Re: ECU remapping...
On the dyno chart, it shows 15hp and 13Nm increase at wheels for the E60 520i.
I PM you the price liao.

Re: ECU remapping...
Hi Snowdog,
recently got a resale e60 520 too...can i get the price for the tuning...
looking round for upgrades for the car...thanx...
also, how is the overal performance difference...
as in.. is the power felt only at high end or isit a smooth increase across the band...
thanks again...cheers

Re: ECU remapping...
If you want to see the diff in the hp, you got to go for the base dyno run before and after. But that is going to be additional costs.

Re: ECU remapping...
According to dyno graphs that we have, there is an increase in hp and torque from low to high rpm. But it is more at and after the mid range band.

Yes, you will be able to feel it.

Yes, it is reversible back to stock settings but who would want to do that if he or she is enjoying the power?
PM u liao.

Re: ECU remapping...
you can feel 10HP?
I am sure the bimmer engineers from Liepzig are not fools. Years of R&D with DME developers trying to squeeze as much power as possible from the motor. With BMW's marketing style in mind, they would have given you the extra HP.
It is true that toying around with the factory Fuel/Ignition map will gain some HP but only at engine specific load over a specific rpm range. But you sacrifice the smoothness of a free revving motor.
Smooth revving motor = quicker laptimes.
IMHO, money is better spent attending race driving schools, than to tweak extra peanuts from a stock motor.

Re: ECU remapping...
Usually, when you feel that your car rev better and a tad of better launching power, it is about 10hp.
Of coz bimmer engineers are not fools.
That is also why on the newer DMEs, they make it more precise in their work and in return makes it harder for aftermarket tuners to tweak the DMEs. But if they were to put more hp into the engine, then they will spend more time and effort to do it. Which again translates into higher cost of the car manufactured.
After programming, the engine will still be smooth-revving as before. Stock motors have got lots of potentials, that is when turbo and super-charging comes into the picture. Not forgetting NOS. Of course, all these got to be done within safe specs.

Re: ECU remapping...
The 523 is actually a de-tuned 525. The 525 still have potential (still not max out) to further enhance the power. Just that the 523 has got a wider gap to catch up.

You are on the long waiting list too...
