hey guy first post so gimme a break lol, I just got a 32 gtst w rb20,ok first thing is I plumbed the catch can properly ie t'd the pipes on the rocker covers and ran that to the can and the other pipe to the pcv, now its sucking air from where the dip stick is, to the point its still sucking when the engines turned off I know vaccume is good but geese, also its having trouble idleing, it revs erraticly sometimes and pops and farts, it has an exhaust leak at the dump would that do it? Any help will be appreicated, cheers.

your setup looks right, is ur dip stick poping out and if so it could be blow by (if u dont know what blow by is it is when ur rings r on ther way out and the boost pressure makes it way pass the rings and presurise the sump) if u think its that turn ur boost down ur boost might be to high for the age of the motor. and if u dont think its that f**ks me what it is ;p

Don't think so. The PCV should connect directly to the RH (driver's) rocker cover (as Nissan installed it). The other side of the can then connects to the intake pipe, just in front of the turbo.

Oh ok, so the pcv has nothing to do with the catch can? Also the idle things starting to annoy me :s the tps isnt working properly, it will read 10.8v or 13.4 nothing in between. Oh yea and it had engine oil inside it.

You are sucking the catch can gasses into the plenum right? Put the PCV back and plumb the catch can into the turbo intake like it was before you stuffed around with it.

Yea its plumbed into the pcv, the can had a breather on it thats why I stuffed around with it lol. I just read an article about pcv valves on rb's and the fact there only open at idle/vacumm oh well lear from ya mistakes ay. Anyone with ideas on the idle situation?

Ive plumbed it properly now, plenum side to pcv, exh side to can, can to intake, now its hunting when I pull up, ie decelerate to idle. It pulls fine, turbo spools everything is good except the idle. Im thinking cas or someyhing :/

Have you checked for all your vac lines for leaks?My 32 almost stalls every time I pull up, and another guy I know his 32 did the same until he got a nistune.Maybe take the throttle body off & give it a clean out. Just an idea.

      Boost level and torque curve

      By Lithium · Posted

      There is a LOT of stuff that can be done, it all depends on how much time and money you want to spend on doing in.  Not all ECUs will be able to do it, and the more control you need the more time and knowledge needs to be put into making it work.  If you're willing to spend the time and money and have the right hardware and skills involved there's a lot that can be done.

      I am impressed with all this level of adjustment. I didn't expect all this possibility

      Boost level and torque curve

      By Lithium · Posted

      Correct.  In the case of the 500kw dyno plot I showed you the car actually runs two boost control solenoids for boost control and a 5psi wastegate spring.  It allows me to control how much boost pressure is applied to both sides of the wastegate valve at any point and fairly accurately control boost target as a result. I've tuned it so that it's able to target anywhere from 5psi to 25psi depending on what's needed.  The target tables I've set up in that car are Gear vs RPM, so every gear has potential for a different boost (and torque) curve.   First and second gear have quite low boost targets, third gear actually has different target boost all the way through the rpm range as it's a stock RB25 gearbox - the boost targets have been chosen to maintain a peak of 600nm (what the owner has set as the maximum torque he's happy with putting through the stock 3rd gear) but it carries that to the rev limiter.   The boost curve to achieve that is something of a ramp up, then hold, then ramp up again and the power curve looks more like a flat line haha.

      so you can decrease or increase the boost depending on the diet as you wish?     by acting on the wastegate?

      That's torque and power, it's all from a single run.  The boost curve is "held back" from it's peak target in the 3500rpm to 5000rpm range from memory, so it ramps hard to something like 18psi then climbs more progressively to 23psi nearer 5000rpm.   It makes the torque (and power) ramp more "natural" and less hard on parts and traction, it doesn't feel artificially held back.
