Mind to share the tuner shop? Afraid go to non experience tuner.

PM me. I give u his contact.

Does fuel consumption increase after tuning as I understand Mazda purposely tune the gearbox to be "dumb" so to save more fuel.?

im a heavy footer so i cant comment on that.
my friends car can go 650-700km on single tank (RPM never goes beyond 3500). mine goes 500km cuz i like to overtake (sometimes go 140kmh, or maybe cuz use semi-syn oil)

overall if u can tolerate the normal slow pick up, then no need tune i guess.
but if your driving method is floor down a bit to skip the turtle pick up, then go for ECU remap.
yep Mazda purposely tune the gearbox to be below 1500rpm.
the ECU remap also remove the engine jitter when in traffic jam, can off i-stop, speed autolock (going above 20kmh)

Suspension is good and superb imo. The noise from suspension when it's wet is a known issue, some info i remember from mazda 6 group i read before is that mazda engineer came to malaysia and scratch their head seeing this. I lived in tokyo before and with the amount of drops everytime it rains there no suprise this caught them in unexpected way when it comes to malaysia heavy rain. And then mazda 6 in early days are all CBU units so there's that.

Other than that, i would still recommend second hand purchase if the car is maintained well

I think just do the walnut blast, no need to do that seafoam anymore.

u did before ah ??
what effect does cleaning the back of the valve can do ??

Not yet but I know that should clean the valves perfectly. Effect is depending on how bad the carbon build up already. If bad then your car power and fuel efficiency should be more improved because there'll be more air that can flow inside like new again.

Alright, if you got find good contact pls share.

share with me as well if able to find a person able to do walnut blasting. Found one but only does continental cars specifically. Japs no layan. :-(

i found this, never visit them before. they got walnut shell blasting, EGR cleaning services as well.
looks like they service a lot of mazda 6 and cx5

let me know if u done it ya, thanks

can do these maintenance if reaching 100,000km
1. AC compressor service
2. engine decarbonizing + intake valve + EGR valve (do all these the car feels like new d, clear piston, exhaust, intake)
3. transmission filter FZ0121500, strainer they called it
4. engine mounting
5. spark plugs (if not mistaken is rated at 80,000km)

Yup that's the one I saw too, seems quite specialist in Mazda too.

injection valve cleaning without walnut blasting method......

near to 40,000km already super dirty

I see. Did a call to them and they do offer walnut blasting. They even did piston decarbonizing. Saw their fb that they did quite alot mazda 6. Im planning to bring my car for walnut blast next up 90,000km. Perhaps change atf filter as well and spark plug change. Will let you know the results after done. Do let me know as well if you done it first.

remember do ECU remap after nice service.
u will feel like driving different car. step a bit it's already 100+, no more sluggish feeling anymore.
just now on NKVE behind a beemer was thinking why he's going so slow. see my meter it's already 140+kmh. dint realize it until see meter

the ATF filter need to change as usually when it's due warranty is long over d.
outside mechanics might dont know service interval as it's not done so frequent (80,000km is 3-4years)

let me know when you're going

Just careful on gearbox

Already one reported case gearbox start slipping after oil change , before that no issues.

sure. I will go maybe few more months once i clock 90k as currently just serviced my car. see if you want to go along :-) is in subang airport there. perhaps can pm me your contact and keep in touch ya.

consulted my friend (the one with 200,000km on it) what thing he use to service the car cuz his one tank can go 700km. mine only 550km.

so conclusion is a lot of things (my engine should be super dirty with oil deposits, so the whole car is not responsive, and not so fuel efficient)
this service interval i switched to Liqui Moly full synthetic + engine flush + additive (to reduce friction)

this is what i did with it, first spray Seafoam valve cleaner into intake and rev everything to clear valve.
then drive to workshop to ask them do engine flushing.

OLD engine oil (7000km) after adding flush and running it for 10minutes. like KOPI-O



then because i watched some videos that do flushing on cars that never done it before (run 100,000km never flush) they had to flush - drain - add new cheapo oil to run 2nd round (run 10-15min) then drain. THEN only add in LIQUI MOLY.
Basically DRAIN THE OIL TWICE if not the new oil added will be instantly dirty !!

this is the sacrificial cheapo 4L engine oil (new engine oil just run for 10min) that i added in after draining the oil.
pour new oil in immediately turn dark, dirty like teh O.




after that add in LIQUI MOLY 5w/30 and additive.
now the car is very responsive, can always feel the acceleration even step on the pedal a bit !!!!!

Steps
1. seafoam clean intake valve
2. pour in engine flush and run for a while
3. drain 3month old oil
4. pour in new sacrificial engine oil and run for 10min
5. drain 15min new oil
6. pour in new LIQUI MOLY oil and additive (MOS2), change oil filter.

so much better response. step a bit power immediately come

Many types of cleaning can do. Fuel additive, intake valve, engine oil additive (these are without opening engine top cover)

Anyone owned a 2.2Diesel here? Mind to share ur experience?

I was stuck in btw 2.2D or 2.5NA

Very helpful to existing/coming m6 skyactiv owners. I'm getting mine soon and will contribute some hopefully useful post here tks everyone here😊
