Don't forget that in your US car, in un-modded condition, there is no situation where you have MANU lit up on the dash that the Power light will come on while driving. This is because manual mode is designed to cope with slippery conditions. It was not envisaged that Power shift map would be needed in slippery conditions. |
I have just checked the TCU program and can give a definitive answer.
On a JDM TCU, the logic goes like this:
1. If cruise is on, set normal mode and goto 5
2. If manual switch is on, set normal mode and goto 5
3. If power switch is on, set power mode and goto 5
4. Decide whether to use normal or power based on speed and throttle.
5. Exit
On a USDM, the logic goes like this:
1. If cruise is on, set normal mode and goto 5
2. If manual switch is on
and the stick is in 1,2,3, set normal mode and goto 5
3. If power switch is on, set power mode and goto 5
4. Decide whether to use normal or power based on speed and throttle.
5. Exit
In other words, on a JDM car, the manual switch overrides the power switch in every stick position. On a USDM car, it only overrides it in postions 1 2 and 3. I am surprised to see the manual and power mode on at the same time. If you have the car in D with the manual switch on and the power switch off, can you engage power by stomping the gas? It looks possible on a USDM car, but not on a JDM car.
