heat light

I\'ve only ever experienced it on a piston engine, but apart from the sharp metallic rattle coming from the engine there wasn\'t much to tell you it was going on. Always used to happen under heavy load, say in top gear, low revs climbing a hill for example (probably due to the fact I was using spazzy unleaded in an engine with an 11:1 compression ratio!) I\'ve always been lead to believe that it\'ll only take a few good shap pings to goose a rotary, usually by cracking the nearest apex seal.

Did you manage to catch the knock levels on the commander when it happened? What sort of readings are you seeing now?

i am not sure, as talking to a mate and he said put it in 5th at about 30mph and if it is det\'ing (will make a pinging sound) you will here it, it is is then back off straight away and call pip.  

tried this but my car is blowing from the manifold or there abouts and all i can here is that.  hmmmmmmmm..........i dont get this.

what does that pinging noise mean? I get a funny noise when backing off at low speeds around town etc which could be described as pinging. Done it since I have had the car so I just thought it was somthing to do with the exhaust on a rotary...

didnt look at the comander as it was on the floor.  dont often look at it as i have all the my important gauges infront of me, oil temp, oil pres, fuel pres, water temp.  intake would have been low as i had been on the move for quite a while, and my intercooler stays cool :cool.  

am suppose to be speaking to pip in the next couple of days, so will talk to him.  se what he thinks.  my exhaust is blowing a little, perhaps, as some one said above the sensor, picked up on that vibration........i dunno.

Slightly off topic maybe but just wanted to mention it!

My knock light flashed once a couple of weeks ago, I thought it was knock. (but I just read that it was the injectors MAXED out which now makes sense! ) Didnt do it again, so wasnt really bothered about it, although the knock readin have been a little higher than it used to be but nothing dangerous, so carried on driving it normally.  Anyway Saturday night when the bf was driving it, he stuck his foot down and the car took off like its never taken off before and then tried stalling etc. so he backed off truned the boost off and drove home very slowly.. Anyway after some investigating. it turns out that the BOOST box has been knocked  ( its under the steering wheel) and some how been switched from LO boost to HIGH boost.. which the car hasnt been set up for.. DOH! anyway switched it back and doing a full service on it asap to be safe and nothing has been be damanaged and all seems fine now when driving it, so I was lucky! :Laugh. will be keeping an eye on that boost box from now on..

Even if you don\'t look at the commander on the move, it would have held the highest value for you to look at. When I had the light come on, my commander showed that the knock had reached 94, and also that the intake temperature was in the 70\'s due to heatsoak. Therefore, probably detonation - a lesson I\'ve learnt now!
 
Always worth looking at it straight afterwards for that reason.

how do you get to the highest recorded, for a session then?  i know nothing about the comander really.

Press the up arrow and it will show peak readings.
