That ARC Module or the previous use of that box, within a set period of time can be detected by the tester that you mention. Every DD was given one.

But, you can loan them yours if you wish. MSD Part number 89973.

I think that people are giving these components a lot more credit than they deserve.

Nothing is impossible. With the right amount of money and time I am sure anything can be compromised. We work hard to give NHRA the tools to ensure that our products haven't been modified.

I agree Robin, the grid gets much more credit than it probably deserves. You really need to run a racepak in conjunction with a grid to really maximize all the advantages it has to offer but theres still no place for that in the Stock Eliminator game. Especially on carb engines. There shouldnt be 8 egts and 2 O2's on a carb stocker motor, because the technology you need to have to utilize that stuff isnt stock. The grid can still be advantagous at the starting line when the track is going away but that should be only for super stock. And there should be zero cars with wires on their rear ends period, idc how much you spent on your car. But Holley has provisions for sensors to "help" your high horsepower stocker launch on marginal tracks.

But here is where the water gets muddy Robin. Plimpton innovations has techonolgy out that works with a holley system that acts as a weather station hard wired into your ECU. And no, this will not work with a grid as you need inputs and outputs for this stuff to work. In the simplest terms, you can get a baseline run in different weather conditions and use this new tecnology to add and pull timing and fuel during a run to maintain the same speed as your baseline. In more or less words, you can write your dial with a sharpie marker on your window for the weekend. The people I work with are into the turbo scene on small tires and crap who roll their eyes at us stock and super stockers. But all the sensors they are using to make their high HP cars work on awful tracks are the same stuff guys with EFI could be using in the NHRA lanes. And theres noone to police it.
