Dude, I've posted the table in threads from like a year or two ago (my old screen name, bripab007, became glitchy, so I was forced to create a new one earlier this year). I got the original table off M.net way back when I first joined over there. In fact, the original Excel file I have used to show the raw hex data output from the stock ECU, but it stopped displaying correctly somewhere along the way. I recall the person who posted the table found it on some Japanese site that likely no longer exists.

Anyhow, here's the table that I used to generate the graph (I know the graph was fugly and a little hard to read, but I put it together in the few minutes I had before dinner, so cut me some slack ).

Also went back and re-did the graph in 2D, converted to .PDF and re-uploaded to the previous post

I guess I'm just about as retarded as my timing then. Somehow I've managed never to open that before. But then I lost the map that Rock sent me too...

It's cool, dude. I've seen so many of the same questions asked and the same answers given in the same threads over the years that I could easily be thinking about something I posted over on M.net.

for real this stuff goes around and around everytime we get a noob. Ive never seen those maps before either brian, or i dont remember seeing them. do you have a key for the colors, on the lines, to designate load or, whatever the color indicates.

I found an old thread on this forum where I posted a link to the original Excel file, only it was hosted on a site that no longer exists, so maybe that's why nobody remembers seeing it

Magna, it should be pretty obvious when viewing the chart that the higher the load number, the less timing is advanced by the ECU (e.g. load 15, which is light purple in the key, represent WOT, the highest load registered by the AFM). The ECU also uses the same timing map for some of the loads, that's why several are overlapping and not visible on the graph, but you can clearly see that in the original table.

ok i just wanted to be sure. before i made any assumptions on it.

bripab007

Well what did you think, that the lowest load would be adding the least amount of advance? Guess you didn't notice that the S15 load also matches that of the previous WOT vs. RPM graph?

Just givin' ya a hard time, Magna

geez oh well it isnt as if you dont get much practice. i understand, Its cool. Anyone who can't laugh at himself shouldn't be aloud(alowed) to laugh at others.

bripab007

So, Joe, are you gonna add in a bunch more timing or what? Magna was running as much (slightly more?) boost as you with no intercooler and stock timing!

Yeah and look how that worked out for him :gay:

The problem with tuning for WI is that you're fucked if you run out of water

True, but I'm working on a solution for that too. It's not elegant.

It's hard to tell over the noise from my transmission, but I think I might have heard just a touch of ping this morning. I'm going to advane it a bit more to see if it gets worse.

bripab007

I doubt it was ping since you're running less advance than I am, and I don't have water injection.

You should be able to run a bunch more timing advance.

Well, you were right- I found the source of the "ping" this afternoon. My homebrew heatshield (which is presently in its third iteration) cracked again and was banging against its supporting post. Looks like I've got some more work to do...
