I have tested it in my CRX SI 91 with CIVIC SI 90 Auto ECU(pm6) and it work perfectly.

This is why its not necessary to remove anything in the Auto Ecu to Run with Manual transmission.

The obd0 AUTO ECU its nice for obd0 VTEC project. Cause the A8 pin use on the auto ecu its the same pin use on the obd0 VTEC ECU for the VTEC Solenoid.

What you need to do: With obd0 ECU, you only need to solder a wire with 220 ohm resistor between A2(ecu gnd) and A8(vtec solenoid or auto lookup).

The 220 ohm resistor Fake Auto Lockup Solenoid.

The Ecu dont see anything!

Its possible to put a switch between A2 and A8 to switch Auto to Manual mod or VTEC to Non-VTEC mod.

See the attachements below to know more about what i explain

• A2 WIRE:
  

• A8 pin with brassing:
  

• 220 ohm resistor:
  

• Mod Switch with the 2 wires:
  

• the 2 wires solder:
  

• outside view:
  

• side view:
