Knock Reading On Power Fc Hand Controller....

[nsta]

Hey guys, ive jst had my car tuned, and looking at the readings on the hand controller, i know what all but the knock level means.....when i start the car the reading gives me knock = 3...is this bad?

[dezz]

3 is nothing

knock is the engine pinging or detonating etc...

the factory warning is set at 60, which is when the check engine light will flash on the dash...anything up to about 30 is ok. If it starts hitting over 30 you might want to get your tuner to look at the tune...

cheers thanks:)

if you farted next to your knock sensor it would read 3

[Tomek]

yeah. The mic can often pic up vibrations (not in the engine) and register high, keep driving and see if it's a once in a while thing or a common happening, if the later go see your tuner.

i got mine tuned by matty spry.

usually max knock i see is 18.

BUT when i redline it or go a tad over redline it shoots up to 60+...and the warning lite goes off, because he set it that way.

now he said "when u reach the redline or go over it the knock will shoot up. ignore it. its normal"

is THIS true?

The old knock reading mines been up to 133 & gets up to about 60 everyday but had ears on it with a knock detector & we hear nothing so yeah mine might registering my dog box or something else so i wouldnt worry about 3 lol. On start up knock may read a little high.

every time i hit limiter knock reads anywhere from 70 - 120. i try to stay off the limiter. Yes it is normal

holy S@#$ thanks guilt toy.

i was getting really stressed. yea it only happens in 4th gear when the foot is flat to the floor and go near redline.

i will stay away from 7k then

[Guilt-Toy]

go near red line in 4th or actually hit the limiter?

maybe the air is getting too hot and it is detonating a bit.

If your hitting the limiter ignore all knock readings from the limiter. remember stock limiter is 6900rpm.

when i reach limiter man. ahhh, well my limiter is set to 7300. that might be the problem. i will just need to hold back.

[NoFX_Hardcore]

I always get 2-3 knock on startup... Max I've seen is around 35, but I've heard basically more than 50 would be a concern...

[Guilt-Toy]

r33 cruiser, i suggest you drop the limiter back down to 7000rpm.

[r33cruiser]

for sure. matt did it all for me. i didnt want to mess with his tune.

Hey guys, i wanted to set the rev cut to 7500 on mine, currently its at 8000.....how can i set it to 7500 on my hand commander, my tuner told me its really easy and somethingi can set up myself.

Also, i didnt know what it was set at before, and i was driving it hard once, and the car kind of jerked really badly (after going high reves, possible over 8000), was that my rev cut doing this, is it safe to hit rev cut...i guess its better than going over the rev i guess.......

Thanks:)

[NYTSKY]

Yes that was your rev limiter mate. Been driving long?

[nsta]

It was while driving on the motorway, im pretty sure i did past 8000, what id like to know is how to set the power fc hand commander to rev cut at even less funnily enough - 7500

[Beer Baron]

go to settings, then scroll to the last option which is rev. then hit the right arrow so the revs are highlighted then hit down arrow till it's down to what you want. then just hit back and go back to monitor mode or whatever you normally leave it in.

My Mates r33 would contantly register about 80knock on hard driving, the tune was spot on and great. Had a look in his engine bay and his sway bar had a massive dent in it from the intake hitting it, removed it and on full thrash he registered knock of 30. Big change.\

Knock is recorded as any metallic sound as in metal hitting metal, 3 is nothing.

Story pointless just a lil fyi
