Why such a big difference between the 135i and 335i now? 303/363 for the 335i but 350/349 for the 135i?

The calibration has been updated and the 135i will be back on the dyno this afternoon. We should have a dyno graph with power gains that are more in line with what we are seeing on the 335i posted later today.

Thanks!

Very nice. I will be ordering one of these.

Imperator · 01-07-2011, 01:11 AM

I just got back from Cobb's "First Thursday" event here in Plano and was lucky enough to get my car on the dyno to show the results from the tune.

As previously mentioned, I've been running the Stage1 93-octane map on my car for the past three days and am very happy with the results on the street but anxious to see how they looked on the dyno. My car is a 2010 E92 steptronic with 7300 miles on it and bone-stock right down to the paper air filter. With the tune alone, we picked up 53 HP and 98 ft-#! My last numbers were 311/384, plotting to ~6500 RPM. Peak power arrived right at 5000 RPM and torque peaked early at around 2800 RPM, holding at or above 360 ft-# through 4000 RPM. These are great results through an automatic! The wideband A/F reading looked really nice too, holding steady at around 11.5:1 from 3200 - 6500 RPM.

Cobb uses a Mustang 4-wheel dyno which differs greatly from the inertia-based Dynojets we're used to seeing plots from. The Mustang is a better dyno for tuning applications and calculates its numbers differently from a Dynojet. I can't say how my results translate to a 2-wheel 248C but I think my next set of mods (downpipes and intercooler) will follow a few pulls on a local Dynojet just so you can get familiar with the numbers.

Did Lance or Rob load your dyno into our Dyno Database Online? If so, we should be able to host the graphs for other to review.

If not, I can ask them to do so for others to review some time tomorrow.

I believe it is. Look for "BECKER"

Cobb Team - Can someone please answer this question being addressed. It has been asked twice so far and no replies.

Thanks

Unlikely, perhaps, but I work in IT and have to flash certain devices from time to time, routers, phones, BIOS' etc -- they work most of the time, but occasionally it'll go wrong and the device becomes pretty much null & void.

The last thing I'd want is a bricked BMW DME.

A quick Google search yields some threads from STI owners who managed to brick their ECU. Is this something we need to worry about?

I know it is a while off yet, and it has been asked before, but it didnt get an answer from the COBB team, but any chance that you will be doing something for the 1 series M coupe in the future? Since it is a N54.

yep this is very important

What I don't like about this Cobb thing is that they seem to emphasize the hardware side of things (AccessPORT) instead of emphasizing the power gains, the maps, driveability, how they manage to make big power with low boost, etc. I would never buy a tune for the auxiliary stuff it comes with.

they emphasize what distinguish them from other Tuners - Flashes. We will have to wait and see how their calibrations are working and what kind of performances they are able to get out of the cars.

**335i** · 01-07-2011, 05:34 AM

yes would be nice to see some runs in youtube

If any of your offices are near DC I wouldn't mind testing it on mine

LOL, and here I feel like it's going to be forever between the N55 Support for you guys and the Support for the N55 X5/535 crowd... Our ECU's are programmed differently than the N55 135/335's. Probably something to do with the 8-speed tranny's we use, among other things

Black Gold · 01-07-2011, 08:17 AM

My accessport will be here this evening. if nothing has been written up yet I will post my experiences. Previuosly I had a v5 and now it is completely uninstalled.

My car is bone stock and a 6mt running on 93.

AWD Addict · 01-07-2011, 08:36 AM

Did the "Thursday Event" happen? Any cool vids or pics? What'd you have on the dyno?

Jealous. Copious pics and info expected. So park the damn thing after too long and get back to your keyboard.

But yet there is still such a big difference. Previously I think the 135 made even less than the 335 on the dyno now it's flip flopped.

Is this through your own testing or has anyone actually brought one into the dealership?

Edit - I'm an idiot. Apologies Mugen.

Cobb hasn't posted a new chart with the updated 135. You're still looking at the one that is "suffering" from their calibration issues.

That's they was it was on subys too.

Really? Did you read the thread?

BTW results look nice...personally I love the claimed af ratio.
