Product Spotlight Thursday

Gen2 Race AIN (Analog Input) specs - versatile inputs that work as Analog0-5v/Temp or Digital (Switched).

Key specs:
0-5V analog range, max 24V tolerant
200kohm input resistance (won't load sensors)
2kHz update rate
Selectable 2.5kohm 5V pullup resistor
Digital mode: 3V threshold for switches/buttons

What to use them for:
Analog sensors (TPS, MAP, temperature, pressure), potentiometers, or slow digital signals like switches and buttons.
What NOT to use them for:
Ethanol sensors, BSD (Bosch Sensor Development) sensors, or SENT protocol sensors - these need PULSE inputs due to their signal type and speed requirements.

Why it matters:
The selectable pullup and dual analog/digital capability means less "wrong input type" headaches. High input resistance means you won't load down sensors and get inaccurate readings.

Tech Tip Tuesday

Switch Decoder lets you run up to 4x switches on a single ECU analog input - saves wiring and inputs on your build.

How it works:
Uses a resistor ladder with 5V pullup. Each switch has a different resistor value, creating unique voltage readings when closed.
Gen1 AIN Temps have built in pull up
Gen2 All AIN have built in selectable pull up

Setup:
Input resistor values for each switch position (shown in Step 2)
Each resistor should be roughly half the value of the previous one
Assign functions to each decoded input (counter, boost switch, clutch switch, etc.)
Choose Active State (Closed/Open) and Latch behavior

Bonus: Switch Decoder values can be used as variables in output conditions - gives you flexibility beyond just direct functions.

Pro Tip: The PDM20 also has Switch Decoder on its analog inputs - handy for keeping your dash panel wiring clean.

Tech Tip Tuesday

User Outputs let you control any output based on runtime conditions - RPM, throttle position, boost, temperature, or any other variable.
This example shows VCT (Variable Cam Timing) control with three conditions:

Condition A: RPM above 1700rpm
Condition B: RPM below 6900rpm
Condition C: Throttle position above 9%

Output function is set to "A and B and C" - meaning all three conditions must be met for VCT to activate.
Why hysteresis matters: Without it, your output would rapidly switch on/off at the threshold point. Hysteresis creates a buffer zone - RPM needs to drop 150rpm below 5000 before VCT turns off, preventing constant cycling.
Pro Tip: Work out your logic (AND/OR/NOT) before setting conditions. Makes the setup way easier.

Tech Tips Tuesday

Setting up radiator fan control in MaxxECU is straightforward once you find the settings and understand hysteresis.

Start temp is when your fan turns on. Hysteresis is how far the temp drops before the fan turns off.

Example: Fan 1 turns on at 86°C, hysteresis set to 2°C means it turns off at 84°C. This prevents the fan constantly cycling on/off.

Running twin fans? Set "Dual Fan Mode" to "both outputs" otherwise they'll stage on/off one at a time instead of running together.

Bonus: MaxxECU has a Fan Override function - gives you manual control via Mdash or a switch. Handy for bleeding cooling systems or track day cool-downs.

What are Pulse Inputs?

Universal configurable inputs for Crank, Cam, VVT, Flex Fuel, Turbo and Wheel Speed sensors. They replace the fixed-function inputs from Gen1.

Key features:
* All pulse inputs accept Hall or VR signals
* Pulse 1 and 2 have selectable supply voltage (5V or 12V) for Hall effect sensors - ideal for crank and cam
* Can be configured as standard digital inputs with selectable pull-up resistors
* 8 pulse inputs total on Gen2 Race

Why it matters:
More flexibility in your wiring. No more "I've run out of speed sensor inputs" or needing adapters because your sensor needs 12V instead of 5V.
Plan your install around what you need, not what the ECU dictates.

Tech Tip Tuesday

From firmware 1.158 onwards, MaxxECU stores base tune files locally on your PC instead of making you download zip files from the website every time.

Files are in: C:\Program Files (x86)\MaxxECU MTune\BaseMaps
Makes grabbing a base tune way faster and easier.

Bonus Content: If you want to quickly copy specific settings between tune files - just right-click the setting tab in the menu, and load from another file. (make sure you have the tab open)

Pro Tip: When doing a firmware update, your ECU backups are saved in Documents\MaxxECU by default if you need to roll back.

PS. Welcome back ☺️ I appreciate you for reading.
