ECMlink critique and maybe help me add a tad more power

[enriquez2000]

Here is a copy of a log I did from a complete stop and letting my awd auto shift on its own points at WOT. The knock blips appear to be shifting areas and are at 0.4 so not too worried about them.

I would like to squeeze a bit more power out. If anyone sees something that may help(still playing with timing a bit). Boost is around 16 to 17 to keep things in control and I am running 25% ethanol. My bottom mafcomp has been tricky as one minute its good and then next i need to add fuel but top end I have on the nose.

Basically looking for critiques

Your MAF looks good.

Your timing map looks a bit wonky to me. I'd try and even the cells out a bit. You're basically at around 12* of advance from 3.5k to redline. Try something more like the map below. If it's too aggressive (and it shouldn't be), just pull a degree here and there where needed, but be sure to even out the cells around wherever you pull timing. Remember, you don't want large gaps or big jumps between cells.

Your fuel table looks like it's decent. I'm assuming you added fuel in some of the cells to combat knock? Honestly, I'd lean out the whole bottom right corner to about 11.0 and pull timing if need be. You'll see much better results getting rid of knock by pulling timing rather than adding fuel, and will probably make more power a bit leaner.

Ya fuel was added for knock... ill try your timing and change all those 10.7 and lower ranges to 11s and pull timing instead.

Do you have a settings file you could shoot over for the timing? Easier than going cell by cell.

Thanks for your help

It's basically a less aggressive 1G timing map. Start with this, and adjust the values to the picture above.

Ok.. i have that one on my laptop. The one i have now was a hybrid with lower rpms 1g and higher evo map.. ill try yours out and see what happens. Ill start with changing my fuel map to 11s and make sure knock doesnt come on(dont see that it should).

Ill be switching to full e85 in the next few weeks and then timing wont be much of an issue and ill be able to target 12s for afr theoretically.

Plug in the map, make a pull, and if the CEL comes on at any point get out of the throttle. Take a pause, pull timing where the knock occurred, rinse, repeat.

You should definitely be over 12* at redline.

I agree.. 12* is not all that impressive. It is nice to wot and not have to pull out though. If i can get it dialed in with a bit more timing ill be happy.

 

[enriquez2000]

here is the log from the changes. I changed fuel table last night and it ran fine with no knock(other than shift points). Timing seems to be too much so Ill need to take some out.

For some reason my maf decided to change a bit as well giving me some tiny knock in the beginning.

 

[enriquez2000]

Im going to try this adjustment.. any opinions?

 

[enriquez2000]

I am stumped as to why with no mafcomp change my readings went wacky.. im way lean when knock comes on. My target is not matching for some reason... ideas?
