hey fellaz, just asking for some help on some stalling issue's im having with my r32, mods are as follows, apexi filter,trust fmic,hybrid controller, trust turbo back 3inch exhaust, high flowed injectors? 300zx single turbo (t3/t4) ? stock ecu oh and walbro 450pump, ive cleaned throttle butterfly, iac valve, air flow meter , adjsted the timming and idle itself, the car will idle fine just occasionaly stall sitting still, but 9 times outa 10 it will stall whilst decel to a set of lights, if i dont heal toe it, any other suggestions/procedures to rectify this problem?... had it dynoed, pump cuttin out underload and ecu causeing it to run lean, plus ignition timming at 30deg advanced !! since fixed this problem. timmin @ 15deg now btdc, made 160rwkw under these conditions, i wanted to get idle fixed b4 returning for another run, any help would be great my nissan brothers :D

no i dont, it used to run a chipped ecu which caused the first motor to shit itself, i then had a spare auto comp which ran it fine but ignition timming was way off, i got a stock manual comp today, i have a blitz bov on it, its not plumb back, i realise it would overfuel on deccel but i figured with the amount of skylines out there with none plumbed back bov's i thought it couldnt be the problem, all the turbo cars around me atm have vented bov's but no stall issue, am i wroung to assume this isnt the problem?

Its in the top 10 of most common problems, so its a problem arite ;)

Search these forums, probably one post on average a week about stalling :D

And its only related to AFM equipped cars. Not all turbo cars run an AFM to begin with, some run aftermarket management etc.

So its not good to assume that because everyone else is, you should too :nyaanyaa:

I would put a plumb-back on it and id be 99% confident it will be fixed.

would it cause any issue's to plumb back to blitz bov? the bov kit came with a blitz adapter pipe etc, i would like to retain it as its worth abit and saves me having to source another plumb back item, i could make a small pipe then silicone hose it back to the inlet to the turbo just after the air flow meter? or any reasonably priced after market plumbback items? i would like it not to stall but still retain some music on gear changes :D

      Fender flare widths across front/back of car

      By AdiR34 · Posted

      Hey y'all! I'm curious about how y'all go about widebodying your cars. I noticed that when running a square setup, my front wheels are a bit more tucked in than my rear wheels. Not by much, maybe 5-10mm. This leads me to wonder - when I widebody, should I use narrower front flares and wider rear flares? I found a set of 40mm rear flares that I really like, and was thinking of pairing them with some 18mm front flares, but I don't want the car to look strange. How have others done this? Note, I'm in a sedan. Thanks!

      And if it was anything other than an auto tranny part, it might be a problem. But seeing as all auto trannies belong in the recycling bin, it's fine.

      Stock rb25det neo questions

      By dbm7 · Posted

      All the schemas I can see, indicate your typical setup of ATF 'cooler' (read: heat exchanger) in the bottom radiator tank..ie; https://nissan.epc-data.com/stagea/wgnc34/5413-rb25det/engine/214/ ...but I can prattle on a bit here. These trannies have a thermistor in the sump ~ the TCU reads this and 1. bumps the line pressure up when the ATF is 'cold' and 2. prevents the TC lockup clutch from operating, until the ATF comes up to minimum operating temp (keeps the ATF 'churning' through the TC so it heats up quicker) -- trigger point is around 55C. In these conditions, the engine coolant temperature rises faster than the ATF temperature, and also helps heat the ATF up, which is why it's best to think of the in radiator tank setup as a heat exchanger ; the heat can flow in both directions... ...with these trannies, the 'hot' ATF comes out the front banjo bolt, flows through the cooler/heat exchanger, and returns to the box  via the rear banjo bolt. This gets a mention, due to the wildly different opinions wrt running auto trans fluid coolers ~ do you bypass the in radiator tank altogether, or put the cooler inline with the in radiator tank system...and then, do you put the additional cooler before of after the in radiator tank system?... ....fact is the nominal engine operating temp (roughly 75C), happens to be the ideal temperature for the ATF used in these trannies as well (no surprises there), so for the in radiator tank system to actually 'cool' the ATF, the ATF temp has to be hotter than that...lets say 100C -- you've got 25C of 'excess' heat, (slowly) pumping into the 75C coolant. This part of the equation changes drastically, when you've got 100C ATF flowing through an air cooled radiator ; you can move a lot more excess heat, faster ~ it is possible to cool the ATF 'too much' as it were...(climate matters a lot)... ...in an 'ideal' setup, what you're really trying to control here, is flash heating of the ATF, primarily produced by the TC interface. In a perfect world, wrt auto trans oil cooling, you want a dedicated trans cooler with builtin thermostatic valving - they exist. These should be run inline and before the in radiator tank system ~ when 'cold' the valving bypasses the fin stack, allowing the ATF to flow direct to the in radiator tank heat exchanger, so it works 'as intended' with helping heat the ATF up. When 'hot' (iirc it was 50C threshold), the valving shuts forcing the ATF through the cooler fin stack, and onto the in radiator tank heat exchanger...and you sort of think of it as a 'thermal conditioner' of sorts...ie; if you did cool your ATF down to 65C, the coolant will add a little heat, otherwise it works as intended... ...the 'hot' ATF coming from the front bango bolt, is instantiated from the TC when in use, so all/any flash heated oil, flows to the fluid-to-air cooler first, and because of the greater heat differential, you can get rid of this heat fast. Just how big (BTU/h) this cooler needs to be to effectively dissipate this TC flash heat, is the charm...too many variables to discuss here, but I just wanted to point out the nitty-gritty of automatic trans fluid coolers ~ they're a different beastie to what most ppl think of when considering an 'oil cooler'... /3.5cents
