E85 2L remap???

Sorry but the brutally honest reality here is you would be better doing what Skelters suggests. Remapping a 2l NA for the power gain is basically pointless. As B21 said even a +10hp is 7% which is quite optimistic with just a remap. If it was me id buy a few stickers for the car.. you will get more power out of them, Z4 Forum ones are 10bhp a piece 
I wouldnt even bother remapping my 3l coupe... its only 18bhp. If I lost some weight Id feel more of a difference

I can understand what you are saying to a point but remapping when done by the right person is not all about bhp gains . If you get it done properly one major benefit is you will get more power available lower in the rev range where it is needed . Useable power at the right time rather than big power gains

Have you seen any printed power curves that show these gains? How much of an increase are we talking :?

Plus even if you're going to go down the route of drivability/response, when you have such a limited power band to work with the results are ultimately minimal.

Hi Rob,
I don`t know what it would be on the 2 ltr and what I am saying is it`s not just about bhp gains when remapping it`s more ( for me ) about getting the power in the right useable area . I have read some posts on this forum from other forum members saying the same thing . Tuners come out with all sorts of quotes about what they can get but if you find yourself a company/tuner that knows what they are doing then it can make a considerable difference to how your car performs . I think that for the amount that jock156 is being quoted it may not be a great remap but find the right person and even if you get no bhp gains the power will be where you want it .
I recently answered a query about a remap here and it has a link to my printout etc https://z4-forum.com/forum/viewtopic.php?t=133051
In a nutshell - remap done by the right person should get you a better driving experience even if you don`t get an increase in BHP .

I think you must be talking about an increase in peak bhp not being achievable, to obtain an increase you can feel (even in the midrange) the car must be making more power, if it’s making no more bhp in the midrange then it won’t perform any better?

Yes a remap can make more useable power in the mid range even if the overall peak bhp doesn`t increase . That is the point I thought I was making :?
I assumed ( the mother of all f**# ups ) that when discussing claims of an increase in power of 10% by a tuner we were all talking about peak increase as that is what they normally claim ?
Anyway a good discussion to keep my brain cells from deteriorating any further

I would say if you want a remap find a company that has a good reputation and uses a rolling road or the other way is they plug a laptop into the cars obd and sit next to you whilst you drive the car on a quiet A road for example going through the gears etc . These normally cost in the region of £300 . The other way is to see if someone else has had it done on the same engine as yours . Whatever you decide its been a fun discussion
