Myvi Gen3 chocking after install KKT 32 Compact

[fishboneinc]

Hi guys, I just installed a piggyback ECU KKT 32 compact on my MG3 with K20 plug coil. There're 3 modes for you to play: Normal Mode (Mode-1), Anti-lag Mode (Mode-2) and Launch Mode (Mode-3)

My car already modified with MaxRacing Air Intake, extractor and resonator plus muffler.

So when I switch to Mode-2 which can pop and bang during 4,000rpm, I will feel a little chocking, something like the fuel didn't come very smooth and causing
"coughing"on my car. I understand that during anti-lag period the car will chock is quite normal but now my car is chocking during idle at traffic light and picking up speed too. Like I put "D" and tekan brake at red traffic light, the rpm will suddenly jump from 750rpm to 1,100rpm then drop back to 750rpm within 0.2 seconds!

Then when using 2nd gear to picking up speed, at a certain RPM you will feel like someone pressing NOS for 0.1 second, your car will boost out a little then back to normal.

The technician who handle my car removed my air intake and change back to the stock on, but still LPPL same chocking.

Any of you facing this problem before? Any KKT 32 Pros here who can help me solve my problem?
Thanks in advance!

Is your Myvi turbocharged? If not, why want to map for anti lag??

Oh it's you ka... KKT32 Thai ECU. Hahaha.. welcome to ZTH.

I don't know any tuner who is familiar with KKT32 - can't advise. But judging from your explanation it sounds like there is a tuning issue. Or the KKT32 wasn't connected properly.

Who installed the thing? Go back to them to find out more I guess.

The installer should know better. This seems to be a problem of tuner themselves don't know what they are doing.
