The odd thing is the ATR logs the load as a decimal from 0 - 1. In the code I multiply the value by 100 when i copy it over to the graph data sheet.... i guess i have some more futzing to do

Mr.&Mrs.Magic

iTrader: (3)

got it-multiplied by 100. 3rd gear looks ok but 1st and 2nd deff need work.

now there's a switch from the norm... you're lean dude!

15 afr at 6500?

Mr.&Mrs.Magic

iTrader: (3)

any way someone can create a data collector for crusing using ATR data. All I can seem to do is make a big fat blob in the middle of the page.

iTrader: (1)

you need to do an x-y scatter plot with time on the x axis and afr on the y axis... check steps 11-19 on the first post

Mr.&Mrs.Magic

iTrader: (3)

tried that a million times in many diff ways and could never produce a chart. I'm assuming that excell 07 is very different in the way you make plots and graphs??

this is the best I can do.

r0tor

that looks about right... its just the scaling that makes it look wonky

to make it look neater, double click on each y-axis, go to the scale tab, input something like 12-15 for the afr and 3500-3800 on the rpm scale, and make sure the checkbox in the auto is unselected.

This looks excellent and very promising.
Is there an easy way to add another data line?
I'd be interested in seeing ignition advance.

(And spell "Analyze" correctly. lol)

^ Probably not. I think excel only allows a secondary axis.

MazdaManiac

iTrader: (3)

I don't want an additional axis.
Just another line with advance on it, along with the lambda, load and MAF lines.

alz0rz

iTrader: (41)

^ Oh yeah definitely.. but with the intervals that will need to be in place to accommodate all those values reasonably it would make the entire chart look a bit cramped.

if your talking about my spreadsheet... yea i can add it. Leading and Trailing or just leading?


In a few weeks i'll also be adding a dyno feature to go along with it...

hmm tried making a couple quick graphs with the cobb as the datalogger on excel 2007. This was my first time datalogging so they might not be the best graphs out there...

these are the results, do they look right?



First one was in 2nd gear WOT with AFR and RPM's showing




This one is 3rd gear WOT but didnt get to redline because road was not long enough and i was just testing the datalog feature out for the first time.

MazdaManiac

What calibration is that? The new base file?
If so, that is exactly normal.

\\Konig\\

iTrader: (4)

that is the customized file you gave me that ive been running for a while now, ive had it even before that dyno meet we had (the one where the mustang dyno was
acting up)

is something wrong besides it being slightly on the rich side? x_x

I'll have another automated spreadsheet for AP datalogging out shortly as they changed column header labels....

ShellDude

iTrader: (12)

Konig, your AFRs look like mine did before Jeff tweaked the crap out of them.

\\Konig\\

iTrader: (4)

hmm thats odd...

ShellDude

iTrader: (12)

Actually, now that i recall, mine were a bit lower... I bottomed out at 11 and pretty much stayed there. Yours are a bit closer to 12 than mine were.

r0tor: very much lookin' forward to the update.

will it be compatible with office '07?

r0tor

iTrader: (1)

I've been working with MM and the last edit seemed to work in 07 for him... apparently they changed the spreadsheet size or something in 2007

r0tor

iTrader: (1)

So I finished the spreadsheets for the AP logging and ATR running. They should work on Excel versions thru 2007.

... i even created their own cheesy website... Enjoy!!
