The ECU needs always adaptation.

[cleex024]

hey guys...i recently installed my downpipes and changed maps to stg2 not +fmic. i thought this would make more power than the oct93 aggressive, but it seems like im creating less power.

i dont know if this is all due to linear throttle vs whatever throttle they have, but seriously the difference is huge where oct93 would wheel spin its ass and stg doesnt not.

also you guys think it would be ok if i strap exhaust pipe fix tape and pull the dps and mid pipes together so they dont clank against each other...the dps are now so close together that they clank when under load or stopped at a light.

From what i've read you're right about the P2AAF code, but i've never got that code. I've been running the Cobb tune for months(and thousands of miles) with zero issues; except for having to change the plugs to run stage 2+ but thats the plugs fault, not the tune's.

Never hear that before about driving around a couple of hours to adapt.A flash is instant it will get minor changes after a couple hundred miles of driving.

The difference between stage 1 and stage 2+ was very significant for me on my first pull (second pull not so much as it blew off my chargepipe). I dont know how you couldnt noticed it.

Also, what type of dps did you get and who installed? I have never heard of them making noise hitting eachother.

With a flash tune the car needs to drive about 100-200 miles in order for the DME to be "fully optimize" to the new founded power

When I flashed to Dinan S3, a day later only after driving 60 miles, I had a friend using JB4 map 5 on a 135i, he walked me. 3 Weeks later, way over 200 miles, we met back up and I walked him everytime.

The DME goes through an adaptation period.

Edit: Not saying you will not feel the difference right after the flash, but it will get even better after couple of miles....

please read it again...i said NOT stg2+fmic. from stg1 to stg2. damn i hope my charge pipe doesnt blow off once i get fmic...guess i should just go ahead and upgrade my chargepipe while im at it.

also about dps i have installed the new vrsf ones and i accidentally put it on about 3mm clockwise so it is that much closer to the other downpipe. the space inbetween the 2 are about 2mm and they just clank against each other when there is movement in the pipes.

anyway anyone think its ok to strap them together?

ive driven on it for about 300 miles with it and then reflashed to stg 1 and instantly had more torque...i mean you can peel the wheels again. in stg2 i was not able to spin the wheels at about 2500 rpms like i was able to in stg1.

Makes More sense now!The way you described it is how I understand how it works .

I think
The first stage 1 maps were very aggressive and cobb tuned them down a bit !

i dont understand...why would the stg2 be tuned down farther than stg1? im running the new stg1 vs stg2.

i swear it seems to be the linear throttle cause even stg1 with linear throttle seems like it sucks. but the stg1 thats not either stock or linear throttle seems to push so hard.

cant wait to get fmic i guess so i can run the same throttle in stg2+fmic...cause in just stg2 there is only linear throttle.

For your dp's, go and fix the 3mm you said so it will be farther apart.. My AR dp's are super close but they don't clink. And I don't think your charge pipe will blow off with a FMIC but you will feel a bigger difference.

yeah but the only problem is i have to take everything apart agian and that would take at least 2 hours to fix...because its the pipe on the driver side.

Stage 1 203v stage 1 was over aggressive to many.If you want to run a much stronger map ,then have someone email you this map.The linear fools people
In thinking the map feels weaker then the stock throttle.All it's doing is making the throttle do exactly how you pres it.Stock throttle hits 75% at 20% throttle so it ramps up the Turbo very fast ,for a a explosive wot feel.Now stage 2 + is violent when compared to the rest .good luck .

haha thanks...well i hope i dont blow up my engine lol.

ive been reading up with that whole m3 supercharged thread...its getting kinda crazy. that better not happen to my engine lol

Thats not too bad? haha

cleex...if i were you i'd spend the two hours to get back up in there and correct the position of the pipes. the two pipes should not be touching each other...so i wouldn't recommend strapping them together...that's just a bandaid fix.

also...linear throttle vs stock throttle maps are night and day...at least that's the way it feels to me. i ran the stg2+ fmic linear throttle maps for a while before the stock throttle maps were released.

Hey Everyone,

I recently bought the Cobb AP for my 2008 e90 non sport. I flashed stage 1 aggressive 93 and absolutely love it. Over this past weekend I installed the Turner Motorsport boost gauge and noticed a drop in pressure once the car fully warms up (200). When the car is around 160-180 degree the psi goes to 14 but after is warms up to 200+ the psi drops from 11-12. Is this normal? Any ideas why this could be happening? Thanks!

you should not go WOT when the car is not fully warm.

Thanks for the response. I usually do wait for the temp to be above 200 before I drive it hard but these few times it was at 180-200 when it hit 14 psi then dropped off to 11psi once it was over 200 in the 200-225 range. I am just worried I am not getting the full power or that something is wrong. Maybe Cobb stage 1 aggressive normally operates at 11psi?

log your car when fully warm so we see whats going on . You could use Virtual dyno to trace boost and AFR . The new VD has as well a plotting functionality

[Streetsweeper360]

210 would be the minimum to go wot!

Do you have any mods aside from the AP? If you have bolt-ons the car runs less boost on stage 1. It could also be due to the cold weather making more power so it needs less boost to hit the load target.
