Raymond,

****Warning**** This is coming from a non data geek!!!


We use a DL-1. I didn't do a lot of research on them but since the other guys were using it, it only made sense to get that. It's great when you have guys running in the same class that you can compare the data to. I think that's an import part of the decision. if you can't compare to other drivers/cars, you lose half the capabilities.

I don't know how it compares to the others, but the DL-1 has a lot of different in-put options. I'm only scratching the surface at this point. I would guess the DL-1 by itself has improved my lap times by a full second, maybe more. You can't buy a better "go fast" part for the money.

That being said, I don't find the DL-1 easy to learn. You really need someone who's familiar with it to show you the basics.

I'm sure Andy, Greg or Jeremy can give a lot more insight than I can.
