I had not heard of the ARC referenced above so I looked it up. For those that don't know what the MSD ARC linked with the Grid can do, this is from MSD's website:
"OVERVIEW Now there is even more control with the PN 7761 module for the Power Grid System Controller. This module sets rpm limits based on slew rate (rpm acceleration) or based on time since launch. All of this is programmed seamlessly in MSD View. The ARC module stands for Advanced RPM Control, it basically allows your race car to remain consistent, pass after pass, controlling your engines rpm curve during a pass. This helps you get down the track quicker and far more consistent. By using the MSD View software we can control the rpm down to a hundredth of a second and control the driveshaft speed for maximum traction. We can also pull out timing for a split second should we encounter tire slip. Set 3 different timing Retard curves and a Rev Limit Curve to control wheelspin." Nice video explaining the system here: Basically, it appears you set the driveshaft rpm curve in the Grid for a given ET, dial in and like magic you run within a hundreth of your dial in.

General Regulations; 8:3 and 9:2. It isn't legal the way that I read it.

I pulled on the scales one year during TT's at the US Nationals. At the time they had hired some young guy to look at electronics. He looked under my car and noticed a drive shaft sensor. He ask me where that was going to. I told him the ECU. I was busted. He had me take it off and hand it to him the next time I came across the scales. At the time ARC was not invented, but I was informed it's always been against the rules to tie your engine management to a counter (Drive Shaft Sensor). If there is no recorder (Racepac), there should not be a drive shaft sensor on the car. ARC will not be of much use without some way of counting speed/distance. I have installed many ah systems for S and SS guys and usually Drive shaft sensor comes up. I always relay what happened to me and I always get the same reply "The heck with that then" !

Jeff, the way that I've always understood it, if you have a "data logger" (racepack), you can't have anything between it and your ignition box. The Grid goes between your "data logger" and your ignition box and lets them communicate with each other.
If I'm incorrect, I'm sure someone will let me know.

Hi Billy. I think the original intention of that was so you didn't have to buy multiple sensors for each system.

The ARC module is already spelled out as being prohibited in Sportsman categories. I can’t imagine any sort of “traction control” being very consistent. Killing power, especially if trying to replicate a curve, may be too “stop and go” for it to work well in a bracket racing scenario.

Dont feel bad. I had to look that up too. I had no idea what the ARC module did. I guess I am old school. If I cant win without electronics or cheating then I dont get to. My deal is to cut a light and run the dial. I work real hard to do that. I am not a "hitter" but I do go some rounds and have finshed top 10 in the division 2 out of the past 4 seasons. I also had a divisional win in 22. Personally I dont think there is many out there cheating.
