Torque Knock PID - may have some progress...

Oddly, since I flashed my car last night my gauge now shows -5.

This has me scratching my head.

Flashed to stock? Very well could be...no one knows how much timing the car actually adds under light throttle?

Or do you mean its -5 all the time??

Damn, quote fail....

Stock to tuned..

 

[FoMoCoSHO]

Never showed less than -4 before

 

[ecoboostsho]

Got it. Well there's nothing in n the equation or PID that would indicate -5 isn't normal so you've got me. It is probably something that can be changed via the tune...

I did also notice a +3 after a wot pedal lift this time to fall in line with the others.

Someone else had reported a -5 somewhere here also. Can't recall who.

Thanks for the quick help and great work testing this out everyone!  Especially finding my mistakes...Doh.  This seems to more accurately represent what I see in FORSCAN so I'm feeling pretty good about it.

I should point out that this IS all based on the assumption that FORSCAN is correct.  I believe that it is but wanted to make sure I pointed that out.

-4 is the max I've seen so far.

Same here. Max -4

 

[ecoboostsho]

Same here -4.0 is all I've seen as well...

Am I remembering correctly that you just got your tuning device then?

 

[FoMoCoSHO]

That is correct

 

[FoMoCoSHO]

I thought the gauge was only set up for -4 also, that's why I was highly confused.

 

[ecoboostsho]

Being that its a signed binary number it could read a max of around -127...that wouldn't be good though.

Welcome to the tuning world on the SHO!!! What's your thoughts? Or I can continue to hold the edge of my seat for, maybe a thread? Maybe a touch of that "perma-grin" lol

Damn, the engine would run backwards lol.

A thread is forthcoming. I'm hoping to gather more data at the track tomorrow. Stay tuned.

Just a note from last night, the new equation seems spot on. The last 2 runs of the night I used Torque to keep an eye on KR. And it was spot on with FORSCan.

Glad to hear it.  Seems to be behaving as expected on my end as well...
