thanks. I just really don't see anything in the least bit drastic about making a very modest change on the order of 1-5% and making a test run and then analyzing the scan logs for direction on where...

thanks for all the great information posted in here. I'll spend a good bit of time thinking this all over and track testing and then I'll report back in 3 or 4 weeks if I've figured something out by...

I appreciate your knowledge and every insight and post you've made itt, but I hardly think my intent statement deserves your reply below.





I didn't say I was going to turn of all knock...

don't the 391 gears mess up the actually hp readings? I'm pretty sure they do. You won't read hp as much as you have due to them, iirc.

so, I just analyzed the scan log, and it appears as though the engine used the high octane table for the entire session, even after KR came in. That is interesting. I thought that K detection put it...

Couldn't I just analyze the scan that I have of the driving runs and check out the timing that was used? I believe the high octane table is used until knock is detected and then low octane tables are...

That is not the only qualifier that I have considered in my estimation. Thanks again for an informative post.

thank you for this very informative post. I will take your words and use them to my benefit.

Also, I'm sure that you are aware, your gxp was/is supercharged, and knock is a different beast in such...

I guess you and I have different 'weighting' or 'value' to the words we use. 'Fairly' vs 'certain'.

High octane fuel, stock engine tune, and CAI, headers, how in the world could it be real knock...

lol, why is that 'scary'? I have real time scanning, a/f ratio wideband, history, and I know what to look for and will be able to quickly identify the results and understand whether or not it is...

well no sh!t. I was hoping for a link, since I looked around and searched HPTuners.com for 'updates' and didn't see anything. I emailed the cust. serv. and Jay Payson sent me the appropriate link....

thanks. Maybe this is a good starting point. Yeah I don't have any real sound of knock when I get the retard, so I'll try what you said. I'm fairly certain that it is false.

iirc, you don't need hptuners to destroy vats. I think my 1999 c5 has a connection in the passenger footwell that can override vats with a simple jumper. If I were you, I would research this as a...

I have up to 7* of KR on a stock tune, regardless of octane. I suggest looking into the possibility of it being FALSE. If you decrease the sensitivity and still get it at the same magnitude or...

You mistook the reason for which I started this thread. I don't need advice for whether or not to adjust KS sensitivity, I have already decided that this is what I want to do. I need confirmation on...

Knock Sensor Global Gain table and DECREASE the values?

I have KR coming in at WOT conditions, and I have completely stock 1999 Corvette tables. I think that the KR is FALSE and I just want to...

-oh, I guess my version doesn't have support for my 2006 duramax silverado, huh? I couldn't read the vcm (pcm?). I guess I'll need to update. What is the procedure for that now?

thanks.

^^that seemed to work. I'm back up and running now. What should I do about version 2.1.14 vs 2.2.2 though?

I just found this thread:

http://www.hptuners.com/forum/showthread.php?t=5228&highlight=mpvi

I guess I'll try it out.

I checked and my version is 2.1.14. I don't need an update as bad as I need this version to work on my new laptop. The only reason I'm on this forum asking this question is because my old laptop...

^^ thanks. I just checked and I'm on vcm suite 2.1. So does that mean I need an online update or software exchange?

tia.

Or anything like that?

I bought it probably 3 or 4 years ago, and did the trans tuning that I needed to do and haven't really messed with it since then. I'm getting ready to do some more tuning...

uh, all it takes is a couple seconds worth of WOT donuts and they're toast. :D

Miles, and maybe your exhaust melts into a pile of molten steel.

thanks BBA. You don't suppose that some of my problem might be injesting oil in the intake do you? Lot's of oil gets sucked into these LS motors, mine too.
