AT lockup Torque Converter and TCM?

This got me thinking allot for days now.

I'm trying to learn what is the difference and how it works between the Lockup Converter between OBD1 and OBD2. How does it function with the ECU and TCM. The reason I'm asking, to see if it's possible to run Hondata S300 to control the transmission. I know it's been done on a 1995 OBD1 Automatic Integra. Trying to figure if it's possible on a OBD2 jumped to a OBD1 JDM AT P30 ECU and retain the factory TCM. I know Moates Demon works but the Demon 1 (for JDM ECU) is in no longer in production.

If any one has a wiring diagram schematic. Please post it. I can get a better understanding on how everything works.

About time I can now apply for Historic Tags for my GS/VTEC Automatic and no more SMOG

For anyone with a OBD2 Automatic there is hope.

From a shop that I was talking to
"This is one heck of a build! I am impressed. Generally these kind of builds require 2 ECU's one to run the engine and one to run the transmission. The inputs can be fed into both ECU's from the necessary sensors like the MAP/TPS etc. That would be your best bet.

I had a 2001 Honda Stream AWD K20 that3 I ended up in the same situation, dual ECUs. Its not ideal, but it does work,

Hope that helps "
