Yes. We think spending thousands on equipment, wiring, and 10s or 100s of hours in custom wiring to eliminate some relays is unnecessary in most cases. Making the other benefits of a PDM (keypad control, configurability, flexibility, CAN-interoperability) simple is our most important goal.

Simply put, properly installed relays have been proven to be reliable and solid-state relays are becoming available for those that want no moving parts in their electronic systems.

Probably not. We’ve seen countless over-budget, behind schedule, and unreliable builds because people under-estimate the effort and skill involved in rewiring a car from scratch.

Most of our sports car customers keep the essential factory wiring in the car, then use the MicroPDM to power their accessories.

Additionally, we’ve found many sports cars are factory-engineered with low-side switching of fuel pumps, head lights, and wiper relays, etc. Our low-side modules can naturally integrate with those factory circuits without having to gut everything and start from scratch.

We’ve seen our customers do all kinds of things:

• Turn on cooling fans when temps get too hot.

• Control dash through keypad and steering wheel buttons.

• ECU control of fuel pump with keypad manual override.

• Send pit speed or fuel reset command to ECU from keypad (and steering wheel).

• Log data to see which drivers flash the headlights the most, use the radio the most, turn on the pit-speed limit at the right time, etc.

• Create advanced headlight flash logic in ECU.

That’s completely up to you and your application. You can always mix and match, one low and one high for ultimate flexibility. Or you can use a relay to switch a single output from high-side to low-side.

The majority of customers select high-side PDM modules.

Not exactly. You can use the MicroPDM as a CAN-controlled device without a keypad. For example, an IMSA team uses our MicroPDM and controls it exclusively through the MoTeC system in the car.

Absolutely, as long as it is one of our supported keypads. See the User Guide for the most up-to-date list.

Unlike some other vendors, we don’t lock you in to buying keypads from us at inflated prices.

Please submit our dealer application form and a representative will contact you.

There is no app. Nothing to install, update, break.

All configuration is done with the keypad summarized in our Quick Reference Guide and fully documented in our User Guide.

You can also configure the device over CAN. This is used by “power users” and those that need to configure multiple PDMs.
