I would imagine the "knock signal" is a fairly raw/unprocessed input from knock sensor. Their is likely a fair amount of digital processing applied to that signal, looking a frequency duration amplitude ect, as the ecu interprets the signal as knock it should act on or background "noise". It is possible that loose nuts/bolts, or exhaust hitting on chassis or similar "mechanical" noise can be falsely interpreted as knock by the ecu. Its possible that this may be your problem, probably worth checking their are no loose bits a pieces hitting or rattling, exhaust , overpipe hitting chassis etc. |

I tried to rescale my MAF. This is the log after my first maf scale
http://www.datazap.me/u/dru670/1st-m...=0&data=1-5-13 and this is another log after I did a second scaling of the MAF. http://www.datazap.me/u/dru670/2nd-m...=0&data=1&hg=1 I was wondering what do you guys think looks better between the first and second Maf scale. I was told it takes a good 3 or more maf scaling to get it right but i'm wondering if it is getting any better or not so far. |

@Dru670 just check that the mean/mode graph is close to 0% and that the curve is smooth. The better the scale the grouping should get tighter.

I've been running this calibration since February including a track day and several canyon runs. I've felt no need to make any more changes to it. Could it benefit from more dialing? Possibly, but I doubt I would get too much improvement in terms of power or knock resistance. During the track day the IAM did drop some, but no lower than .85. I think it's acceptable and don't feel I need a "track tune". Although I vaguely recall reading something about a newly discovered table that controls how the computer makes knock corrections. Would appreciate if someone can point me to some info about that. Other than that I find this calibration quite satisfactory.
http://datazap.me/u/solidone/z6-lean...zoom=2186-2486 For shit's and giggles. Power this tune(save for some minor differences in the fuel tables) is putting down relative to the initial tune for the same set up:

finally was able to get some decent 3rd gear pulls this weekend. Tune feels real good after switching to shell. 40HP difference just from fuel! I did notice IATs shot up after the pull. Should i be worried about that?

I see the computer is pulling up to 4* of timing when you crack the throttle wide open from such 1200rpm. I'm sure that's not a huge problem since it's not often you would drive like that under normal conditions. Also at 3500rpm the ignition advance goes from 16* down to 12* advance. Seems kind of strange it's doing that without any knock correction being logged there. Perhaps it's all normal behavior for a supercharged application. I wouldn't know for sure.

First time trying this, I hope I logged the correct parameters and got enough variance in driving. It was wet out and still traffic on most of the roads, so WOT pulls were basically impossible.
Can anyone tell me if this looks safe/acceptable for e85 tune? http://www.datazap.me/u/pbthomas/log...=1-2-5-9-12-14 |
