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.

    • It's the adhesive holding the ceramic wheel to the shaft the fails on 90% of them.
    • Foreign debris, physical shock, boost leak, could be anything honestly. The danger in taking all the timing out of a tune/hitting the R&R corner is that even if the engine doesn't detonate your turbo is taking a lot of abuse from high EGT. Also, even if nothing goes wrong it is a journal bearing that is spinning at 100k RPM on boost. Eventually it goes through enough cold start/pressure cycles to wear it out.
    • I kinda accidentally saw this, and was interested, but It actually seems to replaces the whole center computer, using the existing screen and buttons. AND it may only be for a G37 and not compatible with a Japanese 370. So its not for me, but someone else may be interested to look into it. Its about $680USD. If I am understanding it right, it basically replaces/installs and android pc that integrates with the existing screen. But I could be wrong. https://gromaudio.com/vline/ The video I first saw was the following, with very little and unclear details.     Even if your not interested in the system, the video on their site was pretty comforting in showing how simple the whole centre comes out
    • hfygrte52 what side you looking for? Do you care what color car it's off? Found a white LH side on here: https://skylinespares.com.au/product/nissan-skyline-r33-coupe-rear-tail-light/   Aussie parts place but will ship to USA. Maybe get it before there's a tarrif on 25yo shit box parts
    • I’m with Shannon’s for all 5 of our cars. Agreed values seem fair, premium price is okay. ($210 ish a month, all comprehensive).  Have claimed once with them for a not at fault claim with another car where my car had no damage. Was one call after the incident and an email after. Deemed not at fault so premium didn’t go up either.    I have called up and spoken with people who are not familiar with certain cars and didn’t agree with me on value or let their personal vehicle preferences effect the call. But called back later and got someone else who was more agreeable.
