Has anyone tried playing with the "Engine Torque Control Signal" on the TCU? There's only two possible ways to engage power mode as it were to normally be engaged, one being this signal wire, and the other the Throttle Sensor wire .......I already tried to throttle sensor. .......but how about engine torque control?

Going by alldata, it shows this wire will have 4.5-5V with the throttle closed, and then 0.7-1.7 with the throttle open (WOT) ........maybe I'll try playing with this wire next.

It has to be this wire! I'm definitely doin it at work tomorrow....checking the behavior of Black with a Yellow and Light Green with a Yellow on the TCU when the power light comes on

Any confirmation on the JDM TCU?

Off subject, but I like how the USDM ECU wiring diagram labels terminal 20 on connector B62... "Inertia resonance supercharging control"

Sweet yo! I gots me a super-duper charger!

I did some Google searching for a JDM wiring diagram, but I couldn't find anything.

The engine torque control seems like a good plan, though. It certainly sounds like you know what you're talking about (much more than I do, anyway), so check it out! This could be it!

the engine torque control wire is what cuts power when the transmission wants to shift. I don't think you want that wire.

The place to look (I think) would be to put some kind of circuit to the TPS sensor wire. This as you know varies from 0.5 to 5 volts and is used by the TCU to figure out how agressive you want to drive.

I have no idea how to design it, but you might want something that with a flip of a switch changed the signal from 0.5-5.0 V to 2.5-5.0V. Keep in mind the TCU (to my knowledge) does not learn like the ECU does, so all it would think is you're always in somewhat of a hurry and sometimes still go to WOT.
