Compression or leakdown will confirm if its a problem with blowby.

Indeed.

I also wouldnt be worried.My oil comes out black and it doesnt take it long to do so.

When i bought my car it blew black smoke on 7psi with the stock computer and a 3.5'' catback exh with pod.But with the pfc,12psi will occasionally puff black smoke @ 182rwkw.Thanks to jim's tuning at CRD.

Like morgs said,if your worried about the smoke do a leakdown test to determine whether or not you actually have a cylinder pressure issue.And hopfully it will help to shed some light on the situation.

After talking with Eli and a number of others, we are going to leave it in there for another couple of weeks, dump the oil and replace it and the filter and monitor it for a week..

reason for leaving it is that if it is in fact sludge buildup it will hopefully get all of it free - suspended in the oil and get rid of most of it in 1 go..

I will also be switching to Motul as most people on here recommend..

i do realise people say my oil is fine.. but I don't like the fact that in the space of 4 days - i've completely saturated it with carbon..

cleaning it out is a good start rather than leaving it in there for more to build up or overcome it's suspension properties..

After eduacting myself in the past 2 days - I think there shouldn't be any issues.. when I get it serviced next i'll probably get a comression test done and this should give me an indication of any piston issues..

i'll keep everyone posted..

As for the A/F ratios - i'm thinking about looking at a SAFCII + R34 GT-T intercooler for the summer as I know how hot it gets..

For the popping issue - I think maybe a Split 3" dump pipe might help resolve this issue..

      RB25DE NEO with Haltech ECU

      By Haggerty · Posted

      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.

      spot the stagea

      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.

      Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.

      R32 GTS (RB20DE) Injectors Replacement

      By GabsReDeal · Posted

      In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).

      ECUtalk pages don't mention they support the ABS computer (consult port has more than one CAN), so you might just need a different scan tool. But, I would expect ABS is a different light to the brake warning/handbrake light, do you see an ABS light come on for a few seconds when you turn the key from ACC to IGN? But since you said: I'd have a look at the ABS sensors in the rear hubs to make sure they are not damaged, disconnected etc.
