I was doing about 90 on the highway and about to turn off onto another highway and in between shifts it just died. I was halfway into the turn and almost hit the guardrail because of the unexpected loss of steering. scared the s--- out of me. At that speed it would have been the end of me and my z. Im not sure if the popcharger is worth it. Still wondering though since its the first time. ive hat the popcharger for a month now so the ecu should be well adjusted by now.

 

NOT WORTH IT. happened to me. i just dont understand why its worth the insecurity of failure at any time. believe me i loved it when i put it on but within an hour my car was dead holding up rush hour traffic and buses. driving without confidence sucks, long road trip, around town, whatever. never a good time.

 

what causes the car to shut off? fuel cut?

 

Wow, this is kinda scary. I'd like to reiterate the above post, anyone have a clue why this is happening? I've got one installed and I drive up and down a large hill on a daily basis. I'd hate to go off the side because it stalls out.

 

This is pretty old news..

It usually happens after a popcharger install because the ECU has yet to learn the your new air flow characteristics.

You can either continue to drive it and the ECU will eventually learn or if you are impatient, reset your ECU forcing a re-learn. This should solve your problem..

damn, i never knew this happens. Why would anyone have one in their car if this happens?!

 

i too was worried about this when i recently installed it. I read a couple of posts about it failing ONCE and ONLY ONCE on people's cars then it was completly fine after that. Well right after i installed it i did a ECU reset and NO problems have EVER occured. Has not stalled once and ive had it for over a month and exactly 636 miles on it(set the tach to see if i had any problems and at about how many miles). I have not heard of anyone having it stall randomly after they reset the ECU right after the install. U should just do it anyway to be safe and its really not that hard.

i did the entire process and it worked out fine.

 

I've had mine on for 4 months now and it never stalled...hopefully it's just an ECU fluke for you guys that have had it happen...but it seems to be rather isolated instances....from what I've seen, about 4-7 per 100? Is that correct?

 

Its been a month, Guess my ecu is a retard and takes a while huh...LOL Ill try resetting in manually and see. like i said its only once and im going to give it one more chance.

 

Not that I'm disagreeing with you about the numbers, but it seems to me that if they're accurate, that's really high! Can you imagine if 4 percent of the Zs had random catastrophic tire blowouts or steering linkage failures? That would be a huge issue.

Has anyone who's experienced this problem contacted JWT to see what they say?

The first person that destroys their car at the hands of a JWTPC induced engine stall is going to sue the daylights out of the company.

I for one am avoiding intake mods until next summer. Then it's Vortech time!!!

 

happens for that reason and also partially because of turbulence.

FWIW, when you're slowing down, don't just clutch it or shift into neutral... downshift until you're <50mph and it shouldn't happen. If you were downshifting when I stalled... DOWNSHIFT FASTER!!!! (I had this problem bad with my Z32 because of the location of the intake and MAF right inside the opening of the bumper... it'd get so turbulant at speeds above ~60mph that if I just shifted into neutral coming into a toll booth, it'd want to stall... went away when I started downshifting.)

Just my $0.02

 

Well, I would consider it more of a nuisance than a serious problem like a tire blow out...however it could be serious if the conditions/situation were just right.
As far as mods go, I would say 4 out of 100 people with problems is LOW. Look at the track record of some of the other mods...yikes!

Anyhow, it is still a problem that should be looked into, or at least made as general knowledge...as in : You may experiece this if you don't do that...et cetera..

 

Guys,

It has not happened to me yet (knock on wood), but if our car stall. Can you still steer the car when the engine is off (split second). It should be the same as when a car is broken, and somebody is pushing it?

Might be scary if you are going top speed. Yike now I am worried.

Ive had the Popcharger for months and i havent seen anything like this. You may have more problems than the popcharger if your car is shutting down at speed.

 

funny.... I run my pop charger on the street no problems...

on the track I just put a K&N Dry Charger over the velocity ring... no filter on it at all...

hrmm.. something else is up... did you do the crank position sensor TSB?

 

well if u have ever stalled a car "normally" you would know that u get NO power steering and it just feels horribly heavy. U can still move it and it might be a little easier to move the wheel at higher speeds but it is still pretty dang hard and heavy to move it. If you are on a turn then....

 

happend like 3 times to me and has been great since. not fun when it happens but it should stop and then you can just enjoy it.

 

i have around 3k miles w/ my popcharger...not a single problem

 

Mine is a 4.5 that tsb doesnt apply and i didnt have any probs before the charger and the car has only stalled once. i was in 4th at pretty high rpm and was about to shift to 5th pushed the clutch in and i saw traffic up ahead so i decided to wait on the shift. so the rpm's dropped in neutral from lets say 5500 and as it dropped it kept going all the way to zip.

 

ive had mine on for thousands of miles and i drive on the highway alot so my average speed is pretty high. i have never forced an ecu reset and i have never had any kind of stalling issues.

were you by anychance throwing it in neutral at a high rate of speed? or holding the clutch in longer than normal while going fast?
