changing software - extra power & better fuel economy?
I've read a few posts on this forum about software updates, but not being mechanically minded, could anyone explain the repercussions of changing the software from the oem version to say a BBR version or any other version?
I read on the BBR site that their software upgrades can provide abt 18bhp extra and better fuel economy than the current MINI setup. I've also read somewhere on this forum that you can't get better fuel economy and more power at the same time. It's a trade off for one or the other. The last one makes sense to me, so I'm curious as to how better fuel economy and extra power is gained through a software update. Can someone explain this to a mechanical numbhead..
I'm not an expert on the BBR software or any other for that matter. However my experience with older cars tell me that timing is very important and what is optimized to pass emissions is not optimized for performance. I say this because emissions testing is more important to oem software than either performance or fuel economy. Also, if the oem software is designed to be universal, it must be designed for worst case scenario, I've heard in some countries where the mini is sold, the best octane of fuel is around 81(?).
Most aftermarket software is optimized for higher grade fuels and care very little for emissions standards. Hence they can build a map where the timing is ideal for power and will actually run more efficiently with the same amount of fuel. Hence, better gas milage and more power.
Mind you, if you are heavy footed like I and many others on this forum are, the more aggressive software map will feed your need for speed and you'll get much worse gas milage than with the oem software .
I think its burning the fuel more efficently and not chucking wasted fuel out the exhaust. I have to say with the MTH remap my MCS was using less fuel cruising along down the motorway and was more powerful and responsive when you put your foot down.
thanks guys... really appreciate it. I'm wondering whether to get a remap which is why i asked the question, considering fuel prices going up, and for a tiny car it runs as much fuel as a larger car. I've only had my MCS since July, but I'm finding it a little low of power so a couple of spikes up would be nice. Would this void the warranty? I'm not after a crapload of more power, just a tiny shot is enough.... ( I want to still keep my licence )
