Getting some sweet knock in the VR-4

[Alpine TSi]

As the title states, I am having problems with knock in my GVR-4.

Car: 1992 Mitsubishi Galant VR-4

Mods: EGR Removal, Custom EPROM chip by LightningGSX(stutterbox, enhanced closed loop, knock display, etc...)

Other Info: 157K miles, only 92 octane from BP is ever put in it. NGK BPR6ES gapped at .030, no boost gauge(I hope I am running whatever stock would still be), factory BCS installed, most free mods done.


Here is the deal, after doing some logs I am finding out that I am good until about 4K RPM, I get a nice stock feeling pull from it, and then the knock starts to go up. On a run where I started logging at 3600 RPM I was getting 29 degrees of timing, 29% injector duty cycle, and .91 volts on o2. By 4000 RPM I was now at 16 degrees of timing, 61% IDC, and the same o2 but with 6 counts of knock. This is where it all starts. Now by 5000 RPM I am at 11 degrees of timing, 75% IDC, still .91 o2 and 22 counts of knock. 6000 RPM I have 11 degrees of timing, 88% IDC, once again .91 o2, and now 36 counts of knock. I pulled out of this run at 6600 RPM with 10 degrees of timing, 91% IDC, .91 o2 and 42 counts of knock.

This is pretty much how all of my logs look for just about any gear. I only get real power for about 600-900 RPM then it starts knocking and I get no timing.

Here are my questions:

Why the hell am I knocking on what I think should be stock boost?
What are my options?
Is it possible that by looking at this info that I am encountering phantom knock?


The car is practically completely stock. I haven't done a boost leak test, nor a compression test since I got it. It still has the stock 450's in it. I do have an old 5 knob AFC mounted in it and within two days should have it wired up. I have a boost gauge and MBC that should be going in shortly thereafter. I haven't checked the plugs since I bought it 4-5 months ago, and I was thinking about changing to BPR7ES's with a .028 gap. I also have some RC 500cc injectors laying around I get get cleaned and tested and throw those in if they would help.

Any other ideas?

Thanks in advance!!!
