I just purchased a cobb ap and I have an 07 335 completely stock
except for dci's.
What will be the best map to run?
I have no problem running 93 or 94 octane.
What will the powers gains be?

Thanks in advance for schooling me.

stage 1 aggressive. on cobb site there are dynoes.

With no DP's, or IC you need to stick to stage 1 aggressive based on your E93 availability. you should gain around 40-50whp with just the tune and your DCI.

Is it possible to do a custom stage 1 e85 tune? I guess I should clarify...by "possible" I mean "a good idea".

I'd rather not do catless downpipes on my car. I do plan on upgrading the FMIC though.

sure get ATR , change scalar and up timings.

Hi all, just jumped ship from Giac to Cobb.. because i wanted to move on to the E30 maps or a protune.

just loaded in the stage 2 aggr. v402 map and tried to do my first logg.

would anyone be able to take alook at these and see if everything looks good before i move over to the E30 maps.. Thanks in advance for all replies.

Bought a COBB yesterday and I was wondering how do I find out which ECU I have so I can find the appropriate maps?

If you can do ATR go for it, that is out of my comfort zone.

Or you can do a Pro-Tune or E-Tune. there are great gains when running ethanol, I am sure a lot of us can confirm that.

Good luck!

Thanks buddy.... sorry for the stupid question I have never done this before and I just don't want to screw up the ECU or something and load a wrong map and have my car not work.

In the video step #6 is 'Power Cycle the car and the AP Install Process is Complete'...... does that just mean I press the start once without my foot on the clutch and then once again right after with my foot on the clutch to turn the car on?

Thanks for the help.

I almost choked for a second.

I am only familiar with US Standard, I can't read Metric.. I am sure someone could help.

Also, most of us like the default logs data fields. You may want to reset you data logs and add two more to your liking. I can't tell when you go WOT.

no worries, most of us had the same questions when we started. feel free to ask anything, but just do some searching first, Google usually works best because it will typically bring you back to e90post.com

oh didn't read the whole thing,

i believe it says no clutch or brake pedal. When Key is in, and the OBDII and COBB is plugged in, just hit the start button ONCE. when complete you hit OK on the COBB, and then take the key out, then start the car as normal.

They've made that really easy...just get the E30 race map to start.

Yeah, unfortunately we're at the mercy of the supplier when it comes to percentages. Consistency is important as well as logging after filling up to make sure things still look good. It takes about a mile before I start seeing changes with the % after filling up.

I completely understood where you were coming from, but some people take everything as gospel. I just wanted to clarify e85 being 85% ethanol was more a rule of thumb and can very widely depending on the vendor. It's always advisable to fill at the same station if possible, but you should still log after fueling, unless you have a sensor. Even with a sensor I feel better pulling a few logs as things change around here quickly. Today when I dropped my daughter off it wasn't even 60 yet. Mid afternoon and it's only in the mid 60's now. Time to hit the track...

It would be nice if one of the vendors put together a fuel sensor kit with a gauge. I have the FFTEC/Vishnu Flex kit that connects to the PROcede, but that doesn't mean other tunes can't take advantage of the flex sensor. The fuel lines are using spring locks and it's easy to install the inline sensor. Just need to run the wires and setup a digital gage to read the voltage output. I know most people will want a new sensor, but you can find them on ebay for @ $125. Just want to make sure you get the spring lock connections.

Unfortunately Shell hasn't stepped up to the plate here in Portland OR with flex fuels. As green as this city tries to portray, we only have two private old time service stations that offer e85. More than likely they are getting e85 from the same vendor. So it's a 20 mile round trip to fill up... But the trip is worth it....

BTW, I'll be at Shift S3ctor the 10th and 11th. Any chance you'll be going? The more BMW's we have show up the better.

with a pro-tune, what matters is consistency, the tuner obviously tunes the car based upon the data and results, so E50, E48 can vary. So as long as I can do the best to make it consistent, and check data logs from time to time I should be fine. Once again i don't have the flex sensor to make adjustments.

But my comment was just being technical, E50 is not 50% E85 pump.

Just curious, which brand of E85 do you use? That is interesting that you are getting that much of inconsistency. thanks for sharing.

I use Propel Fuel @ Shell and they have some in the Cali Sac valley, Bay Area, So Cal and Washington. Its a high profile brand and I spoke with them before. They appear to be very consistent with the blends and they do not reduce the ethanol content during the winter months, so they say. But once again, its all based upon assumptions, E85, E80 and so on.

All EU people using metrics should just use the std data log setup for help or advices . Thats what everybody uses here and is comfortable to look at.
