Not TCU meh?

i thought that is ECU = electronic control unit ??

oh man......my mind is gettin'messed up...
LOL'ed meself...

yeah its TCU and ECU......

I guess TCU should be Tranmission Control/Computer Unit. Meanwhile ECU is Engine/Eletronic Control/Computer Unit.

That said, I take it as the Gen2 sedan only have updated TCU (as written on the 'spec'). So no CPS or VIM yet.

All this thing is confusing me, what tcu icu or...

What the heck the do? What is the different?

they reprogramme the engine so that it will run more smoothly and maybe give it a bit more power output.

I thought this sedan only have updated TCU so it will have correct gear ratio so the sedan wont have low end torque problem like in hatchback. No new or updated ECU involve.

wow...this car is suppose to hv more legroom and boot room compared to the waja??

this is definitely something i hv to see

TCU i suspect not to control gear ratio, you can't simply change gear ratio in a car without changing the hardware(gear). Since it will be implimented into the auto's and manual's according to PE online customer service, i would assume that it has nothing to do with the gearbox, it will something to do with variable intake manifold supplied by Robert Bosch.

TCU=VIM.....wild guess

I read somewhere about TCU and low end torque.
They re-tune back the gear. Not using the same like hatchback.

If TCU is to improve the transmission system then it would only apply to auto model right?

TCU=Torque Curve Upgrade
it improves torque curve of the engine so that it does not feel underpower in lower rev.

How do Proton improve the Torque Curve Upgrade? Do they change or add in any new part?

no, it's transmission control unit. it works together with the ECU for optimal shifting in order for optimum performance and FC.

ICU = Intensive Care Unit

TCU can be stand for Traction Control unit. Lovely if they can fit this in a Proton.

no.... traction control is usually labelled as TCS, that it traction control system. most of the time the function is built in the ecu, not an independent control unit.

The TCU and ECU all went into the ICU....Ha! ha!!!!

So will they fit the Gen2 hatchback with the new TCU thingy as well?
