Have 92 Accord with 1.8 VTEC. The Installed Engine is From 98 Accord. The transmission is the original which came with 92 accord. This transmission is operated by Kick Down cable and does not have any Main Shaft or Counter Shaft Sensors.

During Swap My Car was Given ODB2B Engine hence ECU was replaced. As car had its on TCU so transmission kept working great and is still working flawlessly.

The ECU Installed expects to have Main Shaft and Counter Shaft Speed Sensor attached where as I do not have them. I was thinking that why not install a Manual ECU so that VTEC should work and As existing ECU is not getting any signal so on pressing throttle in D ECU thinks of Slipping.

Would Manual ECU work in my current Setup?

Your '92 transmission is not operated by an ECU. The kick down cable and in-built governor decide the change points of the transmission, using line and governor pressures.

The engine that you have now had fitted would come under OBD2 because of its time of production,'98. The variable valve operation would use signals from a later transmission, which you do not have fitted, as part of OBD2 control.

You need to have '92 engine and transmission, or, '98 engine and transmission to have a single ECU controlling the installation.

The '92 ECU will have inputs, sensors, wiring and software for the '92 set-up. The '98 ECU will have inputs, sensors, wiring and software for the '98 set-up. There will always be differences between the two and they will always be incompatable.
