I have been trying to find info on this product and see if anyone has used it. I would like to know if it is worth getting over a stand alone boost controller. also it looks to me that the only thing in this kit is the solenoid and map sensor, so why is it soo expensive if you buy those parts separately it would be cheaper wouldn't it? Here is link to ebay sale for said item.

Also here is link for same product but for nissan. (just it shows all that is in the kit)

Has anyone used this or know anyone who has? This product is new to me I didn't even know it existed until coming upon a site selling the solenoid and mentioning it ,since it is the same solenoid used with the AVC-R.
With what I have been reading couldn't I just buy the solenoid and a 3 bar map sensor and plug the solenoid into the turbo control solenoid spot on the stock wiring harness. (The solenoids on front of UIM, was told it plugs into one without white dot)
Just wondering, cuz Im all about saving money but not at the expense of safety or performance.
Also I am running non-seq with a street-ported motor so anyother considerations i need to be aware of when it comes to PFC tuning?

 

Yes, the solinoid is the same as the AVC-R so you can just use that. The map sensor then needs to plug into the side of the ECU and I think that is a 3 wire plug. Its nice to incorporate it into the PFC because now you can log that data with everything else. Its really easy to change your boost setting too. Just select from 1 of your 4 settings and you are good to go. You do have to enable the boost kit inside the PFC if you do add it though so don't forget that.

 

the AVC R solenoid directly plugs in to replace your factory solenoids. the way to hookup the AVCR solenoids is the same as how you would with AVC-R install. Technically you switch out your factory map sensor with the 3 bar and plug the original map sensor into the side of the PFC. it double checks the map reading with both sensors.

everything's direct plug and play

 

i always thought the boost kit was for other car models, i didnt know it was compatible with the rx7. I have a profec e-01 and it came with a solenoid just like that and some kind of map sensor, could i use this for my single turbo setup? will it have similar benefits at an avcr or profec electronic boost controller.

 

ok after reading more about the boost kit it sounds like you dont need the extra map sensor if you dont plan on exceeding 17 psi. Though apparently the pfc uses the 2 map sensors as a reference to better control the boost. The gains are apparently minimal. I'm still wondering a couple things.. if i can use my greddy solenoid with the PFC? and if it will keep my external wastegate closed longer similar to other electronic boost controllers?

 

So does anyone have a pic or diagram of how it to be set up? Cuz I have found the solenoid for like 150 versus the 400+ dollar kit. Also a 3 bar boost sensor only costs like 75 bucks. Also once you plug the new solenoid in does it change the interface in which you input boost levels? How does it work?

 

greddy solenoid, you'll have to install the full greddy boost controller. It'll bypass the stock solenoids. On the other hand, if you use a Apexi solenoid, it plugs right into stock solenoid plugs (i'm not sure about the AVCR solenoids, but at least the one that comes with the boost kit does. should be the same)

after you hook it up, in the commander, you'll adjust boost only with the first and primary setting only as if its a single, but the sequential will react the same

 

does it keep the gate closed longer like the avcr and such?

it seems like the only difference in the solenoid is the plastic connectors, i believe they are just 2 wires that make a connection to open or close the solenoid. I'm sure i could get the wires connected one way or another. i dont even think it matters which wire goes where.

 

I have Power FC in 2nd gen and my Profec head unit took a dump and will not open the wastegate.

I also have a AVC-R boost solenoid. I would like to know how i can connect it to run from the Power FC. That way I can just get rid of the Profec and use the commander/datalogit to control my boost.

 

Yeah u can use the apexi solenoid to control boost. Here this might help answer your questions further. This great link was given to me by Godzira.

I found it to be useful. Still trying to find out if you can buy the wires seprately. Also if the boost sensor included with the AVC-R is the same (Like the solenoids are the same.) If so I found a place to buy the solenoid and sensor for cheap thus eliminating the need to overpay for the kit.

Do our PFC's have a 5 pin plug for the second kit? The reason I am asking is because I have a series 4 car which doesn't have a stock boost control solenoid, and thus no place to plug in the solenoid for the first kit. I really would rather not pull apart the carpet to get to the ECU right now (it's harder to get to on an FC than an FD)...

 

i also finding a set power fc for my FD3S

but i am very afraid getting something fro ebay..

since its not cheap, i am afraid my hard ear cash will got rip off>

anyone brough from them before?

 

I think it depends which version PFC you have the older ones came with 5 pin connectors on the side and the newer ones came with 3 pin connectors on the side. This is how i understand it anyways.

 

actually im not sure, it might be different car models, i'll pull my PFC out and count them. EDIT: mine has 5 wires. So 3 are for the map sensor and 2 are for the solenoid. once we have a pinout we will probably have more options.

I have a feeling other solenoids will work too. They might not be plug and play but with a little adaptivity can probably be used. I think the boost control kit can be utilized for much less cost.

Here is some helpful information taken from the link posted above:
"The pressure sensor has the main wiring harness directly attached to itself, one end plugs into the 5 pin port on the PowerFC. The solenoid piggybacks off the Pressure Sensor wiring harness which leads to the PowerFC connector port. The wiring is shown below.

MAP Sensor
Red = Positive
Black = Negative (earth)
Green = Signal

Solenoid
Pink = Positive
Black = Negative

When the solenoid wiring meets with the Map Sensor harness the colours for the Soneoid change as follows;

Pink = Red
Black = Brown"

 

Yeah it seems as if I could make this work without buying the kit. I am using the Apexi map sensor as my primary sensor right now, so I could take a stock FD map sensor and use it for the PFC and then wire in the Apexi sensor into the boost connector and to the solenoid. hmmm

 

Just made a discovery that is relevant! The boost sensor that comes with the AVC-R is not the same as the one that comes with the boost control kit. Also has anyone found the boost sensor and harness for sale separately? I have heard of people buying the kit in pieces cuz its cheaper.

 

i have a spare avcr soleniod and boost sensor can anyone confirm wether the avcr boost sensor works as aposed to the boost kit sensor. i do not have the plug for the side of the ECU. does anyone know the pinouts? so i can use another plug.

my ecu has 5 pins.

 

Here is a pic of the boost control kit for the 240sx/sylvia, part # 415-A001 .

I wonder if this is different than the one designed for our cars, and whether it is compatible. I would think the only differences would be included harness.



Here is a pic of the replacement MAP sensor for the AVC-R, part # 499-X002



So if you compare the two pics, they do look different.

More searching of sites like http://xatracing.com/Store/Product/I...Make=UNIVERSAL

indicates that the boost control kit MAP sensor might be part # 499-X001 , the same sensor used for a D-jetro (speed density) conversion on a skyline.

Then it lists the 3 pin pressure sensor harness as part # 49C-A002 and the 5 pin pressure sensor harness as 49C-A004 . The models it lists for the 3 pin pressure sensor harness are D-Jetro Skyline PFC's. But that doesn't necessarily mean that the 3 pin harness is only used for those models. I have never seen the FD boost control kit in person so I am only going off what I read.

It's still not clear how interchangeable all the parts are and what the cheapest DIY route is. I do have a friend with a 2nd gen who has an AP Engineering PFC, and he just plugged the solenoid into his factory boost control harness plug. He doesn't run the pressure sensor at all (he is using an FD MAP sensor)--but I cannot say how stable the boost control is as the car is basically untuned.

 

I have the solenoid and it definitely plugs into the FD harness. I also have the map sensor, which I picked up separately. This will also plug into the FD harness. I have not installed either on the car yet.

I've never understood if this means I now have an full boost control kit or also need a separate harness to go into the PFC. Where would the harness go to?

 

Should have spent more time reading this thread! The harness would go the boost sensor. But would it also go to the solenoid (since there are a total of five wires in the harness) or does the solenoid plug into the factory harness (as suggested above)?

 

plug that stuff into the factory harness and see what happens. i think you need to set the MAP sensor to option 2 and then you can adjust the boost with the commander or datalogit

 

I've ordered the harness (PN #49C-A004) so it will be interesting to see if it connects directly to the solenoid. Unfortunately, I will not be able to experiment with this for several weeks as my car is apart at the moment while I install a computer system.

 

I await your results. My PFC is on a series 4 2nd gen which does not have a harness plug for a boost control solenoid. I am thinking about running that harness with the boost control solenoid. The main reason is because I don't want another damn clumsy box in interior with all the associated wiring and plumbing. If it doesn't work, oh well.
