Hey Guys, figured some of you might be interested as we recently did a test between a 1M Coupe and an E90 M3 (DCT), both stock.
We did about 15 pulls which were all from a roll, starting at between 20-70km/h up till about 220km/h. The results were as follows: Roll - 160kmh: 1M ahead and pulling away slightly (2 car lead) 160 - 170kmh: 1m stops pulling away and the M3 starts to close the gap. 210 - 220kmh: M3 passes the 1M and pulls away. I would estimate that if both cars were to pull all the way to the electronic limiter at 250kmh, the M3 would probably be about 2-3 cars ahead. What was also interesting was that after 15 continous pulls with no more than 1 minute in between, the 1M did not suffer any visible deterioration of performance and the way the drags played out was very consistent. This was all done with an ambient temperature of about 29 Degrees Celcius. On the contrary, a 335i (Auto) with JB4 and full Exhaust mods was slightly faster but would hit "limp mode" after only 6 pulls. This brings to my mind the question of whether it is worth tuning the 1M at all. I was considering putting on a tune along with the Akrapovic Evolution system and the BMW specialist garage here suggested the JB4 which they are an agent of, along with ESS. I was wondering if anyone would be able to give input on these two tunes, specifically if it would increase the incidences of hitting "limp mode" - something that I am not prepared to deal with. I tend to do more road driving rather than track work, and some of these road drives would see us cruising at between 180kmh and 250kmh for up to 300km at a stretch, with lots of hard pulls in between.

What's the speed limit in Singapore? Do you get canned in addition to speeding ticket if caught? |

Not in Singapore unfortunately. Max you can do here is 90 kmh. Across the border in Malaysia, which is about 25minutes from Central Singapore, you can do a direct drive on a freeway that takes you to Thailand in 1000km.

We have the world's first M dedicated dealer here in Singapore and they are strict with warranty work, as we enjoy a 5 year (100k km) warranty which also includes free maintenance and the replacement of all wear and tear items, with the exception of tyres. |

EIN M,
With the ESS tune on, are there any of the normal factory functions that are affected, or does everything remain the same? Also, would you consider the throttle modulation and power delivery as linear as the factory set up? In terms of all out performance, how would you rate the ESS tune versus the stock car in a straight line? Just out of curiosity, did you at any point consider a flash tune like JB4? |

Throttle modulation is as linear as stock in "normal" mode and as exaggerated as stock in "sport mode". Also, it's hard to believe but the power delivery is actually smoother after the tune. The best way I can describe it is that the gas pedal has less of an "on-off" switch effect to it and you can actually meter the power more effectively in relation to throttle position. I wasn't expecting that benefit and was very pleasently surprised by it. Acceleration wise it feels stronger all the way thru. I won't tell you that it's a night and day difference because it isn't. It just feels like the HP and torque curves have swollen a good amount. For sure I can't get full traction in the first three gears. Even on full throttle in third gear I get wheel spin and "tail wagging" every time I'm not sure how the car will accelerate in the stratospheric speeds you guys are playing in, but I took it to 225 kph once and it was still pulling as hard as it used to pull at 160 kph (or at least it felt that way!!!) I went with ESS because of their worldwide reputation, extensive BMW knowledge and the convenience of the DirectFlash in swapping the stock profile back and forth quickly (cars need to go back to service now and then ) I hear that they are currently working on their "Stage 2" tune so potential future power gains are there. |

Unfortunately no increase in "turbo whine" althought I would have love it....non-cated DP perhaps would do the trick there... Glad I could be of assistance! I'm sure you'll be very happy with the ESS tune althought I have to warn you that it was so fun and satisfying to increase the engine power that now I find myself plotting my next mod |

Very good to know! I narrowed it down to ESS / EVOLVE and JB4, though I have never been fully comfortable with the idea of a piggyback. Looks like ESS will be the right choice given we have a dealer here. |

With the ESS handheld flash unit, how long does it take to flash the car, to/from stock?
I think I saw a video of GIAC handheld tune that was able to switch tunes on-the-fly (as in while you are driving)... |

It took about forty minutes for the DirectFlash unit to read the original file from the car. Downloading the modified (stage 1) file to the car took about half that time.
