Power FC boost and Commander manual (searched)

[180crafter]

Hey guys. I dont often make a new thread, cuz u can usually find what u need by looking, but lo and behold, Nothing.

I have the power fc + commander + the boost controller add on.

Now I have downloaded the manual for the commander and the Power FC, but have yet to see anything for the boost controller add on.

Does anyone have any documentation on this??? Does anyone have experience with this??? How bout the tuning for this???

Thanks all.

[hurddawg]

you can call up Apexi, I'm sure they are more than happy to help you out.

180crafter,

Where did you download the English manual for the Power FC. I have a Blacktop SR and I just bought a Power FC but I don't have the English manual.

Thanks,

I got that all from the website. Its not vehicle specific, but it will do for a general purpose. It just doesnt have a thing regarding the optional boost controller thingy.

Im also gonna post on fresh alloy, try to see what I can find and report back here.

[180crafter]

Well, I havent posted on FA yet,but I have called Apexi and they advised to try and call a local place to see if I could get the paperwork needed.SOOOO....

I called XS, and spoke to some guy, very nice btw, tht actually got apex hq on the phone. They advised me that the paperwrk I wanted was nt available in English. Then the xs guy proceeded to advise me that the best course of action was to download the AVCR manual and guess my way thru...

Now this is my engine we are talking about, not a small child. I cannot just go guessing my way thru the things. I definitely do not wat to go messing things up (again).

I need the collective genius of you guys to assist me. I have yet to actually hook it up, that will come later this week when they put my head on. Until then, I need to learn how 2 work this crap.

[hurddawg]

**** I didn't think APexi was that useless. lol

if you can get the Japanese instructions I can help translate it for you.

[180crafter]

The japanese instructions are right on the apex website, but they are in Japanese. If you could email them to me, after babelfishing it, that would help. I cant open any translation websites from wrk.

[hurddawg]

hmm I didn't find the boost controller in Japanese on either the Japnese or US site. If you could tell me where its at (I looked at the documents section on the US site)

However the installation (except wiring) for the solenoid is the same as the AVC-R because the solenoids are the same. According the AVC-R instructions, it comes with a wiring harness that connects the pressure sensor and the solenoid to the AVC-R head unit. Both (solenoid and sensor) are shown in the JDM PowerFC manual, however they don't talk about wiring at all in that manual. If you don't hook up the PowerFC with the boost kit, the CEL will come on btw you can disable it using the Commander. So thats why I assume its the same with the PowerFC.

[180crafter]

Well the add on is on the portion of the japanese website that is under the power fc. I actually got one, but its only in japanese. Im goint to try on babel fish to maybe translate the instructions.

[hurddawg]

I can tell you that the JDM powerFC manual doesn't have what you are looking for as far as I can tell. Its mostly about how to use the PowerFC not hooking it up. There is a section called "optional parts" but it only talks about the boost kit (page 14) and what part number to get.

On the Apexi Japan website there is only 1 document to download for the S13 PowerFC.

P.S. on the US site under boost kit its says the boost solenoid is the same as the AVC-R

[180crafter]

Yeah I know that the solenoid and the hookup are the same, but what I am confused about is the actual tuning. The Power FC manual says nothing about how to tune with the optional boost kit and even what the screen looks like. The japanese website says all of this great stuff like "4 Presets" and yada yada, but I cant find 5hit else.

Well, I officially havent seen my car for one day....

[hurddawg]

got it. Pages 54-57 describe that. it looks fairly simple to operate.

Starting on page 54 from the big number 1

1. On the main menu select "setting". (#1 in the pic is saying using the arrows to select, #2 to continue)

2. In the "Settings" menu select "boost" (the pic is the same but the unumbered one says "go back", "return", etc

Page 553. This is the boost setting screen. Select the number you want. (The pic on the left from left to right..."Setting number"...."Set boost pressure"...."Base duty"...."fuzzy logic value??" The pic on the right is mostly the same, but the right button is used to change boost pressure or base duty.) P.S. these are the 4 staged boost pressures btw

Once you moved over either pressure or duty, use the up or down arrows to adjust the value. Use the left/right arrows to move between the values and presets. The last box is just telling you how to return to adjust the other presets

page 56

On setting the boost pressure...The 4 presets can be adjusted between 0.5bar to 2.0bar. You can set the boost pressure above the actuator but not below its setting.

On solenoid valve duty control...With the Power-FC controlling the boost pressure, the duty control used by the solenoid valve, at the set boost pressue, is how boost is controlled. (essentially saying the boost is controlled by the duty valve you set)This duty control, turns the solenoid valve on/off rapidly and variates the percentage and length of time the solenoid is in the "On" position and that is how it controls the boost. Duty at 100% and the solenoid is always on, at 0% the solenoid is always closed.

On the relationship between boost pressure and Duty...Normally, the pressure is controlled by the actuator. <Cut out a bunch of crap> When the solenoid is off it allows boost pressure to reach the actuator. vice versa for the "on" position. Higher the duty, higher the boost pressure and vice versa.the duty value must be adjusted so that it is near the boost pressure. Once the duty value is close enough to the boost pressure, the power-fc will automatically adjust the value. But if the pressure doesn't reach the set boost pressure you must adjust the duty value.

page 57If boost pressure doesn't attain/passes set boost prsssure...

-If the boost pressure doesn't reach the set pressure a) the duty value is too low. In this situation, adjust the duty value higher, a little at a time.-If the boost pressure is much higher than the set pressure a)The duty is too high, in this situation lower the duty.

too small a turbo, or unobtainable boost pressure maybe another reason why the set pressure is not reached.

Fuel cut when boost passes its setting- If the set boost pressure is exceeded by 0.25bar the PowerFC will cut fuel.

To control the boost pressure other than the power-fc...from main menu goto "etc", -->"Function Select" and set Boost Cntl kit to "no" As long as this option is selected, the Power-Fc will control the boost. However even if you don't use the boost control kit, The powerfc will cut fuel if the set pressure exceeds 0.25bar from the set value.

good luck man

[180crafter]

GOD DAMMMMMMMM!!!!!

You are the most helpful MOFO!!!!

Dude, I love you. I love you like a man loves football, and as much as I love my mom. But not as much as I love my car. Never.

[hurddawg]

glad I could help out

[USsil80]

180crafter.. did that kit come with a pressure sensor... i have a power fc with a avcr i just want to know if i could get the pressure sensor hook up

[180crafter]

not too sure to tell you the truth. Its all in japanese....

I figured that the Power FC reads the pressure straight from the controller itself, like tht little black box tht goes in the engine compartment.

If this isnt the case let me know...

[hurddawg]

it does have the sensor

[USsil80]

soo you have to get a special preasure sensore then....

[180crafter]

Yeah.... The little solenoid, so I guess that is the sensor.

[AX75F92]

Both the boost control kit and the AVCR come with all the sensors you need (pressure sensor and a solenoid valve).

[USsil80]

yes i know but how do you get one sensor to work for both

[AX75F92]

Quote »yes i know but how do you get one sensor to work for both[/quote]

To work for both the AVCR and the Power FC boost control kit? Why would you want/need to run both?

I dont see where youre coming from.

Is your Power FD D-Jetro?

[180crafter]

Good point...

The fc has its own boost controller capabilities, you dont need to run a seperate boost controller like the AVCR.

Saying that, I have heard that there is alittle more boost control when using a separate controller, and I have heard otherwise.

Still miss my car BTW. Went and bought the gt28rs, some injectors and am in the race to fix up the head.

[AX75F92]

Yeah. Boost control is a little more aggressive when using the AVCR in conjunction with the Power FC. Either way, You dont run both the AVCR and Power FC boost control kit. You wouldnt need to run sensors for both, like you said above. Its either AVCR, or PFC boost control kit.

[USsil80]

my power fc has pressure boxs so you can tune using pressure and rpm

[180crafter]

help me!!! I need help installing the Power Fc boost kit. I dont know where to put the 2 prong wire that comes out of the solenoid. Let me know.

[ericherm1]

I have the exact same problem. I have the Power-FC with optional boost control kit and I'm confused as well on where to hook up the 2P connector off the solenoid??

Apexi says that its the same as the AVC-R but that has a pre-terminated wire to connect to the solenoid and the Power-FC does not.

Please help the wire colors are " 1 Red wire, 1 Brown wire"

ThanksEric

[ericherm1]

Here is the only page that has anything about the wiring of the solenoid. Can you please translate this for us.Thanks

[ericherm1]

OK for all you doing the optional boost control for the Power FC you must hook it up to the stock boost solnoid wires. On the S13 redtop and blacktop you will have to cut the wires and splice them. Don't worry they are labled pos and neg so you can't go wrong. S14 will plug right in... well on a s14 stock boost solnoid.
