I think both the red and blue lines in the diagram are pure fantasy, and not something they measured. In reality, the torque curve is not as flat as that, and it has more power and torque in stock trim. I've had our 116i on a dyno.

hi, I have had the same thoughts...To begin with I decided to go for the quite expensive Hartge tuning due to their motor warranty. But I guess it's not an issue really, since the motor actually is designed to deliver more ie. equal to 118i peerrformance.
As a alternative I have been looking at new tuning from bestchip, since the price is really fair , ie. only 1/4 the price of the Hartge tuning. And it's an external box that can easily be installed (and later removed if required...) The website is www.bestchip.no or alternative www.bestchip.dk. Has anyone experience with bestchip tuning of the 116i?? |

looking at the numbers on the spread sheet attached:
And then if the Stock cars below have these numbers 118i: 170BHP and 250Nm 0-100KM in 7.4 125i: 218BHP and 310Nm 0-100km in 6.4 The numbers for speed must be conservative, so if the 116i then had 200BHP and 290Nm I would expect it to be somewhere between the 118i and 125i.. GBR1 |

Yes, the figures don't add up. My 116i does 0-100 km/h in 8.4 seconds. I tested with logging from OBD2-data, so it should be fairly accurate. With 200 hp it should definitely be in the seven seconds range.
The top speed is pretty much only dependent on the power (drag should be the same), so it should be higher. If they can realistically add 25 percent power, the top speed should increase to 226 km/h. The car is by no means limited by the gearing. (If they can go from 136 to 200 hp as they claim, the new top speed should be 239 km/h.) |

I just got this from the UK branch:
Thanks for your enquiry. General information on our upgrades for the 1 series can be found on this page: http://www.ac-schnitzer.de/en/bmw-ca.../general-info/ We have also now released our engine tuning upgrade for the 116i which takes it to 200hp and costs £1966 inc VAT. This includes our comprehensive engine/drivetrain warranty which runs alongside the BMW warranty for the first 2 years (from new, extendable to 3 years). Standard hp is 136, and while this is a big jump in power it's only possible*because*the 116i is a de-tuned 118i. So in effect, you are getting (nearly) a tuned 118i engine. The clutch/gearbox/brakes etc are all the same so can easily cope with the increase. We also currently offering a package upgrade for the 1 series to celebrate our 25th anniversary at a big discount. Details are here:*http://ac-schnitzer.co.uk/25years.htm It looks pretty tempting to get and extra 64BHP plus I assume AC Schnitzer warranty is pretty good!? |

As the guy from AC Schnitzer said the cars are the same, gearboxes the same, same ratios etc its just the engine is restricted. If a 116i suddenly had 200BHP it can not (or doesn't seem possible) to be slower than than a 170bhp car! The 118i can only get to 204bhp and this 4bhp difference is due to a different part in the exhaust.. If I had to speculate: The 125i Auto 0-100 is 6.2 (published figure)and will have 18bhp more than the tuned 116i, so I think with the same gearing (as I believe all petrol autos have the same ratios) mid 6's should be possible.. Logiclee is the professor on this subject but the manual could be quiet different as the 125i has different ratios for the manual?? GBR1 |

Probably some mistake, true! Lets see if anyone will fit it soon so we can have some real measurements and feedback. The graph looks very good and i think that's the maximum you can get from this motor, at least without changing any hardware.

The 114i, 116i and 118i all have exactly the same gearboxes. But the final drive axle ratio in the 118i is slightly shorter than the 114i & 116i. 2.813:1 for the 114i and 116i and 3.077:1 for the 118i This means the 118i is around 9.5% shorter in each gear. Quite complicated to compare the ratios with a 125i as it's a different gearbox with very different internal ratios, for example 4th is 1:1 on the 125i against 5th is 1:1 on the 1.6's. Because the gearbox ratios are much longer on the 125i the final drive is much shorter at 3.909:1 As you say the auto's are all the same ratios. There has to be a misprint on AC's times IMO.

Regarding the 0-60mph time the tuned engine does not deliver it's power in the same way as the non-tuned engine. This can actually make the car harder to launch resulting in a slightly slower 0-60mph time, but more enjoyable (and faster) on the road where it counts. The 80-180kmh times (where you spend most of your time in reality) tell the story: 116i standard 24.1 secs 116i tuned 17.3 secs 118i standard 20.8 secs 118i tuned 16.4 secs.

All our performance data comes from real cars though. We have been doing this a while...

I would have liked to see a real measurement from a typical car, before and after. I don't doubt that gains, but the shape of the curves are not quite real. They have almost the same cartoon shape as the ones from BMW.
Also, I wonder how the tuning affects the various drive modes, like Eco Pro, Comfort and Sport. |
