I have Mazda 6 2.l petrol 145/hp on 17 plate. Does anyone of you did increase power to skyactive engine and if yes what was the result? I was told this will improve fuel economy ( is it true)?
 
My brother has owned Mazda 6s for awhile - they are quite responsive to remapping, etc. and while true of any vehicle you really need someone who knows what they are doing - some of the biggest figures come from tunes which aren't very useful for either road or track use. I don't know about tunes for fuel economy but one of the more popular tunes for them significantly increases the performance off the line, at minimal change to fuel economy but doesn't change much else.

2L 145hp? Sounds like it's NA, therefore tuning it would be almost pointless. Put a turbo on it, then tune it

Sounds like OP is leaning more towards economy rather than performance - not something I know much about as anyone I know who has remapped a Mazda 6 has been looking to enhance performance.

They aren't entirely pointless to remap though as the factory tune tends to be very progressive power build which on the 2.0 IMO feels kind of gutless in the lower end of the range, they can easily be remapped to bring much more of a surge of power earlier.
 
Seems unlikely you would map for economy though, the manufacturer would have worked hard to get good economy numbers. I've had maps on turbo engines that suggested better economy, was nonsense ofc, just more boost pressure and different delivery curve.
 
With it being an NA and certainly not high bhp engine either I wouldn’t bother myself. Mazda would spent months/years developing that engine, running it in a test cell testing different calibrations.

We own a Mazda 6 petrol, not a skyactive, it’s certainly not powerful but returns a good mpg. From what I understand the skyactive version is better on bhp and fuel economy.

As many others have said, if it was turbocharged or supercharged that would be a different story.

Yes fuel economy is main thing especially price of petrol these days.
 
Real world gains will be 0, don't bother, you would be better off checking your tyre pressure more often
 
Thanks for your opinion guy's but I would like to find out from someone who actually did this and his point of view. There is little on net about that.
 
Always gains to be had with mapping if it’s done correctly ie by someone that knows what their doing on a dyno. Not a man in a van selling flash maps off his laptop.

The skyactive engines are also offered as a diesel 2l 145 bhp version which is what the OP may be refering to

In which case gains circa 50bhp increases with an additional lump of torque depending on how aggressive the mapper is

If it’s a petrol then there will be some small bhp gains nowhere near the above though but can be mapped to provide better throttle response and drive ability

Main goal is the fuel economy but better response this will be bonus.
 
I'd look into this. It's maybe the same engine used in the ND1 MX5. In that guise it has 162hp and responds well to a map, so the engine in the Mazda 6 may be 'de-tuned' out of the box, which a map could cure.

Wouldn't surprise me if there are decent gains to be had.

/Edit - found a couple of sites quoting ~180hp after the tune, which is similar to what the ND1 MX5 achieves.

That's was what I was wondering.

What does that tell you about how popular or worthwhile it is?

I always love people like this, don't know why they bother to ask for help...

Worst part is these people don't understand an engine is an engine, we don't need specific experience with your specific car with your specific engine, to give you the correct advice...

But you are clearly an expert, should ignore all of us, and got and sign up to a car forum...

So you mean tuner websites? They always quote higher figures, they want your business, take it you have never had a car mapped
