Ok so a strange question. How does the pollution gear on an R32 GTST work?

I have moved my cannister to the rear passenger corner of the car, and it still has a vacuum/boost signal from the inlet plenum and the line from the fuel tank.

I ask as on the weekend at the track my car seemed a little down on power, not much but a little. Then after 10 or so laps the engine went real flat. Scary moment for about 5 seconds until i realised engine was running ok, just over fuelling when i put the engine under load?!?!?!

So engine is way laggy, and barely makes boost, and kinda struggles to rev past 4,500rpm. No hard cut or anything, just struggles to rev any harder and blows black smoke and misses a bit...over fuellling????

So have checked all the intercooler pipes and they seem ok.Thinking it could somehow be ignition related i swapped the igniter...no go. A spark plug had a crack so in went new spart plugs. Its not coil packs as they are only 3 month old Splitfires.

I quick check of the BOV shows that it seems to be ok. No split hoses etc.

Under light throttle load as the turbo begins to spool, i think i can hear a woosh/boost leak. I also believe in the tooth fairy, so it could very well be my imagination. But it seems to be coming from just below the passenger windscreen, where i relocated the pollution gear.

So does this stuff have a check valve or something so its open under vacuum but seals under boost. Do they fail. Would a little leak from a 6mm hose cause these sort of boosting/runnign problems.

Anyone have any ideas. May have to take it to the mechanics on Tuesday if i cant get it sorted the next few days...just that i hate being a pain in the a55 by going to mechanics with these sort of dramas:(

I stripped all the IC piping off the car and it turned out there was a small split in one of the pipe joiners, which wasnt evident until you pulle don it and you saw the seam open up:(

So new hose joiner and i was back on my merry way...lol the silicon joiners are all ok, it was the token rubber joiner on the car..so throw them in the bing heap i say...

    • Yep, the closest base tune available was for the GTT, I went with that and made all the logical changes I could find to convert it to Naturally Aspirated. It will rev fine in Neutral to redline but it will be cutting nearly 50% fuel the whole way.  If I let it tune the fuel map to start with that much less fuel it wont run right and has a hard time applying corrections.  These 50% cuts are with a fuel map already about half of what the GTT tune had.  I was having a whole lot of bogging when applying any throttle but seem to have fixed that for no load situations with very aggressive transient throttle settings. I made the corrections to my injectors with data I found for them online, FBCJC100 flowing 306cc.  I'll have to look to see if I can find the Cam section. I have the Bosch 4.9 from Haltech. My manifold pressure when watching it live is always in -5.9 psi/inHg
    • Hi My Tokico BM50 Brake master cylinder has a leak from the hole between the two outlets (M10x1) for brake pipes, I have attached a photo. Can anyone tell me what that hole is and what has failed to allow brake fluid to escape from it, I have looked on line and asked questions on UK forums but can not find the answer, if anyone can enlighten me I would be most grateful.
    • It will be a software setting. I don't believe many on here ever used AEM. And they're now a discontinued product,that's really hard to find any easy answers on. If it were Link or Haltech, someone would be able to just send you a ECU file though.
    • Yes sir am asking is there possible way from aem tuner from wiring pins 
    • Have you checked cam to crank timing and confirmed balancer marks are correct?
