its covered a million times why no bov causes stalling

Someones a bit short... a million times hey?....

My manual 33 is doing the same thing this week, pull up at the lights, clutch in, and the revs drop right down, they come back up a bit but idle is a lot lower than it normally is.

try new plugs in. when i first got my 33 it was stock (except for the front pipe). when i backed off after a quick squirt it would bog down, and if i did it then put the clutch in and idled to a stop it would stall. i put new plugs in and it solved the problem.

There are a few reasons.

Firstly..nissans rely on a plub back BOV. The stock ECU is mapped to it...it expects that extra poofteenth of air on idle return. It's a tempremental issue dependant on things like the state of your AFM, TPS and AAC valve. Some guys can get away with it..some guys wont. Some guys will tell you that it runs ok but it really doesnt and they just love the futters.

If you insist on running VL style with no BOV then clean your AAC and AFM . If it still happens then you can "tune" it out with a SAFC or PFC.

Not really, it has been covered many times in the past

Im not going to type up another post about why as i've done so many times already.

      If you want to do the wiring, the GTT engine ecu has the same pinouts extra that the seperate TCM in the NA car has. You can literally grab the wires/pins that lead into the Seperate TCM and wire them into the corresponding pins in the GTT Engine ECU. You could then in theory Nistune it. I realised this when everyone put it in the too hard basket and I actually looked at the f**kin R34 manual. This is after I had previously had a seperate aftermarket TCM controller in my original N/A chassis car and a very built gearbox from a GTT, running a seperate Haltech engine ECU. I ran into this issue when I re-shelled the car into a GTT shell, so my aftermarket TCM was no longer plug and play, because the loom/modules were not present. I was pretty livid when realizing just how simple the original fix actually was. It sat for 3+ years at various workshops trying to find a solution. In practice none of this is a worthwhile idea for a lot of reasons, generally surrounding the shitness of the NA auto, the autos in general that come with skylines, and the NA engine and lack of gains. The gearbox is specced for the 2.5L N/A and barely at that level. If you have to pay anyone any money to do any of this, that is money spent on manualizing the car and it's not even close in terms of a comparison. Learning to drive manual is simpler than going through the pain of dealing with the N/A gearbox and he'll have fun to boot.

      Semi-correction to my blanket statement that you can't bend rubber hoses. It seems that you can get most of a result, by doing as this guy does. I wouldn't promise that the bends will stay in the hose forever. I think if I found they wouldn't stay, I'd get a larger hose and cut some 90掳s out to go over the bends I wanted to be in the smaller hose, as a reinforcement.

      Just a heads up. Mine has just failed. When i turn the car on it just reboots everytime then the word "Android" shows up then goes to a black screen. I've aksed the company i got it from for some help but it's passed their 90 day return so they wont help. I have to swap back to my old system this weekend 馃槶

      Does the car have to stay auto? If so, you might be looking at a ZF swap in future.
