Mine has NEVER stalled in 40K+ miles. The stalling is a bad coincidence with your pop-chargers, iirc, there was a recall of some sorts issued by NNA, regarding the Z stalling especially after pushing the clutch in after being higher in the revs while driving. Its not the pop-charger its a crank angle wire that needed to be shielded I think. Do a search guys, if you have this get it fixed, and stop blaming your intakes. BTW I never reset me ecu after any mods, I did it 1X and for about 5-6 days my car felt slow as *** as the ecu relearned itself.

Nope, just incompetent.

 

The brakes are designed to stop the car adequately regardless whether you are engine braking or not. Not all situations require "emergency maneuvers". You most certainly save gas by coasting. You can make your MPG go up drastically by rolling down hills. Not only do you save gas, you save revolutions on your engine.

I'm a professional driver. Read my first post again and think before you type.

 

You guys kill me.

 

ok.. i'm not even gonna read the whole thing..

this has happened to me a few times.. if it does stall on you while your cars still moving just put it in gear and your car should spring back to life..

+1 on the resetting of your ECU.. i haven't done it yet but supposedly it helps

 

1. how do i properly reset the ECU?
2. I emailed Jim Wolf my problem and am waiting for a response

 

coasting= out of control.

or just disconnect the negative from your battery over night..

 

Well obviously the brakes are designed to stop the car adequately, but it is going to take you a longer distance to slow down with just the brakes, vs. using the brakes and engine braking. Its common sense...1 thing slowing you down vs. 2 things slowing you down. Not to mention that there is less wear on your brakes because your rate of decelleration is being assisted by the engine.

No, not all situations require emergency manuevers. But the time it takes you to react to a situation and act is lessened if your car is in gear because you have one less thing to do before you can react to and correct the situation. That is just plain common sense.
Not to mention that an emergency manuever is used when an unexpected situation comes up. How many times have you been caught in an unexpected situation, driving or otherwise, you freeze for a sec before you act, when going at a high rate of speed you are better off the less things you have to do to correct the situation.

You obviously missed my point about coasting. Yes you burn less gas when coasting in neutral. But you burn an even smaller amount of gas when you coast in gear. When you are in gear the fuel injectors turn off (or get real close to off) and don't give the engine fuel. But the engine is being turned somehow...it is being turned by the wheels and is running under compression.
If your car is in neutral, then it is not being driven by the wheels, but the engine still has to turn somehow. It is being turned by the engine burning gas and operating the engine at idle RPMs. Yes you save on your RPMs, but if you coast in neutral you are burning more gas and using your clutch more to disengage, and then eventually re-engage.

You don't need to be a pilot to know how a plane flys.

 

ive had my popcharger for years, DD my Z (it sees all kinds of rpm's) and I've never had an issue stalling. I dont put my tranny in neutral but if i wanted to coast i'd just press in the clutch. But like I said I've never had issues in my 03 Z with the popcharger. The car is driven since it's just about to turn over 90k miles. But it's got all kinds of other mods like pullies, cams bal bla bla. i wouldn't suspect you to see an issue with stalling with just an intake. it sounds like your engine is at 3k+ when u drop it down immediately and it dies. Sounds like the idle doesn't catch quick enough - in which case JWT/Perf Nissan has a vacuum fix for such a thing. But the only people really encountering that (from what I recall) were people with light weight fly/clutch or/and cams. The only thing I've done to my Z's ecu is raise the idle 250rpms cause of the nismo cam's lope. I'm still on the stock clutch/fly.

 

oh yea.. i think i heard something like if you're going to disconnect the negative from the battery it has to be at least 7 hours.. so disconnecting the battery at night and reconnecting in the morning will probably do it..

also.. is 03performz on post 41 true? does it really feel slow for 5-6 days after you reset the ECU?

 

A car being in gear while slowing down actually uses less fuel than one in neutral - Clarkson found out when he tried to drive an Audi A8 diesel around the whole UK (or something like that) on one tank.... and I believe him, since with modern ECUs and fly-by-wire throttles, it detects that you are not in need of any petrol to keep the engine running, purely road speed will do, so it will cut off the supply. Whereas in neutral, the engine has to be kept running from continuous combustion....

 

Well then it's a pretty funny coincidence that it never did it in the 4 months before I installed the popcharger then did it twice the day I put it on and several more times throughout the next couple of weeks. Hmmm, I bet that JWT put up a fix for this on their website after multiple complaints because of a recall and not because it was the popcharger causing the problem. But you probably know more than JWT, . Just kidding man, but seriously, it's a documented problem.
