Looks ok, but it's always easier for me to read the actual numbers in a .csv. You do have a throttle closure around 4200, though.

No problem! Everything looks pretty good, except you have a throttle closure at the beginning of the log (was traction control off?), and you have a slight one between 4100-4350, which you can fix with ATR if you log MAF req (WGDC) and boost setpoint factor. Everything else looks good to me.

I'd love to get some free sparkplugs and injectors though so if I get that for 50 bucks + the $13 techron I'm cool with that That said after how bad that last log was I'm probably done ever trying it again. Funny that BMW also sells the same cleaner rebranded.

Yeah man. Techron is not that bad. A friend ran it in his M3 and it seemed to be ok

I think I forgot the traction control on!

Everything looks very good with the exception of the overboost that occured at ~4000rpms in second and then reoccured both times immediately post shift. That can be easily fixed with just a little tweak to the wgdc base table, though.

Thanks for your time.

How do I go about that?

Download ATR from Cobb's website and then give this thread a read. If you have any more questions just ask.

Yes sir, i went for a ride in rader1's car and all i can say is wow. Even on "low boost and timing" it hauls ass. On meth my car feels pretty good but I can definitely feel the turbos are straining to make power at ~6300rpms(where i shift.) With the stage 2s it just feels effortless and the powerband is so WIDE now it's unbelievable. I can't wait for him to really push those turbos, i think he's just waiting on a couple goodies to arrive then he'll hit the dyno.

As soon as the turbos are officiallly "released" i'll place my order.

that's good to hear. I was in contact with rader last week as well and we chatted back and forth for a while. It seems he is pretty impressed and happy. I can't wait till he turns it up as well

If I still had my FBO + METH E90 I would have placed my order as well. I really wanted a coupe for a long time and pulled the trigger on a 2010 E92 so now I'm stuck at stock (COBB only, with my own E85 tune) since I have factory warranty. We'll see how it goes.

why not stage3s ?

LOL cobb is the best plus the dme knows alll of it so totally safe.

[Ænema]

IMHO stage 3s will require a COMPLETE overhaul of the car to make the most of them. BBK, suspension(at least replacing all the OEM parts with new M bits), clearancing the rear to fit some WIDE tires, rear lock down kit and probably stuff that will break. It's a little more than i want to spend/get into right now.

OH I agree for sure! I wasn't complaining about the tune at all. just saying that I wish I had an intercooler and DPs. well at least an intercooler.

I started with an E30 tune (92 pump), running ~15psi midrange (I don't feel like pushing harder on stock hardware), and 13.5 deg of timing up top. it seems clean to run.

IATs are killing me though, I forgot how crap the stock IC is. I'm going to ramp up ethanol and try to help my top end further.

Yup, it's definitely calling us though. I got a very low mileage car with warranty so I have a reason not to mod lol we'll see how that goes

hey everyone
i want to upgrade to stage 2 turbos.

RB or VTTO stage 2

of course without methanol either 91octane (95euro) or 93 octane(98euro) depends where i am located

my mods: cobb ap , downpipe , cold air, and 7' intercooler

is it worth it and which one should i go with ?

kifak man?

I think you should wait to see how the VTT Stage 2 perform. For now results are really promising.
to really make a difference and to make it worth your investment you need methanol or E85 (or both ).
I remember how crappy the gas was in lebanon man, 98 mish 3azim ya3ne

haha kifak bro

the thing is some saudi guy is willing to buy my stock turbos since his car got into an accident and he needs 2 turbos.

i ship my car to lebanon time to time. thats when i have 98 or else in saudi there is only 95

if im not willing to get methanol, its not gona make a noticeable difference at all ya3ne? or should i just go for it and later on maybe i decided to fit a methanol kit .
and your right about the gas in leb haha constantly changing fuel pumps on my sisters e46.

it would make a difference but the top end you;re looking to get will not be achieved by Lebanon's piss gas

Why are you against the idea of water methanol? It will be magic over pump, take my word for it.

The other thing you can do is tune for ethanol. Buy ethanol and add to tank hehe. I use E85 here and it's night and day
