Vida CEM swapping

these days I will switch the program to English and upload it to github, I have to enable/create user Connection String modification, now it is hard coded and useless because it is related only to my computer.
I don't know where Luke is, it was very good that he was here,
Before I started coding, I tried to contact him by private message, but I was too young on the forum and I didn't have the opportunity to contact anyone. so after I successfully contacted vtl trough gmai things became clear.
I will not write novels anymore, dirtying this useful topic, in the future only concrete, useful things from me
I'll need your help, a diagram of how to connect Teensy4.0 and Bosch CF160, once they arrive

The Bosch CF160 is straight forward. Pin to pin no extra components. See attached file.

thank you,

I pinged T5Luke via email a month ago or so, he didn't reply. Hope, he's doing well, just no free time.

Ignore reference to U3. I forgot to delete it when editing this one from another build version. Or you can download the cleaned up schematic from github. You can find it in my fork or VTL's after he does a merge.

Anybody figured out how to power up a CEM-B ( 1999 - 2004 P2s ) for bench testing?
I have 30+ ( V-Battery ) to E:3 & E:6. E:1 is grounded, no current draw.

Tired applying 30+ to the Ignition switch pins B:1 ( S ), B:2 ( X ) & B:3 ( 15 ) and still no current draw.

Missing something ... Is there a back door for the 30+ ? Hidden ground ?

It goes into power-saving mode quickly, you need to send it into programming mode quickly. I usually power it on only after the cracker started sending the "go to prog mode" messages.

i'm looking at .bin i read last week ..
is it possible that pin is 0 0 0 0 0 0?
i'm not sure if anyone touched CEM before me.
and I'm not sure if I'm at the right address 0x6000?

I am not getting any current for any length of time. Monitored the current as I connected the bench power supply .. nothing.
What pins did you use to power the CEM? Trying to sort out if the CEM is dead or I am missing something.
