i bet you car when into lean idle. need to tune it to give more fuel when the throttle plate is shut. what type of ECU are u using ?

 

hks 280's and using aem ems

 

well that sucks, maybe you need a better tune sir.

 

yep he definitely need a better. If you have a wide band. look at as you come the stop, you will see the AFR dip pass 14.7 like 15+ afr. car choke and stumble. the rpm drop and go back up. i have 272/272 using autornic. my idle AFR is 13.1. when i come to stop, i tune the ecu to give more gas so the AFR won't go pass 14.0 AFR. Now with 280/280 it even worst.

 

sorry to bring this up, but Im going through the same problem.
Hey OP did u even find out what causes it to die? anyone know?

 

Not sure. This was my old setup and it spun a bearing so I never got to fix the issue. I did have this issue on my new setup due the idle compensation which needed some fine tuning. This problem can be caused by a lot of stuff.

 

I call the tune. My first tune kept dying shifting out of gear or coming to a stop. Eventually I called my tuner and had him look at it again. Problem fixed.

 

I currently running into the same problem. Although mine only happens after a boosted run. In my case I'm going thru some of the mechanical setups first. I found out I have the unpainted Tial BOV spring and with 280 cams I have about 10in of vacuum. So I need the black spring. Of course this is causing the BOV not to open and cause compressor surge. This might be the problem or not. I'm waiting for the new spring. After that I would have to check the MAP sensor or the TB.
