obd2 scan program for free

[cocobolo95]

Here's a link to a free scan tool software for obd2 cars. It was designed for f-bodies but should work on 1996 to 2007 obd2 vehicles.
Free Cloud Storage - MediaFire You will need an elm-327 cable to go with the software.
(1) there is an instruction doc in the zip file, excutable file, and data files. (2) Download zip file and place in folder of your naming and unzip. (3) tested in XP and 7 (4) you can contact the author at
garydoug98ta@gmail.com The author wants people to test his program. For those advanced enough to know what PID's are, he would like for you to get back to him with the PID's your car has.

I keep posting a link to a cable on amazon. It works one time then stops working.

Btw the link for the cable doesn't work?
Otherwise thanks for that.

[94Trans-Am]

All those cables say 96 and newer so thats mine out.

[hopkins_fam]

That why he said OBD2 96+, I take it hince your name you have a OBD1 94

My bad.

coco, downloaded the exec's (They passed virus and Malware scans) and read through the PDF file. Looks like a decent free solution for OBD2. Problem is I only have 1 OBD2 vehicle a Ford product others are all OBD1. Really interested to see where this goes...AKA: FreeScan . The .pdf 'GD Scan Guide' looks like it's using SAE J/1979 standard PID's so it may work for the standard major parameters on my 2003. Think I may order up a cable and give it a test. Going to search around to see if I can find a manufacture specific PID list for my '03.

Just downloaded the files, picked up a trojan off the site itself. Use caution.

Bob, I believe what GaryDoug wants, is for people with cars other than f-bodies to try out program and see how it works. Your Ford obd2 car is a perfect candidate.

Actually any 96-02 car that works would be helpful, especially the F-series ones. What I am needing is a list of PID's supported for each year car and each version engine. It's not absolutely necessary, but I would like to know if I can just run the scan of them without having to require the user to scan for them all. Email me for the instructions on how to create the PID list and I will be glad to share the identified results with you.
The first version is just the standard mandated PIDs and may work for most cars. I know it works for a 98 Bonneville, 98 Firebird (V6 and V8), 95 Lexus ES350, and a 2006 Hyundai Tiburon. It may have a problem with the 99 and newer cars because of the multiple controllers (It only assumes a PCM on the bus) The second version may work on most cars too, but I will be shifting to the GM cars only to make use of the proprietary enhanced PID sets and bi-directional controls, and will be directly addressing the PCM to avoid conflicts with the multiple controllers on the newer cars. So if you want a non-GM version, stick with the 1st version. For GM cars, stay tuned for more capable versions.

I see there have been many downloads of the two versions and I have a question. Has anyone had any problems using the version 2 program (GD-Scan2.exe or GD-Scan2a.exe) on an 96 or 97 V8 (LT1) engine?

A member has reported that some features will not work on his 96 car, however it is "Hypertech-ed"; and I can't tell him if that affects the enhanced data capability. Thanks

Edit 8/22: Another user with a factory (unmodified) 96 PCM reported good results

Off topic but the link to the Freescan program is dead?

[94Trans-Am]

Its definately down atm , here's another link:

FreeScan | Free Communications software downloads at SourceForge.net

[cocobolo95]

Yes frescan web page is dead. Don't know if it's for good or just down for a while. It's been dead in the past.

My ADL cable finally arrived after customs obviously decided they had kept it long enough.
Just to say that OBD diagnostics supply a driver disc which is also crammed full of scan programs.

I am well along in writing an OBD1 scan program for the 94/95 LT1 F-series cars. It will contain more data than the Freescan app and about the same basic material as Datamaster (a few less "cute" features) when done. I will add some bi-directional actuators as well: Fans, A/C, MIL, evap purge, EGR duty cycle, AIR pump, and closed/open loop mode. Most of it is already working but I will take some time to dress it up and add some graphs (maybe) and datalogging before offering it for free. Anyone who wants to try it now (or at any time) can just ask.
