Screen Shot Comparisons J4J1 & My Tune

Very interesting. I should do the same for mine. I see the fuel enrichment function that I haven't touched yet.
What is your MAF cal'd for, 30's? My 36 numbers peak at around 1650~ish.
I haven't booted Windows in DAYS. I only use it for Caledit and EA anymore.
Too bad I haven't figured them out under Linux yet. Maybe if I get a few minutes. I'll get them done.
THANKS for doing this....

stock maf as far as I know...the MAF IS NOT CAL'D for an INJ. THE EEC is. I think this is one of the major things to "de-program" out of peoples minds....it realy causes more confusion than needed.

Good to see you are having fun Chad :rlaugh:

I don't know anything about having chips read :shrug:

Over the years, I've seen various peeps on the tuner sites say they had their chips read and they were shocked to find not much was done to enhance performance.

Not sure but, I have always suspect those chips were the kind you buy off the shelf and that kind of thing if you know what I mean.

Grady

Thats what I thought too, but my chip was burned with the tuner never seeing my car. I made 304rwhp 338 rwtq, an Air:Fuel ratio as flat as a pancake and near stock driveability. I don't care what they did, but I want that tune on my Tweecer.
 
It just amazes me how much he's leaned out the top of his MAF curve.
He went from 875 at the top to 1458. And the whole rest of the curve has been leaned out. I though he'd replaced the MAF, and was using the flowsheet....
 
He didn't lean it out. I don't recall what maf he's using, but I don't think it's the stock one anymore. The higher the number in the "Y" row, the richer the maf curve is. Those numbers represent the incoming amount of air, higher numbers equal higher amounts of fuel. (I'm sure you know all this, so maybe I misunderstood you :) )

Doh. I spaced it. Of course you are right. Telling the computer more air means it'll inject more fuel.
Still, his Sig says stock MAF. I know not to always trust the SIG, but this IS Grady....
If it is, it's still a big change. That's why I asked what MAF he had. (I understand about the calibration thing. For us, all it really does is put a limit on how much air we CAN flow through it..)
 
Yea his sig lists his numbers he put out with the stock maf, throttle body, and catback. IIRC, he told me he has since upgraded all those pieces, and just not gone back to the dyno. You're absolutely correct about the calibration. All that does is determine how much airflow the maf can read. Stock maf can only read like 925, whereas aftermarket ones can read much more, so you won't peg the maf and lean out up top. :nice:
 
So grady...load_limit_open_loop_vs_rpm

Your just running OL at idle right? and that is how it looks in the graph to make it do so (gen. speaking).

huh, interesting...I thought you had EA and had moved away from that? Or does it just run better with OL at idle?

:( Awww crap

Sorry Chris!

I guess Geo Cities has some kind of limit on amount of data transfer.
I made the files as small as I could, lol

I'll leave the files in place so ...... sooner or later they will be available for you to dl.

I quickly cruised through the other posts in this thread and noticed Dennis put the pics up if you did not notice.

Yes Dennis

That maf is a ProM 80mm shorty with a 30lb cal.

says it will be back up in an hour though.

Sorry about the download limit :fuss:

When it comes to all that web site stuff ...........
I really don't understand that much about it :bang:

Maybe I should have done like Dennis did and just made the pics for viewing only :shrug:

I thought the files might have been of more help to peeps if they had the ability to dl them :shrug:
Again ... what do I know about this stuff :rlaugh:

Great idea and thanks grady I cannot wait to look at it just to see and double check some things against.

Hope they are of some help to you Greg :D

I am honestly supprised no one has done this to any extent before...would make a great tute. on the subjet for ref. and explaining things.

Well I had the shots of everything that was different and thought it would not be too much trouble to make them available to all my gear head buds on :SNSign:

I am just amazed at how little realy has to be changed from all that we can change.

I mean after the MAF/INJ dial in...its like kill a few tables set commanded (check that it is going were you want it), get WOT spark and fuel setup, safe to start with...and then its like mess with idle but that I think comes more from becoming progressivly more and more picky about the tune as you grow to know the subject. Its like and People PAY for others to do this...hogwash

The self tuning thing is not as bad as some make it out to be :shrug:

Just a matter of geting started :D

You learn as you go is how I see it :banana:

Yep, I got them downloaded this morning. Great job with them. :nice: I just realized we have the same maf, I might try your curve just for kicks. Mine's rich down low, but it leans out up top (more due to my stock fuel pump than anything else probably).

When you get your chip back and the info about it ................

If you see some stuff from the chip you like ............

You can now use it with your tune :banana:

A comment about that "flat as a pancake ratio" :)

Now that you can self tune, you are gonna see much different looking final ratios with your self tuning efforts cause the dyno guy has filters to smooth or average out his display results where you don't.

Not a big deal really, just thought I would mention it to ya.

The first time I started to work with that data I was thinking how strange or different everything looked :D

Here I posted them all on one page. I'll add mine later:
Grady's pics
Dennis

Thanks Dennis for making another opportunity for everybody to have access to that data. :nice:

It was kind of you to do that! :hail2:

Another example of :SNSign: members :Teh-Win:

Maybe I should have done it the way you did? :shrug:

I've tried to pick up that stuff the best I can but I guess by now ......... everybody can see my self taught results leave something to be desired :rlaugh:

The whole web site or web page thing is a bit over my head :(

zenboy99 said:
Grady, thanks alot for that info.

What do your spark tables look like? I didn't see those posted on there.

Also what is trans_min_TP_for_torque_mod settings at 1020 near the bottom.

Chad, his spark_altitude_table, spark_bdln_table, spark_MBT_table, all 3 of those were deleted (all values set to 55). He (and myself as well) is only using his spark_base_table, which looks like it's set to fairly stock values.
 
CManT1914 said:
Grady, great job with those pictures! I might steal some of your data and load it into my tune (if I ever get the starter replaced, lol).

Wild Man Chris :banana:

Been a while since we've talked :D
and
Hope you haven't lost any skin from ridin around on that scooter :rlaugh:

Anything from that stuff that may help you is why I put it up :)

I just now realized one thing I should make mention of in that stuff.

The inj offsets are kinda ... in-between or ... a cross of T4M0 & J4J1

Sorry for the confusion :(

I only have dyno results with the sig combo so I felt it better to just keep the sig as is :shrug:

I know not to always trust the SIG, but this IS Grady....

:rlaugh: Well Dennis ... I choose to take that as ..............

you are saying something positive about me :banana: :rlaugh:

Surely you are not saying I might put up something that might be considered

controversial :D

adj : marked by or capable of arousing controversy :shrug:

You are correct Sir!

huh, interesting...I thought you had EA and had moved away from that?

Greg, I guess I don't quite understand what me having or not having EEC Analyzer (I do have it btw) has to do with me using Open Loop idle :shrug:

Help me to understand here if you will :)

Or does it just run better with OL at idle?

My O2's were cooling off at idle but ...... only by an ever so slightly amount.
I noticed over a good bit of time the KAMRF's would drift. :fuss:

My Stang is only a week end toy so we are talking about a long amount of time here ...... like months before I noticed the idle would start to become a bit unstable.

I tried the forced OL idle thing which made things much better so it has stayed in place :D
