Hi
I am a MZ3 owner from Thailand.
I have a couple of questions to discuss with you guys regarding the reprogramming Electronic Management System to fix problem related with engine going stall.
I happen to know that Mazda Malaysia has informed its customers to bring their mazda3s to have them updated. This was done to prevent the engine from choking or perhaps going stall at low rpm.
The situation in Thailand is no differ from Malaysia. However the Mazda Thailand has just started doing this (tuning the EMS) with their customers yesterday.
Since the users in Malaysia have been through this kind of situation before the Thais, so I would like to know if the reprogramming of EMS can really fix the problem?
It would be very kind of you If you could share with me any information that you think might benefit to all mz3 users.

Hi there.
I got recall for reprogramming of ECU. Honestly, no difference at all. Still need manual overwrite when at low RPM..
That is why I'm observing the car on highway, traffic and uphill roads.
a. Highway: No difference. Still felt the dragging of the engine, especially you accelerate harder (probably 2/5)
b. Heavy Traffic: No difference. Average speed is 20-30km/h so no comment
c. Uphill road: Still testing but first few slopes (around 15% slope), felt the GB did not shift to lower gear, even RPM at 2,000
