Here's the deal for you guys waiting for updates....

The first test session/track day with CBRD at NJMP thunderbolt track went very well, except for the rain in the afternoon (both cars being tested only brought slicks with them). We were not able to get 'official' data from this first session for multiple reasons which I won't get into. I will tell you that we were able to knock off over 3 seconds per lap on one of the evo's there. The other evo was doing shake down runs and was extremely inconsistent with it's lap times, so no real data there.

We went to go do more testing at NJMP on the lightning track, except the evo's that we were testing before didn't show up.... actually no evo's showed up- so no data there.

I can tell you guys that I have done testing with people and have seen consistently great results. One of my testers/clients is a racer in Australia who WON his division/class using our flashes. His type of racing is somewhat of a sprint/time attack style. Congratulations Dean!!

I am now working with a shop in Poland that specializes in all forms racing, but specifically tarmac rallying- this should be fun indeed.

The results from the first NJMP test are pretty consistent with what we normally see- a good 2-4 seconds off depending on driver, conditions, blah blah blah.

Edit: ACD-Tuning is currently designing a new package for evo owners that don't race competitively. This will be a cheaper option that will include map(s) which will be more encompassing and not quite so specific. We are determined not to exclude anybody from this great development!

 

Will any of the ACD mapping have any effect at all if ther is no difference in wheel speed from front to rear wheels?

 

Yes, it will. There are many variables other than wheel speed that the ACD unit looks at.

 

What I mean is, will it change the 50/50 bias before wheel slippage happens? I know in stock form, no matter what the ACD setting is, only really functions after wheel spin, and on a road course where wheelspin is rarely an issue, would mean that the ACD system really is not doing anything until you have a loss of traction. There is a big difference between a biasing center differential and our ACD system, which if I remember correctly can not physically transfer over 50% to the rear wheels anyway.. Mabye someone with more knowledge then myself can elaborate on this?

 

You are correct, it will always reamin 50/50.

There are many maps that get altered when we flash an acd unit--- they deal with steering input, pump pressure, lock up percentage, slip percentage, g-force, etc. By altering these maps, we are able to induce the ACD to be 'active' sooner rather than waiting for wheel slippage.

I hope that helps a bit

On a side note... Motec, Gems, etc wouldn't have spent the time developing their own control units and selling them for crazy amounts of money if it didn't work.

 

Very interesting. I like the option of being able to just change 1 setting.

 

That's exactly why we sell the flashes the way we do. From our testing, we've realized you need maps for different types of racing- not three maps for one type of racing. The reason for different maps comes down to surface, speeds, types of turns, and vehicle mods.

Most people will autox, road race and DD...one more than the other. This is why I find it important to leave a stock map on the vehicle- safety and inclimate weather. I only recommend 3 tuned maps for straight up race cars that don't see snow, etc. Of course we have maps for inclimate weather- but that's a different topic.
