I think its somewhat temperature dependent. I've got the densos and when it got above 60 here it was knocking like a bitch.

What's causing them to loosen up?

yea t-clamps are the best, I have to tighten mine all the time and it's a pain. If you can get t-clamps do it. I am very soon.

heat and boost pressure

What size t-bolt clamp should I buy to replace the inlet hose clamp?

 

[allstockspeed3]

you gotta take it off and see, i think its 2 1/2 but im not sure.

Yeah I have also come to the realization that my plugs are shit also. Using the stock plugs, and when its cold I i accelerate it knocks like a mofo, but as they warm up there is no more knock other then like a 1ish or maybe 2 if I am lucky

3/2/09 Update. Installed the Denso ITV22's (one step colder) plugs this weekend. Did third and fourth gear WOT run tonight. KR still there, and still hearing the ping. Christian suggested running the 91 octane map and blammed it on fuel quality. I switched to the 91 octane map and will report after 100 miles.

I wonder how he determines possible fuel quality? He has commented on mine, and mentioned it was great. Maybe it's b/c I get no KR at WOT, and hold 20psi .

I took some data logs a couple nights ago, it was only 8 degree's fahrenheit out. And the most I could get the car to knock was a value of 1. Mods are SRI and 3.25" TMIC. The stock tune runs richer than this COBB map and I bet thats why you are knocking so much. Screw tiny ass irrelevant power gains at the expense of reliability. I'll keep the pig rich stock tune just to stay on the safe side.

 

[pwrful4]

It's actually the opposite, it leans the car out and adds more boost to make power. In my case the boost and timing is a little too much.

 

[budgy]

where did I imply the COBB map doesn't run leaner? I said it runs richer stock (and obviously the boost targets are lower)
