Hi Everyone!

How are you all? It has been a while since I was last on here due to work and other commitments.

I have a question regarding the knock indicator on the Apexi Power FC. Is it possible to change from the bar graph to the numerical frequency? I usually have 8 gauges showing at any one time and when I press the up arrow a number comes up beside the Knock indicator, which has been as high as 28 but then it seems as though the hand controller intermitently freezes. Do I have a problem, Are the knock readings to high? Please help!

Sincerely

Richard

28 is fine, anything over 60 it fringey, anything over 100 needs to be looked at very soon. If it is always over 100 your in trouble, but generally you only see peaks when putting the motor under load ie going up a steep hill in 5th and then trying to give it the boot!!!

You can mitigate knock by using a trailing throttle ie when your going up the steep hill, slowly ease off on the accelerator ie start at say 100km/h at the bottom and then be doing say 80km/h by the top of the hill. OR you could just select a lower gear and not put the car under load in the first place.

The pfc graph is live,and flickers with the knock reading, the number under it is a peak hold number ie the highest reading experienced is shown. You can reset it to zero on the fly by pressing the right arrow. It also resets every time you turn off the ignition.

I've set my PFC up so it only displays 4 readings (Knock, Water Temp, RPM and Speed). I have the up arrow pressed so it shows the highest readings, plus the numbers are quite large for you to see with the live readouts.

    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
    • So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
