Well, I think the 85 i have here is suspect.. It is connecting, but not sending data... The two 86's and the 88 are sending data.. Now of course, I need to figure this thing out.. I am hoping that I will be able to 'see' and 'monitor' more on the data logs..
Dave, I emailed the data logs to myself and oh boy what a mess of numbers... Not sure how I will ever decipher all the 'code'.... Sigh...
Yup, now we are both at the same point. There are some starting points like tps voltage at idle, etc.
I am still searching for what they should be vs. what they are. A standard good starting point would be nice to have compiled, and I am working on that right now. If I could find the correct numbers, as if it was a new car for all settings, I will have a base...... still searching. I might have to buy myself a service manual for that.
And once again congrats on getting data!.... now, what to do with it?
We installed it on my tablet.. For grins I decided to try it on my 88GT AND PESTO, ITS WORKING!
But, when I tried it on my 85, no workie!
Sooo, I looked at the Fiero ALDL connector . The '85 and '86 have four pins in the connector... A,B,E,G
The ,87 has A,B,E,F,G
The '88 has A,B,D,E,G
SO.. My guess is a different data stream for the three varieties...
I find this a little confusing as I have never heard of any difference between years in regards to connecting to different pins in the ALDL port. The ALDL cable I use to connect to my laptop works with my '84, '86 and '88 Fieros.
Are you sure your 85's ALDL connector isn't simply mounted upside down (compared to your '88) and that you're possibly plugging into it incorrectly?
Notice that the two images below are showing the same port... but one's flipped over.

Patrick... They are indeed not flipped over.. They are in fact wired wired just as I said.
The 85 is not sending data for some reason.. The Bluetooth is connected and the LED light is blinking its normal ' streaming' colors...
I'll have to make sure the pins for that ALDL are making contact .
The two 86's and the 88 read fine.. So the one streaming file is indeed the one that is needed for all years..
I have an 86 GT here with a 4.9 in it that has had gremlins for *years* I'd live to be able to read that set-up with this scanner...
*edit to add* I've never bothered to look at the ALDL for diff years, as the A B and G are consistent.. Those are the only pins I've ever needed. 😁 Also, the ALDL plug for the Bluetooth scanner can only plug in the one way.. Idiot proof 😁😁

Note: 85 may have an aftermarket "performance chip." Many of those do not stream data to pins E or M no matter what scanner is used. All Fiero V6 and older L4 use E. 87+ L4 w/ 1227748 ECM use M.
Only look at key on top or bottom near C & D. ALDL can be mounted either way in Fiero.
Shift light doesn't ground thru ALDL pin F for most cars. F is test point for TCC lockup. SES going to pin D is not listed in many SM Aldata etc for Fiero including 88 FSM... (Pages 8A-20-2 & 8A-21-0) And when you look at picture above most C and D are empty. Later years may have D as backup to read error codes using a "code reader" w/ a light. Readers are mostly crap and if they have a light doesn't work w/ many GM cars.
That's great... but it would be a little more reassuring to hear that a vendor would act in the same manner after a sale.
Yeah.. Bummed I never heard.. But, that's why I've been here nearly 20(!) Years.. We lean on each other for help.
I'd love to figure out how to read the data logs.. Maybe I'm not exporting it correctly? I email it to myself, and open the file in my viewer.. Its a series of numbers and lean/rich values.. Makes my head spin... Haha

Thanks, Ogre.. Some solid info.. I'm hoping to greatly explore this scanner and really use it as a go-to tool..
I just received my USB connector from Red Devil and I'm having touble too. I am trying to scan using TunerPro RT but after loading the suggested definitions, the furthest I get is "connecting" and it just hangs there. Both Marc from TunerPro and Phonedawgz have tried to help me, but I just can't connect. I assume I 'm not using the right definitions as I confirmed I'm on the right com port so what else could it be? Does someone know what the correct .xdf and .adx files I should be using for an '84 2.5?
