Follow the instructions on the screen to finish installation. 1) 2) 3) 4) 5) 6) COMPORT button - To download PerformBJSF connect supplied cable to unit and to serial port on back of computer. You can use serial port 1 or 2.
Sea Level ET OA: ET car will run at 0’ oxygen altitude. (Optional) Alt Ratio DA: Time in seconds ET will change with a 100’ change in density altitude. Alt Ratio OA: Time in seconds ET will change with a 100’ change in oxygen altitude. (Optional) TS Ratio DA: Time in seconds Throttle Stop will need to change in order to change ET of car 0.01sec in density altitude. TS Ratio OA: Time in seconds Throttle Stop will need to change in order to change ET of car 0.01sec in oxygen altitude.
SET CLOCK By pressing "6" from the MAIN menu the unit will prompt you to enter the DATE and TIME. BAD RUNS By pressing “7’ from the MAIN menu the unit will display any runs that do not “fit” with the rest of the data. These runs will not be removed; you will have to clear them out of the data base yourself. Example: Run #1: DA = 1000 ET = 10.10 Run #2 DA = 2000 ET = 10.20 Run #3 DA = 1800 ET = 10.21 With these 3 runs in a data base BAD RUNS would display: Run 3 does not fit.
BATTERY CHECK By pressing “0” you will the following will be displayed. POWER=XX% 0 to 100% is displayed to show the amount of battery life left. THE BATTERIES A 9-volt battery powers the PerformBJSF. A fully charged (DURACELL or ENERGIZER) battery will operate the PerformBJSF for approx. 12 hours. After approx. 12 hours of use the LOW BATTERY message will be displayed when you are sampling the air. At this time the battery must be replaced. Rechargeable batteries can be used.

GUIDELINES FOR ACCURATE PREDICTIONS For ET predicting it is recommended that 5 to 6 Good Runs be entered into a database and that there is a span of at least 1000’ feet in DA or OA between the runs. Ex: Typical Data Run #1 1223’ 10.20 Run #2 1301’ 10.204 Run #3 1956’ 10.236 Run #4 2000’ 10.237 Run #5 2245’ 10.249 Run #6 2269’ 10.25 For TS predicting it is also recommended that 5 to 6 runs be entered into a database and that there is a span of at least 1000’ feet in DA or OA between the runs.
