timing chain

Hey team, I'm a new Mazdaspeed 3 owner from New Zealand. My car is a JDM import so is a Mazdaspeed Axela (the JDM name of a Mazda 3). I joined up to get some info on the different things I need done with my car. I've already found some awesome information here, so I'm glad to be a part of the...

So I had a quick question due to my ignorance on the subject. If I upgrade my Turbo from my stock one, do I need to flash my ECU? I recently replaced my timing chain and VVT, Cam and crank position sensors, rebuilt my high pressure fuel pump, replaced injectors and fuel rail. I am beyond certain...

Alright so I know there’s a few threads on here about this but I haven’t seen anybody with my direct circumstance. Long post incoming… Permanent Code P0012 I have a fresh built engine that had been built by a reputable shop. Mazda OEM VVT kit was installed at the time of build. I’m...
