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

Oh btw,

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. :(

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...

  • 2 weeks later...

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 :cheers:

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

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.

Thanks Paul / Tim.

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

more playing required.

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

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

change it to 4 or 8, and then try :rofl:

    • When you crank your car, and hit it with a timing light, can you see a steady crank timing?
    • Oh, forgot to add, A few months ago I was getting mixture codes and the car was using crap loads of fuel. You could smell the unburned fuel in the exhaust, it was crazy strong. Economy was over 17.5 l/100 and usually around 19. I smoked the engine and found a leaky CCV hose which I replaced and then I replaced my two pre cat O2 sensors, I also replaced the MAF. This fixed my mixture codes and improved my exonomy but I'm still 14 - 15 l/100 when pottering about town so something is still amiss. Throttle response is much better and it has more pep but I'd like to know why it's still so thirsty (and I'm hoping that whatever it is gives me a bit more poke).    
    • Car is on factory injectors/z32 maf/ q45 throttle body/ z32 ecu with nistune 
    • Hello all, currently finishing up a rb25 swap into my s14. Having issues with starting, car has spark (confirmed by pulling a plug and watching it spark), has fuel(confirmed by checking pulse/voltage at injectors all spark plugs are soaked in fuel). Car cranks over and pops into the exhaust with a heavy fuel smell but no attempt to start or run, I have torn the timing cover off and triple confirmed timing, turned the CAS in multiple spots both directions, attempted to start with coolant temp and maf unplugged, checked my fuel lines and made sure they weren’t backwards, checked voltage at cas/injectors/coilpacks, made sure all the grounds in the harness are connected and added a few grounding straps (1 from chassis to block, 1 from chassis to head, and 1 from chassis to igniter chip) I am getting stumped here. As a last ditch effort I made a full grounding harness tonight that’s going to run from the battery and add an extra ground from the battery onto the coil pack harness/igniter chip/ intake manifold/ Wiring specialties harness ground/ and alternator. I’m hoping maybe the grounding harness will fix it here but posting here to see if anyone has any other ideas on what else I can check. My fuel pressure is unknown right gauge will be here tomorrow.  IMG_3206.mov
    • yeah I was shocked when I checked my spare OEM on and as below that's how they come from Nissan. (side interesting note new NEO gearbox and replacement park lack the brass bush on the tips and its just all alloy) unsure about damage to the box currently back at 1110 to be pulled down/inspected and selector fork replaced as he built it previously and given the never before seen failure on his billet forks he is replacing it under warranty. He said he has used always OEM the keyway tab without issue for years so it could be an unlucky coincidence. I did talk to him about the sharp corners and stress concentration too. Re: hard shifts i got 7+ years out of the OEM one and the fork itself failed not the keyway. so could be bad luck as I said or an age thing + heat cycles in box and during fabrication of billet?
