We talking the custom ATP maps?? I've been considering that, but $500 is a bit steep. Might wait until I finalize all my others mods (might change my intake to something sealed to avoid heat soak) & upgraded turbos.

How many here have ever custom tuned other platforms? With how close the off the shelf maps are, it only costing $500 to get your car custom tuned to your mods is cheap. Especially for a BMW.

Does it make a big difference? I've been contemplating getting a custom tune. I'm assuming it doesn't matter what version of ots map you run ( v3 or v4 )?

The plug in tunes also have auto-tuning, which is like "Custom Tune Lite". And it would obviously be worthless to get ATP maps everytime you add/change performance mods.

SkinRock reported gains of 16 WHP/21 WTQ with a custom ATP map (compared against the OTS Sport map he had been using). COBB commented somewhere in this thread that w/ a custom map, there wouldn't be a significant impact if the firmware or OTS maps were updated. That's because the ATP facilities have access to all the tuning variables.

Bottom line: ATP Maps are worth it, but I would wait until I was done adding/changing performance mods to my car. That way the ATP Map are tailored to the mods that you have installed. If you get ATP Maps and then upgrade to RB Turbos, you've just wasted $500 on maps that aren't going to maximize the car's performance.

I know what the closed loop feedback "auto tune" features do. The point I was trying to make is that all these people complain about how much it costs to get a custom tune. Go get a custom tune on an older NA BMW and compare the costs and HP gained. Thousands of dollars for 10 to 20 flywheel HP. This flash technology has made it silly how cheap HP is and you don't even have to know how to open the hood.

ATP and ATR will allow you to make great power. I have been tuning as a second job for years on multiple different platforms and have been involved in developing a tune and testing software for this platform. If you have the knowledge go ahead and tune this car yourself. At the track I picked up a substantial mph (clutch was TOAST and my ACT is waiting to go in when I stop being lazy) with a few good logs and modifications to a few tables. If you would be more comfortable with other people who are experienced with tuning go get protuned or find someone on hear to etune / create tables for you to copy into your tables. I know I have a few locals and forum friends that have asked me to do that for their maps when ATR is released.

The n54 is an amazing platform and cobb has created great OTS maps. These maps are perfect starting points to make road tuned maps off of. Better yet - they have created an incredible tool that allows us to change the way the car is run in the dme tables instead of secondary equipment. All the hysteria of "integrated meth control" and blah blah blah is just that - hysteria. Any meth kit can have a fail safe - even with cobb. Just takes someone to not think that e90post users are the be all end all and realize that many more intelligent people have figured out solutions to integrating failsafes with flash tunes that don't have 0-5v inputs.

I run custom throttle mapping so the pedal does what I want it to (it's a mix between linear and stock throttle maps but is designed to make the car react to my foot the way I feel it should), custom timing, tweaks to boost and load, a few limit tables, and a few other tweaks that I'll get into when ATR is released and people ask for help.

Once the DA's get back under 3000 in my area (lol) I'll be back at the track putting up some crazy traps on all season conti dws and no lsd w/ stock turbos

Great post fly low. I love the way my car runs on Cobb but I know theres more power to be had with the car. I think I'll make a appointment at efi for a custom tune.

Really wish i had a protuner near jacksonville. Flylow - what kind of torque do you suspect your stock clutch was holding before letting go? I'm running s2+ Agg right now with no issues, but my meth kit is on the way. I am getting a little concerned that Cobbs beta maps might fry my stock clutch..

Save yourself the trip & go to Akuma (Woodbridge, NJ) -- That way I can come watch your ATP Maps get done

**Serious note, if you go to Akuma let me know cause I'd like to see the maps made lol

Last Question - do you have to run the car with Cobb uninstalled (or on stage 0) for a couple of days to pass emisions or can you do it immediately before the inspection?

Anyone?

Just put it on map 0 right before the inspection. Are you running catless DP's?

If you still have your cats, just bring it in to the inspection station; there's no need to do anything. Do not change maps, do not reset adaptations. If you did, drive around for a while to reset your readiness.

If you're catless, you'll need an O2 fix.


If you're going to the dealer, uninstall.

So if you've got catless DPs in, you'll need a BMS DP Fix to pass an OBD scan. If you've got the OEM DPs/Exhaust in, you'll be fine. I'd switch to Stage 0 just cause I wouldn't want an Inspection Driver abusing my car.

Thanks Guys - I don't have any other Mod other than Cobb yet. I'll likely go to the dealer and get plugs changed at the same time so it looks like I need to uninstall. The dealer is about 45 minutes away, would that be enough time to drive to reset the "readiness" what ever that may be?

1st off, if the tune is your only mod, just switch to your Stock Tune (should be saved on your AP) and you'll be fine. No need to waste ~20 mins of your life uninstalling & reinstalling the COBB.

2nd, if you don't have any other mods then you don't have anything to worry about -- You could even uninstall the COBB in the parking lot before your emissions testing.

Readiness needs certain behaviour styles I read. in sequence nobody responded as to whether uninstall restores the readiness you had before the install

Wow they are much closer, but I've Heard nothing about them. Efi seems to have some experience with the n54 from what I can see.
