Secondary CANBUS systems are slower than primary CAN buses in both Subaru and most modern vehicles. Primary buses (usually 500 kbps to 1 Mbps) handle safety-critical data like engine and ABS, while secondary or “comfort” buses (125 kbps, introduced in 90’s) handle less critical, slow-paced tasks. This puts CANBUS based OEM DCCD Controller (or any substitute with CANBUS) in huge disadvantage to Spiider DCCD Controller that directly reads conditions and responds to control of DCCD electro-mechanical system. . It’s just simple math and physics and and 15 years of results on podiums to prove it 

Important note to highlight to our customers that we did not piggy-back on existing old G-Sensor in your car for Motorsports DCCD Control (although easier and cheaper for us) due to:

• Newer technology sensors have higher sensitivity and larger range
• Advanced new technology has less noise and is more accurate
• We do not know the state of your older OEM sensor so can’t guarantee optimum operation nor can any aftermarket system that does

Our goal is to provide a solution that is easy to install and calibrate and not cut corners in Spiider DCCD Controller to bring you performance on every turn!
