Interesting....................................... .............

Correct me if I have gotten some wrong information but can you LEGALLY have a "data logger" connected to your "ignition system"?

He explicitly said legal from Stock to TAFC. I was surprised to hear that. Data recorders permitted according to Rulebook (Section11A, pg12, Support Group 9)

Ummmm,
General Regulations; 9:2 Data Recorders
Sentence #1; Data recorders may be used to record functions of a vehicle
so long as they do not activate any function on the vehicle.

Now correct me if I'm wrong but aren't spark timing and timing retard "functions of the vehicle?

Sentence #4; Fifth-wheel sensing devices prohibited on all vehicles.

Again, correct me if I'm wrong but wouldn't a driveshaft sensor be considered a "fifth-wheel sensing device"? And even if it's not, when did they become legal?

I think that the Tech Dept. should re-read General Regulations section 9:1 and 9:2 before it makes any determinations regarding what it allows some of it's sponsors to sell to the Racers!

It says:
  • Program a specific timing action at any point or range during a run to control conditions you have identified by feel or via data logging.
  • Program time or gear based rev limits throughout the run to prevent an overrev from tire spin or even a missed shift.

Billy I have a grid and the data logger does not control any of the functions. You have to program the functions into the grid. Not because I use one but that is how would interpret it. BP

This cats out of the bag already. MSD will add features/upgrades to their products. Why would NHRA stop them? A Rulebook gray area...
