Cobb: First Impressions...

EastCoast335i · 07-26-2011, 04:56 PM

Just finished installing the Cobb AP Stg1 93oct (6MT, bone stock) (previously JB3 map5).

Drove around the parking lot for a bit to make sure everything was working. I'll get to test it bit more tonight on the drive home.

First impressions: Driving around the parking lot (5-25mph) the car builds boost very quickly, almost too quick. Like theres no partial throttle. Again this was a VERY limited drive so the jury is still out.
Definitely feels like it'll be faster in a straight line compared to the JB3 map5.
Drivability ??? time will tell.

I will stick to stg 1 91 oct on really hot days specially if your bone stock and the difference is not that much anyway, I prefer 91 oct over 93 oct for daily driving.

I'm going to keep it on 93oct map for the near future... I want to see how solid this tune is. From my understanding this tune was made/tested in Texas so if it can handle the heat and humidity there our temps should be a non-issue...

Only logs can determine if 93 octane map is too aggressive. Eitherway I here great reviews on the Cobb. I hear top gear solutions has the best price.

Cobb is the

Wow, im really impressed, after further driving the power delivery is very smooth and just keeps pulling til redline.

I'm going to run a few datalogs on my drive home tonight, but from glancing at my boost gauge car is maintaining about 14-15psi of boost throughout the power band.

I can only imagine what Stg2 will be like.

N55 or N54?

Not really the throttle mapping and boost control is horrible for anyone that prefers a linear throttle.

Jury is still out for me, but so far I dont think its any worse then JB3.
Are you AT or MT?

I assume you're using the new 2.03 map? I am finding it to be a bit more refined (even though there werent supposed to be any changes for 6MT cars) than the 2.02 map was...

I was having problems with throttle closures with the 2.02 map - really annoying. As far as I can tell, that's gone with the 2.03 map. So far so good, although the standard 2.03 map is still really non-linear when it comes to throttle mapping. I haven't tried the 2.03 alternate v2 yet though, because I hated the previous version...

I've run the 93 octane map 100% of the time this summer and haven't had any problems even with the stock intercooler...not that I try to do a lot of WOT pulls back to back, because I don't lol

I just got mine as well, and its smooth.
V203 maps btw.

No I actually got rid of the Cobb AP and went back to the Procede. The last maps I tried where the 2.02 variations.

That is good to hear though they are getting that throttle sorted out.

6 speed manual. I think the autos had less of an issue with the power surge.

I started a thread on this a while back with some logs.
