no, the issue is still there. I get it from time to time. I try not to drive it at such low rpm lol. Kind of sucks. I still get the cruise light flashing and not being able to change maps as well.

One thing that was not said here is Nissan highly recommends only using “top tier” gasoline in all of their model vehicles. It is crucial what gasoline you use with the ECUTEK and UpRev tunes for our Z’s. Also if you use generic additive low quality gasoline pinging or detonation can and will happen. People getting a ECUTEK or UpRev tune on any Z need to clarify how they want their tune done before hand.

So probably need a little more information on this. Like was it doing this recently after a tune or had it been a lot of miles? What’s your normal driving like, aggressive or mild? Have you actually done some logs and seen just how far out the ignition correction is?

I was starting to get some occurrences as well under part throttle and a decent load like a steady incline and also some occurrences between a 1-2 shift with 7 AT. Most of my driving is pretty mild on the street (I need my license for work and can’t risk being stupid) and it’s been a while since I’ve had a track day. Anyhow mine has cleared up after using some amsoil p1 injector cleaner (which is basically a valve cleaner, other brands have the same stuff) doing a long trip to so cal and some mild pulls where I could, also I added a catch can setup as any oil in the intake system will lower the effective octane rating. This has seemed to clear up the part throttle medium load and has only had minor occurrences over something like the grapevine in summer (steep, high altitude and hot). The 1-2 shift occurrences were cleared up with z1 poly diff kit. Haven’t had an occurrence since however I did all this right before the weather started getting milder (was still summer just not mid summer), so I won’t really know 100% until mid summer again.

In my case with mild driving it can cause more deposits on the backs of the intake valves which can then absorb some fuel like a sponge and make you AF off a little just enough to cause some mild occurrences. Was never bad enough to feel or hear but I guess enough for the sensor to trip.

With this you can listen and see if your car is truly knocking. Forum member here has installed it and it working fine. Now a true safe way to desensitize the knock sensors.

Thanks, I will give it a shot.



Awesome, really appreciate it!

Just want to share that I have similar problems. I validated whether the knock was real with a knock monitor, and hear no audible knock. The problem is known with Ecutek and a new update is coming out soon which gives more possibilities to solve this problem.

Hello,

I have ecutek knock warning at low rpm (1000-2500 rpm). It's mainly on traffic condition (when I released the clutch pedal on 1 st gear) and on highway cruising at 60mph on 6th gear.

It's never happened when engine is cold, only when the engine is warm.

I think I hear the flywheel rattle noise when it's happened.

My current setup is Exedy cluch kit with Exedy light flywheel with oem CSC :( https://www.ctd-germany.com/en/exedy-clutch-kit

Is it possible to have knock warning with light flywheel ?

Is the noise coming from the engine?

The following video is when I released the clutch pedal on 1st gear :
