thanks a ton! I checked my service manual and couldn't find the map to all the "words" do you have it somewhere, or do you know where it would be listed in the service manual or on line?

In TunerPro, when you look at the AFR Mode Word flags, hit F10. This will turn on the "Item Comments/Help" and show what all the bit flags mean. You can also find this info in the $0D hack. HTH

Where is the $0D hack?

If you can't open the .SRC file format, just rename the file with a .txt extension. Enjoy!

I'm making this too easy for you guys! LOL

Does any of this work with the Body Control Module (BCM)? I'm trying to do some lighting stuff (like export rear fog lights). Can't find anything out there except to buy a $3000 Tech 2 and write "Mr. Badwrench" on my shirt with a marker pen. OBTW - I have been using an AutoXray (read only) for years and love it.

The $0D broadcast code and all the other stuff in this thread is for EPROM based OBDI (pre 1996) stuff not the Flash ROM based OBDII stuff. Good luck in finding something for the BCM. All the OBDII stuff I have seen, and there is quite a bit of it out there, is unbelievably expensive. LS1Edit comes to mind. $450 or so for a single PCM license. You may be on your own. If you do come up with something, the diy community would much appreciate it if you would share.

Hi Guys. I am very new to this stuff and have downloaded the Tunerpro RT and have cables on the way. Now for my question, I'm not trying to change anything (yet), I just want to see if I can find out why my truck is missing at idle. Can this program be used to look and tell why I have a miss. And what progams do I need for a 95 chevy with a 16197427 ECM. I have downloaded the 31voo2a.ecu mask $31 file from tunerpro's site. Is this the only file I need to download just to take a look at what my engines doing? I'm getting some great info out of this thread (for later use), so any info on the questions I asked would be greatly appreciated. Thanks

What model truck and engine do you have? The $31 mask is for HD trucks. Most likely you are running the $0D mask. Just to clarify, an .ecu file is used to tell TunerPro and other programs how to "decipher" and modify the contents of the PROM. It has nothing to do with datalogging. TunerProRT can edit PROMS and log data. It uses an .ads file to "decipher" the ALDL datastream. Once you can log ALDL data, TunerPro or any other datalogging/scanning software will not "tell" you why you have a miss at idle. All it will do is show you the trouble codes and ALDL data in a legible format. It is up to you to figure out what is wrong. Read my post at the beginning of this thread, then, read all the referenced material, then re-read it again and again. Things will start to become more clear. This stuff has a steep learning curve but can easily be mastered with persistance. Welcome to PROM tuning/datalogging.

I have a 95 chevy ext. cab 350 5.7. All I'm wanting to do is watch what the sensors are doing. I can do that with tunerpro RT right? I'm not going to be jumping into changing anything just yet. I know I can't use WinALDL because of my ECM baud rate. I know it won't per say tell me why I have a miss, but by watching what the sensors are doing I can get an idea. I'm not throwing any trouble codes, so that's why I'm wanting to watch the sensors are doing. What would I need to just watch what the sensors are doing. Thanks. BTW this is what I got off of tunerpro website. 31v002a.ecu $31 16197427/16156930 95 C/K Truck or Van, 5.7/7.4 That's my truck and engine and ECM#.

Yes you can do that with TunerProRT. Don't be too sure you're not throwing a code. I have seen too many SES bulbs burned out. All you need to scan/log ALDL data is TunerProRT, the proper .ads file for your PCM and an 8192 baud bi-directional (if you wan't to be able to reset trouble codes) ALDL cable. You might also want to check out Datamaster. It is much more user friendly and IMHO is superior to TunerProRT. You can download it and use it 20 times for free, after that it will cost you $100. IMHO if you "get into" PROM tuning, it is a worthwhile investment. TunerProRT is tailored to the more advanced user but still an excellent choice. I use both. Lastly, if you want to edit PROMS, try the $0D mask. I'm 99% sure that is what you have. Do some more research and you will see this.

Thanks for the info. I know I'm not throwing any codes because I have checked. But I was wanting to watch what the sensors were doing. Thanks, I will check out Datamaster.

Well I tried Datamaster. It seems like a very good program, but I can't get my com. port setting right. It won't let me choose any now. It was letting me choose between 2 & 3. Now it just has the "none" box checked. I unistalled it and will try tomorrow to reinstall it to see if that helps. Man I would like to get that program running, it seemed like the best one I have seen yet, for what I'm wanting to do. Update:: Since I'm about out of chances with Datamaster, I went back to TunerproRT. I think I finally got everything I need now. I'm going to try again tomorrow, hopefully my cables will work. Thanks again guys, and I'm sure this won't be the last you hear from me.

Ok guys I tried the TunerproRT this morning. It says it was connected but it was showing no data. The cable I have is just plugged into the terminal A and M. Do I need the 10k resistor jumper across A&B? and do I need a 12v power sorce hooked up? It for a 95 chevy 350 5.7.

[HaulnA$$]

Which cable are you using? Which .ads file are you using with TunerProRT? You definetly do not need the 10K resistor. You are connected to the right pins if your truck has the 12 pin ALDL connector. Some '95 TBI trucks have the D shaped 16 pin ALDL connector found on OBDII vehicles. It is this way on my '95 S-10 V-6 TBI truck. If this is the case, ground is pin 5 and 8192 baud ALDL data is on pin 9. As for the 12V power source, this depends on which design cable you are using and the serial port of your laptop.

I got the cable from here. http://www.customefis.com/cableorder.html It just has a black and red wire coming out of it. I have the file 0D A217 Engine v1_0.zip File Size: 19.09 KB from moates and the 31v002a.ecu file off of Tunerpro site. I am connecting the red to the Pin "M" and the black to pin "A" on my ALDL. I'm also running a USB converter to my computer. It says it's connected, it's just not showing any data. Thanks for the help.

There was a problem with a driver file from tunerpro. I had the same thing happen to me. GO to mark's website and check out the faq. Download the fix. It's a problem for particular versions of windows.
