If not mistaken, the max engine rev for CVT is around 5750rpm only, but the meter can reach until 8k is really... not sure manual how much it can rev.

Fixed.

All talking about future proof for non sense.
The engine itself did able to reach at least 7k RPM (Well, the 1st batch Saga BLM and FL can reach 7k RPM), but due to CVT in used (started from Saga FLX), they decided to tuned down the max rev to 5750rpm.

As long as Punch CVT is in use for future Proton, i bet you hardly can see the needle pass beyond 6k rpm.

From ur statement, i bet ur is manual Iriz??

Is 'normal' for drive-by-wire Proton engine, due to the delay between pedal input and throttle output.

When u lift off the throttle pedal, due to the delay, the throttle body is still open, then u press clutch at this moment and the engine like suddenly become free load, so the RPM slightly rise.

Why I know? Becos this drive-by-wire 'delay feature' started since manual Saga BLM. Just surprise after 7 years they still remained this 'feature'.

Try test another way round: In free gear N, press your throttle and observe the engine sound and RPM rise, you will notice your engine will only rev up 0.5s after u press throttle.

Which variant u test drive? Manual or CVT? I bet u won't notice in CVT.

Then this sounds more like tachometer delay rather than drive-by-wire delay. But from what u mentioned when u release throttle and rpm rise, is definitely drive-by-wire delay.

The engine noise is tally with ur throttle input? By right is instant and zero delay, I think u need to test on that again.

For my understanding, this delay is caused by calculation take place in ECU after pedal position sensed before it send signal to throttle, is related to ECU micro processor speed and software calculation algorithm, i don't think any aftermarket throttle controller can solve it.

I wonder Iriz sales is facing a big blow again. So much hype before launch and up until now i never saw Iriz more than 3 times on road, but Axia is flooded the road adi. Anyway i stay in JB.

Don waste ur time to complain, SC won't solve dashboard creaks one. Especially ur case is creaks when hot and silent when cold, very difficult to catch just by drive one or two round by SC technician.
