mini pop bang on over-run

[TinyCappo]

Mrs Tiny and I are looking at getting a R53 Cooper S to have fun in over the summer and to replace a T6 Volvo and my little Cappuccino.

So after doing some reading it appears that the cars post july/aug 04 are the ones which do this lovely thing to the exhaust courtesy of the car spraying unburnt fuel into the hot cat.

My question is. Is this just a ECU flash to achieve this like the ECU telling the injectors to open slightly on over run or is there any physical differences between the models which cause this to occur?

Thanks
Ben

I beleive its software.

My 08 cooper s used to make brilliant pops and cracks but since a mini tech guy came to look at a fault I had he said he had also updated the ecu settings. Since then it has lost its pops and only dose it very occasionally :-(

I've spent a lot of time and effort on the maps on my MX5 to make sure it doesn't do any pops & bangs. That's just wasting fuel and risking damage to the cat

absolutely agree wastes fuel to make a nice noise for us to enjoy

Tried one today with a nice manifold, a decat and a Dave F CAI kit on it, made some stunning pops and bangs was a 2003 model so no extra fuel injection required here.

The other one I tried today was a 2005 with the pop and bang ecu software and was rather disappointed with the noise overall was just a cooper S though not a jcw or modified one.

Mine (R56) does it all the time, except for when I try to make it do so (*cough* tunnels *cough* )

My 03 R53 makes a 'whump, pup pup' on over run, rather than a proper 'pop'. Still awesome though
