    Possible stage 1 knock???

    Hello I got a little worried this morning when omw to work I thought I heard knocking in my engine, not 100% sure it was but I am tuned for stage one using Cobbs of the shelf 93 octane hwg map. I've done data logs and posted them up others who looked at them said everything seemed fine. Just did another 2 logs the other day and at least from watching Cobbs tunning video everything seemed on the up and up to me was going to post them over the weekend, then this morning omw to work I thought I heard what sounds like knocking. It was after I let off the throttle just before I hit the clutch to change gears, was like a click click click then It would be fine just did it consistently all the way to work all though I didn't notice it till I was almost at work that's when I turned the radio down to listen better. Now the funny thing is it was unusually cold this morning 46 and this is the first time the cars been driven tuned in sub 60 temps.... I drove the car last winter but it wasn't tuned just stock. So any and all info would be appreciated and I was also wondering if I should do a log after work but if this is temp related I'm not sure it will help because it's gonna go back to 70 by the time I leave work (overnight low was the reason for low temp)

    I doubt you would hear engine knock through the cabin. FWIW, knock sounds like someone dumped marbles in your intake.

    Post some of your logs here.

    Perhaps.

    Or a myriad of other possible underhood rattle sources.

    It's not definitively a heatshield that's rattling. However, he asked what the root cause might be, and that's a suggestion of where to start looking.

    Take a vid and see if you can capture the sound. Post up. Other than that, nobody can really tell you what you're hearing, without actually hearing it.

    Was thinking of posting a video but I have the nameless axel back and I wasnt sure how good the sound would be trying to take a video. Thank you EJ as it turns out I jumped the gun a little because I was nervious took it for a quick stroll on my lunch and it deff seems like more of a rattle noise and seeing as how I just put the nameless exhaust on a few weeks ago I am going to start with the heat shield as you stated. Any other ideas on what could be common rattle noises heard from under the engine bay?

    I've read a number of cases where rocks or other debris get trapped between rotor and heat shield. Here's an example:

    That's your car?

    Does the knocking increase with revs?

    I'd take it to a mechanic and have them listen with a stethoscope to the location of the sound.

    That was my next question now as I stated I am running a stage 1 tune will they still warranty this? Or should I put it back to stock and unmarry the ap before I take it in? If I do the second option will the dealer still be able to tell the ecu has been tampered with?
