NO. BUT IF THERE IS A MODULE OR PROGRAM FEATURE THAT IS NOT WORKING PROPERLY I WILL FIX IT AND SEND OUT THE NEW PROGRAM VERSION

QUARTERMASTER PROGRAMS ARE AVAILABLE FOR DOWNLOAD ONCE PURCHASED AND DOWNLOAD LINK IS GOOD FOR 30 DAYS

SIMPLY CONTACT QMDRS (QUARTERMASTER DRAG RACING SOFTWARE) THROUGH THIS WEBSITE AND WE WILL REACH OUT TO THE CUSTOMER WITHIN 24 HOURS.

EXISTING DRAG RACING SOFTWARE PROGRAMS ARE DESIGNED TO HAVE THE USER INPUT HIS CAR'S HORSEPOWER AND TORQUE AT VARIOUS RPM'S FROM A RECENT DYNAMOMETER TEST ALONG WITH TRANSMISSION GEAR RATIOS, CAR AND DRIVER WEIGHTS AND TIRE SIZES. THE PROGRAMS WILL THEN CALCULATE AN APPROXIMATE QUARTER MILE ELASPED TIME AND CORRESPONDING TRAP OR TERMINAL VELOCITES AT 60, 330, 660, 1000 AND 1320 FEET AND PROVIDE THE USER WITH A SIMULATED TIME SLIP JUST LIKE YOU WOULD RECIEVE AT YOUR LOCAL DRAG STRIP.

QUARTERMASTER'S DRAGY-DYNO PROGRAMS DO THE EXACT OPPOSITE. QM DRAG RACING PROGRAMS TAKE THE ELAPSED TIMES AND VELOCITIES OFF A DRAGY 1/4 MILE PERFORMANCE REPORT OR A TIME SLIP FROM A LOCAL DRAGSTRIP AND REVERSE ENGINEERS THAT DATA INTO A FULL PERFORMANCE ASSESSMENT OF YOUR CAR PRESENTED WITH EASY TO UNDERSTAND TABLES AND CHARTS

ABSOLUTELY. THE DRAGY REAMAINS THE NUMBER ONE USER-FRIENDLY GPS BASED PERFORMANCE METERS ON THE MARKET. IT CAN DELIVER UP TO 1/100TH SECOND PRECISION USING HIGH-SPEED SATELLITE TRACKING. IT USES NO WIRING, NO OBD2 DEVICE AND HAS FULL COMPATABILITY ACROSS ALL VEHICLES. FOR THE MONEY NOTHING ELSE COME CLOSE.

THE POPULARITY OF THE DRAGY GPS DEVICE AND THE GROWING POPULARITY (NOTORIETY?) OF THE DIY 0-60 AND ESPECIALLY THE 60-130 ACCELERATION TESTS BROUGHT QUESTIONS AND DISCUSSIONS ON SEVERAL CAR ENTHUSIEST FORUMS AS TO WHETHER THE 60-130 ELAPSED TIME COULD BE USED TO ACCURATELY DETERMINE A CAR'S HORSEPOWER OUTPUT.

IT CERTAINLY CAN....AND VERY ACCURATELY.

THE QUARTERMASTER PROGRAMS ARE DESIGNED FOR THE INPUT OF THE DATA STRAIGHT OFF OF A DRAGY PERFORMANCE REPORT.

VERY EASY TO DO.

IN THE REAL WORLD OF DRAG RACING; NOT EVEN CLOSE. THE DRAGY WEBSITE HAS RECENTLY COME CLEAN ON JUST HOW ACCURATE THE DRAGY CAN BE. IT IS DESIGNED TO HAVE AN ACCURACY OF .01S WHEN IT CAN OPTIMIZE ITS ANTENNA AND RECIEVE SIGNALS FROM THE 4 MAIN GLOBAL NAVIGATIONAL SATELLITE SYSTEMS AKA GPS, GALILEO, GLONASS AND BEIDOU "SIMULATANEOUSLY" FOR A TOTAL OF 32 SATELLITES.

PURE THEORY. NEVER HAPPENS.

THE REALITY IS THAT DRAGY ROUTINELY TRACKS WITH BETWEEN 8 AND 12 SATELLITES AND NOW SAYS ITS NEW DRG70-C MODEL OPERATES AT "UP TO" 25HZ WITH "UP TO" 32 SATELLITES AND CAN COME TO WITHIN +/- .03S OF A MODERN TRACK TIMING SYSTEM THAT IS HARD WIRED AND CERTIFIED TO MEASURE WITHIN +/- .0005S. IN OTHER WORDS A TRACK TIMING SYSTEM USING AN ACCUTIME II SYSTEM IS 60X MORE PRECISE THAN A DRAGY IN TERMS OF TIMING RESOLUTION.

1) IMMEDIATE SEAT OF THE PANTS SENSATION: THE FIRST BURST OF ACCELERATION YOU FEEL WHERE TORQUE, TRACTION AND CONTROL ALL MERGE TOGETHER. 80% OF HARD LAUNCHES HAPPEN IN CITY DRIVING GOING LIGHT TO LIGHT AND RARELY EXCEED 30 MPH.

2) LESS INFLUENCE BY AERODYNAMIC AND ROLLING RESISTANCE : : AERODYNAMIC AND ROLLING RESISTANCE HAVE VERY LITLE EFFECT ON ACCELERATION UP TO 30-40 MPH. BY 55 MPH AND CERTAINLY BY 60 MPH AERODYNAMIC AND ROLLING FORCES ALONG WITH SHIFTING STRATEGY BEGIN TO EFFECT A CAR'S ACCELERATION GREATLY.

3) FAR MORE REPRESENTATIVE OF REAL-WORLD DRIVING: CAR MAGAZINE TESTING PROGRAMS ARE ADOPTING THE 0-30 MPH METRIC AS FAR MORE MEANINGFULL THAN A 0-60 PULL TO REFLECT MORE PRACTICAL AND SAFE CITY DRIVING

1) CAPTURES THE TRANSIENT VIOLENCE BEYOND THE AVERAGE ACCELERATION: THE JERK METRIC EXPOSES THE SEVERITY AND ABRUPTNESS OF CAR CHASSIS REACTION - AND INCLUDES THE VIOLENT AXLE AND DRIVESHAFT TORSIONALS THAT RESULT IN THE FIRST .25S.

2) IT ALLOWS YOU TO NOT ONLY QUANTIFY THE SEVERITY OF THE VIOLENT LAUNCH EVENT BUT HOW QUICKLY THOSE FORCES RAMP UP TO PUT HP TO THE GROUND.

SEVERAL OF THE QM DRAGY-DYNO PROGRAMS HAVE THE REQUIRED HOOK RATE CALCULATION MODULE THAT IS NEEDED TO ASSESS HOW CLOSE A CAR IS TO LIFTING ITS FRONT TRIES OFF THE GROUND. ITS IS QUANTIFIED WITH A LIFT RATIO. ALL YOU HAVE TO DO IS INPUT THE REQUIRED DATA FROM A 1/4 MILE DRAGY PERFORMANCE REPORT OR A DRAGSTRIP TIME SLIP AND THE PROGRAM WILL TELL YOU WHAT HOOK RATE IS REQUIRED FOR LIFT OFF AND HOW MUCH HOOK RATE IS ACTUALLY AVAILABLE

THE R^2 TERM YOU SEE CAN BE LOOKED AT AS A SCORE THAT EXPRESSES THE FIT "SCORE" BETWEEN THE PROGRAMS PREDICTED VALUES AND THE ACTUAL VALUES FROM THE 1/4 MILE RUN. R^2 = 1 MEANS EVERY PREDICTED VALUE MATCHES THE REAL-WORLD RESULTS.

TO EXTRACT THE 7 SEPARATE 10 MPH INTERVALS THAT MAKE UP THE 60-130 ELAPSED TIME REQUIRES THAT THE R^2 (COEFFICIENT OF DETERMINATION) LISTED ON THE PERFROMANCE ALIGNMENT PLOT BE NO LESS THAN .9985 TO MAINTAIN THE +/- .003S TOLERANCE THAT IS CALLED FOR
