Davis Technologies’ founder and mechanical wizard Shannon Davis has done a lot of groundbreaking things in his many years of involvement in sportscar, circle track, and drag racing. But, he’s arguably never been more excited about the launch of a new product (or products, we should say) than he is this week with the public unveiling of his newest iteration of circle track traction control units.
Utilizing modern hardware technology, Davis has completely revamped his circle track traction control units from top to bottom — they’re faster, more accurate, and smaller…in some cases, much smaller. As an added bonus that wasn’t available before, they are fully upgradeable at home by the end-user via a mini-USB port on the case, making firmware updates a cinch.
“We’ve been constantly working on the circle track units — as the processors have gotten better, we’re able to do higher level math,” Davis explains. “This is a whole new lineup like nothing we’ve ever done. It’s the same basic premise, but the processing power, the touch screens, the adjustability, the ease of use, online updates and upgrades, it does it all.”
Superseeding the TMS traction control units released in 2011, the new lineup starts with the CT-1, which is non-self learning, features a built-in accelerometer, performs real-time corrections, has built-in acquisition, individual cylinder control, a built-in LCD display, and has progressive output.
The CT2-SL brings self-learning and Bluetooth connectivity to the table. Self-learning, of course, is the units ability to “learn” the average rate of acceleration (engine rpm) and detect sudden spikes. If it sees sudden rates of rpm change (in essence, tire spin) beyond its learned rate, a correction in engine timing is made. With this feature, the racer doesn’t have to try figuring out the rate of change and set a threshold. With four triggers per rotation of the crankshaft, the system is updating 400 times per second at 6,000 rpm.
The CT3-SL, CT4-SL, and CT5-SL become progressively smaller in size, adding remote LCD compatibility (an add-on option). The top-of-the-line CT5-SL comes in at virtually the size of a flash drive and is supplied with a remote LCD for setup and updates.
Using the CT3-SL directly alongside an older TMS-5500-SL on Davis’ engine distributor simulator, the rate at which the new CT device not only catches rates of change, but reacts and adjusts timing retard is noticeably evident. Davis is confident the benefits will be measured in tenths of a second per lap by the racer, and could completely change the face of the racing venues where traction control systems are in use.
It’s just another game-changer from Davis Technologies, and these are certain to make waves in 2019 and for years to come!
