remap available for the z4

Don't waste your money Jimmy ! Unless your car has a turbo you are flogging a dead horse. Very little or even no improvement over standard car, normally aspirated cars not worth remapping. :(
 
ahhh right, was thinking that. My old Megane 225 was remapped but it had a turbo so made a big difference. Nice one Kermit
 
ive had a quote for my 2003 3.0SE and been told it can be mapped to 245bhp and 320nm torque for stage 1 by a company near me for £250!

I beg to differ..... maybe the case with the Z4...

But VAG N/A engines respond very well to a remap and some fine tuning...

A good remap will cure flat spots, fueling all through the range, and re-work any red lines, and get the best of the engine at all stages and revs... it's not just about outright power...

Yes, I agree, the "gains" in power aren't as good as a force fed engine... I only got something like 50bhp increase in my S4, but with the addition of the exhaust and other bits, the remap brought everything together and ensured the engine was running at it's best...

i still struggle with remaps and wonder how a small aftermarket set up can send more power down a phone line to a back st garage and improve what the manufacturers come up with after spending millions. :? :thumbsdown:

I think a lot of it is because those £millions are spent on calculating 'averages' these are set up for the 'average driver' driving in 'average conditions' using 'average fuel' etc...
If that makes sense?!
 
I got my 2.5i remapped with a Superchip map, one of the bigger more reputable companies for mapping.

They didn't promise huge power gains but what is has done is improve responsiveness and I have zero flat spots across the rev range.

I spoke to a BMW tech about mapping and he said they are worth doing but a) be careful with what map you use, and b) don't be too greedy with the power increase.

Paid about £190 for mine they were offering a discount at time, 192bhp to 205bhp :-)

Haven't had my BM mapped but I did have my Normally Aspirated VX220 done and although it only gave a small power increase (5-10bhp) the difference in engine response and character was very significant and was well worth the money, I subsequently remapped an S2000 and effectively wasted my money.....I suppose there''s nowhere really to go when your already getting 240bhp out of a 2.0.

I think with NA cars some benefit more then others (based on my "very limited" experience those with lower then expected outputs) and I'm not sure about Z4's but at least on mine only 230BHP out of 3.0 6 cylinder is positively lazy.I would imagine there is room for improvement so am very interested anyone's experiences.
 
There's been lots of discussion on this on the forum over the last couple of years. Not seen any proof yet to confirm anything more than a modest gain from doing it.

There have been claims of 30bhp from a remap. But. Really? I think in reality you'll smooth out a few flat spots and may get a better throttle response.

30bhp for £250 sound too good to be true. Which probably means it is
 
If you look in my project thread the dyno runs are there from when I had mine done
Not massive gains

Rev limit raised, flat spots removed, quicker throttle response

Would I get it done again? Yes

They spend millions getting the car to run well in any condition, ie the hot summers of califonia or the cold winters of russia. High altitudes or at sea level. If you set a car up to run well in one and then sell it in the other place its not going to run very well so they set the car up to run well everywhere so that is where tuners find they can tweak things
