Need a little help...

Ok here's my question...in my picture these are the cells that I edited to get rid of my knock...my question is how to I make is so everything around it flows smoothly...

Well the rule to follow is as load increase timing decrease, and as rpm increases so does timing. And for transition purposes try not to have a jump of more than 3 degrees from cell to cell.
There was a thread around here somewhere that had a nice map smoothing tool that you can use.

Yes, 3 is fine considering your scaling.

You can also use bigmaps with much more data and get a better tune.

ok so i tried the map smoothing...but all it did was change those values back to what they originally were...creating the same knock...what method are people using to tune properly...it's prob right in front of me i must just be missing it...

Unless your on a really old version of ecuflash you can simply use the graphing feature and smooth then yourself

Just stick the cursor somewhere on the mouse and use + and - to change values looking at the graph and you'll get a visual experience of how to smooth it out

ok...maybe it's not the smoothing feature I'm looking for...what I'm looking to do is eliminate all knock...and if possible add timing in spool up to create more power...how would I go about doing this? Just add timing in spool up after running logs with no knock...and work all the cells around what I log? Or is there a shortcut I can take after changing certain cells to "match" what's around it...

Change the timing to suit the path your car is following. Then smooth the map out with graphing like i mentioned so it goes beyond the point, or under, the timing is relative to the setting you put into it. Making sense?

What exactly does this part mean? I'm getting the rest now...

When you use graphing it will make sense. The changes you make are either going to make a bump or a dip in the map just smooth the curve so it makes sense, make it flow .

Ok I see...ok so one more question...when I'm logging will my car only run along the same path on my timing map no matter what gear? Or will it be different due to higher gears causing higher loads?

Of course it will be different if the load changes lol

That's why when we tune and make changes we smooth out the map with each iteration. Trust me its not that hard you'll get a feel for this sort of thing especially the shape of the timing slope when graphing it out will make a lot more sense than a table of numbers, me being a very visual type of person.

Ok yes...im seeing the graph now...and working on it now...so basically it should slope down smoothly with no big "points" in between cells...I think I got it...

Well you want it to slope to the point you just changed. So if your adding timing for example your making the hill above it and below it higher so it keeps a shape but works to the same point smoothly.

Timing maps tend to look very organic with smooth curves in them you'll see.

Ok I'll keep looking at it and working with it...thanks for the help...make more sense now...especially with the graph...better than just a bunch of numbers..
