WOOHOO finally and OBD1 blue tooth reader. I got the OBDII for my other cars already, just need someone to write a program to read it with Andriod software now.
TunerPro RT allows you to see the inputs and outputs of the ECM in real time on your laptop. You can also save and play back the data.
By default TunerPro RT gives the output in numeric format.
You can also if you wish use TunerPro RT and make a dash to show whatever elements you wish.
TunerPro RT is downloadable at http://tunerpro.net Tunerpro RT is free to download and runs with a 10 second nag screen. If you wish you can purchase a TunerPro license and avoid the 10 second nag screen.
Along with TunerPro RT, you need some way to connect to the ALDL port of your car. I make an ALDL to USB cable - http://reddevilriver.com/aldl.html
Due to demand I now also make this bluetooth version to connect to the ALDL port of your car. You need a laptop that supports bluetooth to do this. Once connected by bluetooth, the cable works just like the wired version.
Design note - There are now two LEDs on the device. One (red or green) for power and one (blue) to show the paired bluetooth connection.
Also - The cable is designed to be powered by either ALDL Pins G or L. G is the fuel pump test port, so that allows it to be powered anytime the engine is running. If you wish to have it powered anytime the key is on, a wire with the correct terminal is included for you to add to your cars ALDL pin L position. Yes, the two power inputs are isolated to prevent back feeding of power from one to the other.

I'm in, send us the link. Especially if it allows to "sniff" data while the [b]car is running normally[/b (i.e.: timing advance still works, not in diagnostic mode)
The ECM's programming dictates what mode it needs to be in to spit out the ALDL data. Here is a discussion of what happens with the stock Fiero ECM when it is in diagnostic mode.
Most, but not all 8192 pin M ECMs send data by the scanner sending a 'data request' on the data line and the ECM spitting back the information. The 7730, 3.8 OBD1, and 4.9 ECMs operate this way.
For these ECMs no 10K resistor is needed on pins A - B to 'put the ECM in ALDL mode". Note also that ALDL mode is not the same as the diagnostic mode that is activated by shorting pin A - B.
Many late OBD1 ECMs drop the wire in pin B all together. Any 94 - 95 vehicle that is OBD1, but was equipped with the 16 pin OBD2 type connector doesn't have a "Pin B".
So correct your 4.9 will not be in either ALDL mode or diagnostic mode.
Sorry I have not read the entire thread, but do you have one of these ready to ship out? Reason I ask is I am in Oregon for the next 2 weeks, then back to Canada for an unknown time. I am going to need one for use with my 88GT to do some troubleshooting and will it for my 4.9 when I get back to driving it.

It was be awesome to have an android app to go with one of these. Have the bluetooth adapter always on with the key, buy a cheaper tablet, mount it in the dash and have any realtime data you want displayed. Sounds amazing to me.
You can do this easily with an obd2 car and the app "torque" but it would be awesome for obd1 too. I would gladly pay for the bluetooth/app combo and may just get the bluetooth cable simply because it would be easier than taking out the console. Great Product
Is the data transfer rate from the OBD1 ECM to the laptop or Android phone the same whether you use a USB to ALDL cable, or the bluetooth to ALDL? ie. is the ECM the slowest link in the chain?
