Timing un-retard... How far can we go?
#21
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 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.

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.

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...
