EFI Logics Custom Calibrated Stage 2 335ix

Yesterday we custom calibrated a customer’s 2009 335ix automatic using the Cobb Accessport. The car gained a massive +62whp and +100 wtq at 14psi peak boost over the stock baseline map on 93-octane pump gas!

As previously stated, the car is a 2009 335ix automatic with less than 30,000 miles. The only power modifications consisted of an intake and downpipes. Per the customer’s request, we tuned the car for 93-octane pump gas, sharpened the throttle and calibrated the car taking into consideration the specific modifications that were made. AFRs, ignition timing and all critical engine parameters were adjusted to optimize power potential while ensuring safety. We are very impressed considering this 335ix only has minor bolt-on modifications, it's still utilizing the factory intercooler and it has substantial drivetrain loss being that it’s an all wheel drive, automatic vehicle. That being said, with all four tires clawing at the pavement you can surly expect this 335ix to throw you into your seat upon request with all of that power and torque on tap! An enlarged intercooler core would help keep the charge air intake temperatures down and enable the N54 to produce even more horsepower with more aggressive calibration.

Here are some photos of the meticulously clean and tastefully modified 2009 335ix on the dyno along with a video of one of the pulls.

Hey guys I got a few buddies with Subies that you guys tuned. They've been telling me how you guys have been tuning 335s. I got an 07 RWD e90 with a jb3 on map 5 and bms dci. I'm interested in what you guys can do for me I'll be giving you guys a call 

they can do nothing for you with the JB3... you'll have to get rid of that and get a COBB AP

Josh, how did this test car dyno on the OTS Stage 2 aggressive map? The owner has the correct mods for the map. How can we tell if the owner made any additional power over the OTS stage 2 maps with a custom tune?

Do you have a dyno pull from what the vehicle produced with the OTS Stage 2 maps to show the delta between OTS and your custom tune? Without that is doesn't really show if there is much benefit going the custom tune route.

EDIT: ^Ben beat me to it

+1. but I guess a 100wtq increase is still impressive even if we consider stage2 agg to be the base map, but it would be definitely nice to see a stage2 OTS dyno

x 3


this will show the value of the EFI tune (gains over the off-the-shelf maps)

I am sorry, but our software only allows us to calibrate cars with the Cobb AP.

Sorry guys, but unfortunately we never did a pull with the car running the Cobb OTS Stage 2 map. The owner was running the stock map beforehand (was at the dealer the day earlier) and so that is what we used as the baseline. We will be tuning a stage 2+ 1M soon, I believe this Saturday, so I will try to make sure that we capture the gains over the OTS map for you.

For what it's worth, my 135i picked up 28whp and 40wtq over the Cobb Stage 1 Aggressive V301 map. Power gains over the OTS map will vary from car to car and will depend upon a number of variables. For example, if you tell us you consistently use high quality 93 octane fuel from Shell every time you fill up then we can calibrate your car taking that into consideration. If you tell us you travel a lot and may come across inconsistent fuel quality every now and then we will design the maps to be more dynamic/conservative so your car isn't at risk if you encounter bad fuel.

We are going to be exploring a 100 octane custom race gas tune for my 135i soon as well and possibly dive into what can be done with E85. Expect to hear more from us soon!

-Josh

Here are the results from custom calibrating the stage 2+ 1M I had mentioned to you guys before.

I'll have to come see you guys since I have a 6AT XI also. I'm actually curious also about the OTS Map vs the EFI tune... running stage 2+ map now.

Please see the above post. If you want to schedule a time to come in just give us a call.
