Quote from: leefitz;672042how do you go about reading the knock sensor?

Quote from: turbotoaster;672047if you have a power fc it will show it on the hand commander

If you have a hand commander it will show you the readings. If you don\'t, but still have the PFC, the red "HEAT" light on the dash will flash 3 times in quick succession to show that the sensor is picking up the sound of knock. However, like with the water temperature gauge, by the time you know about it the damage is already done!

When the front of my engine disintegrated, the knock readings where 17 max so it cant be relied on.

My knock value is mostly in the 20-50 range, but sometimes goes up to 100+ when second turbo kicks in.

I had a knock one time of 160 when on idle and turning on the lights (the popups)  ;)

is the car mapped? id be concerned if it goes over 100 on the second turbo as thats where peak torque is

AndersE

Yes it\'s mapped by garabedian racing (G-R.se) in sweden (check his rx7 on youtube 899Hp fd).

It happens just sometimes, just in the transition between turbo 1 and 2.

 :Yawn So would you be more concerned for me then, mine is disconnected and is not used... \'highly modded over 400?\' :rolleyes:

dont be a plonker!!

i asked if his car was mapped, if it was and he was always getting over 100 then we can assume its just a bad sensor, if not then its worth looking into.

You should never ignore a sensor until you know its defo reading wrong, else theres no point in it being there.

Im running on a basemap and if i got over 100 while in boost i wouldnt be continuing to floor it....would you?

Sorry I forgot you are the 200 mph guy.......  on a budget!

Apoligizes....

whats that meant to mean, just because i have a budget to work to suddenly my opinion is worth nothing, the guy after i asked said that it had been mapped, so then he will be fine to ignore it.

I shall make the assumption that you are genuinely apologising because i cannot see for one reason why just because you ignore the knock sensor its fine for everyone else to...unless its already mapped like i previously asked

to be fair, if he regularly saw 100+ as the 2nd turbo was kicking in, and it was genuine knock, he\'d prob be in the wanted section looking for a new engine
