You won't have issues running 93 octane on a 91 octane map due to higher octane gas..

If you overheat you will get limp no matter what map you run...if you heavily track your car you should invest in some cooling mods (e.g. auxiliary oil cooler, maybe even an aftermarket radiator, air ducts) so you have proper cooling and you avoid overheating...

What should i expect for oil temp... just got Cobb with 07 335 (no oil cooler) , just drive it street and want to have power at times... i'm not racing it or tracking it.

I've been running 220-230, when should i get concerned?? 240, 250??

There is a recent thread discussing this here http://www.e90post.com/forums/showthread.php?t=541355. Seems like good temps for Arizona and you should be fine because you are not tracking or racing.

On a side note, what maps are you running? Have you tried logging your car with the 91 ACN (Arizona, Cali, Nevada) maps vs the 91? Just a consideration to make since you are in Arizona.

I do an uninstall. Turn the car completely off. Then on again and use the clear all code function again using the AP. Might be overkill but it takes 2seconds and I've had 3 visits to the dealer (1 to work on the turbos under warranty) and no issues.

Understood. But in the situation where you want the dealer to do unrelated warranty work (injectors, fuel pump), you may want the codes. Best thing to do, then is to drive a bit until the codes reappear.

Running 91, haven't seen the 91 ACN map, I'll look for it. Man - this car is a monster now with the Cobb and Dinan CAI. Torque feels like my old high school car - 69 Camaro SS

Haha niiice!

The maps are found on the Cobb site under the Calibrations tab. http://cobbtuning.com/products/?id=5833. Use the Cobb AP to identify your correct ECU ID.

Hey guys, I'm currently using a PROcede, but just bought a Cobb AP (should arrive early next week). I have a BMS DCI and catless DPs. I've seen other threads where people are running lower than normal boost because of the additional air flow. Just wondering what is the average boost people with those mods are seeing? 13-14? 10-12? I'll take the car up to the local track for some runs and will report back.

[Imperator]

What additional airflow? The AP is a tune, not a breathing mod. If anything, we're seeing higher than normal boost levels in hot weather, as the tune utilizes the DME's logic of torque targets. Conversely, we're seeing lower ignition advance than other tunes as the AP Stage 1 is a bit conservative on the timing table and safe enough to use on factory hardware.

[Imperator]

That's true, it's just the nature of a torque-targeting tune that is optimized for stock components.

[rader1]

Making the same or more power at lower boost is always a plus

[bulldog_yyc]

so is this weird or what - the CEL in my car turned off (due to kittyless DP's)? Reflashed to 94 octane map (auto cleared CEL), drove for a while, CEL came on and now, it has magically turned off.... maybe its the formulation in the 94 octane or perhaps the car has figured out that I dont care about the error code lol

Would be nice to get a stage 2 file to turn off kittyless codes properly though, hint hint, nudge nudge Cobb....

[dyezak]

Just spoke with Kevin yesterday and there is going to be some new maps coming other than stage 2 as well. He said they are going to be doing Stage 1 with cat codes turned off as well, so you can run Stage 1 with downpipes...

[Magic-Man]

I'm still on the fence on the AP due to all the people having limp mode & CEL issues w/codes that won't go away.

I have an '07 335xi auto & only other mod is BMS DCI. I run 93 octane. I don't plan to add anymore go fast mods.

limp modes are not Cobb related, they're cooling related...if you push your car past its cooling capacity it'll overheat, even on the stock tuning...this is why there's the 335IS and performance package to provide adequate cooling or just get an aftermarket oilcooler/radiator and you'll be safe from limp...

CELs are not issues either...people get them due to running catless..

Nice, that is clutch. Did he have any idea when they would be ready for distribution?

I don't ask those questions. It's ready when it's ready.

So the only CELs people have gotten after installing the AP are ones running catless DPs & the CELs were due to the DPs only?

According to what I've read, every AP user with a limp mode didn't have a cooling issue.

There is the 335is etc b/c BMW didn't do it right & put an oil cooler on all the 335s.

Lots of people are quick to blame any tune without realizing there are other factors in their problems.

For some people this is there first tune and only tune they have tried, when you increase your boost, you will find any weak links in your car.

Majority of any problems start with the following:

Spark plugs
Coilpacks
Injectors
LPFP
HPFP

If anyone of those are on there way out, a tune will find that flaw.

As far as any other limps, a misfire limp can be related to the above listed, and a cooling limp can be related to pushing the car to hard given the conditions.

Hope this helps clear any concerns up.

The only CELs i know of were for dps and Hpfps going bad and all the hpfp issues were covered under warranty.

Any word on a meth only map or is that synonymous with stage 2? I've been running the ACN91 maps for about a month now and could really benefit from Meth and higher octane equivalency.

Also could a PWM type system work with a Flash? Or is that only limited to piggybacks?. Might have to consider Procede/PWM solution if it's not possible...
