would be correct in assuming that in these bloody things there is supposed to a high tencile spring anda little ball???

Cause i just pulled it apart for the first time after trying everything to get it to work and there is no flaming ball in the end of it!!!!

WTF!!!!

Yeah there's supposed to be little ball in there. Get onto mark and get him to rectify it or send you a ball or something.

The little ball rectified it. Works like everyone on her has said it would.

All is well. Onlyset to 9 at the moment. Will have a play with plugging the hole up versus having the hole and get her to about 11,12 ish and see how she goes.

Cool man. Did you get the ball off the guy you sold it off?

The whole in the boost controller, is to allow air to escape when you close the throttle.

This then allows the wastegate to close again.

Also, if your boost is dropping 5PSi, it isn't the hole doing that. That's ALOT of pressure to loose through a tiny hole.

By a 5psi drop, the spring and ball should have closed, all air should vent out, allowing the wastegate to close, and boost to climb again.

It sounds more like your turbo can't keep up.

ok fellas.

ive used 4 of marks controllers.. 2 holes and 2 non holes.. on a GTR S14 and GTT with NO dramas what so ever..

untill this morning when i put one on my 180sx.. only occassionally it spikes..

boost is set to 6psi.. first gear is normally stead might spike to 10psi.. 2nd gear normally spikes to 10+ and 3rd gear ive seen it spike to 15psi..

on the hhighway build boost in 5th it wont spike. it will mostly only spike after changing gears..

this has really got me..

i purchased this controller a few months back with my first shipment from mark and its been sitting on the table outside for 3 or so months so i might check the insides of it tomorrow.. had very limited issues with the standard solenoid.. it would go to 10.5 and fall to 9ish.. but seeing a 15pound spike is quite scary.. esspecially when the can is on closed loop mode lol...

so ill post up what i find..

ok, ive put it on my s13 now, and ive got it so it sits at 9/10psi, but when i first gun it, it hits like 13 psi and falls back and sits at desired boost level, but when it goes to round 13, it coughs and splatters.... is this boost cut or missfire or??? it blows a lil bit of smoke when it splatters, and its only for a second untill the boost goes down a bit, and why is it going up to 13 then coming down so much?

Which direction do you turn the dial to turn boost down? Clockwise/Anti-clockwise?

Boost is spiking so I want to turn down, but I can't find the original instructions that came with it.

Screw it in and get more boost.

Wind it out and get less

Hi guys,

Today I was fiddling with my controller and dropped the spring into my bloody engine bay and could not for the LIFE of me find where the FK it has gone.

Anyway provided I don't find it, does bunnings sells the same sort of spring? Anyone had issues with replacing the spring?

I need the controller working by tomorrow as Im taking my car in to get a SAFC installed and tuned and want it tuned for 12psi

Somewhere in the 1500 posts on here someone has mentioned something about a replacement spring - i remember reading it ages ago but i cant for the life of me remember roughly where.

    • Even with the piston at TDC there was room for it to drop, but I don't think it can drop fully into the cylinder, the problem you have is that you need something pushing against the valve to hold it up so you have enough room to put the new stem seal on and the spring etc.  I used compressed air only because putting rope in the cylinder seemed a bit risky to me, I know people have done it countless times before like this. Overall it's a pain in the ass job. Honestly you'd probably be better off taking the head off because the risk of dropping something in the engine and the finicky-ness of it all is very stressful. If you are going to attempt it though i 10000% recommend a 36050 valve spring/keeper tool. I had both the traditional lever type and after doing 1 cylinder it was absolute pain to get those valve keepers in place, even with 2 people. That 36050 is amazing, you do have to push hard to get them in place but it works perfectly almost every time. Back to my actual issue I think my engine is just tired and old and the rings have gone bad. The comp numbers (cold, no oil) were: Cyl 1 -129psi Cyl 2 - 133psi Cyl 3 - 138psi Cyl 4 - 137psi Cyl 5 - 157psi Cyl 6 - 142psi   Cylinder 5 and 6 having the most carbon on them.
    • Who did you have do the installation? I actually know someone who is VERY familiar with the AVS gear. The main point of contact though would be your installer.   Where are you based in NZ?
    • Look, realistically, those are some fairly chunky connectors and wires so it is a reasonably fair bet that that loom was involved in the redirection of the fuel pump and/or ECU/ignition power for the immobiliser. It's also fair to be that the new immobiliser is essentially the same thing as the old one, and so it probably needs the same stuff done to make it do what it has to do. Given that you are talking about a car that no-one else here is familiar with (I mean your exact car) and an alarm that I've never heard of before and so probably not many others are familiar with, and that some wire monkey has been messing with it out of our sight, it seems reasonable that the wire monkey should be fixing this.
    • Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.
    • Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it.
