HOWTO: RB25DET High Boost mode with standard solenoid

[justin911]

which wire in the ecu do u planning on hooking it up ?

i made a little switch for someone ages ago.. it had a led on it that used to flash when it was on etc.... there was 3 pins..

1 went to the power source, 1 to the ground and other one to the power source (white wire i believe) on the solenoid (not the ground wire like normal.. but we did permanantly ground the ground wire..)

if that helps at all

Well I just did mine last night and it works a treat. I actually got the switch upside down but I don't care. Mounted the switch on the dash behind the wiper wand and put the ground wire on the transmission bolt rather than in the engine bay. Shaweet!!!!!!

[justin911]

did u end up hooking it up to a wire on the ecu ??

not trying to be a smart ass im just curious as to which wire it goes to on the ecu ??

Yes. I did it as per my previous post

[justin911]

ya but which wire on the ecu did u hook it upto ???

All I did was snip the black wire which runs from the ECU to the actuator. I didn't touch the white (power) wire, and put a switch to connect the black wire back up. I didn't touch the power wire as I didn't use an illuminated switch.

My setup is abit different from everyone else's. Is it still ok to do this mod since the 2nd solenoid nipple is being used?

And if so, which wire goes to ground, white or black?

<{POST_SNAPBACK}>

Your setup is the way it should be Wink, the way it was when your car left the factory. All the pictures on this thread except this one are horrible mutations (like mine ).

hey sorry if this is a bit off topic but does anyone know where the return air tubing on the solenoid goes to? i know it goes back to the intake somewhere but i cant find the exact spot. my solenoid has been removed and i wanna check if the hole has been plugged up properly.

Pics would be muchly appreciated.

Thanks!

this could be the most stupid question on this thread, but -

if i were to pick up one of these boost controllers and a guage, could i replace the standard solenoid with it? im an ex XF falcon man - this sh*t is space age to me, and i respect those of you who understand it and pass on your knowledge and tricks!

if it is possible to substitute the solenoid with a boost controller, what happens with the pos and neg wires from the ecu?

[toffy]

has anybody done this mod and taken that little restrictor out thats in the top hose? . cheers

Sorry about the late reply.

Yes, you substitute the solenoid with the boost controller...as the solenoid essentially does the same thing just that instead of allowing more boost it actually limits your boost.

You need to install the bleeder on the pipe going between your intake pipe (after turbo) and your wastegate actuator:

Its the pipe with the white joiner bit in the middle. By looking at your boost controller I would assume you would first plug the line into the nipple marked with the arrow, then plug the other end into the remaining nipple but if that doesnt work, try the other way around. Shouldnt matter anyway.

Hope it helps

Sorry is this mod reverseable?

[rinmak]

If its done in a method that allows reversal then yeah.

Basically just need to hook the wires back up they were originally instead of grounding one.

hey guys, my mate done the trick for me, but its not working right?, i think hes installed it incorrectly........

heres a picture showing what he has done, the white wire is grounded, is that correct???

[nsta]

hey guys, i just got myself a turbotech boost tap, can you help me install it, this pic, which is someone elses is clear enough to show me which hoses connects up etc....basically can you use microsoft-paint or sumthin to show me which end of my boost tap goes to which part on the intake/solenoid....hope thats easy to understand, even just labelling which hose is will help out, (ie wastgate actuator hose)

i'm really new to all this but would like to do this myself

thanks

p.s do i need to return this high boost mod to factory before installing the boost tap?as i heard this mod limits the boost from going over factory levels?

can any tell me which pin the black wire goes to on the ecu? Just so that i can do the whole mod from inside the car?

& why can't i just connect the 2 pipes up that go to the solenoid to get the same effect?

[NICKS33]

guys just cut the BLACK wire and connect it to the bolt that holds the braket on.....easy....dont try to make it harder than it is...

just watch out when u hit boost mid corner

[nsta]

hahah, wish you made it sound dat easy earlier on, my mate grounded the white wire!!!, could he have screwed up the unit???, ive since put it back to normal....and is this trick worth while doing if you have a boost tap?

[Techo]

i got no worries with 4WD!!!

[STAGE-A]

Q..and is this trick worth while doing if you have a boost tap?

A>.if you already have a mbc, this wont do anthing for you as you have already replaced the boost solenoid with the mbc
