PLEASE HELP KR readings no solutions

[stripSHO]

No I was driving in D just normal highway driving on my commute to work. 60mph cruise set approx 1500rmp. I never really use sport mode and don’t intentionally lug my engine. It just happens when I go up decent climbs as I live in a pretty hilly area. Once it downshifts to 5th the knock goes away. This is ALL on stock tune. ….. with that being said once I load a tune I’m finding that from a 1st gear start lay into it to the floor and she takes off like a rocket. 1st and 2nd gear perfect lots of power. Then BAM it hits 3rd gear and I hear this very quick clacking noise for literally 1/4 of a second and the KR spikes to 7.5 and that’s all she wrote. Makes it totally worthless if I need to run on the Highway against anyone or pass someone and I also got severe cylinder 3 misfires the last time I stepped on it to pass someone at 55. I immediately returned back to stock and haven’t had a misfire since. ‍‍‍‍ Matt’s been a great help but we know tunes will amplify whatever issues we are having.

Ok cool just had to make sure. Yeah definitely need to take a look at the plugs, double check the gap, check compression, etc. I'd focus on the misfires and clacking sounds and 7.5 KR, and not worry so much about the stock tune getting a little knocky when lugging itself.

HMU if you want a fresh set of eyes on your logs. I'm no diagnostic expert but I do sometimes find abnormalities that others overlooked.

I greatly appreciate this. My plugs are clean I just pulled them a week ago and made sure they are all .026 gap but this weekend I’ll pull them all again and take a pic and upload it here. I’m also gonna swap the 3 coil to the front row and see what happens. Then load the tune back on. I’m at the point I might just have to dump dolllaaazzzz at a new front mount, 6 coils and 6 injectors. Luckily I can do the labor myself

Ok so STOCK TUNE the car runs great and the only time I get high knock readings is when I’m going up hills steep enough that the boost goes above 6psi. See video. If the car downshifts to 5th and the motor does the work unassisted by boost there’s no KR. On flat ground I can step on it till boost hit 12psi and stay in it and no KR readings ‍‍ STUPID HILLS. So in my mind I’m thinking it’s fuel/air related as boost goes up and load going up a hill requires more fuel and more air I feel as though maybe the coils could be weak yet not failing? But then when I go WOT it has power and accels smooth and no knock. I’ve searched the whole engine bay for loose items and when this is happening there’s not a lot of torque it literally just happens under 6+ psi boost and the higher the boost the higher the knock. Turbos have 50k on them. No oil leaking or anything. And I repeat under heavy throttle high boost high rpms no knock. Plugs are new and gapped properly. Any suggestions??

just some dumb stuff check to see if the WG acuater rods are still attached to the turbos as the E clips have be know to fall off. You have changed each primary O2s?

I thought I tried bouncing some weird ideas off you. That is if none of these other really good ideas work.
What are your temperatures like during throttle application?
If you can borrow up borescope, have a look and check out how gummed up your intake valves are. Be sure to unplug the throttle motor if you do this. If some valves or intake ports are more plugged than others by build up, you could have uneven airflow. The oxygen sensors will try and compensate and might lean out one cylinder too much. The other possibility is carbon buildup.
To end up with real knock you're either running too lean, too hot (temperature, compression or a hotspot from a bad plug) or too much timing.
Everything else should be considered false knock. Bad wires, bad knock sensors or loose / rubbing parts.

All these cars experience KR in stock form. I seriously suggest you forget about trying to solve knock activity at 1500 rpm and high load because I bet at least 1/2 the SHOs on the road would be doing the same thing in that situation. The stock tune is knocky in some spots.

Now, the GH tune is also very well documented to be knocky, especially around shifts. Some people have no problem whatsoever, and for others the KR is intolerable. Welcome to the club! Do some digging around this forum and you'll find a lot of guys have to add some e85 to their tank to keep the knock under control with GH, but have no knock with other tunes on the same car. If it weren't for the misfiring I'd tell you your only problem is your tune. But, you ARE misfiring, so worry about that first.

My 2cents:
Gearhead tune since about 40,000 miles, now 92,000 miles. Super Shell 93 or Mobil 93. Mods in my signature. NEVER, NOT ONCE have I heard a ping. I live in a hilly area where I climb and descend every time I drive.
A ping would cause me to take immediate action, if I ever heard one.

Any progress this?

 

[SHOamBroke]

Very little progress. I loaded the tune back on. I’m running 92oct and 2 gals e85. Fuel rating is -0.96 and doesn’t move. Someone mentioned they had knock from their air raid box rattling against the hot side plastic pipes. So I put the stock filter back in. No change. Went back to the Air raid CAI. I double checked all wire harnesses and made sure they were all supported and I secured a few. Not much change however the same hills I was getting +4-6 Kr is now lowered to max of +3. So maybe something helped a bit?
Fairly new development though…… I drive the car about 20 miles on cruise tonight and under normal driving I don’t get any knock. Mayyyybe 1.5 max. But I got to a part where the lnes widened up to 2 lanes and I floored it and she was spitting and sputtering and chugging it was rough as **** I stayed in it till I was over 100 mph trying to trigger a CEL to indicate a starting point as I’ve moved coils around but nothing. While it was misfiring the KR went to +6. Slowed down to 50mph. Did another wot and I noticed that whenever it downshifts and rpms go up there’s a huge boost spike to nearly 20psi and then the KR hits 6+. After I did that 2 times itvwas like it cleared up on me and every time I did it again she revved smooth and pulled me into my seat and rocketed to 100mph like nothing and KR never went past 1.5.

THIS IS DRIVING ME CRAZY it’s so inconsistent. I’m having surgery next week so I don’t have the $$ to shotgun parts at it. I guess maybe try a pass side motor mount and maybe try stock trans mounts again? Read another thread that people have had KR post AD mounts. I actually installed my mounts way before I even got my tuner so I don’t know if it was having KR before that. Anyone good at reading logs? Matt is outta ideas and so am I.

Yup and both rods are tight and no play And yes both primary’s are new and new knock sensors.

Well here’s the update. I loaded the GH tune back on, I was still getting sputters and hesitations like misfires but not real hard and not enough to throw a code. I could only use aboit 75% throttle before misfires and knock would go up. After thinking about how the knock would go up in accordance to my boost going up I knew it was related to either fuel or air and I was convinced that the coils may not have failed but they were weak. I doubles checked all my ignition wiring to make sure nothing was chaffing and no exhaust banging. All was good. Ordered up a set of MSD coils and I was ear to ear smiles. No hesitation and no misfires and no matter how hard I drove it max KR was .75 I finally feel like after 2 months of racking my brain this car has woken up and the fun is just starting.

Good stuff! I’m glad you found the issue! That’s the worst when when your chasing down KR like that.

I received a Ford reman and have had nothing but problems with knock and other issues. Chasing knock counts and having to drive a certain way to get the AOR back to -.96 each day has been driving me crazy. 20k miles in I found I was pushing water, Head gasket failed (sorta) removing the head and looking at the head bolts shown the failure location was due to a poor install. The area in question had a head bolt that shown it had not been fully install as matching up to the other bolts. When cleaning the threads in the hole it had a stopping point and had to be worked on to go deeper. While out, ported the heads and cleaned them up and added ARP's to lock them down. Still had knock... fast forward. 5k later I found the true problem. Bad rod bearings... while I use some great oil, I feel this only made the problem take longer to show up. Bad rod bearings and they took out the crank. Just replaced it with a young junk yard motor, replaced all the timing stuff, oil pump, water pump, and all timing related parts including phasers and solenoids. Fresh start - on stock tune it's never shown knock. Will be rebuilding the other with updated parts and slide it back in when the time is right to put down some real numbers
