More AP maps?

Anyone know of addition maps from cobb for different setups? they have no other maps for stock turbos + other bolt on's..

i have a 04 wrx it had TBE, upipe before i had cobb and switching to stage 2 map made a WORLD of difference car runs so much happier now and no more overboost

Other bolt ons such as what? A protune will and is much better than an OTS map. The OTS maps are generic and made for safe driving till you can tune it.

hks up pipe

invidia bell mouth down pipe

hks catback

perrin turbo inlet

spt short ram intake

15-17lbs via MBC witch i want the tune to control n get rid of the MBC

My boy got his 3rd gen RX-7 tuned today, so i got to talk to the tuner there. he said with the stage 2 map (turbo back exhaust) it shouldn't have changed too much with the other addition bolt ons. proly just need a little tweaking i guess we'll see i should be going tomorrow to get the tune.

o and the rx makes 325 right now.. some ignition issues at the moment. # should go up..

OK so i got my protune today.. i was kinda disappointed with the #'s but i guess what can i really expect with the stock turbo/fuel sys. also the car was running fine with the stage 2 map from cobb very minimal changes were required... but did find out the MBC i was using was total crap.. boost going up down up and down again so thats coming out, putting stock solenoid back on and having tuner put it @ 18lbs altho he had me boosting 19-20 on the dyno says thats fine... seems a bit high to me..

so she made 250 HP and 285 torque @ the wheels i guess thats not so bad... was expecting more since ive ran with cars putting down 300 and are lighter i guess my driving isent too bad.

stock turbo falls off terribly i end up making 175 hp by red line... awful lol i think its turbo/fuel time.

Why are you going to put the stock bcs back on... do you think THAT's the limiting factor ? You can test your bcs. Do a search on NASIOC (I can't get on there, otherwise I would have given you the link)

no, only reason for going back to stock solenoid is to get smoother boost with out the fluctuation.

Then look into spending a little extra (if you can) and get a 3 port BCS. Since you will be going back for a tune. This will help build boost fast, hold longer and is much better than the stock unit.

hmm i thought it was just the tiny turbo size that wasn't able to keep boost levels up. Im not sure how a better boost controller will keep boost levels up, just steady correct? Whats so great about the 3 port bcs? I see a prodrive for around 100 bucks..

my boost basically screams up to 18lbs @ 3,500 then falls off all thru red line

CobbTuning.com - How Subaru’s Factory Boost Control System Works

That might help explin a little bit there. No you cant just plug it in and go, you hav to tune it right away.

I wasn't asking how the boost control sys works, I was asking why you think 3 port BCS would be able to hold boost levels up for longer.. I also dident suggest throwing it in with out setting it up either. you ok? lol : )

now im not sure why but few years back when i put in my MBC i had the stock solenoid still hooked up, lol so i capped that off (stock solenoid) and ran MBC properly now. it seems to not fluctuate like it did b4 but it does increase max boost level with each higher gear...... 2nd 17lbs 3rd 18-19lbs 4th 20-21lbs annoying!

Some of that is the turbo and some of that is your stock fuel system and stock intercooler. With more fuel and better TMIC I could do 15psi at redline but when winter hits my IDC's get to high so I run 13psi at redline. This also very much tuning to the limit of the turbo. 3 port BCS will give better spool up and for those having trouble with holding max boost or hitting target then a 3 port will help as well.Some people hit only 16-17psi with 100% duty cycle on the stock BCS. I hit 20+psi(midrange of course) with only 65% duty cycle on the GM solenoid.

well my setup has no problem boosting right up to 21lbs (then quicky falls off). My main question is How will a 3 port bcs keep boost levels high for longer? as suggested by newtothegame, or witch boost control system will best control max levels. as i wrote in the post above with each gear my max boost increases forcing me to lower levels in 1st n 2nd so 3rd n 4th wont over boost.

Because the stock BCS is a "bleed" type system while the 3 ports can run as a "hold" type.Bleed type systems sometimes can not bleed off enough air at higher rpms to control boost properly

Thats normal.I run 20 psi as my max boost.There is no way I can possibly expect 20 psi in 1st or 2nd gear as boost is load dependent.The JDM ECU's actually have wastegate duty compensation per gear which allows you to tune max boost for 3rd gear and add compensation to 4th and 5th to keep overboost from happening as those gears can hit higher loads much earlier in the rpms especially in colder weather.

so the 3 port will or will not help with over boosting in 4th 5th?

will any MBC be capable of stopping that over boost in higher gears?
