Just wondering what this sensor is looking for, heat? pressure? I am looking at purchasing a light weight silencer but have read about motors running to lean due to the sensor??

The EGTS sensor is to measure heat in the muffler so it doesn't reach 800C (1,472F)

I'm more interested in what it does. Cut timing? Ad fuel? Both and more? Does it play any role in the tune prior to reaching critical temperature?

It's designed to keep you going back to the Dealer to spend too much $$$!!!

I know on the Mach 1000s it really was just a safety net if things got too hot, then it would cut timing, add fuel, keep RAVES closed, etc....

I would assume it does the same thing on the etecs.

Mr Gutz is right. Similar to the 1000 SDI, which all your sleds were built on, it tunes down the engine to keep the temps from climbing any further.

The following is when things have gotten out of hand.

Engine speed is limited to 5,500 RPM and RAVE valves are kept closed:
AKA Limp Home Mode

- ECM overheat 85C (185F)
- Engine overheat 100C (212F)
- Muffler overheat 800C (1,472F)
- Oil injection pump wiring shorted to ground or open circuit
- Low voltage in the high voltage DC system. Voltage dropped by 5 V.
- High engine detonation
