While we are on the subject... The discussions seem to focus on the knock sum amount. The first time I looked at an EvoScan log, the first thing I did when I scanned the knock sum column was noted frequency and duration. I haven't seen much discussion on that. I have noticed however, there is a lot of variation in those two factors.

Anyone care to comment? Is a knock sum of 1-2 over a long duration indicative of something different than a sum of 5-7 over .25 of a second?

Where are you guys seeing knock sums? Which colum? Also do you guys see any timing being pulled due to detonation on there?
If you open the file in Excel..go to Column "T" it should be titled Knock Sum. Thats where we are seeing the knock sums.

Who told you that? My knock sums have occasionally reached 3 and maybe a 4 here or there once in a while.

Do you have a wideband? What do your AFR's look like? What fuel (octane) do you run?

From what I've read random low counts here and there can be caused by drivetrain and other noises.

I run 92 octane. And no i don't have a wideband or know what my AFR's look like, though i may take it down to get dyno'd this weekend just to find out.

Spectre, is your car stock? It give me a sign of relief to hear 3-4 is normal. Like "bigd" said, is durration an issue? Generally when you see knock counts is it random one cell at a time, or is it consistant 5 cells long like mine?

So i guess my overall question is, are these knock counts detrimental? Should i worry about them damaging my engine? Is there timing being pulled anywhere? C6C6CH3vo said timing was being pulled, i thought...

My knock counts are just 1 here or there.. and not under WOT.

I'm not sure how much knock is detrimental but you're definately losing power when timing is pulled. You're car is pulling timing but it's a very small amount

Where do you see that? It looked to me like timing was increasing w/ the RPM range pretty linearly.

In the second log it appears that way.. get a good 3rd gear log from 2500-7500

He is not knocking.

1-3 counts in an acceptable threshold for "normal" noise.

The range of knock counts is 0-36.

That tune looks like it is tuned exceptionally well for a mail in flash without being within 3000 miles of your car.

There is no 8* of timing as you can see...

Due to the nature of VENDOR MAP posting limitations and the fact that I personally tuned that Ecutek ECU, I am going to request the logs be removed by a super mod.

I agree, i am very impressed by how accurate you were able to tune this car by a mail-in flash. If anything i think having these posted shows how amazing you can tune based on the coditions. People do this with Dynoflash maps all the time; but whatever.

And you could have just requested that i remove them, i'm all about respect. But if you wouldn't have said anything, nobody would have even known it had anything to do with you.

Nonono. Not mad at you or anything. Just going through the proper channels. Evom makes the rules, so through evom you go to enforce them too.

Actually if anything, I am kind of dissapointed, that #1, you have not credited us with the tuning of this ECU. #2 You seem to be excited to rush out and have Dynoflash retune over my data. You acknowledge an Ecutek tune in your sig, but not your tuner.

Just venting what I am thinking at this moment...

What? Now we can't post logs? This is getting out of hand. I think it's time to start frequenting the Aktivematrix.

<in the near future>
Poor Schmoe: My car is stuttering on acceleration, can anyone help me out?
Vendor: Mods please delete this thread. I tuned that ECU and I want my tune to be protected.

<in the far future>
Poor Schmoe: The fabric on my seat is comming undone, can someone give me some advice?

There are no good maps on Aktivematrix, just junk. Sorry Jack, you're the man, but its true at this very moment. If you are into trading junk maps with no skill, that is where they are and yes, few a vendor maps, mostly DF.

I think you are taking it to the extreme. There is nothing wrong with protecting a vendor's interest when they have spent the time, money and experience developing a skill, just to have it reverse engineered through following the data in an Evoscan log. Another problem I have seen is other vendors stealing maps and "custom tuning" people for 12 hours using the basis of another vendor's map and trying to make someone develop out of it.

The fact of the matter is the opposite of what you describe. It is a great map, tuned to the safe limit with nothing left to miss at peak tq, met all of his requests as to rev limits, launch limits and performance expectations and it is been demonstrated to be a powerful tune without broad cut and paste of ignition timing throughout the load cells.

https://www.evolutionm.net/forums/sh...d.php?t=211142 - , i also still have yet to ammend this post w/ my datalog findings, which will add even more positivity into this write up.

Also at the time of creating this thread i had no idea how to read my datalogs, so i didn't want to go throwing your name out there not knowing if this tune was even safe or not. Now I see it's fine, and i probably would have thrown your name out there if anyone asked.

Also the DynoFlash comment was on these same basis. I made it before i knew anything about how to read logs, and was basing my decision off what other people were saying in this thread in regaurds to my knock counts and timing, which i now again know are fine. I had one day to sign up for the tune, so i figured better safe then sorry; plus we all know a custom tune is better than a mail-in anyway. But i'm not doing the custom tune, i know i'm not pulling timing, and that the knock counts are no biggie, so it's all good.

Oh, and you'll earn your way into my sig after i go to the track and get dyno'd when all comes out good. I didn't want you there with (250 whp dynojet 14.0@99) in my sig, haha.

If anything you should hate me because in your sales rating thing i said "fitment was an issue" when the issue was my install. I wish i could change that...

Oh and, my $.02 is that we should be able to post logs, but not maps. But i guess that's not my decision, now is it.
