Hi all

I'm doing a boost controller and fmic instal link http://www.sau.com.au/forums/topic/454062-car-making-0-boost-after-ebc-and-fmic-install/

It wasn't working and I decided to take off the fmic and put the smic back on

I did this then started my car. The stock boost sensor was working now and it climbed slightly. I revved my car and the greddy ebc got to around -99. I stopped revving it and switched my car off and the turbo timer kicked in. While this happened it sounded like the car died then started back up then died and started back up. It was like a sort of stop stutter thing. I ran to pull the negative terminal out the battery to make it stop. There was slight grey smoke coming out of the engine at this point too.

Car was going fine before I removed the fmic I just put in and installed the smic.also I didn't tighten any hoses which connect the afm or smic as I was going to take it off again shortly.

Can someone please help. I'll try find a mechanic that can help but please can someone give some help

I wouldn't stress over it, id put the fmic on and tighten all pipes properly, then just set up wastegate as stock until you can figure out or find some to install it properly..

it would be stalling because the pipes were loose, so a vacuum leak

Replace the short, un-teed piece of hose to your fuel pressure reg, the way it was before you did the EBC install and never touch that line again.

Put the original hoses for boost control back. Make sure all your IC pipe clamps are tight.

See what it does then.

Oh, and f**k that turbo timer off. You don't need it. No-one has ever needed one. Just do the turbo cool down manually. And they are illegal anyway.

Okay cheers guys. I did freak the f**k out a bit aha. If I re connect the fuel pressure regulator the way it was then how would I wire in the boost controller ? Also I know about the turbo timer but when I purchased my car it had one and I have no clue where it is ? Started to think gtt's came stock with a built in one because I have no clue where it is and I was told the car was completely stock upon purchase (which besides a pioneer head unit it was)

As above Put the FMIC back in and make sure all the hoses are tight and remove the T from the fpr line. As for a boost source - the line you blocked off on the bov return pipe was for the bleed line - you must have had another line to supply boost to the original boost solenoid (normally from the pipe going to the intercooler).

The factory boost sensor is connected to the back end of the plenum. That's the BEST place to get a signal for other gauges or EBC on a Skyline. The EBC install manuals only tell you to use the FPR signal line because that one is available on pretty much every car. Even if it isn't the smartest option.

It shouldn't be that hard to connect a EBC, it needs a source of pressure, it needs to be connected to the wastegate, then it needs to be able to bleed that pressure off, simple as that..

on my apexi, one end of the solenoid has the tube connected to the FPR, other end to the wastegate, simple as that, the solenoid has its one hole to bleed pressure off and control boost, the electrics plug in to controller and that's it..

I'm located in Perth and I think I solved the problem with the car stuttering but there's still no boost. My cars drivable now so I think I'll just drive it to a workshop to fix it up then tune my ebc on their dino and get a tune while I'm there. Thanks for the help guys !

Do you have an alarm/immobilizer installed? Some of them have a built in turbo timer, so find your model / manual and have fun trying to reprogram it, usually a sequence of turning the key on/off a million times at exact intervals.. haha... good fun...

Well I bought it from a dealer so legally there needs to be an immobilizer but I have no clue on what one it is. I'll have a look at it later and try see if I can disable it because it's annoying

      After market rear camber arm adjustment

      By Duncan · Posted

      Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber

      I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option

      You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)

      I got adjustable after market rear camber arm to replace the stock one's because got sick of having to buy new rear tyres every few months. Can anyone please let me know what the best adjustment length would be. I don't have the old ones anymore to get measurements. I'm guessing the stock measurement minus a few mm would do it. Please any help on replacing them would be fantastic I've watched the YouTube clips but no-one talks about how long to set the camber arm to.

      Heh. I copied the link to the video direct, instead of the thread I mentioned. But the video is the main value content anyway. Otherwise, yes, in Europe, surely you'd be expected to buy local. Being whichever flavour of Michelin, Continental or Pirelli suits your usage model.
