How do you separate the data recorder from the EFI on a new car?
I would be more worried about ignition.

You don't need a "data recorder" to run the EFI!

But isn’t the data recorder part of Fast and Holley Systems?
Older cars yes I get that .

As far as I know, all aftermarket ECUs that are accepted by NHRA have built in datalogging capabilities. And, unlike a Racepak which cannot datalog without an SD card, ECUs have integrated memory, and don't need an external storage device for data acquisition. An MSD Grid is an ignition box that can also data log, and you can't tell someone that their ignition box can't be hooked up during eliminations. I know that with a Holley ECU, you can program it to begin data acquisition automatically, whether it be RPM based, TPS value, so no need to even press a button to do so. Unfortunately there is no one true answer to the issue at hand. Should the Grid have been allowed in Stock/Super Stock? IMHO probably not. If they outlaw it, there will probably be an angry mob, so that alone may deter the decision to take it away.

Ok, point taken but can an "NHRA accepted aftermarket ECU" without a "grid" make elapsed-time altering decisions on it's own?

P.S., this is why Doug won't let me have my laptop!

The Grid system is only capable of making "on the fly" changes if it is equipped with an accessory that is explicitly illegal. As a bonus, that accessory will leave a "breadcrumb" in the system to let an inspector know that it has been used somewhat recently.

There are many standalone products that will do traction control that are more easily hidden and do not communicate their presence.

just to add to your comments about the grid, they may not apply to all grids as it has been rumored for years, the existence of a "texas" grid which allows you to ride the dots and leaves no breadcrumbs.
