Is there anyway for me to make my datapage show the AFR 10-20 range instead of what it is currently displaying. i would like to datalog and see my afr's

Ok, im going now to take the opportunity to steal this post and teach everybody how to view AFR's on your datalogs when you only have voltage available to you.

First you do a datalog, remember to include the O2 sensor input, then you save this datalog, by default the Haltech saves datalogs as a CVS file (in Old DOS it was something like .HDL extension that could be renamed to CSV).

Then, open your microsoft excel program and import the file in there, make sure you get each set of values in its own column.

Here's were the fun begins, take you particular wideban O2 sensor controller's user's manual, and find out exactly in what manner they obtain their AFR calculation, you will find that most of them apply a formula to the voltage input and convert it to AFR.

In this example, the datalog was done using the PLX Device M300 display, which its formula for obtaining AFR from voltage goes like this: AFR = 2 * Vout + 10.

Now, do a new column in Excel, right next to your O2 sensor Vout and name it AFR, then, using the Sum function in excel, tell the new column to input the values from your O2 column, integrated with this formula, like so: =SUM(((2*I5)/1000)+10) note, that i divided the voltage by 1000, because the Haltech datalog displays it in mV and the formula expects V, so, 500.234 = 0.50V = ~11AFR.

So, here in the example shown, you see that mVout has transformed into AFR, you have to remember that the specific wideband you use will have its own formula for obtaining it. On the Innovate you have to extract it using a proportion, since they only tell you that 7.35AFR = 0v and 22.39AFR = 5v.

I hope this helps people get past the voltage to AFR convertion woes.

If anybody has questions, feel free to ask.

So you hooked the 1v linear output of the WBO2 controller to the shielded grey wire on the e6k?

We're talking widebands here, not narrow band sensors. But yes, if you'd like to datalog a 1V sensor that is what you do.

Mr Claudio i have a map that I am starting with that is very rich from 3500 on up is there a better way to take the fuel out on top without going through each rpm range page, for instance say i would like to take 5% out at one time from 3500 to 5000 so on etc. by the way my PLX is working excellent with the IMFD display I would highly recommend it.

SaabGuy

Yes I have a PLXM300 WB controller which can output linear 0-5v(WB) or linear 0-1v(NB).

Do I hook the 0-5v output to the shielded grey wire? Ive done this and I cant get my Haltech e6k to recognize anyything other than zero voltage.

If you get zero voltage i would ask did you use the right output wire from the Wideband? Did you go to the O2 sensor setup and tell the haltech to read from 0-5v? try connecting the signal to the spare AD intput and leave it as General and see if it gives you anything.

lilfreddie

thank you for the help Claudio, i selected the wideband in the o2 setup but it was still set up for 0-1volt instaed of 0-5. i am also going to experiment with the excel spread sheet tomorrow if Barry comes over. thank you for the help.

lilfreddie

well i figured it out with Haltechs help today, what i am doing is using the optional GENERAL input and feeding the input with the 5 volt output from the wideband and it is working great. that is also letting me use the narrow band output into the origonal o2 input on the Haltech so i can go into closed loop. i am so happy when a plan comes together. now i got to figure out how to make an excel spreadsheet, save the datalog on DOS imoprt it into the spreadsheet and start some tuning, sheed you know thats right!~ anyone close to help a brutha out

Didnt i say to do that on my last post???

lilfreddie

yes, you are the man, i just needed a little help with it on which wire to pick and where to select that AD input and turn it on. thank you for the help. Is there a way to do a correction across a larger range than 500rpm intervals

crispeed

How about just using the E6K v 6.34u software that shows AFR's on the datalog/page once a wideband is used on the spare A/D. You must use a wideband that can be calibrated from 10:1-20;1afr at 0-5v.

lilfreddie

crispeed can you elaborate on how to do this. thank you ahead of time.

Do you have that version of software? also, what wideband has that specific characteristic?

crispeed

The software was originaly designed around the M&W Uego wideband which was one of a few readily available at the time. Now just about every wideband out there presently got programable outputs so they are compartable.
And yes I do have that version of the software and always use it with the E6K. It's makes tuning a lot faster using the old school dos software. I actually downloaded it off the net many moons ago. I guess you can contact Haltech for more info. It's the 6.34u version. I think the 'u' stands for uego.

crispeed

Ok I just found it again from this site.
Download at your own risk.

is this the same version that on on Haltechs website

Actually its not, its called 6.34u "U" for uego. But thats one of the things you dont see on the Haltech site, you have to ask for it.

Kinda like a "high boost" version of the DOS software. But ssssshhhhhhhhh.... you didnt hear it from me.

crispeed

Yeh ''high boost'' dos software for 1,2,3,4 plus and 5-bar map sensor compatable.

lilfreddie

that e6k version u is the same version i have, when you open the info page on the "u" version it does not have a difference

Claudio RX-7

As previously stated the "U" version only displays AFR's in the O2 sensor field instead of Voltage, did you try gonig online with it to see it?

lilfreddie

i'm done the afrs are not being translated no matter what i do. if you could give me specific insructions i think i could do it. the only thing that is on my data page is 0-5 volts not afr's. it would be really nice if i could get afr's to read in that area..........

Then just do the logs, convert the files to CSV's, import them onto Excel and apply the formula for your particular controller easiest solution i can think of. You should also do what i've grown used to, which is remember what voltage means what AFR, im not suggesting you learn the entire scale, just know that if, for example, you're tuning for 11.5 and that is equal to 1.3v, keep that in your head when you're tuning, that way you can at least know if you're off.

Hey I know this is a blast from the past, but I just wanted to ask do you only need the software 6.34u or do you need to get new firmware as well? Thanks buddy!

lilfreddie

once you download you are ready to data log AFR's!


WHO DAT!!!!!!!!!!!!
