Hey all,

need help. Tried installing a HKS SSQV to the rb20 in an AUTO where the mount for the stock BOV is located. Blocked off the return hose and connected all lthe necessary hoses. But when it came to driving (read:crusing) it jsut stalled when ever the revs were changed below 3,000rpm. You could jsut hear the BOV releasing then the engine jsut shuts off.

The seller off SAU tried resetting the ECU via Disconneting the battery and all but the stalling continued. ALl means were considered but need more info and help.

Any tips be great cheers all!!

Err I'm not sure how a BOV is suppose to work on an auto but with a manaul it lets off when you let off the gas, i.e when throttle body is closing.

So hows it suppose to let off if you just keep your foot on the accelerator? Maybe that has something to do with it.

You might want to try and adjust the spring tension on the valve so it opens easier under low rpm, BOV's on autos can regularly cause stalling if not adjusted properly

Just keep adjusting it and rev it to 3000rpm and if it goes back to idle without stalling or struggling it should be fine

What boost you running?

Sorry to hijack thread but.. when you switch from a plumb back to atmo blow off valve, does it not play havoc with the air flow meter taking into account having the plumb back, with the a/f mixtures? Like mine, when i disconnect the plumb back hose the idle is really rough... stalling occasionally..

Makes sense..

What I meant was the afm has inbuilt compensations for the air coming back through the plumback, when you take the plumback away the mixtures aren't right because of those compensations..

So yeh - the electronic means to fix that would probably have something to do with that... right?

Tnanks for the helpful advice, reckon gettin the HKS EIDS is teh way. But my mate is running an atmo BOV on his auto, retaining the stock BOV, and using the cooling pipe near the Air Box. Is this a simple soluyion or will it have a future effect?!?!

cheers all

    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.   
    • I feel there must have been a FB/insta post and the weekend did not start well at all I hope everyone is all okay
