Damn it! Is there any 160 baud ECU that use the same harness as the '7730 ?

Nope.

The '7747 would be the most popular to be used with something like this.

The only other one that might have a following is the '7148 that is in the old Turbo Regals and Grand Nationals (also 1989 TTA).

So I would basically need this: http://www.ebay.com/itm/1987-92-CHEV...-/390647507497

Meh, I guess I will wait :P

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.

[3400tZ]

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,

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.

[EagleMark]

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.

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
