Stock throttle to linear throttle COBB

I just switched from the stock throttle to the linear throttle map, stage 1 agressive and I really like the drivability around town. It's much easier to ease into the power. The stock throttle seemed very on or off. On the highway I'm not sure, the stock throttle is great at 80MPH in 6th gear.

I really like this COBB product, I'm looking forward to the stage 1+ because I think in intercooler is next.

A throttle map in between linear and stock would be interesting, if you guys in Texas have nothing to do and want to graph these two together is would be great.

I would agree with that... the Stock Throttle was a bit too much for me... I feel like you start hitting 18psi at 25% throttle pressure. Then I tried linear throttle, which I liked a LOT more, but it's like you have to push 85% throttle pressure to get the boost going...

Anyways... I'm not THAT picky... I just adjust the way I drive and I kept the stock throttle on... there are other things I'd rather them work on anyways (*ahem* METH *ahem*)

hmm, I actually found the opposite. I've used stock throttle for a while and recently tried linear, and maybe it's just not being used to it, but it feels really odd to me. hard to rev-match even though I usually don't even have to think about it..

I find I need to give throttle curve changes time to settle in with my brain after being used to another throttle curve.

Cheers,

Yep, I also tried linear but switched back to stock. The linear was nice, and I'll be the first to admit that I probably didn't give it enough time to get used to it, but I was so used to the stock throttle that the linear felt like driving an NA to me, so I switched it pretty quickly. Maybe one of these days I'll give it another shot -- seems a lot of people like it a lot.

yup, it's gotten better after some time, but I think I'll be back to stock throttle again soon.

Anything below S2+FMIC performance; Linear = Manual, Stock= AT and thats that.

I mentioned S2+ because at those levels, stock can be too jumpy and not as smooth.

Some people like aggressive drive, some people like smooth. It really depends.

+1... I'm on S2+ aggressive and the stock throttle is way too jumpy for me... Linear throttle is vastly more controllable and comfortable in the road for me.

To me the throttle feels more response with the linear tune, stock feels sluggish. I keep switching between the 2, I wish I didnt have an option

Currently running stage 1 sport linear.

I tried the linear throttle map for 6 months or so, then switched back to stock again. I decided that I like my on/off switch.

Drive Modes

2007 335xi AT (fully stock atm).

Anyone else on stock try the Drive + Stock or Linear Throttle settings? I can't really tell any difference.

I was going to be good and wait a week or two before moving up through the profile, but I think I probably have to put it into Sport + Stock Throttle before I feel any difference?

It might be more difficult to tell in an auto, I dunno.

There is a VERY pronounced difference between linear and stock throttle though. I find linear is much more predictable regarding power out of corners and when launching.

I have an AT and I tried going to linear a few months back and it is definitely a more drivable map for daily use around town. However, it lacks that throw you back in your seat, fun factor that I love about my first turbo car.

Interesting, i just ordered mine off a member. I'm going to try both. When you guys say linear feels like N/A do you mean in terms of like a honda getting off the line or more so their top end? Cause I think a rsx is more responsive than an evo9 off the line, but the 335i is more responsive off the line than the evo9...then again these 2 dinky turbos were basically the same size as my single in the evo lol...if stock throttle is what gives you that push back in your seats I'll leave it at that though.

I just ordered my cobb ap as well.
Could you care to elaborate the difference in Linear Throttle and Stock Throttle?
Right now I have JB4 G5 running map5 and throttle feels aggressive but also good for daily driving. Which cobb map is similar to JB4 G5? Linear throttle or stock throttle? I just want to get a glimpse of difference between the two.

Hopefully I am explaining this correctly but the boost is based on throttle position. With the linear map, the boost gradually builds based on pedal position. With the stock map, the boost comes on strong at about 30% throttle.

At least this is what I feel when I drive stock versus linear.
