Query TCU from loggers

[west_minist]

Hi there!

I remember when the first loggers came out and were tested.

My question to you, are all the SSM port pins used?

I have a auto subaru and I noticed from the service files that the SSM plugs into the same port without any other modifications to read the TCM.

Do you know of any way that I can use those same 1st Gen loggers to query the TCU?

Any ideas why we do not see it respond in the auto mods or that wasn't tested?

I remember that by querying the ECU, you can get a string of hex that tells you what is supported. How do we know where to query to get that info?

Thanks in advance to everyone reply.
