Please take a look at this log and tell me if you all think its tuned safely enough. I'm just paranoid about it I guess lol some parts seem a little lean to me.

its a 3rd gear pull. the car is tuned for 23lbs on pump gas. but here I'm only running about 18-19 . because when it gets colder it will get leaner.

log is at the bottom of the page:

umm where's the log? Now thats funny, right at the same time...

 

it wouldnt let me upload it to here. So I made a link to where it is

 

I honestly think it looks ok. Its giving some knock, but AFR's in the low to mid 12's have always done me the right way. I have never experienced any problems. But based on how paranoid you are I would richen it up a little bit. Wont hurt anything.

Hope some other people on here can give you some more advice.

 

is the knock sensor voltage the same thing as a knocksum???

thanks for the help

 

no, knock sum gives you the total number of knocks at any given point... Always use this method over voltage...

I would fatten it up a little bit to be on the safe side... Overall the tune looks good...

Cheers-

to add fuel do you just go to the rpm and load that you want more fuel at and add some???

I'm kinda a newbie lol. also is there a way to get a knocksum. not just the knock sensor voltage???

 

Its a little more involved than that. I would have someone who knows how to do it, fatten it up. Its not tha hard. Pretty much adjust the load cells with higher AFR's.

But like I said, I wouldnt try it myself unless you have a good idea already of how to do it.

 

ok cool. thanks for ya'lls help

 

What is your knock threshold voltage set at on the AEM? That is the point that the EMS actually believes there is true knock and then pulls timing and or adds fuel.

I only seen a few spots of what I would probably think is true knock those being the voltage around and at 3volts

Your A/F's dont look too too lean mostly in the high 11's , probably higher than what most consider safe , but each car is different cant base it off of what someone else runs

Bottom line is if there is very little to no knock happening dont worry about the A/F's it must be working with your setup. Now if you get the same knock events in the same location of a pull everytime the obviously a small adjustment needs to be made at that point.

keep logging knock and all the other goodness you got there and it will tell you what you need

 

Just an example as to how each car is different:

I have a buddy has an Evo , same turbo kit / turbo / injectors / stock motor same as me/ Same tuner in Dave Buschur.

He gets a tune for 93/meth , I install meth same setup as him.

He lets me load his tune , now I have been to the 1/4mile track several times with my buschur pump gas map and would trap consistent 122 mph boosting around 24 psi.

I load his meth tune with me spraying meth and do some logs on the street , all everything looks good very little knock events and now I got my boost up to 27-28psi on his tune

I go to the track first pass car go's 120 mph , log is at 27 mph, ok maybe something weird , I make a second pass with a small adjustment on boost , again only 120 mph @ 28 psi on the log , so now its like WTF!

I say the hell with the meth pull the fuse , load my pump map turn the boost down to 24 psi and immediatly trap 122 mph for the next 3 passes right back to where I was.

Sorry for the small rant just wanted to point out how differnent things on other cars can be even if they are virtually the same setup and the same tuner, some works for others and dont for another

 

it looks fine to me..you get a hit here & there of det., but nothing to be concerned of IMO.

is your aem set-up to kilometers for speed? if your running a ait sensor, if the file is set-up correctly, this shouldnt be a concern, as the aem can adjust fueling for inlet air temp differences.

for a 35r, why does your boost drop down to 17/18 psi? being you have a 2.3, your boost looks very laggy....i have seen 37r's with better spool-up....not knocking you, just think you need to look into your boost set-up.

i think you need to change your map filter to something like 6 or 8 to get rid of the jagged boost signal.

 

nah its cool man I know your not hatin on me. say your honest opinions. sometimes thats the only thing that can help. What do you mean "map filter" 6 or 8. Im not that experienced with the EMS.

 

open your cal file iwthin aem pro, go to

set/sensors/manifold pressure sensor / options, about mid way down is your map filter value. this filter will help minimize the oscillations that the sensors see's due to a number of reasons...this wont make your boost signal lazy; with a 6 or 8...but if you made it 20, it would.

this filter helps reduce the likelyhood of multiple cells being used when running through the revs, maybe adding fuel, leaning out or addidnr or removing timing unnecessarily.

 

Okay I'll give this a try
