ECU tune for M135i COMPLETED
Had the Hartge tune completed yesterday. Initial feedback: Huge difference in power output in sport and sport plus mode through the lower to mid range. However in comfort zone I am pleased to report I can feel a marginal change in acceleration. Exactly what I expected.
As this tune was only completed yesterday, I need some time over the next few weeks to really analyse the acceleration and power. Will have the dyno completed over the next few weeks. My next dilemma is where do I have the next service done? At the dealer or the performance centre that did the tune? Feedback please? |

Congrats, will be a complete beast now!
I'd go to official dealer for maintenance, else you'll lose guarantee on anything that happens, even when it is not related to the tune at all. |

At the dyno, you only be able to measure power in comfort mode, unless it is an AWD dyno. The driving aids will go crazy if you accelerate at full power with the front wheels stationary, so it is only possible with DSC Off.

Congrats on the tune though. Was this done through Ramspeed?

You refer to Bob Jane for your tyres, but figure this terror: you blow something in your transmission (driveshafts, end bridge, gearbox, clutch and all other small stuff in between), BMW will immediately waive any responsibility because of "unauthorised" torque increase putting excessive strain beyond engineering specifications. But this they will do irrespective where you have your maintenance done. But now we're mixing two things: the driveline is no longer covered by BMW anyway, but I assume that Hartge inherited the guarantee (at least for the engine, not the transmission) and that a part you paid for this tuning is this guarantee. BMW will always waive any responsibility on engine and entire driveline. Also when they do the maintenance. I refer to other aspects, when they don't maintain, you'll lose guarantee on body erosion uptil light bulbs or upholstery in the interior also, so the remaining entire lot! I guess that these terms are concrete and solid (none negotiable)? |

Day to day driving in sport mode, driveability off the mark is an instant through the head back into the seat feel. The acceleration is ballistic! However in comfort mode driveability is fantastic.

Did you have to take it their workshop in Sydney? Are there any specifications for octane ratings of fuel?

Had to take the car to Seven Hills, location of the workshop. I normally run 98 octane and would not consider anything less than 98. As for the cost I suggest you ring them for a quote. If you go on to the HARTGE website you will see the cost for the ECU in euros.
