Anyone have a copy of source for $0E that compiles that I could get? I would really appreciate it.

The hack on Moates won't compile that is for sure. I don't want to recreate the disassembly if someone already made one that compiles.

Thanks

 

The only one that assemble so far is the $0D. I set it up to assemble in the miniIDE assembler. The ASM11 included with it will assemble it w/o error, and Ive used it in the car w/o issue. Is there any reason you must use the $0E? All similar masks will run on the PCMs as they share the same hardware. The only real differences are in the memcals.

Edit: Is it due to the 4L80E in your sig? The codes can be made to assemble, but itll take at least 10 hours or so to format the whole thing. Doable if your patient. Basically, you have to clean up the tables and code, make sure everything thats not code is set as a comment, or deleted, and remove all unused labels. Leaving them in there will cause some issues with some assemble as they take up alot of memory.

 

Yah I need $0E becuase I am running a 4L80E. Heck if there is $85 or $31 that compiles, that would work too. 9Even though we couldn't get these to run on the ECM we are using along with how we had the wiring hooked up.)

Can you email the $0D to me so I can look at it? paul@nwstp.com

Playing with the idea of stripping out all the spark, fueling, etc. to just leave the code that runs the tranny. I am piggy backing a 4L80E ECM now with the 749 and was thinking it would just be easier if the second ecm didn't have all the code we aren't using in it. Think of it as a cheap alternative to a TCI transcontroller.

Thanks for the help..

 

Maybe not cheap in functions as I personally think the TCI controller is so simple it sucks. Maybe ok for a guy to install and go, but the control isn't great and the software I saw didn't even have force motor tables labeled.

But yes, as Paul said we are using it to control a 4l80e, the spark, fuel etc is worthless for our application.

I don't know assembly that much, wonder how hard to just strip the fuel/spark stuff and get just the tranny controls to assemble?

 

In actuality, it may be easier to add in the extra bits of code to enable the PCM to handle boost, so you could have one integrated solution. I wrote down all the math in the $0D hack, and it wouldnt be too terribly difficult to alter how the MAP is represented. Basically you could create a seperate MAP term for the fueling and spark and leave the rest of the code with a 0-100 kPa MAP term, or convert all of it. The PCM can also do batch and bank fire as well for MPFI systems with some mods to the memcal. See 'TBI guys, its time to update' thread on this board. There is a user here who is using TPI with this PCM. The $0D hack is also posted within that thread.

 

Thanks for the info on the post with the $OD source. I am looking to make this more of a stand alone ecm for the tranny since the $59 code being worked on already has Wbo2 Fueling in closed loop, a 16x32 fuel table (0 - 300kpa MAP and 400 - 6400 RPM range) plus a bunch of other enhancements. So I have that covered. Looking to just piggy back a trany ecm for now until we possible merg that into $59 if it is possible. (probably not since there aren't enough spare inputs on the 749). I am just a tester of $59 and not a coder so I guess this a good way for me to learn how to disassemble and code.

 

It would be doable to remove most of the spark/fuel code, but it would require that you have detailed knowlege of how the whole code fits together. Some things, like the MAP reads in the DRP and spark loops, are essential to the trans code as it uses those as well. It would probably be easier to just disable some of the error codes that arnt needed as the trans routine is fairly isolated from the spark and fuel routines. They'll still run, but wont have much effect on the trans code.

If you want to add code, though, youll have to remove other code and routines as the processing time in these is really tight. I added in MAF in place of MAP for the fueling, but this required removal of about a 1/4 of the code from the spark and fuel routines to free up some extra processing time. Even though I did this, some loops still overrun every now and then.

 

The PCM has alot of specialized hardware for the trans that wasnt on any previous ECM, so migrating over to the 7749 would be impossible. It would be possible, though, to adapt the $59 to the PCM at some point. All the hardware needed is there, its just a matter of adapting/merging the code.
