Do a couple of hard launch, then pull over. If you can smell something similar to brakes (assuming you didnt stand on the brakes:)) you probably got slipping clutch.

Basically the engine will be accellerating, but the cars accelleration will be very sedate by comparison. I remember when mine went, I would pull away gently and all would be ok, if I tried to give it too much stick, if felt (and was) alot slower even though the engine revved hard - if you know what I mean.

Another dead giveaway is smoke coming out the front of the car near the back of the front wheels after you have done your launches (well mine did anyway).

Mine slips when I slap third gear, however slapping second causes wheel spin until around 90-95kays where third is.

I've got one of those purple looking pressure plate ones that has 30% more pressure. Its not the best I must say, heats up to quickly and slips, even since day one.

I tell ya what... it must be scary doing 90-95km/h with the back end out of control, I hate it when just doing like 20-30km/h hehe.

Unless I drop the clutch from >1700rpm in 1st gear I can't break traction any other way (or gear). Can't wait to get rid of these 225's and throw on some 255's on the rear it'll be unreal.

Mine did with stock cooler, got a FMIC and it held boost all the way to redline.

Horsepowerinabox have a write up on the stock cooler saying it drops something in the range of 7psi at 6000+rpm, its on the cooler upgrade for R33 pages, worth a look.

If what they say is true, when you are reading 10psi at 7000rpm, your turbo is actually making 17psi as boost is measured at the plenum.  This is probably why its not a good idea to boost over 10psi (or try to) with a stock cooler;)

Is that an article in a book or a web page?

My thing spins at any speed in first gear, as soon as it hits boost it spins. Its due to my tyres. There 255/40/17 but they are hard as, tyres dont feel sticky at all. Need some new ones. Anyone got any cheap?

I've got the same core.

If I set boost above 13psi with the standard turbo I get boost drop with the ebc in manual mode. With the EBC in Auto it will hold boost all the way but it does waver slightly and makes slightly less boost in lower gears, nothing the a manual channel of scamble can't fix though.

With the bleeder I experienced exactly the same. I did notice that after fitting the fmic 3rd gear felt stronger and consistent where as with the stock IC after a few hard gears the heat soak must have set in and power would start to feel flat in the higher gears.

    • If as it's stalling, the fuel pressure rises, it's saying there's less vacuum in the intake manifold. This is pretty typical of an engine that is slowing down.   While typically is agree it sounds fuel related, it really sounds fuel/air mixture related. Since the whole system has been refurbished, including injectors, pump, etc, it's likely we've altered how well the system is delivering fuel. If someone before you has messed with the IACV because it needed fiddling with as the fuel system was dieing out, we need to readjust it back. Getting things back to factory spec everywhere, is what's going to help the entire system. So if it idles at 400rpm with no IACV, that needs raising. Getting factory air flow back to normal will help us get everything back in spec, and likely help chase down any other issues. Back on IACV, if the base idle (no IACV plugged in) is too far out, it's a lot harder for the ECU to control idle. The IACV duty cycle causes non linear variations in reality. When I've tuned the idle valves in the past, you need to keep it in a relatively narrow window on aftermarket ecus to stop them doing wild dances. It also means if your base idle is too low, the valve needs to open too much, and then the smallest % change ends up being a huge variation.
    • I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.
    • AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.
    • As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.  
    • It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack.
