Cobb AP - How sweet it is...

I am VERY conservative when it comes to mods...generally I believe that the collective engineering might at BMW knows best. However, I also know that they need to plan for the extremes - pulling a trailer upa mountain in the thin air of Colorado on a very hot day. So they build in margin for these outlier situations.
After lurking and reading about ECU tunes for years - I finally felt that Cobb would be a good choice for me as it did not require messing around with the ECU box itself. Further, they were now were several releases deep intothe N54 engine.

Installation was just as described. A bit worrisome to see all the lights on the dash and Nav system during the read and write phases - but the on-line videos had managed my expectations regarding this. The first time you install the Cobb it needs to first read your stock map - so plan on 20 minutes or so.

I was at first not clear that 91 octane applies to map drive and sport and if you have access to 93 octane - aggressive is an option. Being conservative - I installed Sport with Stock throttle even though I exclusively run 93 octane. I figured that I could always change to Aggressive later and it would be like installing another mod.

My first drive of 2-3 miles I did not notice a whole lot. However, after some additional driving it really makes a great motor fantastic.

One of my biggest fears is that the absolutely perfect (smooth + linear) power delivery of the N54 would be less perfect. HAPPY to report it is the same perfect motor just more of it.

My advice - before you install a tune (we will call that Stage 1) - be sure to do a stage 0 upgrade. Take you car in and make sure plugs and all recalls etc are current, and most importantly make sure you have the tires to support your performance. I installed Michelin Super Sports (staggered) this spring.
The 5 series is so quiet and so smooth that you will find yourself entering corners faster then you realize. I now realize why BMW keeps the tune mellow - country club wives could get in trouble.
Note that with the Cobb daily driving can feel as mellow as ever - but your old 70 on the freeway wants to creep to 90 with the tune if you are not careful. Further when you use 3/4 throttle - the cars you just left behind at the light are simple long gone. I have not used WOT - probably not much more there. The car feels lighter as the power to weight has improved.
Im looking forward to installing the agressive 93 octane tune - hoping it is just as user friendly as the sport.
I drove the current M3 with a stick and I prefer the tuned 535. It simply is a better all around car for most people that do not go to the track.

Having said that, I am saving my pennies for the upcoming in line 6 M3/4.

Ptziems,

I can sell you my Cobb AP for below the regular price if you are interested. I just got the AP new about 2 months ago.

The reason for sale is that I am thinking about selling my car.

I have to agree with Mermar though, its a sweet tune.

Have fun and be careful cause it is addicting. Ive been running the Stg 1 Agg LT map for a couple of months with a 75/25 ACN 91/E85 fuel mix. It definitely makes a big difference, especially on freeway onramps. On a couple I would top out at 80 before merging onto the freeway, now I've got to lay off well before the merging area. Have fun with it.

difference between sport and aggressive mode

Anybody with expereince care to share their perceptions on the difference between sport and aggressive. Does it retain the great driveability and smoothness of the sport?

The highest octane I have near me is 91. E85 is nowhere to be found. Should I bother getting the Cobb or would it be a waste of money (with 91 octane)?

I ran the stg1 sport map for a couple of months and liked the improvements over stock. IMO it is worth it.

Well if you head south you can find e85 and run a 4.5gal e85 and 14gal of 91 to get you a tank of 94 octane roughly for the stg1 aggr map.

Just curious if Cobb supports the blending of e85 with regular gas? Also, any valur to adding a bit of e85 to a tank of 93 octane?

Thanks

With ATR you can tune for e85. Running it without tuning for it won't do much for you. However, ATR is free and you can adjust your timing, boost and fuel scalar levels in ATR to take advantage of it.

They do have a Race Map that you can load but you need to be FBO to run it. For $200, there are guys who are very familiar with the N54 engine who can make a custom tune for you.

Congrats on the new found power, mermar! Should be great fun with it, but of course one thing leads to the next, you'll want to do something again to up that power!

I'm from Canada as well. it's best investment ever except i got 2 ticket within 3 weeks time as i don't use to the power
also, it save more gas. my average before flash is 11.9L-12.3L. flashed become 11.4L to 11.6L. This is all base on City driving. I'm confidence to say i should able to reach high 10's if it's hwy driving.

You bring up a good point. What are the affects that everyone has seen on gas mileage. 93 octane here is now over 4.50 a gallon.

Hey xclone how's it goin. Yeah right now I'm using e85 to boost that quality ACN91 up to 93/94 octane. I'm thinking of getting a etune at protuningfreaks once I get my DCI installed. Wish I had someone locally who was a Cobb protuner for BMW's.

In CA? I'm sure you can throw a rock and hit someone. DZ over at PTF really knows what he is doing though so once you get your DCI's, definitely get him to tune it for you.

I live in norcal and there are no real cobb tuning shops for bmw, mostly subees and evos. There are a bunch in socal but id have to take a 5 hr drive south for that. Ill look up DZ once i get my new toys installed. Thanks for the recommendation.
