Just curious, I assume that the 5.9M ecu uses a temp sensor somewhere to detect the incoming air temp and adjusts the fuel curve. I've not bothered looking for it yet. I'm wondering if a quick and dirty way to richen up the bike is hardwire the temp probe for cold conditions, typically bridging a set value resistor across the probe. This trick works well in some cars.

As a side curiousity how many folk have made pipe/intake changes on FI monsters and made no ECU changes with good results live in colder climates?

That trick may work...

The temp and air pressure sensor is mounted behind the headlight.

According to my S4 wiring diagram: 4 wires, Black/Violet is sensor ground, Green/Red is the supply to the Temp Sensor, Brown/Red and Grey/Black are for the Pressure Sensor.

Assuming the Temp Sensor is a Negative Temp Coefficient, an inline resistor would make it run richer.

Let us know how it turns out..... ;D
