S-afc and Knock, Why is my knock rating high? Options

[SiKBOY]

How do you calibrate the knock sensor? As you will probably know all my instructions are in Japanese and I am going off the instructions that are on the apexi.com which are for the SAFC with the buttons not the rotating knob. I am kind of scared to play with it too much cuz I dont want to mess up my car. I already thought I messed it up when it was nearly stalling.... I set the "PRESSURE" "IN and OUT" to 2 instead of 3.

ok....about knock is normal that you don't read nothing on the channel monitor, cause it says just when the knock goes over the values you set in Settings->Knk set menu. there you have to insert a value for idle and one at about 3k RPMs.
Anyway....in sensor check display you read the actual knocking value.
Tell me this: you said that at idle your knk is about 20....mine too when the engine is cold....
Can you say me your idle knocking value after at least 30 minutes of engine run?

Thx

I havent taken the car out on a run yet. Ive only started it up to see that it actually works, thats how I got the cold Idle knock reading from the check sensor display. but I'll get back to you when I do take it out for a run

How do you know what values to set at idle and what values you set at 3k?

[edo17982]

I suggest you this: let the engine become at normal operating temperature, then go on the settings ->knk set page
Now just rev at about the RPM level disdlayed at point 1 and hit the center button to the right (or bottom, I don't remember). You'll see the value you memorized for that RPM level.
Now do the same for the RPM level at point 2.
Now If you go on Monitor -> 1(2,3or4) channel -> knk you'll see if the knk you set for that RPMs is higher than what you set.
Hope you understand, I'm italian and my english isn't perfect!
Any question feel free to ask

another thing....In & out pressure is 01 and 01 not 3.....we just have 1 pressure sensor signal (in) and 1 wire to the ECU (out)

Wait, edo are you sure about the pressure thing? I have mine set at pr in 03 and out 03. Remeber you can download the instructions onine in english at www.apexi.com.

[edo17982]

I just was remembering wrong, I set 3, sorry to all!!

[HyperDeathKill]

Yea, anyway your english is pretty good, don't worry about it. SikBOY if you still need help you can hit me up on AIM at HyperDeathKill.

Edo, I have those numbers that you were after. After about half an hour of just cruising around the knock figures that I got from the test sensor mode are between 50-80.

In the knock setting mode I've got a reading of:

53@ 1300 RPMS
126@ 3200RPMS

I didnt really get a chance to set it though. I just highlighted it but it didnt give me any option to put in numbers or anything so I dunno how it chose those numbers. It just did it automatically. I am guessing that that is supposed to happen.

Hyper, I love your " I want to upgrade my hamburger" topic. Its a CLASSIC!
