73 whp gain bro look at the base dyno 240 , it just must of been a mustang dyno.

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?

I thought the difference was MSD 80 vs MSD 81 but I guess I'm wrong since they support all 2008's.

Someone mentioned that the 07MY's had an MSD80 which is not yet supported, and different from the following years.

That's what I thought too, there's a whole bunch of 2008 335's with MSD80 out there. They started putting MSD81 in April of 2008. All 135's are MSD81. No idea about 535's.

Maybe Cobb isn't aware of this?

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.

Thanks for the clarification. I can't wait to get this thing installed!

Now for some XI love

HFC with or without downpipe ?

Each of those are significant power adders for this car and it would be a waste that the tune doesn't account for them individually since not everyone that is willing to do a fmic is also willing to mess with the downpipes.

That what the stage 1 map is for. You take that as your platform to start with and build your fine tunning in a dyno shop. Of course work with a Dyno shop that knows how to use Cobb Accesspoint, better if they are resellers.

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

if it is only an issue to bring 2 CAN wires to the odb port, then it is easy to retrofit

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

It has a different DME (MSD85).

That is an absolute need for sure.

In my limited participation with pre-production testing, I can state the Stage1 maps are everything as advertised. It feels as if I've picked up 50-60HP right away with the tune and I hope to be able to prove that tomorrow with a dyno demonstration at the Plano location. Power delivery is very smooth and linear, there are no hiccups or issues with the tweaked tune. My car is otherwise bone-stock right down to the paper filter and the output feels much like the piggyback tunes we're all used to, except that the Cobb Stage1 tune feels smoother and the added rush of torque comes on very early.

Fast map switching and data logging are the immediate benefits that I enjoy most with the AccessPORT, but it also has the capability to read and clear OBD codes and provide performance measurements. The handheld can read a number of commonly-referenced parameters including RPM, load %, TPS, vehicle speed, battery voltage, MAP, oil temp, water temp, boost pressure (actual and requested), ignition timing advance, wastegate duty cycle, ambient and manifold air temperatures. I'd like to see the inclusion of knock retard, and I'm sure that will be added in later firmware revisions.

All of those values can be logged instantly with one click on the AccessPORT handheld. These parameters can be recorded for a set period of time (I'm not entirely sure of the intervals) and dumped into a .CSV file right on the handheld. All of these logs can be transferred to your PC in a matter of seconds over a USB connection using the AccessPORT manager software.

The initial extraction and write can take up to 20 minutes. During this time, you'll see several trouble faults indicated on the DIC and iDrive displays-- some of these faults might include TCU (for autos), HPFP, ABS and DCT trouble codes. Ignore these warnings--they'll disappear after the load is complete and the trouble codes will be reset once you turn the ignition off for the first time. During the initial load and subsequent map switching, you'll likely hear the in-tank fuel pump running. For those with aging cars or aging batteries, I strongly suggest connecting a battery charger to the vehicle before starting the initial load. This will prevent battery drain while the fuel pump and accessories are energized and will provide a more reliable connection to the AccessPORT by stabilizing battery voltage. After the initial load, map switching takes 5 minutes or less to complete.

I'm looking forward to additional tuning development-- we should soon see additional "staged" maps including those that support specific modifications and user-tweaks. I should be at the COBB Plano facility tomorrow to demonstrate the AccessPORT to anyone interested.

Thanks COBB!

What other tunes have you had experience with on your car and for how long?

My only concern with that is how qualified are these Cobb authorized local shops in fine tuning Bmw's? Obviously this platform is a lot more complex than your average subaru since its taken them years to finally come out with a tune.

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.

According to the response I got:

Its a firmware support issue and not having anything to do with the OBD connection or the Accesspoint hardware itself.

Edit: So if the OBD connection ports are different as you say then the AccessPoint OBD connector should be retrofitted.

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



Compared to GIAC S1:

[jpsimon]

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.

JB3 and Procede V3, both in service (installation/removal) and driving on friends' cars. This thread shouldn't be about comparing tunes but I included the remark to state that my seat-of-the-pants experience leads me to believe the COBB Stage1 tune is not leaving power on the table compared to other tunes--at least not for an otherwise bone-stock car.

I see a new firmware was released this morning so I've got some more testing to do!
