BUSINESS – PRODUCTS ELECTRONICS MoTeC PDMs
MoTeC has unveiled new additions to its range of Power Distribution Modules (PDMs). These provide electronically- switched power to the various systems in the vehicle and offer an alternative to conventional relays, fuses and circuit breakers. There are several models
available with different outputs and connector options. All are compact, robust and lightweight, and all share the same PDM Manager software, which allows a high level of user configurability. The PDM allows circuits to be enabled either by direct input to the PDM, a CAN-generated input or a user-defined condition. Up to 200 logic operations and functions are possible and can be used to selectively turn off systems. Unnecessary fans, lights and wipers during engine cranking. It is also possible to
automate a shut-down sequence of ancillaries if battery voltage drops. The units simplify wiring and switch requirements and reduce weight, but one of the most significant benefits is the diagnostics ability. A range of PDM
diagnostic information is available via CAN, including over-current errors, current power draw of connected devices, input pin status, voltage at input / output pins, internal PDM temperature and voltages. An impending failure of a motor or an electronic device is usually preceded by a current draw that is higher or lower than normal, so the monitoring of these channels can be very effective for early detection of a circuit problem before it becomes a major issue.

HARDWARE OBP bias valve
OBP Motorsport has recently released a new brake bias valve for use on competition vehicles to regulate the front-to-rear brake pressure. By placing the valve
in line to the rear brakes, more pressure is applied to the front to alter the brake balance. The highest pressure reduction available is 60 per
cent, allowing for a wide range of adjustment to be made to a racecar’s balance. The unit features a lightweight aluminium body with anti- corrosion internals and also includes a pre-set and lock option for rapid adjustment.

UK-based Viper Performance has unveiled several new products in its motorsport range of plumbing solutions. First up is a new selection of push-on fittings to enable NBR-lined braided hoses and 200-series hoses to be fitted to conventional hoses. These are said to be ideal for low pressure oil / air / fuel lines and are available in an anodised red / blue finish or a svelte piano black polished finish for a more discreet look. They come in 120, 45, and 90-degree angles, plus a straight connector and are available in all popular AN sizes from -6 to -12. The second new addition
is a range of reusable oil filter units, designed specifically for competition use. The filters are
completely re-usable, with a washable stainless steel filter element that can be cleaned and re-used up to ten times. The unique feature with this filter element is that it has a 4000gauss magnet providing 50kg of pull that can attract ferrous swarf under 30 microns and remove them from the re-circulating oil. This is also useful for inspection of swarf, which could have potentially catastrophic consequences for an engine. The oil filter housing is made of solid billet aluminium, satin anodised, with a knurled grip for easy handling, making for quick and easy filter removal without the need of tools.
