Cobb 3.01 Map Log Chart

[sluflyer06]

Just got the Cobb yesterday morning after deciding to switch from a piggyback. Ran this log on the 3.01 Agressive map to see how it looked...I'm very happy, doesn't appear to be any evidence of knock from my fairly untrained eye, I am a little surprised boost doesn't hold to target although I'm not sure if the car is trying to...does target change with IAT? I looked at WGDC and it doesn't increase as the boost delta increases.

Overall I'm very happy I was getting large timing drops with the piggyback (3-5*)

From the log and thier new mapping ,seems like Cobb lowered the boost for **...I think they did this to keeP the turbos frOm Over spinning and * plus boost combined makes great power..The log looks vet good,how does the car feel up top?? Does it feel stronger then the piggy?

[sluflyer06]

I'd say top end is probably similar or slightly better but hard to say, what feels (to me) signifigantly improved is low and mid range torque and response with the Cobb, scenarios like part throttle ~3K rpm just feel fantastically strong with the cobb.

I believe a FMIC will be a perfect compliment to this type of tuning and its on my list in the very near future. I"m just stoked how happy the motor is compared to the piggy, I'll make a dyno appt. soon and we'll see how the Cobb does compared to my 'no tune' baseline run.

as per cobb, they re-configured the output voltage for the 2.5 bar map sensor above 5500 BUT they havent updated this in the datalogging software. Boost above 5500 is actually higher than what the logs show. They are going to reconfigure this in the next firmware update so actual boost will show up in the logs and realtime data
If i were to guess id say that actual boost is pretty close to the target boost above 5500 rpm!

Is this 2nd gear? I bet you'll be closer to boost target in a higher gear.

The gearing lets me stay in 2nd when autocrossing on larger courses that put some other cars in 3rd, but I definitely notice power tanks hard past 6k. It seems to tank less drag racing when I go through the top of 3rd gear. That's pre-v300, but I doubt much has changed.

I could hazard a guess that there is a WGDC upper limit that is being hit and that explain why you don't see WGDC increase. Hopefully Cobb will release RaceTuner some day and we'll be able to actually see what kind of maps are available.

Check the post above you, which confirms what I was told personally by Cobb about boost readings above 5,500. I'm not hitting a WGDC limit and the fact that WGDC remains fairly steady above 5,500 also lends to the fact that i'm prolly actually at the target otherwise it would be rising to try to hit targets..the car certainly doesn't feel like boost is falling off up top . Also judging by the fast rate of IAT increase i'd say they're working pretty hard up top.

Get a good intercooler this will help you..I would just not get a helix.

[sluflyer06]

Do you have experience with the Helix? What was wrong with it? I was looking at mostly the Helix, AA, HPF.

He doesnt like helix because I called him out on his endless rant of knowitall BS he spouts on this and e90 post, you can read the hysterical thread here:

As in most internet knowitalls, he's all show and no go...just a troublemaker not worth anyone's time, yet again causing problems in perfectly good threads with useful information that shouldn't be derailed. He's a troll ignore him, look at some of his posts to gain insight on this subject!

Honestly I don't like the stepped core design at all,it doesn't even come with piping or any other sort..the aa is made in china and requires a good amount of cutting to the bumper..The hpf is not impressive either ,it uses stock couplers and clamps which makes no sense ..if you take off the stock piping you'll see how restricted it is..I went with the er and I'm very happy!! The fitment was the best the shop has seen,and the fitment was spot on..it has to be trimmed ,but not much..the core is really thick and dense ,and the car feels stronger pull after pull..I noticed a big jump in the mid range power band,plus I got the black anodized for a complete sleeper look!! Trust me the er is the way to go!!

Lol .. Your the one who trolled on my thread about your core,I never invited you !! Everytime I see a intercooler thread you pop up !! Give it a rest I will never buy core from you !! Good day

[sluflyer06]

I think stock couplers makes alot of sense if you want to be able to remove it easily. While my car is an 08' its only got 15K miles and under warranty until mid 2013.

I've been so focused on tuning issues I haven't seriously researched intercoolers yet, its seems like they all work but vary on features, fitment. I plan on installing it myself so one that isn't overly involved without a lift is ideal and I'd prefer not to remove the bumper.

I'm not going to derail this useful thread on YOU, if you have anything to say pm me or meet me in person I live probably less than an hour away

Back on topic!!!

Don't be worried about a little cutting or removing your bumper, the shop had it off in 10 min!! Look into the er and look at their r&d!

[ken1137]

You two again ?!

Sluflyer6...yes, an FMIC should be next with your Cobb AP. I went with Forge b/c the local shop sells it and I trust them (WSTO).

Here is a quick review I found; www.e90post.com/forums/showthread.php?t=329764

So are you saying that NONE of these other IC's will make the car feel stronger pull after pull? Did you notice a big jump in the mid range with other IC's??? I don't think so...I have the HPF IC with those "Stock" pieces you spoke of....the cars drives great....to semi-qoute you "HPF is the way to go!!" Anybody can come on here and say that stuff man.

[MilehighM3]

Any IC upgrade is going to help you out, period. The more heat soak you're getting, the bigger the core you should consider. Also try to be honest with yourself about the end of your modding road and where you want to be. I've seen both good and bad ER cores. HPF is nice, I love my AA.

Bottom line and back on topic, your log looks great to me. Since it says 3rd gear along the top, I think that answers another question asked as well. :-) I'm getting ready to ditch the piggyback and go with it myself. Cobb makes a great product, easy to use and good power for not a lot of money. I'm just waiting for a few more features to become available before pulling the trigger. Unless they need high altitude beta testers! ;-)

[thebigragu99]

Yes this is true ,any intercooler will help vs the stock core.
