I tried stage1, but was disappointed in drivability (boost came on waaay too quickly for no reason... even with the stock throttle mapping) and power compared to my JB4. Things got even better with 'auto-learning' (map 5) on the JB4, while I waited on Cobb to release a stage2 map...

I'm wondering how stage2 compares. I'll most likely flash it tonight, but I was hoping for some information to hold me over.

I ran the Cobb Stage 1 tune on my 135i, which was full bolt on. Now, running stage 2+ on the 1M full bolt on, is much smoother, and obviously more powerful. Yowzers!

I saw 21 lbs, but only for a second...and only once. Usually 19lbs to a solid 18lbs there after. Of course it tapers a little towards the top of the RPM range.

Honestly...its kinda hard to look at the P3 when on the gas like that.

When I ran early Beta I would hit 19s regularly, which was...concerning considering it was on an all-stock car. And it's also inefficient, you get nothing out of running such high boost on stock turbos/DPs/Intake/FMIC, other than stressing the turbos/engine needlessly. Which also explains why I didn't run it much on those type of settings. Spoke to Cobb a few times on this matter, they've 'turned' it down a notch or two since then.

For those who haven't tried out the 4.02 maps yet, I highly suggest you give them a shot. Very smooth map.

There's been like 3 firmware updates in the past 3 days... Anyone know what they're changing? No release notes. I suppose you have to re-flash when there's firmware updates? It isn't technically a map update...

So cobb rewrites the dme boost table now too if max boost is over 14.5psi?

jackkk · 12-20-2012, 03:15 AM

Did someone campare Evolve and Cobb?
As I understood the Cobb linear map is more interesting for a DD + track, because it has no turbo lag, but if you run the stock trottle the turbo lag take place?
Didn't really undestend about the M button, it functiones only with the stock trottle, which has turbo lag, or it is still availavle in linear map?
How much PSI does it go on st.1 and st.2?
Did some one has any Check engines ore some other problems with the Cobb?

I have been more than satisfied with how Cobb has been performing in my car. That timeslip was strictly on 93 octane, but now I have bumped it up to the race maps and my best time is a 12.078@118.20 with a 2.072 60ft. This was done on stock runflats, so I'm sure with better tires, running 11's would not be out of reach.
