Accuracy of aeroforce interceptor gauge
How accurate is the inteceptor gauge at clocking 1/4 mile. It says i ran a 13.9 with gm stage 2, K&N CAI, &magnaflow catback exhaust.

It measures the 1/4 mile at the wheels -- so if you spin the wheels at all then you mess up the reading... I think its more of a guess than anything, but I have no proof one way or the other to support this

i just went to the aeroforce interceptor website and it says as long as theres not wheel spin and you havent changed the stock tire size then it should be fairly accurate. so i'm guessing my 13.9 is accurate. Now i'll see how much faster it gets when i put on the OTTP stage 2 instead of GM stage 2

PERFORMANCE. This selection will allow you to measure 0-60 mph (100
Km/hr in the metric version), 1/8 mile and ¼ mile performance with speed.
Selecting this option will take you to a screen saying “vehicle must be at 0
mph before starting”. This indicates that the timer will not start until the
vehicle is fully stopped, and starts moving. Once the vehicle starts moving,
the screen colors will invert and the timing will commence. Once the ¼ mile
mark is reached a summary screen will appear, showing ¼ time and speed, 1/8
mile time and speed, and 0-60 time. If you do not run a full ¼ mile, the
measurement will eventually time out and indicate the 1/8 mile stats as well as
0-60 once the timeout occurs. This timeout may take several minutes so it’s
best to coast a full ¼ mile even if all you want is 0-60 or 1/8 mile times.
When finished viewing the results hit the right button to return to the main
menu. These statistics can be viewed again by choosing the “Statistics” menu
option described below. Please note that this measurement’s accuracy is
dependent upon the accuracy of the speed signal. If the vehicle has non-stock
sized wheels or the rear axel ratio has been changed, and the vehicle’s speed
sensor has not been recalibrated or the PCM reflashed accordingly, the accuracy of these measurements will be effected. Another way of stating thisis that if your speedometer is inaccurate, so will be these measurements. Inaddition, wheel spin will effect 1/8 and ¼ mile e.t.’s, giving inaccurately
lower times.
