Just bought the Moats adapter and cable to connect my 85 to my laptop, but I'm still confused with what software I should run. The adapter I bought is a USB interface, and I can't seem to figure out how "WINALDL" will interface. This is my first attempt to enter the dark side of computer troubleshooting so I'd like suggestions for a easy to use/understand program.

It won't connect with WinALDL. Craig's adaptor is made for 8192 baud software, WinALDL is 160 baud. The 870 (1985) ECM is strictly 160 baud.
You need to make the WinALDL cable for that software, a simple 1 transistor and couple of resistors cable.
I can't answer your question exactly but I'll bet Craig will make it right if you have a cable problem. Have you tried data logging using Tunerpro RT. Neat program. Guess I am biased since it's the only one I can get to run.
I'm not "up" on tunerpro but I believe it is 8192 baud only, just like Craig's 85x ECM software.
WinALDL and Diacom are the only 160 bauds I know of. The cable for WinALDL is very simple to make, If you'd like I can make one for you possibly this weekend, I'm attempting to make a Diacom board & cable at the moment.
If you'd like a cable PM me and I can tell you of some of the options that I build into the cables I make (mostly for friends, etc).
You will need a laptop with a serial port though.
Thanks again Morley! I received a e-mail from Craig yesterday and he feels it should work in the 4800 mode.... I'll just have to check. How much you charge to build a serial cable? Trying to cover all the base's.
thanks again for the support everybody! My car is about to drive me knuts! It seems when it goes into closed loop, it won't accelerate, and even backfires if I try and push to hard. I hope once I figure out the software side, maybe I can record the problem and figure it out. It's not throwing any codes...

The cable would be free, 1 transistor 3 resistors.no biggie.
One thing I forgot to ask, did you have the 10K ohm resistor across pins A&B of your aldl when attempting to scan? If not, you need it there to get the ALDL to "talk" to the laptop.
Morley - Not sure it has the resistor since it's a sealed unit. Moates unit has a ADCL plug on one side, and a USB on the other.... I'm going to try again this weekend, after the Corvette show in Fort Worth! I'll let you know... Thanks for the offer on the cable, I'll let you know..
Haven't looked at craig's stuff for a long time, but I believe it is max232 based. If the circuit is done correctly there is no reason why a standard 232 based setup will not work on 160 baud as well as 8192....actually, all the way to 115,200 baud.

If it is based on the schematics on his site (and others) it is 8192 baud...according to his site and the others where the schematics are.
try mastach.com. I purchased a cable from them and it comes with an addition pickoff the the 10K option. I use mine on my 84 and winaldl. The only thing I have not found so far is a scanner that will let me save my data for review afterward. I do have schematics for the cable if you want to attempt to build it yourself. Let me know.....

Morley and others... Well I got WINALDL to work! Not sure I still understand what I'm looking for. Can somebody read my earlyer post on the problem I'm having, and give me a starting place? Also, I downloaded "TunerPro Rt" but I can't seem to get it to work. Do I need a differnt bin file for my 85? And if so, does anybody know where I can find the one I need? I'm really trying to learn this stuff, so please excuse my stupid questions..

Tunerpro and Craig's ECM software won't work with the 1985 ECM's (870's), they are 8192baud and the 870 ecm is 160 baud, Winaldl is about all there is that won't cost a fortune (diacom $800 plz)
I did a search for posts with your user name...didn't find anything about the problem you are referring to.
Oh dopey me...was looking for a thread....
Ok, while hooked to winaldl look at the gms/sec while at idle in closed loop. You should be seeing 7-12 gms/sec.
Next, look at the coolant temp and compare that to your dash gauge. They should be fairly close to each other (within 10-15 deg) If it is grossly different, replace the sensor located on the front of the intake manifold (the smaller of the 2 things on the front)
Start there and see where that gets you.
The only thing I have not found so far is a scanner that will let me save my data for review afterward.
There is another way to get the info you can use for tuning. FJO makes a WB O2 and controller that lets you log afr-rpm- and two other inputs, I use MAP and TPS you could also use TPS and MAF. These will give you just about everything you need for power tuning. You can also put the WB O2 in the place of the stock sensor and the FJO can convert the WB signal to a NB signal and you run that into the ecm. You can get software that logs it to a computer or a PDA and using the info you can get your table much better than any of the other full scanning software. Good power tuning requires a WB O2 analysis and no comercial software out there includes WB information. Total costs is about $400 but you get what you really need for tuning: Wide Band AFR, RPM and/or MAP/MAF on one log.
You do not get spark/timing but once you get a VE table close you can watch afr as you increase/decrease spark to get the spark right.

Ease Diagnostics makes a GM OBD1 scan tool that will scan ALL GM OBD1 vehicles (82 - 95 Vettes, GMC Trucks, etc.) with a standard OBD1 cable.

You are correct Morley. Ease OBD1 scan tools are $315 retail. Not cheap. For an owner of one OBD1 vehicle it probably isn't worth it. Especially if there are other free tools that will work. If you have a couple of GM OBD1 vehicles, then the ability to scan ANY of them is pretty handy. The Ease GM OBD1 tool will scan and report on the later C4s with the seperate Body & Chassis controllers which is pretty useful.
