Thanks

We should have that document available once AccessTUNER is released.

it's ok - at this point if they can pick up 20-25hp and 20-25ftlbs with a protune, i'd be pretty happy.

still trying to keep my full stock exhaust lol.

AccessTUNER = Protune ??

Cobb guys -

Have you seen any logs using your "Aggressive" (93 octane) maps with 94 octane (up to 10% ethanol content)?

The 94 w/ ethanol is readily available in my area. For Evo's and STI's (what I've had direct experience with), it has allowed for more ign. advance and boost (using ATR), but I was curious if you guys had any data specific to the 335i. In other words, do you have logs showing 94 octane with 10% ethanol is within the parameters for the 93 octane maps.

If not, I'll have to do some testing.

You may see less timing drops across all cylinders but you won't see "more timing" on the ots maps. Once ATR comes out you could tweak the ignition tables or load targets for 94 octane but I doubt you'd see a difference on the canned ots maps.

Not quite what I was asking haha. The ECU can't add timing by itself, beyond requested. But, I can understand why what I asked could be taken the wrong way.

I should have rephrased my question - is 94 octane gas (spiked with 10% ethanol) suitable for the 93 octane maps? I'm erring on the side of caution thinking that maybe the logs (if they exist) suggest that the 94 w/ ethanol is more like a better 91, but not like a true 93.

In other words, is 94 w/ ethanol less awesome than true 93, and therefore should I stick to the 91 maps when running that fuel?

Sorry, a lot of words trying to ask a simple question

Most 93 nowadays is 10% ethanol. I always buy fuel at one of two places: one is 10% ethanol and the other 100% gasoline. I haven't seen any difference between the two as far as timing drops go. But the best thing to do is to do some logging for yourself.

If the protune qould be able to extract that much more,then who needs meth if you can make 440 -450 tq all day on pump.I heard that a cobb stage 2 + aggressive on a fbo completely catless make 418 all day on pump gas..this true?

I feel the power difference on 10% rather then 100%pure.

Lets just say S2+ FBO would trap 117-118 all day on pump. These things dont dyno as good as they actually run. all dynos ive seen are around the 390whp dynojet, a bit less on a mustang.

There's a dyno over on 1addicts of a stage 2+ car putting down 420rwhp. But im almost positive thats either an optimistic dyno or a dyno operator skewing the results.

well, i made 326hp and 390ftlbs on their mustang dyno in Austin back in 90 degree weather with just Stage 1, DCI and ETS.

if i can make 345 and 410 on that same dyno i'd be pretty happy, which is why i'm asking if simply getting protuned would net those numbers since stage 1 technically is not "mapped for my intercooler".

They made over 400 wtq on Stage 1+ on that dyno.

Why don't you go dyno instead of speculating?

[elim11]

What psi does Cobb stage 2 drive maps run?

[RaihaX]

I have just changed camp - waiting patiently for my cobb ap to arrive!

The 1 series makes more power then a 335i.The 1 exhaust is a bottle neck,when the rear cats are removed it makes 15 whp easy.The 335 doesn't see that gain cause the oem exhuast flows better then the 1 .Yucci made 417 whp and 466 tq on a sae dynoject on straight pump 93 oct.The jb4 is fairly weak when compared to the cobb.The stage 1 aggressive feels stronger thhen the map 2 jb4 any day of the week.The jb4 gets more worried about their afr's.Richer=more tq and a cooler running engine.

This post leads me to believe you don't really know or understand allot about tuning...

Ultra 94 is good to use with the aggressive maps - equal to or better than a 93 with ethanol. I would venture to say nearly all of 93 in the US has up to 10% ethanol in it anyways. You are good to go.

^Thanks for the responses. Time for a reflash

Is this a troll post or are you serious?

No. The 135i's dyno LESS in stock form than the 335i cars. Reason is the 135i exhaust is more restrictive than the 335i, so why would they make more power? If you mod the exhaust, you would just be getting power back that the 335i already has. This is why cobb states it is okay to run their tune on a 335i with stock exhaust and not okay to do the same on a 135i with stock exhaust.

Yuchi is a personal friend of mine, So i'd know better about her car than most people on here. I have JB4, DCI, fmic, and downpipes. I was on map 7 (98 octane and 16.5 psi), our cars are very similar in terms of speed with her maybe edging out way up top. Her 135i has the same mods as my 335i, except she has an aftermarket catback exhaust and is running the COBB stage 2+fmic aggressive tune on 93 octane. Her car hits about 18 psi. So by no means is the JB4 "Weak" as you claim.

You also claim that terrys customer service is bad. He helped you by referring you to links with all the information and suggested solutions you needed to resolve the problem you had. He isn't superman. All you had to do was READ. So because you didnt feel like reading or putting a little effort towards solving your problem, his customer service is bad? Nah, I don't think so.

Also, stop bashing tunes after you buy and then sell them. If you dont like a tune , fine, but dont go out of your way to bash or emphasize how "bad" it is to you.
