same dyno and mods would be great!

i might try and get my car on the rollers this week sometime :)

Ive been through a couple of tanks now since the reflash.

the last tank consisted of the Club breakfast run. It was a spirited run with plenty of WOT happening.

Checked my Scangauge this morning before i filled up and it returned 8.3L/100Kms

im getting an extra 75-100kms out of a tank of fuel...its a win win...more power and better fuel consumption :)

Serious? That is seriously win win and very convincing! Thought it will stunt fuel economy.

Yeah i think that is pretty good, i'm not too good at maths, but by my workings, i'm guessing, you will have paid for the flash by fuel cost savings after you have dríven about 4000km, best scenario maybe 2500km. ! :shock: (maybe my maths really is that bad?) Anyhow the performance benefit is worth it right!

you've changed the exhaust and Headers and the facebook pages has again shown a car with similar mods. I'd be surprised if you didn't see a performance increase over the stock tune.

So where is the stock vs stock results, not just the Dyno but fuel consumption rates as well.

what facebook pages??

havent had it on the Dyno yet. Chris Gough says around 10-13 KW increase at the wheels

fuel consumption was mentioned a few posts ago....still returning 8.3-.8.4 per 100km

Ahh I'm with you now...haha

Not sure about the stock vs stock with flash results

Maybe contact Chris from mx5racing (where I got my flash done) he might have some answeres

The dyno from Moto-East is a bit sneaky with their choice of 12hp number :wink: . Max power was actually only up 8.4hp. So that's an extra 6kW max power at the wheels - doesn't sound quite so impressive when you put it that way. :lol: But fair enough, there's a substantial improvement in area under the curve, about 7-8% across the rev range ... with header & exhaust.

Would definitely be nice to see some before/after dyno for stock NCs. 8)

Hey guys I'm new to the site. I've just had a new pod filter with extractors all the way back to the exhaust fitted and have been looking for a couple of weeks to find a person to flash tune my nc. I've only been able to find 2 people in southeast Queensland who can do the job and the cheapest I'm looking at is $1210. Is it worth putting an icu chip in or should I wait until I supercharge it to really play with the computer?

Get in contact with mx5 plus. They are a site sponsor down at the bottom of this page.

They will do reflashes

NO! They are just smoke and mirror stuff.

A proper tune involves a number of things.

First up your tuner must have the software to modify the Mazda ECU, EcuTek was the system used to modify mine. Personally I wouldn’t go anywhere near a tuner who hasn’t worked on a NC before.

The tuner should save your standard tune into his system, just encase you require it to be reloaded at some later stage, ie should you go back to a standard exhaust system.

Then if he’s done a few NC’s previously he should have a base map with a tune for the headers that he can download into your ECU.

After the download it’s onto the dyno where they will do a few pulls to establish the output and to look at the air fuel ratio through the rev range. After this the tuner will modify the AFR where it is required and then download this new file and run it on the dyno again to see the result. Following this or maybe in conjunction with the AFR changes, he will look at the timing, maybe play with that a little and then do another download to your ECU, do another dyno run and check the final output.

As for the cost, remember you are paying for a licence for the tuning software, which isn’t cheap. Then you have the hours the tuner spends working on your tune and the dyno usage, so it doesn’t take long to start racking up the dollars.

So how much will you gain power wise? It varies car to car but probably about 4 - 5 kW.

When you say you fitted a pod filter, if it’s under the bonnet you have lost power, if it’s a Mazdaspeed / AEG CAI or similar you may only get 0.5kW improvement on the stock system. I would be very careful with these CAI's because with the low intake height you can suck water and get hydrolock.
