Profec B control box - where to mount
I am trying to find a place to mount the rather large black plastic control box for the Profec B (not the one with the ***** that goes in the glovebox). Anyone who's installed a Profec B or other EBC have a good location under the hood for the control box? Up by the headlights? Under the washer reservoir maybe? TIA.

Just want to let you know that my car is running well with the Steve R chips again...I dont know what was up...but the 3 bar fpr is back in and 16.5psi of boost dialed in...car runs strong, no problems. I replaced the AFM and adjusted the TPS/throttle stop a little...maybe that had something to do with it.
Anyway, have no fear..steve R chips aren't garbage like I thought they were.
Should have some dyno results to share in a couple weeks.
Onto your question:
How about in the space next to the battery box, by that big black plastic cover?

Thanks for the update. I was seriously worried about that! Now, I'll go ahead and put 'em in... :-)

I actually looked at that but the windshield seems to point rain right onto the top of the box... I thought there might be a better place. The location under the windshield bottle looks ideal, but more work (and hose and wire) to get it there. I'll take a closer look at that control box. Maybe I can silicone the seams to make it (more) watertight and the battery box will work fine. Thanks again for the "3bar" update!

I also installed my profec b black box under the plastic sheald next to the batery. It seams to be keaping dry and away from heat.
What setting are you guys using for the wastegate ballance and switch's in the back?
Mine is set at internal wastegate,max ballance and i get great boost controlle but im not sure if it better to have it set higher or lower on the ballance.
Also i don't get why when i put the wastegate setting to external i can't control my boost?
I remember adrial having the same problem as me,did you find a better setup?
And sometimes i hear my wastegate open from 0psi to 4psi then close and re open when i reach 16psi, when i'm accelarating, is this normal?

I haven't installed it yet so I can't help yet, but GReddy's technical phone line is (949) 588 - 8300. I have their number just in case I need it during the install.

Hmm I'll go ahead and hijack your thread kind of, also letting you know some recent test results
Steve R @ 16.5 psi, 45psi with vac line disconnected... 60-100 in 6.6
autothority stage 2 @ 18psi, stock fuel pressure, 60-100 in 6.2
I have a strong feeling that I'm rich with the steve R stuff...but if I dial down the fuel pressure I get running problems...I'm gonna replace the fuel dampner next I think.

"Mine is set at internal wastegate,max ballance and i get great boost controlle but im not sure if it better to have it set higher or lower on the ballance.

They (Greddy) really should re-write their manual and change their terminology. The reason you have to choose the internal wastegate setting is really the difference between a single-port versus a dual-port wastegate.
The single-port is like the one that comes on our car and uses a single hose to feed boost-pressure into the diaphragm. This then pushes on the wastegate valve and opens it. This also happens to be the way most turbos with integrated wastegate works.
A dual-port wastegate on the other hand, uses vacuum to open instead of pressure. Most likely when you go to buy an external wastegate, it will be of the dual-port variety.
So during the boost-control and wastegate activation routine, the boost controller would send a pressure change of 0-15psi to the a single-port/internal wastegate to open it. Meanshile, with a dual-port/external wastegate, it would need to reduce pressure 15-0psi on the control line to open the wastegate.
It just happens that our wastegate is of the single-port design, even though it's mounted externally. So you need to select 'internal' on the Profec unit to get it to operate in single-port mode. They really need to fix this nomenclature problem and use the real terms of single- or dual-port wastegate. But then the rice-boys won't be able to deal with it because it's not as simple as internal & external.

Thanks Danno <img src="graemlins/bigok.gif" border="0" alt="[thumbsup]" />
It's great to know i'm not running it backwards...
Danno,do you know if it better to run the ballance setting on the profec b at hard or soft?
When i have it set @ soft the wastegate opens in really fast little blitz.
When i have it set @ hard,the wastegate opens in bigger slower responding blitz.
What do you think?

You want to set it to get the best response to suit your tastes really. Set it towards the soft side to get quick boost and watch the boost-gauge for spikes. If so, turn it down a tad and that should do it. <img src="graemlins/beerchug.gif" border="0" alt="[cheers]" />

Thanks for the advice Danno <img src="graemlins/bigok.gif" border="0" alt="[thumbsup]" />
I really want to get the max out of this boost controller and its good to talk about are experience's to find out what work best ,so here's mine.
I just went for a profec b tuning drive and i tried all kind of ajustment and i still feel like the boost hits harder and faster when i have the ballance set at max.When i set it lower it feels like the wastegate opens faster in smaller burst to control I GUESS boost creep.(with a atmospheric wastegate it's really easy to tell when the wastegate is opening)
What setting are you guys out there running with Profec B?

I mounted my Profec B motor in the battery box. Wasn't too hard to install and seems to work good with my Tial 46mm wastegate. I have my max boost set at 15 lbs and my minimum boost is set at 13 lbs (mainly because I am running lean at 15 lbs in the upper rpm and have just ordered Danno's chips and injectors.) To get 15 lbs from the max boost setting I had to turn the dial to about the 1/3 level. To get 13 lbs from the min boost setting I almost had to turn the dial to 3/4. Is this normal? I figured the min boost and max boost dials were identical but it appears as though the calibration must be different.
On another note, I can now hear that nice loud ticking sound from the boost solenoid in the battery box. Is there anything one can do to muffle this sound? With the stereo on I don't hear it but with it off the ticking is quite loud.

That's funny,i have mine next to the batery and i can't hear it... even when i had my stock exhaust i could'nt hear it.

Yes,but mine are set even further then your's,maybe it's because i have a stock wastegate and you have a dual-port Tial.
Did you're new wastegate help in holding high rpm boost? That's if you still have the k26/6.

Edman: You can't hear your boost solenoid? Mine is mounted on the firewall beside the battery and it makes a really loud ticking sound when I get on boost. Anyone know why mine can be heard and his is quiet? I have a bursche cat bypass and stock exhaust and when I get on it all I hear is that loud ticking noise.
I have a k27/8 on my car and because I'm running out of fuel I haven't pushed the boost level higher than 15 lbs. I've been running at 13 lbs to keep things safe. My boost is rock steady and doesn't appear to be dropping at all. I've been told that the k27 will not hold 18 lbs though. I guess I will find out when I get my new injectors and chips.

Thanks for the figures! One question: How about 18psi with the SteveR? I'm wondering why you are running 18psi with the APE Stage II which apparently are set up for 15-16psi, but are only running 16.5psi with the SteveR that are calibrated for up to 18psi boost.

Well, with the APE stage 2 I didn't know I was running 18psi until I hooked up an aftermarket boost gauge...at which point I soon yanked the chips and the jet in the banjo bolt. But, I do know that people have tested the APE chips on the dyno and they are rich at 15psi...they have to throw in a fudge factor for those that like to crank up the boost way high...
After I dyno the car...and make sure my a/f curve is OK...I'll try an 18psi run with the Steve R stuff...as well as find out what fuel pressure I should use for 18psi and for 16.5psi...
Also...for all the 60-100 with APE chips I used one stop watch...all 60-100 with steve R stuff I used another one...I need to find the stop watch I used when i had the APE chips...maybe it's off...
Let me know what kind of numbers you get after you get your goodies installed, OK? My method: started at 50mph in 3rd, hit it...start stop watch when needle sweeps past 60mph...I shift to 4th cause I dont want to rev it too high and there isn't much point to it...stop at 100mph obviously...
I think with the APE chips I was shifting a little lower doing the 60-100's....so maybe I'll try shifting at 6k instead of 6300 now with the Steve R goodies...
