Yes, the place is perfect for the controler, you will never see it's there if you don't know. And I think that it shouldn't be to some easy and well to see place, because after all you will set it once or twice,and after that it is just staying there and doing his work.

One more pic of the final look

Hi chaps, installing mine now, can someone tell me if you need to use the vacuum source if you already have a boost gauge installed? Or is this required to monitor the boost? Also the electrical connection on the replaced controller does this become defunct?

Thanks

No mate, but you need to tap into the hose that runs to your boost gauge, somewhere in the cabin

and connect it to the back of the hdi boost controler .

Top man, also I fitted the new solenoid connector through the groomed by the wing (pass side) but it does not seem like it would fit across to underneath drivers air vent? Can ask how you did it please. And if same as me how did you route it once inside the cabin?

i ran mine the same way you have and it only just reached to where i placed the boost controler , i ran the wire under the dashboard ( where your feet are ) with cable ties and it was very tight on cable only about 10mm of play left .

Haha sound, Mine too! Last questions (at least until the next one) but with regards to the solenoid itself, how did you mount this also what did you blank of the unused pipe from the old controller? Again thanks for your help plus the rocker works and looks a treat!

i used a bit of boost pipe and just joined the two ports that i disconnected from the old ebv and i mounted the new ebv on the same mounting that the old ebv is on and i'm glad your happy with your rocker cover

Hi I need a little further assistance, I have it plumbed in and wired up. However the control is box is lit up with sel bit will not let me choose a hi or lo setting and also my injector light is on yet no faults showing on my widget. Please help!

Mick

Hope you have left old EBV Electrically connected?

I haven't mate, is that the issue with the injector light? What about the controller not letting me select high or lo to adjust?

Injector light sorted, just the controller now! Just taken for a spin and only getting half a bar boost!

You're probably on base boost. Have you wired it up correctly, with one permanent live straight from the battery and one from ignition?

Hi pinin, yes I took a direct feed for the battery+ I also took a direct feed from the battery for the ground to see if that was the issue. The switched live i took from the boost gauge - this may be the problem? Have you taken yours straight from the ignition? If so which is it? Also I used scotch locks but the gent from hdi said I need to solder, have you soldered yours?

Thanks

Mick

I took switched from windows switch!
Also didnt solder mine,just joined them and insulated with some tape!

I didn't wire mine up Mickey, Taffy20VT did. I think he used the window switch though. You may have a duff one if it's definately wired up right. Sorry!

Thanks Al Galone and no worries Pinin, Not your fault, I think its been a great GB - just need mine sorting. The chap also mentioned using a Multimeter to check the plug, I am assuming he meant harness connection. I have a multimeter, but i do not know how to use them, Can anyone advise me on which setting to choose, And which colour test wire you prod it with (red or black) and if you have to touch the remaining probe to ground? Also finally (sorry chaps) but what values should i be expecting?

Sorry for the request for information, but would rather try everthing before posting back!

Many Thanks

Again

All sorted, got a grasp of the multimeter and located it to a connection just before the harness! Blasted scotch locks!

I very much agree with dlongstaff that it feels spot on, again not sure if it is just in my head but the car feels so much more responsive and powerfull!

Big shout out goes to pinin-prestatyn for setting up the group buy oh and for giving me a this emotion on my lastest drive

Whoop whoop! Happy to help

well done Mickey - gotta wait for installing mine (legal issues) - and time needed to research options etc.

I am planning to fit my unit this weekend. It will go under the dimmer switch.

Can someone advise:

Do I need to obtain additional tubing and wiring?

Is it possible to route the wires through the bulkhead, and if so whereabouts?

Thanks

Hi

No you do not need any extra tubing or wires, It fits nicely under the dimmer switch. It is tight however. (This is were mine and a few others are)

You also can put it through the bulkhead, and a lot easier than i thought. There is a how to but not sure where and how to paste it (hopefully someone else will) But the option i chose was to take the passenger wing off (very easy) and is uncovers a grommet you can feed the power leads down and then feed it from under the glove box to the drivers side of the car.

In terms of piping have you a boost gauge fitted already? If so you just need to plumb it into the original tubing with the t-piece supplied (no need to pipe another tube into the car from the outside).

Hope this helps.

I completed the install on my unit last night. It appears to do everything I expected.

On its lowest setting max boost is 0.4 bar
On its highest setting max boost is 1.3 bar
Can anyone else confirm a similar result?

When I removed my boost pipe last week I did a quick max boost test and it reached 1.5 bar, this implies that the unit is either limiting max boost or is not capable of allowing max boost?

Unlike others, I found the install hard work. It took me 3 evenings to complete. The Battery wire was way too short, and I had to cut into the Unit wires for the switched live.

After spending hours contorting my frame in the footwell I'm aching - need a well earned beer and rest

THe performance of the car has increased significantly, I have had a faulty EBV which has only allowed a max boost of 0.7 bar. Over the last 8 months I have gotton used to this level. 1.3 bar is quite a noticable improvement.

On wednesday, It goes to Leighton to fine tune and squeeze some more performance and safety out of the car.

Big thanks to Matt - I am very pleased with the unit.

On my lowest setting, I get max 1 bar and it sticks there.

As I turn the knob clockwise, the boost does increase. It went over 1.2 bar. I know this as the warning feature on my boost gauge beeps as it touches that preset amount.

Weird thing is 1 bar at lowest setting. I'm certain that the solenoid is doing it's job because when I was on the EBV, I had boost spikes up to 1.5 bar! What could be wrong?

I have had a setback. the two wires from the back of the unit to the actuator have melted together

Tonight i will pull the unit apart, and attempt to re-wire it.

I will also check for shorts along the wire running from the actuator running back into the car.

Suggestions on a postcard please.

Unless i have success this evening, I will have to cancel my Re-map planned for tomorrow.

Mapping Cancelled

I have been doing some testing tonight. The live, switched live and earth are all OK. The unit lights up correctly and makes all the right noises.
If I connect the 2 actuator wires to the unit the lights dim and I have a short.
I think I have either a short on the actuator wires or a faulty unit.
What voltage should I be seeing to the actuator between low boost and high boost settings?

I will be removing all of this from the car tomorrow and doing some bench testing, any suggestions would be welcome

As suspected, the short was along the actuator wire where it meets the gromit. The positive had "pinched" where I missed the gromit.

I am now asking HDI if they can sell me just a boost unit without a solenoid.

Today i have bought an inline fuse ready for the new install. I'll do it properly this time.

If anyone has a boost controller for sale drop me a pm.

Matt if you respond to my PM I may need your contact details - the one I wrote to has not responded.

Driving around on 0.4 bar max is quite boring - At least I know what it must be like for the NA owners now though

I purchased a new boost controller this week and have just fitted it - with an inline fuse this time

I have a question though. Base boost with the controller turned to min is 0.4 bar, max boost setting spikes for a second on 1.2 bar and drops to 1.1 bar. At high RPM the pressure tails off to around 0.9 bar.

Can someone explain why these controllers limit boost to 1.1/1.2 bar?

If I disconnect the bleed pipe from the EBV I can achieve 1.5 bar which is what I would expect, why does a unit rated at upto 4 bar do this?

It is unlikely that the controller is the problem Tony. If the wastegate is too weak, which 0.4bar is, then you would struggle to achieve higher boost even with 100% duty from the solenoid. The wastegate arm can be adjusted in situ, so shorten it by about 3mm to increase the pre-load.

Thanks Leighton.

I've adjusted it (pig of a job!) and now achieve 0.6 min 1.3 max. I will give it a final small tweak to 0.7 and 1.4 bar and then I'll pay you a visit
