The "Invisible" Technology Powering Motorsport

Video Description

Your power distribution module (PDM) can do far more than replace a fuse box, if you know how to use it. 🏎️ Building a fast car?

Enrol today: https://hpcdmy.co/pmu50 Traditional fuse and relay blocks work, but they are blind, fragile and hard to integrate with modern motorsport electronics. In this lesson you will learn how a power distribution module or power management unit such as the Ecumaster PMU16 can replace conventional fuses and relays, simplify your wiring, and give you precise control over every circuit in your car. NOTE: A PDM, PMU and PDU are all the same thing with different names, much like how variable cam control is called something different by each different car manufacturer. Andre walks through a live configuration from HPA’s Toyota 86 race car running a Nissan SR20VE turbo engine, showing how to monitor current draw for components like fuel pumps, diff pumps, fans and paddle shift compressors, then use that data to set sensible current limits, inrush allowances and retry strategies. You will see how the Ecumaster PMU16 integrates cleanly with a MoTeC M150 engine control unit, CAN based keypads from Blink Marine, CAN switch pads on the steering wheel and other devices via Controller Area Network (CAN) messages. You will also learn how to configure analogue and digital inputs, decode CAN messages from an ECU, structure outputs for 15 amp and 25 amp loads, deal with inrush current and inductive loads, and when to use features such as soft start and pulse width modulation for components like electric water pumps and air compressors. Finally, Andre covers logging power management data into a MoTeC dash and telemetry to detect failing components and diagnose issues quickly during an event. If you are building or rewiring a serious street or race car and want reliable power delivery, easier fault finding and cleaner integration with your ECU and dash, this webinar will show you how to get the most out of a modern power distribution module. ------------------------------------ TIME STAMPS: 0:00 - 295 | Basic PDM Configuration 0:17 - PMU16 And Car Overview 0:38 - Viewing Outputs And Current Draw 1:41 - MoTeC Logging Example 2:09 - What A PMU Does 2:57 - Why PMUs Replace Fuses And Relays 4:12 - Electronic Fusing And Retry Logic 6:02 - Anti Stall Example 7:56 - Inputs And Outputs Overview 8:38 - Hardwired Switch Input Setup 10:02 - Pull Ups, Pull Downs And Thresholds 10:46 - Fuel Pressure Sensor Input 11:41 - Limiting Conventional Switched Inputs 12:46 - CAN Switch Pad Explained 13:53 - CAN Message Setup 16:05 - Decoding Switch Inputs 19:05 - Receiving ECU Commands Over CAN 21:18 - PMU Decoding Of MoTeC Messages 22:34 - Bringing In MAP, RPM, Coolant Temperature 23:37 - Thermofan Control Options 24:44 - CAN Keypad Integration 26:16 - Output Ratings And Load Planning 27:14 - Water Pump Current Setup 28:48 - Using Logs To Set Current Limits 29:54 - Retry And Wait Logic 31:06 - Always On Outputs 31:38 - Water Pump Control Function 32:42 - Temperature Based Duty Logic 34:12 - PWM Limitations 35:04 - Fuel Pump Control 35:47 - Sharing High Load Outputs 38:36 - Soft Start Configuration 40:50 - Inrush Current Comparison 41:18 - PMU Logging And Telemetry 48:26 - Q And A 57:54 - Gold Membership Details ------------------------------------ 🏆 Win FREE ECUs, engine components, wiring tools, alignment setups and more.
