Torque Knock PID - may have some progress...

[scap99]

Playing with E-85 has kept me pretty entertained.

As soon as the cutout comes back it's on!

I'm also considering upgrading the turbos at the same time, overlapping labor and all that.

I'm also considered that doing all that plus turbos may cause a rod to overlap into my block, so IDK.

I sure hope you don't poke any holes in your block.

I'd leave the turbos alone for now... after all you haven't even experienced a tune. ;D

I am tuning scap99's truck...we are getting some great power out of it for such a heavy platform....we will continue to push forward with the E content and would love to see some of you guys in our shop for some tuning...

He will run 12's with no problem next time out at the track and I am excited to see what the transverse platform is capable of...

I know I've shocked a few people with it, both at the track and on the highway.

Found some knock.

How I'm getting it at 35% ish I don't know.... only thing I  can think of is the fuel just won't mix right.

 

[wasinger3000]

..... I really should just get a meth kit.

You'll find out what the transverse is all about the first week of August as soon as I get back in town.

Looking forward to checking y'all out.

2% is nothing. I know you want 0, mine does that either heat soaked or when it's really stinking hot out. I'm running 94.

Its not the fuel, mine does it too. I think its happening under heavy throttle, coupled with an abrupt lift. I need to redo my data logging parameters and try to pin it down. Its not dangerous at all for us but could be for the guys running straight gas. Consider only A6's motor came apart under that same circumstance. It also explains why some of us have noticed throttle response going away under spirited heavy off-on conditions.....the car is seeing knock and goes into self preservation mode.

Well that's good to know. I might have to  ease off the throttle after a wot run.

One thing I've been thinking about is this, if I have a meth kit and if at some point I floor it to pass and the meth doesn't spray because of a mechanical failure will the car be able to pull enough timing to protect it? to Or will I be picking parts up off the road....  that's the one thing that keeps me away from meth right now.

It depends on how the tune is setup. I set mine up to take advantage of meth, but not to be dependent on the meth. This would be a question for your tuner...I don't ever want to have to worry about a customer blowing their motor because their meth kit failed...

 

[panther427]

That's the reason I plan to run water meth not straight meth.  A tune will not be depending on the extra fuel as much as just the intake cooling effect.

Again, it depends on the way your tune is setup...I recommend 100% meth, but I don't setup the tune to depend on it, ONLY to take advantage of it...

I was able to verify this today, it is knocking after wot abrupt lifts. Turned corner, downshift to 1st let off and saw 1.5 on the gauge.

Curious, you are not tuned correct? Although 1.5 really isn't anything the car can't handle. Need more data, was this just after a heat soak? What were your other readings (IATs coolant temp).

At least it's protecting it's self. I'll have to take a look at mine and see if I have the same issue.

I am untuned conditions were low 70's no heat soak. Consider that A6's car blew up on a lift condition. His car was tuned. Also consider that I am at 100 octane and seeing knock, so what is going on with the cars with much less knock resistant 93.

It is starting to make sense why the throttle disappears during spirited on off driving.

 

[FoMoCoSHO]

Maybe one or more of our esteemed tuning vendors will chime in here.

 

[Leading Edge Tuning]

As sensitive as the knock sensors are on these motors, it is a fairly common occurrence to see knock when you let off the throttle. There seems to be noise created from the TB closing.

As far as power going away in repeated runs, the tuning has safe guards based on IAT, coolant temp, cat temp, valve temp, flange temp, EGO temp...well, you get the idea...

Only time I get timing pulled is when easing into full throttle from a roll(still quick throttle , just not punched to floor)...any foot to the floor action gets 0's....

Interesting. Mine adds.
