how do you run the standard BOV with out the plumb back and have the engine not stall???

Ive tryed dissconnecting the plumb back then blocking it off, bu the engine keeps stalling. its able to rev high and make some loud noises but just wont idle..any help?? and how is that plumb back eliminated all together cause it looks gay.

AFAIK you can't, the stock BOV leaks all the time, even at idle. So you will never be able to get the car to run with the re-circ pipe disconnected. If you really want a VTA BOV then you will have to replace the stock BOV with an aftermarket BOV.

WRONG

if you want to get the stock bov working without hte plumback, the solution is not an aftermarket bov, but an aftermarket ecu...

I have a top of the range turbo Smart BOV with a Power FC and its still not perfect, the problem being that after it vents there is still a small flutter (with large snail) causing air to go both directions in the AFM causing Power FC to freak! the computer thinks ok more fuel and if large injectors ie. 720cc thats heaps of fuel and bam a stall.

Sorry no answers only more problems, my advice stick to factory BOV system (or smaller injctors haha)

im looking at putting a front cooler, turbosmart type2 BOV, gizzmo electronic boost controller and this turbosmart thingy that can be adjusted so when you up the boost the computer wont get confused. i think this should pretty much solve problems all round.

I know its weird, its not so much the injectors but the AFM reading air coming back in on the flutter and then of course the over dose of fuel.

Best of luck with all the mods, I'm sure they will all be sweet together.

You sound very sure. :thumbsup:

Have you tried it, the stock BOV cannot be used as a VTA BOV because it leaks at idle, it has nothing to do with the ECU.

well i was being a bit definate there wasn't i.. he he

what i meant to say is that changing to an afermarket bov is NOT going to fix the problem

the problem is that air that has been accountered for is being lost

Putting another device that loses air will simply return the same problem

the only way to fix it is to either:

- put a re-circulating bov on the car (stock or aftermarket)

- use a decive that accounts for the lost air, thus keeping the AFR in equilibrium

the stock BOV cannot be used in a VTA situation because the spring is too soft and cannot be adjusted.

You can run an aftermarket VTA BOV with the stock ECU, you just have to adjust it properly. If it's stalling then the spring is probably too soft and staying open too long.

The only problem with VTA BOVs is running rich during gearchanges when the BOV vents

I was running a Greddy Type S and now a GFB StealthFX, both with no problems with stalling whatsoever.

      I gotta pull you up on this. It's driving me crazy. A shutter is something that closes, like over a window or in a cmera. The word you want is shudder. That LSD is clearly f**ked. Take it to a diff shop and get it disassembled and examined by an expert. YOu might have plates welded together or something equally crazy.

      S1 rb25/s14 starting problem

      By GTSBoy · Posted

      Check the Nistune doco. There are a few assumptions being made here that might not be valid. I will list the things that occur to me: Base map. Base map for what? Base map for Z32? Then the cranking pulse width is probably wrong for an RB25. The extra 500cc of capacity might well be enough to prevent it from catching. Base map for RB25? I don't think you can load one of those into a Z32. You have to just make the settings correct for an RB25 in the Z32 base map. That is either K or the TIM to get the pulsewidth right. Loom. You bought a loom for an RB. And you plugged it into a Z32 ECU. Did you make sure that any iwre differences were swapped. From memory, there's at least a couple. And as per the others, I would suggest making sure that the fuel pressure is correct while cranking and that the injectors are actually flowing as expected. They really must come out and go on the bench, unless you do find that you have messed up as per above points. I would also suggest watching in Nistune to make sure that everything is reading correctly. That the correct binary flags are raised at the right time (like the crank signal), that there's no stupid values in K or TIM. That you have not got mismatched firmware for the ECU and/or a wrong image loaded.
