Air/Fuel gauge working properly? [Merged 10-6]

[perley03]

First off, just search. This topic is covered many times on this site, so 5 mins of your time to search would just about cover everything you need to know about dataloggers. Here, i made it even easier for you. This tech article should tell you what you need to know. http://www.dsmtuners.com/forums/showthread.php?t=203316
It shows how to make a datalogger cable, and even gives you the link to MMCD software (free by the way) and how to hook it up. If you don't want to make your cable (cost me like $3-5 at radio shack, and 10 mins to make) you can search on eBay for the cables as well. http://search.ebay.com/search/searc...00&fpos=04401&ftrt=1&ftrv=1&saprclo=&saprchi= click that link, it'll take you to all the cables on eBay.

I'm sorry, but I have been looking for data logger information on the search and I keep bringing up the same thread that is not helping me at all. I am not lazy to look for stuff in threads, honestly I rather read than ask people. takes even longer sometimes. thanks for the info. though I really appreciate it.

 

[perley03]

Well I didnt intend that you were lazy....Im sorry if I offended you. Its just that alot of people before us have been in the same situation, so they have already posted info about these topics we run into. All we need to do is do a little searching to find the right answer. If you cant find it, then you can post a new question. I dont mean to offend people in anyway, and if I do, let me know. Im just tired of seeing people posting the same questions over and over and over.....and I'm sure I'm not the only member on here that feels this way also.

 

[perley03]

Did my post help you at all packinkimber45???? If not, what exactly are you looking for in a datalogger? There are alot of different programs now, I'm just too cheap to spend $100+ on a datalogger when i can build a cable and download free software that does the same thing. Although if you go with pocketloggers.com, they have tech support if you run into any problems, as these freewares do not. Just let us know what you want for a datalogger, and by the way the Palm m100 is a good model for most programs. You may have to download the new OS software for it, just go to Palm.com and find your model. As for that cable i made, you need a hotsync cable that has a serial end on it. I got mine off eBay for $12 shipped, and it works great. Like I said, just let us know what you exactly need, and im sorry if I offended you.

Installed my autometer af guage, and all I get is first lean led. after warming up engine same. I know I installed it right. this is the second time I have done this. light does not move up and down. stays on the same led. when I blip the throttle, light just get stronger, but not responding... any ideas. thanks.

A dead o2 sensor would give this result, if the led does not move it is possible the sensor is not going into closed loop. I know this may sound weird but is the o2 sensor plugged in? Did you tap your gauge on the blue wire on the ecu?

 

[packinkimber45]

perley03... no offense taken... just didnt want to sound like I am just being lazy. I personally dont like to irritate people with questions. however if I am not able to find what I want, it is the only option I have. but yeah dont worry, you didnt offend me at all. thanks for all the replies. I found a hot sync cable from ebay for like $7-$8 with shipping. it does have the serial port on one end. do they come with different size serial ports? I dont believe so, so I will buy the one from ebay. that link you posted on how to make looks pretty simple, and i would rather spend 5-10 buck rather than the prices people are wanting for these cables. I will be making one soon and installing on the car and once I get the sync cable I will repost on my progress.. thanks again


autorst.... light on af is pretty dim, when I rev motor even when warm, led stays on one spot and just gets brighter. I actually spliced to the af test wire under the dash in passenger side of car. dont really feel comfortabe hacking at my ecu harness unless I absolutely have to. I am switching my 02 sensor from my 91 gsx that I know for sure is working since the af gauge was working in there tomorrow. I will repost as soon as I have done that. since on the subject, is it the same 02 sensors for all 90-94 dsms? how about a jdm motor? thanks again guys, you have been a lot of help. I love this site. lots of things I have learned since I have been browsing on here.

 

[perley03]

that hotsync cable should work...just make sure it is made for your palm model. All of the serial ports are the same, should be a 9 pin. If you want i can make you the cable and send it to you, you just pay the materials and shipping. I dont mind spending a few minutes to help a fellow dsm'er out, if you are interested just shoot me a PM. As far as a program, MMCD seems to work fine for me. I gave you the link for the free download. Just make sure you update your Palm OS and the Hotsync program before you install it. Other than that, you should be good to go.
As far as the O2 sensor, they should all be same for the 1G. If not, check a Haynes or Chiltons manual, they will tell you which wire is what, and you can just splice the old connector onto the new one. I did that, but i just bought a universal and used the old connector. It works just fine. Rather spend $45 than $120 for one, plus having some fun while im at it. Hope this helps.

I dont see a problem with hacking into the test wire by the passenger kick panel. Not a bad idea since you dont want to mess with the ecu harness. Just to double check you have the gauge tapped at connector c-56 in the Chiltons? All o2 sensors 90-94 turbo should work

 

[packinkimber45]

thanks for all the replies guys, really appreciate it. I havent had a chance to switch the o2 sensors out yet, so no new yet. will tonight or tomorrow though.

Perley03..... thanks for the offer. I think I can attempt to make the cable. it doesnt look that hard to make. thanks for offering though, very generous of you to. I did purchase the hot sync cable from ebay. not the same one I was looking at before, but it should work. it is for a palm m100, difference is the hot sync button on the cable and priece....hope I dont need that.

auto rst..... I'm not very good at reading schematics, so as far as verifying thru chilton, I havent. although it is the same wire I used on my 91 gsx (spade female plug that is single wire attached to wire harness under the passenger side dash). I got the info thru vfaq, so I am possitive it is the same wire.

like I said guys, thank you very much for all your replies. I will post once I get the cable made, o2 sensor switched and verify af gauge, and once I verify palm working with cable and program.

 

[perley03]

Well you really didn't need the cable with the hoysync button....its just used when you upload stuff from your computer to your palm. Also Palm OS has the hotsync right in the Main Menu, so the button is just a shortcut. You don't need it for datalogging. Let us know how MMCD works out for you. I like it alot, the first time i used it I had to unplug the wires a few times, but after that it works fine. Good luck, and keep us posted.

That sounds like the right connector, but when talking about wiring next time include the color of the wire also Keep us posted

 

[packinkimber45]

hey guys, I have a little bit of progress. I just got in the sync cable, downloaded palm software, mmcd tools.... but I cant get hotsync to work. tells me that both my devices are not connecting (pc and palm) and to check my settings. I have no Idea where to go from here. I got all the supplies to make the cable, but I cant sync with my 2 pc's. even transfering the program to my palm and vice versa... any ideas? I dont have the original cd for my palm since it was given to me. dont know if I should just scrap palm and buy one, unless I can get this to work. thanks again guys.

 

[perley03]

What model Palm do you have??? You don't need the cd, just go to Palm.com/us then click on Support. That page should list the model you have. Once you found your model click on it and it will bring up a page and at the bottom it will have a link to an upgrade for your palm. Download it, but before you open it dowload Palm Desktop, its in the middle of the page under Windows Hotsync. Run that install the program and you should be good to go. If you are interested in another palm I have an old Palm IIIx that i dont use and it works. Comes with cradle and updated software and book. I'll let it go cheap. If you want it let me know.

 

[packinkimber45]

yes! I got it to work. was up till 5 am this morning trying to figure out why my pc's not recognizing the sync. had to change to serial setting on sync in the task bar that I didnt notice was in there. got mmcd downloaded to my palm. thanks for offering the palm man, I appreciate it. I think I am good to go though.thanks. will make the data logger cable and do some logs and will repost.

 

[jongreene]

Sorry to basically start the thread over, but my A/F gauge reads rich 24/7. One solid bar all the way up to rich, it doesnt blink up and down like it should, and my car is not as rich as the gauge says. Is it just a wiring problem?

 

[dsmgrimreaper]

it's broken

 

[packinkimber45]

ok guys... I switched my o2 sensor out today with the other one I have in my gsx, and now my af gauge responds. after warmed up it is still in the lean side. highest it got when warmed up during idle was 2nd lean led. wont go up and down from stoich to lean like normal. when I do blip the throttle though it goes up to lower part of stoich (towards lean side). it does seem to be a delay though. after I have blipped the throttle is when it does that. during idle though it stays on lean and not fluctuating to stoich and back down to lean. is there something wrong with wiring? o2 that was in there before was definately bad since it was not doing anything. will be switching my maf assymbly monday. got my palm to work with my pc and have mmcd downloaded. could the tuning on the car be too lean on the safc per result on the af gauge? since I am putting another maf assy. in the car, can you guys tell me what baseline tune I am ok to start with on the safc? thanks again.

If i remember correctly on my 91 laser the a/f guage would do this until i went for a drive, at idle after i just started it, it would always read in the lean area until i drove it and got it to go into closed loop. It is also possible that you are tuned too lean, but there is no way for us to tell yet. Get that datalogger working and look at your low fuel trim, adjust the afc until the logger is within -+ 10% of 100 on the low, then see what your guage tells you. Should be stoich. What maf assembly are you gonig to use?

 

[JBDdsmer610]

What you should do is just go with a wideband like the AEM ugo. another good thing about a wideband it makes it great for tunning

I havent taken the car out for a drive yet with the af gauge in there. still some things I want to get up to par before I do. still need to flush radiator, get stripped filler bolt of rear diff off and change that fluid, switch back to stock maf from my gsx. engine was warmed up when I did check the gauge, but will definately as soon as I get all other taken care of I will take for a drive to see what happens. I am actually making the data logger cable today, so some time this week I might have the chance to log. as far as looking at my low fuel trim, is that something I need to do a log for? or can I just monitor this via my palm? not sure where that setting would be on my palm on mmcd tools... by the way when I was playing around with the palm and mmcd tools I noticed on page 4 there is nothing. is there suppose to be other features in page 4 for logging? also on "H" section nothing. just wondering... dont want to mess with a program that I dont have downloaded properly or that is corrupted or incomplete program. as far as adjusting on my afc... not familiar with it. when I bought the car it was already in there, so I will have to familiar myself with it as far as how to use and tunning. thanks again.

unfortunately right now I dont have the funds to spend on a wideband. later I do plan on going with wideband, but right now I am trying to spend the funds I am able to get to get the car back up to par in good running condition.

I disconnected my Air/Fuel Gauge for a couple of days cause i had to do some stuff and it was in the way, and when i reconnected it, it would come on but not really work. It says im running all the way lean and every once and awhile it moves to the second leand LED.
And i know its supposed to say lean until the O2 sensor is warmed up.
Any Suggestions.

 

[95TalonOwner]

make sure the wires are connected right. If that doesn't work, maybe you dropped it or something when it was out of your car and that's why it doesn't work.
