capture/repeat data ?

[Sam]

Hi, here is the email I sent to elm.....
--------------------------------------------------------------------------

I'm very interested in purchasing your products, mainly to start with, the elm322.
My question is, with your product can I record a specific section of data from the vehicle, for example, window down, and then be able to re-transmit that section of data back to the vehicle to perform the window down function ?

Thank you for any information on this

Here is what elm says...

Hello:
Thank you for your interest in our products. Sorry, but our OBD ICs can not do that for you.

Maybe I didn't word things right to them or do their chips communicate with the ecm on something other than class II ? What do you think about this ?

That is not the original intention of the device; so he is correct. However I know your application and I think it will work. I also know Jim (J Nagy) very well; he created the chips and is the owner of the company. He and I are in contact quite a bit.

I think the issue is how the email reads. Most times window up/down is electrical; not data. In your case its data, assuming it is VPW this device should work great.

Remember, worst case, if it doesn't work and you have diagnostics device for your vehicle.

I emailed Jim some of the back-story for clarification. He likes to hear about new uses for his chips.

Yeah, I think you're right about the wording.
And that's true as for the worst case, I'd like to have that anyway.

Thanks and, do you have a 2500 HD by chance?

[DynamoBen]

What is a 2500 HD?

[Sam]

A 2500 HD is a 3/4 ton heavy duty chevy truck.
The reason I asked is I read on another forum about allot of class II details written by a very smart guy named Ben.(who has a 2500 HD)

Nevermind, I'll stick to what we're doing here.

Thanks

[DynamoBen]

Nope not me; although Ben's do tend to be a smart bunch.

Do you mind posting the location of the info you are talking about? Then I can study up a bit.

[Sam]

Hi,
I'll find the post and repost here. I've placed my order for the elm chip and will be building the pcb for it while it's on the way.

Also here is what I recorded from the data bus using "serial file" from fogsoft and the serial input on my laptop.... this was door unlock button press...turning the ignition on produced a tremendous amount of data,(not posted here ofcourse)each line here actually showed up as one continuous line,so here each line picks up after the previous one...

What do you think, should it look like this?
EDIT: I just noticed that the original file on the old laptop has allot of "black boxes" in the data but when I copied/pasted so I could email it to this computer the boxes were replaced by various characters ??? mostly the up/down arrows and >>> I even sent as an attatchment and no black boxes.

Thanks allot
