I am remote tuning. I need to get my wideband 02 datalogged. I have the Autometer guage which has a dataloger signal output and ground wires. I just got a firewire cable and was going to splice into the signal from the sensor. I would rather just use the signal output fromt he gauge. Has anyone done this with the autometer?

Matt

a quick search brought up these two write ups on datalogging a wideband with the XCAL3

I have read the first one, but that is not specific to the automete wideband. It would be different because theautometer has a analog output and ground from the gauge. I just wanted to know if anyone has used them. It would seem to be different connections that the first link.

You would just wire the analog output from the gauge (white wire I think) to the analog 1 wire in your fire-wire cable (orange). Then connect the ground from the gauge to the cable ground (Black), analog 1 ground (blue), and analog 2 ground (Green) in the fire-wire cable; then connect that connection to a chassis ground. The analog 2 and +5V will not be used.

i would verify the colors of the wires in the firewire cable because every cable is different.

Then its just setting up your XCAL3 for the analog input and setting up your livelink software with the formula for the AEM wideband for the analog 1 input when you select your PID's.

The wire colors on my wideband output are different, but ill try it in the morning. hopefully it stops snowing.

do you have the AEM wideband model 30-4100?

just checked the instructions and the 0-5V analog output is said to be white

you'll be good man; if your not sure of a wire, test it with a multimeter. And the snow finally stopped at my house. Around 20 inches in my yard; snow drifts to deal with tomorrow.

No i have the autometer wideband. the wire colors are different thats all. For some reason my computer wont stay on unless it is plugged in, so i cant do too much. I would have loved 20 inches of snow. sounds like its time to go wheeling with the trucks.

OK so i got the firewire connected, got the xcal3 logging the wideband output signal. But its range is not correct. The autometer gauge output is 0-4 volt range, but i think the SCT is ranged 0-5 volts. The SCT is reading about 1.0 higher than the gauge. ex. gausge reads 12.0 SCT reads 13.0. And i dont really understand all the equassion.

maybe this will help.......

from the SCT forums and trying to confirm the information from a few other sources, the autometer gauge's output is 0-4v over 10 points for A/F between 10:1 to 20:1 and is linear.

Forumla= 10+(v*2.5)

ex:
at 0v, 10+(0*2.5)=10 A/F
at 1.88v. 10+(1.88*2.5)=14.7 A/F
at 4v, 10+(4*2.5)=20 A/F

try that formula; im not sure which one you are using. The AEM formula wont work the same.

thanks a lot for the help, I will try that out tonight.

do i have to have that equation in the SCT and in the livelink data? I put in into the live link and it was not reading the same as my gauge.

^should just have to enter the equation into the livelink software when prompted after you select the proper analog input PID.

how far off is the livelink reading compared to the gauge? i know some people had to play around with the multiplying number for the AEM equation for it to read properly; might be the same for you. ex(instead of v*2.5 maybe its v*2.8 or v*2.1; just make sure livelink reads the same through all a/f outputs from the gauge)

a member named Blivit is the SCT representative on this site; try shooting him a PM if you cant get it figured out. Hes always helped me out.

I got the equation. i used 1.5 seems to be really close. Now i just need to figure out why live link freezes when the car is at idle. I shot SCT a email last night. see what they say.

Do you have an X2 or X3? Which version of livelink are you using?

There are a few known issues with livelink on the SVT with the X3. I have worked with the engineers on several occasions to get things fixed but unfortunately they cannot find the problem. It is frustrating as I work here and cannot accurately log my SVT with the X3. I have to use other things when I need to datalog.

I keep pushing to get this fixed but unfortunately with the SVT being a low use vehicle it is not very high on the priority list. If I didn't own one I doubt it would be looked at all.

I have a SF3. livelink 5.1 i think it is. i uninstalled it, to reinstall it. i just downloaded it from SCT site last week so whatever that would be. Yeah i emailed and call SCT yesterday, known issue with the SVT focus and they didnt seem real concerned. Kinda sucks that we spend 400+ bucks on the programmer and it doesnt all work like it is supposed to. Should get a customer saticfaction rebate. lol.

The X2 works well as does our new TSX module. For the X3 a different device driver was used and I think that is what causes the problems.

Yesterday and today though I was able to find a version (an early test version prior to 5.1.0 that was released) that is working well with the SVT here. I have had it logging non stop for 90 minutes with 20 parameters this morning.

Send me an email at miker@sctflash.com and I can send you this version to see if it works for you.

It does not seem to be an issue with all SVT , some have strange 123478890327.88890372 spark advance numbers , some freeze up and stop logging , some have say 1.093 in lower case and .821 stft in upper case where they dont match then some wont datalog at all , the MAF V still isnt the correct numbers in voltage as well even with the new non released version I have been testing

Its random between SVT and the x2 is doing this as well just not as bad , I have been fussing about this for about 2 years and nothing gets fixed as well as issues still with the tuning software

The Raptor datalogs the SVT flawless so I know they have the ability to get it right

Tom

If some other datalogger can do it, I would think one as popular as SCT could get it right. Seems like not that many companies give a crap about the SVT focus.

Electrical wiring is not my forte.

I have an X3, but the whole wiring thing worries me when trying to connect to a Wide Band O2 sensor.

Given I am electrically challenged , am I better off with a Innovate LM-1 Air/Fuel Ratio Meter KIT???
http://focus.c-f-m.com/freeshippingi...ometerkit.aspx

From what I can see, this is virtually plug and play. I am assuming this will log AFR for me (then download to laptop) in a format I could email to Tom for example for remote tuning?

(ps. Given I have the rear O2 sensor turned off, I am also assuming I could install the WB02 in that position, and leave it permanently???)

Please if I am going to do this PLEASE do the AEM and with everyone here we can get you wired to datalog on the xcal , it isnt as bad as it all sounds

I checked and I have my AEM hooked just like this. And even with playing with the equations I cannot get the LiveLink to match my gauge. The LL will not get out of the 10 range, while my gauge is between 12-13. I can change the +10 part to +13, but that just puts the reading at 13 on during the datalogging. So Im not understanding something right I guess. Shouldnt the LL match the gauge and fluxuate with it and every thing else?

If it is not changing from 10 then you do not have the connection wired correctly. It is an mx+b equation where m is the multiplier, b is the offset. You are putting in values for m and b so that leaves x which would be the voltage, to be 0.

If you have a multimeter, check for voltage coming out of the output from gauge.

Is this and X2 or X3?

Its a SF3.. and I hooked up the analog 1 (orange) to the white wire from the gauge, grounded the 3 ground wires (black, blue, green) and am not using the analog 2 (red) wire and the white wire I believe from the cable.

And its been too long since I have sat in a math class!!!

Ever heard of K.I.S.S.? Keep It Simple & Stupid... <<<<<< thats me.. hehehe

What formula did you use? Or do you not use a AEM setup? Is there a way to get in touch with you on the phone? Maybe walk me through this if its not to much trouble... I gotta drive and datalog tomorrow, but need this a/f working

Personally no, I have not used the AEM. An analog input is an analog input though. Right now I am using the Dynojet wideband commander in both of my cars.

An easy way to tell if you have voltage is to not enter in an equation. Let it log or show raw voltage. If it is 0 then you have no voltage to the cable.

The firewire cable you are using, did you buy it from us directly or from somewhere else? Cables not bought from us work just fine but sometimes the pin out will be different.

It is not easy for me to get to a phone here. We do have a good tech support department though that can walk you through getting it to work.

Ok I'll try the no equeation part and see what happends. Shouldnt I be able to hook both analog (orange and red) wires to the gauge? I would just have reading on two diff analog channels right? Just a thought.

Yes, there is no problem with doing that.

the cable wasnt from you guys. But I figure If I hook up all the wires. then I should get a reading somewhere.. I'll check the blue and white wires coming from the gauge to see which one has voltage.

Because the cable did not come from us, the colors/pin out may be different.

Im only checking for volt at the white and blue wire coming from the AEM gauge correct?

Whichever wires are the output and ground for that unit yes. If there is voltage there, then you will just need to figure out which wires to connect to on your firewire cable.

well... the blue wire from the gauge, that no one seems to be using, has 2.5v. the white wire from the gauge has .4-.5. And there are only two wires to be used from the cable. I hooked the cable analog wires to both of the gauge outputs at seperate times, switched them anyway I could to change the configuration and Im still only getting 10.03234 on the LL

How about this one. SCT get up to date and set up livelink to work with windows 7.

I have, honestly i find it hard to find the livelink downloads on the site. I guess its just me, i wouldnt have looked under tech support for the livelink software. Found it tho.

With the car running, whichever wire is the output should not be a static voltage. It should be moving around but centered near a particular voltage.

Blivit, can you tell me the part number and price for the firewire cable you sell. I've looked around your site but can't find it.

Thanks.

Not sure why it isn't on the website. Part number is 9608. The price I am not sure on right now but it is no more than $10-$15.

The cable is on the SCT site, I saw it yesterday. But I finally figured out the cable I bought. The two analog lead and ground wires are reverse of the SCT cable.

On the one I used: (bought from a computer store)

Black = ground (same pin as SCT)
white = 5+ ext. (same pin as SCT)
orange/red = ground wires
blue/green = analogs 1 & 2

No wonder it wasnt working right??? lol
