could go full-banana and get a '7165, which i THINK is the only ECM that did both 160 and 8192. it's actually pretty "easy" to make any ECM do 160 baud communications though.... thank GM's engineers for setting up a 160Hz loop for that one.

Yeah, that could be an option as well. :) I guess I need to get the ball rolling with this app and then I can spend some more money on test equipment.

Oh, and some random app progress, I just added a G-force indicator (as well as data logging G-force), sweet!

I've got a 8062 which is 160 Baud $4E you can have and I'll even pay shipping. But only one pigtail... the other plug has no wires... if you want it PM me your address.

[3400tZ]

No wire at all on the other plug ? I guess I can add some back in there ? I'm probably interested :D

[EagleMark]

Maybe someone has the large plug with pigtails? I have the small plug with pigtails...

[3400tZ]

PM sent :)

Which plug do you need? I have both 7747 plugs with no wires, and a pile of wires with pins that came out of them. But not sure if thats what you need.
I also have a test bench I can test 7427, 7727, and 7730 ecm's on, but no 7747.

3400tz,

I just thought of something that you may or may not be looking at in your coding..

I use tunerpro on my 1990 ZR-1, in the initial connection I have to send a batch of messages to get the CCM and EBCM to silence prior to sending/receiving data. I am hoping you are adding the functionality to your Android code, Also on exit of the log it does the reverse and removes the silence..

if oyu needd to look at my ADX you can find it here

but this is something that some of us will need to keep everything connected and logging correctly..

I think I am at page 6 now :)

[3400tZ]

Mark, awesome, you're right, I can probably apply something very similar.

Jeff, I didn't know about the "connectcmd" thing in ADX file so the app currently doesn't support that yet. It doesn't seems too hard to support at all tho, so I will take a look at it in a near future! That's a lot of juggling you have to do to get that ECM to connect tho :O

Btw, mikew sent me a 160 baud ECM today (AWESOME!). I guess I will receive it in 2 weeks or something. I ordered a bunch of DB37 connectors to build test harness if I end up getting more ECM as well.

You'll have to get those connection commands for the Lt4 corvette and all LT1 cars... may be more and also needed if it will ever do OBDII ADX files.

[-=Jeff=-]

I need to check my USB cable and if it is FTDI I can test the connectcmd for you when you get that far, otherwise I will order the Bluetooth device. My car has the PITA connection routine

[-=Jeff=-]

to add.. connectcmd I have in the posted ADX works perfect on my Corvette and it should be the same for the obd1 Lt1 cars as well

Yeah the connectcmd thing is to silence chatter. Its not really needed for on bench comms, but in car, depending on the car, the aldl bus can get pretty busy between the bcm, abs, radio, dash, etc etc. Theres some scope traces of the typical data on the bus on the aussie VT commodores that might help you here. The trick is getting the disable chatter in the gap. http://pcmhacking.net/forums/viewtop...p=27761#p27761
