Yep, that's the one. Thanks!!!
I already found a very similar program and looked at the BIN for the Caprice police cruiser. The Mask ID is different. It is supposed to be 61 (I think) but it was something different. I also found the bit for VATS Enable. I am still looking for the transmission control options to disable the auto tranny stuff. Any help there would be great!
Thanks again!!!

I'm pretty sure you don't need to do anything with the TCC stuff. The only reason I can think of for changing it to a manual trans option is that some code (not sure about yours) will use the high gear input, but even then, I think that's only for TCC operation.

 

Thanks for the replies guys!
Here's what I have done so far...
1.) Downloaded TunerPro RT
2.) Downloaded $61 ECU file
3.) Looked at ANLU (cop car) .bin: changed VATS Enable to DISABLED, set EGR Enable Temp to 0C
4.) Saved .bin
Now I need to burn it to a PROM and start looking at how it runs the engine (bored out AMC 360 with really nice valves and port/polish/gasket match job). I am thinking that the ANLU bin fuel and spark tables should provide at least a good starting point for the engine. Once I get the ALDL connector for my computer, I can start tweaking things a little.
I didn't screw with any of the TCC controls. Should I set any of the other parameters to a different setting for initial start-up of my AMC-GM engine?

 

This is probably a stupid question...
Can I use the 7747 datastream definition for a 8746 ECU? I can't seem to find a datastream definition file for my ECU. Does anyone have one?

 

If you are referring to the ALDL datastream there is only one location that is different, x-cnts gets IAT instead. If you intend to modify the ALDL locations in the bin then no, they are in different locations within the bin between the '747 & '8746.

The is a hac of the '8746 around. . .

Cool...I'll have to find that hac. As of right now, I think I can do this with the TunerPro RT software. Maybe I could go into the source code for the 747 and tweak it to switch the locations. Does that sound reasonable?

 

I'm lost.

RBob.

 

That makes two of us. I can't figure out if he's calling and ECM an ECU or is looking for .ecu file, but that doesn't have anything to do with the ALDL datastream, so I have no idea what he's trying accomplish.

 

Sorry...typo. I meant ECM not ECU. I got too used to calling it an ECU when I had the (ugh) Holley ProJection system. Many apologies. I know I am newbie and need guidance.
I can't figure out if I need this "datastream" thing or not to hook into the ALDL connection when the engine is running. If I don't need it, great.
What am I trying to accomplish? I am trying to retrofit a 1990 TBI into a 1980 Jeep with a 1979-model engine...and make it all run right. I had the Holley ProJection system...very troublesome to say the least. At first it was great, then the problems started mounting. It smoked one ECU/ECM, then another got stolen, then the replacement for the stolen one was bad right out of the box. I finally saw the light and went with a GM system. Now I gotta figure out how to make it all work. Wiring is simple. Tuning isn't.
Thanks guys...please bear with me until my newness wears off.

 

If I understand correctly you want to scan the ALDL datastream. To do that get WinALDL and use the definition file for the '8746. I believe it comes with the WinALDL program. This is a different tool then the BIN editor utilities and a diferent definition file then is used with the BIN editor utilities.

WinALDL runs on a PC, laptop or desktop. Has dat alogging and display capabilities plus tuning analysis.

RBob.

 

That's it....I have WinALDL already. I have not had the opportunity to use it yet. I am hoping that I can make it log/graph datastreams. The TunerPro RT seems to have the capability to show real-time graphs of ALDL data. Will WinALDL do this?

 

I think that WinALDL can graph the data, but don't quote me on that.

Hopefully someone that is more familar with WinALDL can answer.

RBob.

 

the limits of the version of winaldl that i have can only generate tables like blm, int, knock counts, etc. No graphing capabilities to my knowlege. Jsut pretty much captures teh data to hardisk (if you want) and displays current values. youll ahve to use excell to generate graphs.

 

So WINALDL is kind of limited in what it can do...bit it is functional. Good. That's what I have.
I finished a lot of wiring this weekend and managed to get everything in the right place...except for one wire. On the wiring diagram, the wire says "To Crank Fuse." Is this wire simply sending the ECM a signal that the engine is being cranked, or does it physically send power to the starter solenoid?

 

I wouldn't say that WinALDL is limited in what it can do. It provides the necessary data to determine what changes need to be made. All a graph of this data is, is eye-candy.... you still need the actual data points.

The "crank to fuse" wire just lets the ECM know that the engine is being cranked.

 

Thank you. I kinda thought that was what it did, but I wanted to be sure so that I wouldn't smoke an expen$ive ECM by putting that wire to the wrong place. I am putting this system in a Jeep CJ7 (1980 model). Trying to decipher the wiring diagrams and make it all work is rather difficult when going from a GM wiring diagram to a wiring system that is a hybrid of GM and Ford with a few twists thrown in for good measure.

 

Tell me about it... I have a complete system running on and International Harvester 345 V8. I had to modify the IH distributor with parts from a Ford distributor and remote mount the HEI module. It's sweet when you can take a old engine forward in time a couple decades.

 

Agreed. That Harvester engine is a great block. Too bad they quit making engines like that one...and the AMC 360.
The power and driveability gains that are realized when going from a carb on one of these engines are almost unbelievable. The AMC 360 really got a wake up call with the Holley system...and that system is crap in comparison to something that can take full advantage of the benefits that a TRUE EFI system has to offer. The Holley system was a real PITA to keep tuned. It required constant attention to keep the AFR properly adjusted and it did not like to hold a constant idle and TPS setting.
