High-voltage and low-voltage input circuits work with any trigger source from a 5V sensor to a 350V HEI distributor, while dual 5V\/12V outputs let the BTA feed ECU's and pulse-driven accessories, not just tachometers. The input is schmitt-triggered and software-filtered, allowing a simple resistor to filter it for systems with very high amplitude “ring” like HEI, while also allowing it to see very low analog voltages, like wraps on spark-plug wires.  Ratios for 5, 7, 9 and 10 give it flexibility to work with fixed-magnet alternators on motorcycles, outboards, and other small engines, avoiding the necessity to tap their often-messy ignition systems.

Instead of a voltage-doubler like most of WM's competitors, the BTAC2 uses an 80 ohm coil to mimic the action of a larger spark coil, providing an identical “kick” of high-voltage to trigger vintage tachos which won't trip reliably at 12 volts. Better, because it's an actual coil and not a doubler, it will trip tachos the competition can't, like old VW's that need a spike of negative voltage. Internally, it uses a honking 2-amp 400V mosFET to drive the coil, so it won't blow up when connected to an active-low ECU output like some other designs.

Get full window functionality with 4 button-pushes and zero engine configuration. Or get simple on-off function with two pushes. The RSA uses a patented technique to adapt itself to whatever coil or sensor you hook it to, safely in the garage using any tachometer for calibration. Just program the setpoints at half the RPM you actually want, keeping your engine safe instead of trying to push buttons while redlining down the street. The RSA automatically learns the signal rate for your engine and does the rest. The RSAv10 has been redesigned to use up to 7 external relays instead of the single onboard relay in the original, and a 30\/40A 5-pin type is included in the kit along with a pigtail socket. The input is also selectable to accommodate high speed digital and sine signals from crank and VSS sensors, up to an astonishing 480,000 pulses per minute (4 times the maximum of the original RSAv00). It has 8-pulse averaging for signal stability, and since it can use almost any relay you choose, using it NC to cut out the A\/C at high RPM is no more complicated than using it NO to cut in a solenoid. Or cut in an extra fuel pump, or hook it to the VSS and cut out the radiator fan above 70 mph (although you may need to program that on the road).

It also provides the pullup resistor most Hall sensors require, with no need for extra components or wiring. The 6-pin hookup is designed to allow seamless \"pass through\" when interfacing to a Hall sensor's 3-wire harness, with an extra ground wire and signal wire on each side. If you don't need the pullup, such as using it to power a model FPMS temperature sensor, it can be disabled simply by throwing a switch. The unit is temperature rated to 225F and epoxy sealed to live in an engine box, and can be made completely weatherproof (IP65) by sealing the adjustment pot and DIP's with a dab of RTV.

The CCA takes advantage of that by simply multiplying the signal, accelerating the COP signal into a 4-cylinder pulse train and the DIS into an 8-cylinder. There's zero configuration, just set the new tacho to match and you're done! Better still, the CCA has software filtering optimized for the slow firing and lengthy “coil ring” of COP and DIS coils, so no external filter is ever needed.
