Just curious about this, but why are the hp figures for this tune so much lower than the other tunes while the tq numbers seem to be on par? I'm not super familiar with tuning or dyno graphs really, hence my noobish question

Yessir. I always run 93 and I believe the posted dynos for JB and Proceed show higher hp numbers, but equal tq numbers as the AccessPORT when on 93. Just wondering what would cause their to be an HP difference when the tq is equal, because isn't hp just factored from the tq at that rpm?

Hello everyone! I'm going to shotgun some answers here.
N55 support is a little ways off, so no ETA at this time. Euro support is something we will look into once we have a full product offering (All the stage maps are out, ATP is out, ATR is likely out, etc) for the N54 in the US. Currently only Stage 1 will be supported. Stage 1 is tuned for completely stock vehicles, however works well with intakes/panel filters/cat-backs. The stages beyond 1 (downpipes, FMICs, Meth, etc) have not been fully defined, so I can't let y'all know what the specifications of the allowable modifications are beyond stage 1. I have a Alpha AP heading out to work on/verify 'ix' support. Cheers, Rob |

Nice to see Cobb support for the 335 finally. Any chance you will be offering the race software like you do for mazdaspeed3 so we can tune our own maps ?

Ideally, we would like to see some customers testing their vehicles before and after AccessPORT installation on a chassis dyno so some external verification can come from someone other than COBB. Once numbers come in from other external testers, we can start comparing power numbers. Quote:

I think there needs to be maps for stock guys [intake, catback]
Maps for those who also have a bigger FMIC Maps for FMIC and down pipes. 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.

With the power of the AP i think there should be maps for Stock Stock + Intake Stock + Intake + FMIC Stock + Intake + FMIC + Catless Downpipes ... That seems to be the order of most modifications. Also mix and match - not many combinations with those 4 components Eitherway, I will place my order the moment this is available for XIs.

My 07 335i is back to stock for the winter. When you get the 07 maps set up hit me up. If you'll ship it here I'll do before and after dynos and then ship it back to you just to help out really.

I don't think I'm stealing anyone's thunder anymore (right, Rob?
![]() 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! |
