Got a link to the condensation filter thingo?

in line vacuum apexi filter
Ebay link;
(3) 4mm Boost Controller In Line Vacuum Air Filter EVC Profec A B APEXi 15900011
(Best to just type in "inline apexi filter" into the ebay search tab)
Google;

From what we understand mate they stop the condensation and other crap getting in and they get changed at least every 12 months.
A (different brand filter) product summery from ebay says;

Inline Filter for electronic boost controllers or boost gauges etc. Stops debris from entering boost sensors or from blocking small bore gauge connections.
These filters also help offer protection from pressure spikes that could potentially damage sensor diagphrams or mechanical gauge mechanisms.

Sorry for the tripple post.
Have a new phone and i was just trying to edit the post to include your picture, as my previous phone would do when i quoted soneone.
After the 3rd attempt, i gave up.

All good Speed, new phone, all forgiven for at least 1 week

For others like me, thought I'd post the cut to the chase comments in the aforementioned SAU thread.......

I always thought it was to catch any moisture/ vapour in the lines to avoid damaging any of the electrical/mechanical parts inside the boost controller. When you compare this to an Air compressor, Painters usually have a moisture catch in the lines so they dont get any water sprayed out with the paint. as Air compressors usually catch a lot of moisture. Thats how i look at it.

yes they are there to protect the solenoid, the map sensor or any gauge sensor. they are a good idea. I wouldn't say they are essential but if you can get some and fit them then by all means do it. they ensure only clean air gets to your device. just watch they don't get blocked or split/leak. it does happen.

After installing my HKS evc that has the filters, i woudl say they are definitely nessasary as over a period of 7months they have accumulated a small amount of oil which can possibly throw off accurate boost readings inhibiting proper/optimal boost control.

I would really like to find out where they are sold and replace them every year or so.

the child was "safely" re tuned richer and de-boosted a few psi for piece of mind for the impending Sydney trip next week. So I have a temporarily milder problem child to show off next week

Really looking forward to meeting you and seeing the car.
I wouldn't worry too much about the performance drop as you'll probably get stuck behind a slow car like mine.

Besides, its more about the drive than the speed anyways

Cheers Steve. Still just a little disappointing I dont have time to get her running best before I head down, I guess its just a human nature mindset to want to show things in their best light in circumstances that you dont get to enjoy every day. I'll be driving down on Tuesday- thinking about calling into Haltech while I'm down. We spoke with them when trying to figure out a workaround to solve the issue (for a long term result) without having to sent the unit back to them to pull it apart and sort out the internal sensor (trying to save some $$$ if I can ).

Got the new MAP sensor and filters delivered- the dyno is booked in, but I'll have to wait 4 weeks before any work can get done! I was planning to cruise back to Sydney, but may take a couple of months now damnit . Tuner is booked flat out dealing with all sorts right now (a few pics of one of his regulars- boosted 3.5 VQ35HR V6 powered...... you'd need a good chiropractor to drive this long term!!)

[Daffy]

New bits arrived, ready to install.

[Daffy]

Got back on the dyno today to get her running right after the Sydney trip and weeks of A to B driving on a de booted sedated valet tune with a dodgy condensation affected internal MAP sensor in the Haltech elite- things we discovered......

The condensation Filters previously thought of are no good on boost better than 10psi- fell to bits pretty quick too and stuffed the dyno data...... (check the before and after pics!)
Seems for future better to just consider the newly installed external map sensor as expendable and just keep an eye on psi readings and air fuel numbers, then replace the sensor as required once contaminated after too much E85 condensation buildup.......
We had to play with voltage through the fuel pump- dropping pressure under load (wtf???)......
no clear indication with flow rates. Now this is where I could have actually had positive feedback into the diagnosis of what was fritzing out rather than looking like a complete hatstand, nufty, bill paying passenger, when better mechanical minds than mine were trying to sort out impending issues! I thought "I should suggest that we hit the softer "targets" 1st before pulling out the entire fuel assembly to see if there was a blockage or fault........., 1st thought I had was being a dodgy fuel pressure regulator- which was a brand new AEM that we assumed would have nil issues being a new unit (missed a golden opportunity to actually look mechanically smart for a change ). After pulling apart and testing the fuel pump assembly, filters, etc from tank to rail, we finally (via dyno readings assist and swapping the FPR readings through a new TOMEI FPR that was on hand).......... yep...... the AEM FPR appears f**ked- If I spoke up when I thought of it, we could have saved a lot of time.

On the upside, the Haltech firmware is now updated and with the new TOMEI regulator and some fresh spark plugs to go in before the re tune, the Problem Child should be back her ball tearing ballistic normal after weeks of sedated puttering by this weekend.

Make sure the TOMEI FPR is legit not a copy...

Thanks mate, much appreciated! When I drop her off today I'll give it a good look over referencing the linked info with Matt. The one we used in testing yesterday was one that he had on hand that was still new he bought for himself- so fingers crossed his industry supply contacts he buys from do their homework!

S**ts me when you think that there are so many shonky on sellers in Australia that have no issue ripping people off (especially thinking of the seriousness of what can happen when these dodgy parts fail )
