PFC Knock setting Q

[Mr_G]

Hi guys,

I had the dash light come up the other day from using Vortex fuel and a spirited drive! Got me kinda concerned, so I now monitor the knock via hand controller when i drive.

Anyhow, I was wondering how do I bring up the knock reading on the PFC hand controller as a Value, ie 20, 34 etc instead of a bar reading??

Is the maximum value that it will hit is 100 knock?

AFAIK you can't change the bar to number's but to read the max knock level hit press UP arrow and it will display in a little box down the bottom, this depends on if you'r in single channel or 8 channel monitoring, same thing to view max values hit for everything else.

After a while you can understand the bar graph just by watching it if you'r passenger, this will give you an idea of what the knock level's are hitting, By seeing how far the bar jumps to the right side.

No,

I've seen knock level's hit upto 130, im not sure how high it goes but you don't want to be seeing thoes numbers anyway.

Oh btw,

I've have not herd anything good about that vortex fuel and detonation is really common when using it !

And don't forget that Their are 3 warning's on the FC: Injector, AFM & Knock so it can be anyone of thoes 3 All flash a differnt sequence when

Injectors reach 98%

AFM Voltages Reaches 5.000

Knock Hits higher than 60

There are 2 types of Vortex, the normal Vortex which is 96 and the not so common Vortex98 which is what you should be using if u go to caltex.

[Mr_G]

Thanks for the info cameron, much appreciated.

I only put the Vortex in, as I had to get somewhere and it was the only thing around! I believe it was probably the 96ron Vortex, but never again! Flat foot brought up the engine warning sign on the dash... BAH!

Anyhow, I regularly use Ultimate, and the occasional optimax. Since the car has been tuned with the Ultimate, I havent actually tried optimax since the tune itself...

Guys, had a look but no luck

can you get the knock bar to show a number or is this the new format PFC that will only show a bar?

Mine's a R32GTR brand new PFC

[Blade]

IM pretty sure its only the bar, ive tried getting a number reading instead....considering how important knock is, why the **** would they have some poxy bar instead of a number,

But in a way its a good thing due to the max reading, and logging/resetting.

In 4th gear i got 65 knock readings at 6700rpm due to my injectors maxxing out, i need to go for a fine tune AGAIN, 3rd time lucky hopefully.

I have had readings of max 128 in 5th gear around 4000rpm.

Time to reduce some more timing, need new injectors

[paulr33]

press down at it shows your the number, but its max figure number

otherwise monitor 2 items at once and it will show you the number

it only shows the bar if you monitor 1 item and its the knock item of course

[Ronin 09]

Thanks Paul / Tim.

Even when monitoring 1 item mine seems to give a bar... :confused:

more playing required.

[paulr33]

i see similar knock levels, its usually only in 5th. im maxing out injectors and afm

ive disabled those warnings so i only get knock warnings, but yeah its usually 5th

and when rpm is under 2000ish or 4th around 3000rpm ish

You should be able to get the number of your knock reading in any monitor zone - 1, 2 ,4 ,or 8.

Just push the right arrow and the will show you the highest number of all the readings. ie peak hold.

I leave mine on the 8 zone readout - peak hold allways to make sure nothing's going wrong.

[cameron]

Up Arrow = Peak hold for highest value

Left Arrow = hold current value

Right Arrow = clear highest value

Down Arrow = Back to normal monitoring.

you should have asked for the benno tour of the H/C

next meet if your there i'll show ya. Ive sussed mine out pretty well.

change it to 4 or 8, and then try

Thanks Ash - just stumbling around in the dark with no glasses on at the moment

[R31Nismoid]

yeah, i was like that a bit.

Its pretty easy once you work it out, and then you wonder why it was soo hard
