If your driving a Subaru you can call up Rocket and pay to have Pats diff control setup.

There was this great off season where like 3-4 Subaru guys that were all competing against each other all did just that. And if I recall you pay for the computer AND then you pay for the maps. I think it was 2500 and 1500 respectively. That is the Beauty of AWD.

That's the beauty of the monetization of this amateur sport. More parts means more opportunities to make more dough...

Makes you wonder how and old mere 2wd car can go out and beat all but a couple of the "sky is the limit" cars...
Like the Ozzie in the little 1.6 fwd thing with a boring clutch plate diff.

Do you think all the AWD Ess Pea guys need to buy better maps?

As someone who has begged for people to group together to amortize the labor you expend to develop such "parts", I'd think you'd be a little more sympathetic to someone seeing a potential improvement, developing the improvement and selling it.

And yes, the Subaru DCCD can definately benefit from better maps geared to competition use. Whether it worth the development costs to have different maps based on different surface conditions and tires, that is only something the competitor can answer. I've found that a single good base map and a bias adjustment knob gets us most of the way there with very little cost.

And the cost thing? Well, there are limited dollars and hours. Part of our job as competitors is to figure out where they are BEST applied. More often than not, the answer should be driver training and seat time (and the vehicle expense that goes along with it).

RE: diff mapping, cost and impact

I don't know the today's cost of the Gems Diff controller but it used to be around $1500 and came with "standard" maps. At the time, you could buy the software key for $400, which allowed you to create your own maps, as many as you'd like. However, Gems has killer customer support and will usually send you multiple maps to try (assuming you've bought the software key). They have hundreds of maps from various driver/car/rally combos.

A diff map makes a material difference to stage times and well worth the relatively minor investment.
