Auto or Manual?

I'm using auto Gen-2 , year 2004 spec.
I cant say much bout manual, but from what I know based on auto gearbox concept:

When I was rev-ing high (above 4k rpm, which is typical if I'm overtaking in highway, or "flying" down a slope ;do remember that gen2's auto has auto-shift down concept) I will get the following scenario:

When I start to slow down or stop (traffic light, toll booths), my RPM will remain high, and it will then slowly drop.

This is because somehow (not familiar with the concept), the engine will "cool itself down" and "refuse" to drop the RPM directly. Maybe it is controlled by ECU or maybe it is the auto gearbox

But it normally happen after a high rev, not while I am stationary or <3k constant RPM .

That is downshifting ... and to be exact, cheating downshift ECU calculations

If you read TS's post, it is more toward upshifting (high RPM when driver shift up , 1-to-2, or 2-to-3)

Actually, it could have been caused by ECU ... Campro is an high-rev engine, so I wont be surprise if the ECU rev the engine to maintains the powerband when driver manually shift-up (when there is not enough power during shifting)

Cant help very much as I'm on auto mode . zzz

One possible alternative is to send to PSC.

Ask them to plug the reader to ECU, then take a test drive.

If the RPM climbs instead during changing of gear, ECU might be able to show some insights to the fuel-air-mixture, O2 reading etc ..

Send to proton .Ask them to plug in the reader and find the error code.
Then from the error code, they would know what the problem is. You can also request for the error code meaning from them and repair outside.
Not many outside shop have the ECU reader and thus, wont be able to help. Normally they would use the "trial-and-error" style.

Who reset the ECU for your car? proton side or outside shop? If outside shop, good luck. If Proton, you can go back and get the report of the previous service (error code).

Oh yeah... forgot bout that method..

The thing I wanted to inform is that by reset-ing ECU, the error code and log is deleted. Thus, it become harder to find the root cause of the problem.
