new $EE tuning thing!

[steveo]

a lot of the functionality is based on information from you, looking forward to getting the V6 version working better with your help too.

requesting a slight edit on my name... close, but not quite.

also, I forgot to grab the libraries first and it took a few DLLs before realizing that, but this looks damn promising.... I might be able to get a few more people into playing with their 94-95 3100 W/L/N-bodies if they're able to play with their calibrations for basically the cost of an ALDL cable.

haha oops ill fix your name in the next version

so you think V6 guys will like this thing? i don't have a v6 ecm or any datasheets, so any data you can give me on how their mode4 stuff works, or any bugs i've made in the datastream conversions, let me know. many features are simply greyed out but obviously plan to add them as information comes my way..

was thinking about making an installer, but i really like having the libraries seperate, since they're huge and my program is small.

i think the big thing missing for deployment right now is update notification, since i make changes, bug fixes, and new features all the time, somehow i think people aren't going to check back for new versions frequently without being poked a bit...

[steveo]

robert, as you're big into V6 stuff, could you please provide me a spec on how mode 4 works on these v6 ecms? i can't seem to find a good one.

as well as any other tidbits you think might be useful?

does it use 19 blm cells? are they stored at a consistent memory location?

also if someone has a spare ecm they could donate to me to accelerate development, i know this forum doesn't have a lot of V6 guys, where's a good community to get my foot in the door?

I can probably find another unit here soon, I have another one that will control a 4l60E.

I just bought the winflash software and have been using it, but am keen to give this a try once it is a little further along on the v6 side of things.

[steveo]

flash write might be slow to get going on the v6 side but i will get it working eventally..flash read is already kinda working, i did that as a special project for kur4o, it reads a lot of unneccessary regions, and saves it as an lt1-like bin.

I can probably find another unit here soon, I have another one that will control a 4l60E.

i suppose any would do, i never really plan any transmission functions; i'd just plug it into a bench testing setup.

i really dont know a lot about the v6 ecms, i'd learn if there was one in front of me, but better yet i should buy a car with one, that'd get it going.

Steve, you use IDA? I can upload both halves of my disassembly, be easier to explain things that way. my P66 V6 ADX has some mode4 stuff in it already but I have more defined in the disassemblies than what I have in the ADX.

stuff I can answer off-hand: the T-side does primary communications, mode4 stuff is passed to E-side over SPI. E-side mode4 bytes are 360-366, T-side mode4 bytes are 34A-355. I've got a decent amount of both decoded.

BLM cells are located from 100-142 on E-side(an odd byte exists between the cell groupings, it might be an idle only cell?). 100-10F are Right/Rear O2 sensor with CCP active BLM cells(1-16), 111-120 is " .... " with no CCP, 122-131 is Left/Front O2 sensor with CCP active, 133-142 is " ...... " with no CCP.
