is this tune restoring the "turbo lag" to the original pre 29.1 throttle response?
Discussed here on the forum, GIAC restores the wastegate PID to the 25.1 program, it is the most responsive does the AccessPort do the same? |

It would take me 1550 miles from NYC, so probably an additional 300 miles for you... If only I could take the time off from work for a road trip like that... Then they would have an N55 X5 to play with for a week or two...

its not about the MSD80 or 81 . is the OBD port which in very early model is not the same as the newer models. Check as well Rixster P3 gauge thread. same issue.

+1 From MY 2008 on there are CAN signals in the OBD port.

Cobb Tuning guys -
I hope you also will be taking a look at the 1 Series M Coupe. It will only be available with a 6-spd manny tranny (no DCT) and will have the so-called N54 B30 Overboost motor -- as is currently installed in the Z4 sDrive 35is and the 335is. The 1M is likely to have a slightly different version of the MSD81 DME since --unlike the Z4 35is and 335is -- it will come with a "M Drive" button that actuates more aggressive throttle response. EDIT: As pointed out below by Prince ///M, the Z4sDrive35is has a MSD85 DME -- not a MSD81 DME -- as I stated above. Presumably, the 1 Series M Coupe will also use this DME.

I think it will be worth the money to have a custom tune specifically for your car and your driving habits. |

![]() but if the protocol (the language) that the 07 ECU talks has changed 08 on-words then it needs another firmware |

Cobb - does your software make it very simple for Protuners to make adjustments to fine tune things without risking the safety of the motor by making changes way out of line? How much actual real world testing was conducted with your tune (hot and cold weather)? Curious if you guys ran into any tuner code or cel issues and will this be a flash that is still very much in its infant stage where more real world testing is needed by early adopters or if its something pretty much tested up its a55 and is pretty much bullet proof at this point. Alan

Edit: So if the OBD connection ports are different as you say then the AccessPoint OBD connector should be retrofitted. Last edited by BQTuning; 01-06-2011 at 11:38 AM. |

I am wondering why the HP and TQ graphs are so choppy:

That is due to the smoothing applied, the AP one appears to have no smoothing while the GIAC has a lot of smoothing

I see. Is the smoothing applied by the dyno computer? Because my GIAC software has always felt extremely smooth and consistent.
