Did a WOT run today with the wastegate actuator arm disconnected and didn't show any knock. So apparently this is real.See post above, please give me some feedback. I added pressure but the car still thought it was running lean. What is the deal with that? Is that the manifold leaking?

Ok, so I just did the Seafoam treatment and I think that I have an exhaust leak between the head and the exhaust manifold and possibly some cracks in the manifold as well. That may explain the O2 discrepancy, but would that cause some of the knock problems?The fuel pressure is now at 42psi...

It knocks even with the WI activated at 5psi. Timing belt was done ~2 yrs ago because the balance shaft belt snapped and took it out, and a few valves in the process. Head was rebuilt then. I haven't checked the timing but I probably should to be sure.The car doesn't burn oil, it has decent...

It might.But I have 550cc injectors. Theoretically, if I raise my fuel pressure, I will get more timing because of lower IDCs. Am I correct in this thought? I'm up for trying it, though. I was going to up it from 36 to 40 or 43.

Ok, knock sensor replaced but I'm still knocking.I am at a loss for what might be wrong. I'm going to seafoam it tomorrow to see if I can clean everything out. This damn car is pissing me off so much.

Looks like the knock sensor is leaking stuff like crazy. I was under the car tonight and saw it, so I think that'll be next weekend's project.Can I drop the intake support bracket without having to worry about anything else? I'm going to get at it from under the car, it looks like it'll be...

Tom, I had the timing as low as 0 base and there was still knock. I have tried running really rich and running lean as boost comes on, but still nothing. I really believe that it is an octane problem and a knock sensor being old. So I may replace the knock sensor and go from there.

If you're stock with no upgrades at all, I'd look for a boost leak or checking your knock sensor to see if it's bad. There are articles about that in the tech section or if you search for it.

22* is what I see at WOT at higher RPMs. I'm not really shooting for anything, but just trying to rid the car of knock and tune for no/minimal knock. My timing curve looks to be pretty normal.

Generation1JeY, you shouldn't have knock at all if your car is tuned right :) Torque should be 17lb-ft I believe, so that's not very tight at all.coltboostin, I've already tried running REALLY rich to the point that the car sputters and IDCs are too high if I richen it up, and it still knocks.

daren, this is true that on the run last night, I got a large knock sum as I hit 6000rpm. Other runs that I made did not show knock. So random knocking on some runs and not on others probably means that I should check out the sensor, replace it (since it probably has never been replaced), or...

Daren, it sure is real. I put in a few gallons of 100 octane and the problem disappeared.Granted, I probably will get a new knock sensor (after I check for goo), but the 100 octane cured the problem of detonation from high timing. Or at least that is what I'm assuming.It was a cinch to...

I am getting knock at 2800 - 3000rpm when the turbo is spooling. I don't think that the injector is at fault there, but I may indeed be running the base pressure a bit low for WOT runs. I can up it a bit later, but I'd like to get the original problem fixed (knocking when turbo is spooling at...

See this thread for some previous info: http://www.dsmtuners.com/forums/showthread.php?t=243232Ok, so I ran a log with 100 octane gas and methanol and I'm STILL knocking. AFR is 11.x:1 and seeing 21-22deg of timing. I verified that all timing settings are correct.On 93, I'm seeing...

HOLY HELL the car runs like a raped ape on 100 + methanol!!!I will get a log tomorrow on the way to checking my timing to see if the ECU is actually getting the timing that it wants (ie without the pin being grounded) and I will see the REAL timing curve, when octane isn't an issue.
