Well in that post hes using a wideband o2 to get those readings so im confused by what your saying. But ok small changes sound better to me anyway.

 

This is literally the thread that i am referring too. So now Im REALLY confused as to what your saying.

 

i dont know about doing it that way, i dont recommend it. just do it the standard way for now, unless someone else chimes in here and says otherwise.

 

uh...... let me read what it says hold on.

 

ok i see it. its a calculation on how to get the number you want for the a/f. it has nothing to do with evoscan. he wants you to create a excel that auto does the calculation. after you calculate it then you edit the cell on the map trace..

 

Ok so this is what I did. I highlighted the cells that i basically hit (shown on the map tracer) and then lowered (richened) them by 0.2 and then the surrounding cells i decremented by 0.1 to try and smooth things a little bit. Did I go about this right? You can see what was changed in the fuel table by the outlined cells.

 

if i were you, id adjust the cells by .3 and then do another pull and compare the old to new wideband reading and figure it out that way.. all that calc **** seems dumb. once you know how much .3 .2 etc actually effects the a/f it will be a breeze.

 

yes thats fine.

 

higher rpm the richer u want to be, doesnt have to be excessive, but the richer uptop the safer. so maybe do 11.5 for and then tapper it to 11.0 or 11.1

 

Ok then. Im going to go out once more with the changes i made above and see how much that affects the afr. Then go from there i guess.

 

btw once you go out and do another pull and see you actually CHANGED your tune, it will motivate you big time ...... it will make you feel accomplished and then you can keep going until you have your tune where you're happy with it.

 

just go do one 3rd gear pull and come back and post it.

 

Is anyone ever "happy" with their tune? I mean, once you start making more power it becomes addicting. You have to physically stop yourself from doing more and more and more.

You really notice this when you start using the EvoM virtual Dyno to see the power you are making.

Ethan....did you ever disable Lean Spool ? ?

 

thats true. but i think ill be happy for awhile once i crank the boost up on my new setup and scare the **** out of myself.

i told him to turn that off, but i dont think he did because his initial tune was with it turned on.

from your experience Appauldd, how much does .3 incriment effect a/f ? by approx how many points? or is this something that is different for every car?

 

To say ".3" for every car would be an inaccurate way of making adjustments. There are far to many variances from car to car to make the change the same for all.

It all comes down to logging the pull and making adjustments. I really take my time and do multiple pulls. I try to use flat ground, up hill, and down hill. I want to see as many load cells as possible.

My train of thought on tuning is a lot different than most "tuners". I could care less about big peak numbers.

My reasons are that the car, in most cases, will only hit those big numbers on rare occasions where it is on the dyno, the strip, or racing illegally. I try to build the fattest area under the curve as possible and get boost to come on a soon as possible.

I do so, as I stated above, in as many load cells as possible. Then the car will react well in all conditions. Ironically enough, by tuning this way....the peak numbers come naturally.

The best part of my methodology is that your car will be much more pleasurable to drive because you have power in the regions the car sees the most.....low and mid range.
