Hey guys. So this is the final post about my knock sensors issues, after thinking I fixed the issue, of course it came back the next day when I went to drive the car hard again. Turns out it was the tune. I switched to Wengerd, and the difference is unreal. The car is smoother, no more...

Either reposition that clamp or shorten the bolt by 10mm. That should do the trick Shaved off the bolt as much as I could ( pretty much flush with the nut) took it out and data logged. Car ripped and got no positive knock on a 10 min HARD drive. Not getting ahead of myself but it seems that was...

yessir in the process of shortening it as we speak. Hoping that’s my knock issue 🤞

I found one spot that could likely be causing false knock on the headers, you can tell from the picture it’s definitely rubbing on it. Anyone have any remedies and has delt with this? Drivers side right below the ac line

yeah I’ve been emailing Wengerd. Probably going that way next week

Will do 😂 so the drivers side pcv is basically “deleted” so it’s just the breather? I believe the ESS kit came with a plug for the silicone intake where I currently have the catch can going to I’ll have to check the shelf in the garage

Makes sense I’ll be sure to swap those thanks

Why so?

I’m running that breather on the passenger side, catch can on drivers side. 1k miles and 100+ pulls and the catch can hasn’t seen a drop of oil yet👍

Yeah man.. I might have to go that route. I love Lund and they killed it on the N/A tune (not saying what’s going on is there fault) but if I can’t find a mechanical issue within the next few weeks I’ll be trying a different tuner to see if that changes anything. Process of elimination trying to...

They do. I’m gonna try it on the next sunny day I get. I’ll let you know if that makes a difference or not. Thank you for all the replies and ideas by the way👍 much appreciated

That’s a great idea I have not done the re learn procedures. And yes I have a twin disk McLeod rst, I also installed that about a year before the blower

Confirmed it is not.

I’ll be sure to keep that in mind thank you. No misfires, the car runs and feels great even when the sensors go off and it pulls timing, it’s smooth, soon as I let off and go wot again the car pulls hard like it should. The knock always starts during a shift. Sometimes the sensors read knock...

Okay I’ll see if I can add channels and take another log, also will probably order that fuel pump for peace of mind. Plugs are brand new and gapped to .028 (tuner spec) and it’s been an issue since the day I put the blower on the car. If the fuel pressure was dropping, wouldn’t I see that with...

SCT through the obd2 to the laptop and the software is LiveLink gen 2

Agreed I’ll double check the headers. 120mm pulley, id1050x injectors, just a BAP. And it’s tuned by Lund. This issue is so intermittent, the car will run great one day, next day (with the same fuel in the car) it pulls timing usually atleast once when I’m doing a pull through the gears. Also...

Yes. But they were on the car before the blower and I never got any false knock. Only new mods since I was N/A is the blower kit itself

Quick concern for my ESS g3 mustang since this seems like the appropriate thread. long story short my manual ESS car knock sensors go crazy when I shift and of course the car falls on its face. Been running octane booster and logging and it’s better, but still get values of 1-2 here and there...
