Default A more practical use for the S and S# mode

I am not sure who brought an AP for their car drives in the S mode instead of the S# mode....(I drive in the S# mode all the time)...so having the means to switch between 2 different maps (using the dial in the center console) for the same type of fuel really does nothing for me...

I thought a more practical use of the ability to switch between 2 OTS maps could have been done with S mode (when it uses 91 octane map) S# mode (when it uses the 93 octane map)....now that would be useful when I cannot find 93 octane fuel nearby.....What do you guys thinks ?

How many of you uses S mode anyway and when do you use it ? Just want to figure out if I am missing some usage model of the S mode....

Acessport doesnt do this but Ecutek RaceRom will.

From the factory, SI-DRIVE impacts the drive-by-wire throttle mapping (requested torque). Besides the throttle verses accelerator pedal relationship, this will potentially impact boost control as the boost target table uses requested torque as an input. There is no provision for separate fuel/timing at least as far as how it is set-up from the factory.

Certainly, though, this is a type of capability that could added by manipulating the factory ROM (as we have done for other features like real-time tuning and LC/FFS). Although we have not decided either way, we have thought about the possibility of some type of map switching via SI-DRIVE. We welcome any opinions or ideas that anyone may have.

With an AccessPORT, you can change to a map for 91, ACN91, E85, race gas, meth or any other custom fuel with a few quick clicks of a button. Or you can upgrade and add a new feature, such as LC or FFS. With the other options on the market, especially the one you mention, the end user is limited to whatever is flashed to the ECU (IE, fuel type, boost levels, etc.).

Lance,
Ive owned two subaru's an 06 wrx and now and 09 STi, both cars were protuned with an accessport, and thats all i'll ever use, I don't like how Ecutek locks you out of yer own ECU. Cobb's software is second to none.

I was just commenting on the OP's question regarding S and S#. Ecutek has developed a RaceROM software, which is just a patch to an existing Ecutek license on yer ECU. It allows for speed density conversion as well as a 3 different stored maps on yer ECU at any given time. Want more timing for a better gas? Switch to sport sharp, want a stock map for the dealer? put it in I, etc...Also offers FFS/LC

As Lance mentioned, the AccessPORT allows you to switch between real-time maps very quickly. Each real-time map can include changes for boost, ign. timing, fuel, AVCS, injector scaler (useful for E85), etc. You could have up to 100 different maps on the AccessPORT that you would have access to.

Changing "maps" via SI-DRIVE knob is something that some of our customers have requested. We haven't made any decisions on this yet, though. Speed density is something that is currently under development.

I would love to see a real difference in boost/timing between the si-modes... make sharp mode really "sharp", lol. I really think cobb should take advantage of what subaru put on the console...

^ you can see a real difference in boost.

subaru put it on the console, but didnt provide a way for timing or fueling to be adjusted.

i really thought that the 2011-2012 models were going to have fueling, timing and avcs as rpm vs requested torque.....that would allow it.

Don't the most current Stage 1 OTS '08+ STI maps ("Boost-Select") use SI-Drive to toggle different boost (16 vs. 18 psi)?

^ yes.

but the op is requesting using it for 3 completely different tunes like 91 oct on econo, 93 oct on sport, and e85 on sport sharp with the ability to remap all parameters and not just boost.

With my turbo upgrade and tune at Agile, Hill set up somewhat different maps on each SI-drive mode: intelligent at 14psi, Sport at 18psi and Sport# at 20psi.

Intelligent mode is not fun at all and I barely see any difference in fuel economy. However, when my friend had to drive my car on a road trip, he almost ran us off the road in Sport so we switched it to Intelligent for him. Much better.

Sport is fun, but Sport# now takes your pants off. My wife gets pissed when she sees me switching it to Sport# cuz she knows what's coming next.

The other advantage of three modes is engine note. When in my neighborhood, the exhaust is a little quieter when in intelligent mode. Just slightly, but any little bit helps.

Overall, awesome set up. I'd be interested to hear anyone elses experience with different maps on the SI-drive.

haha, thats how it should be done. loving the bit about your wife getting upset. So for you, is there any advantage to having intelligent at 14 psi? because if its the same mpg, why not leave it in sport+ so you have the power available...

The only time I put it in "intelligent" mode is to keep the exhaust note down a little in my neighborhood. I could just ride lighter on the gas but its much easier just dialing the switch. Otherwise, the fuel difference is so small, I just don't feel like its worth it. It's almost like "valet mode".
