New NC map

[Charlie Brown]

Easily done but it's doubtful the Mazda dealer will do it.

In 2003 my NB8C along all the other NBs of that period suffered clutch shudder. The easy fix was to install the SE clutch. But no, Mr Mazda wouldn't do it. Two clutches later under warranty the problem was fixed.

If Mazda won't do it, see Chris (Targa Racing) or Daniel (Deckspeed) and get them to do the tune.

If you ask a dealer, they'll probably do it along with any M-MDS update they need to do. IF not, just buy one of those plug and play accellerator thingos that do the same job off ebay or any performance shop.

No DON'T do this.

First up, do you really need this upgrade and if so, why? I doubt that you will notice any difference in normal day to day driving.

So if the dealer won’t do it under the normal warranty service and the reason you want the change is for track days, then do as I suggested in my first post. You can get these changes made with the added bonus of more power with the custom tune. Sure it will cost you extra over the Dealer change, but if you think it’s going to make that much difference and you really want it, then this is your only option.

Allan, there was nothing "wrong" with the throttle mapping and brake booster on the NC2. All we're talking about here is a subtle change in their character - as indicated by the quote below. I've not dríven an NC3 but we now have a couple of them in the MX-5 Club of NSW. I'll see if I can arrange an opportunity to do a back-to-back test against my NC2, and report my experiences.

The major difference for the 2013 NC3 model is a recalibrated throttle map and revised braking system.

While 50 percent of pedal travel called-up more than 80 percent of power in the outgoing NC2, the same pedal deflection produces much closer to 50 percent power in the NC3.

That makes it feel slightly less zippy than before, but keen drivers will appreciate the more linear throttle response, especially when finely balanced on the throttle when cornering.

Mazda claim "adjustment to the throttle management programme in manual models makes the MX-5 more responsive when accelerating out of corners". The above review suggests the complete opposite because the driver has to use more throttle to achieve the same result.
