knock knock
Logged this driving home today.
36 counts of knock!?
I don't know how this could be real knock, but I also don't know how this could be phantom knock. I'm not even sure what to do with this. Load is low, throttle is moderate. RPMs (you can't see in this picture) are at 2600. Fuel control is still closed loop. This is in 3rd gear.
You can see 1st and 2nd gear, where there was more throttle, more load (and more RPM), and the same fuel, with a count or two of knock and a slight amount of off-throttle knock coming out of 2nd.
Does anybody else ever see anything like this? I'm at a loss as to how to react.

I didn't know phantom knock could spike like though, I thought it would only account for a few points of knock here and there that weren't real.

No I haven't touched the knock settings at all. There's been so much other stuff to look at I haven't gotten to it yet
I also did not know that phantom knock is known to spike to a ridiculous knock count. I guess it's time to read up on adjusting the knock stuff.

ok change low knock multiplier to 17 and mid to 21 that should fix it.. its very common when we do the swap. or you can go and buy a evo 8 knock sensor and leave the multiplier as is.

Oh is that for a 1g DSM knock sensor? I have a 2g knock sensor which is functionally identical to the evo 8 from my understanding.

and yes they are all microphones but it does matter ..there thresholds are difrent based on motor specs and a butch of math i dont understand.....
if like proff go o the dsmuners.com article on the ecu swap and you will see....

yea but each knock sensor isnt the same... they function the same... but there not the same. thats like saying all mics are the same and you can make album quality music over your iphone and the producer will fix it...

OP, I've actually made high boost passes on the evo 8 ecu. Keep the stock knock settings, trust me, they are fine for your setup.

You need to be a little more careful when putting out "information". If this rumor sticks it could very well start costing people motors. The 1g is vastly different from the 2g and the 2g is different from the USDM evo 8 knock sensor. Just run the correct knock sensor. Its cheap and most need replaced anyhow.
