dont no if it helps...but my talon did the same thing...it came down too out of time and vac leak...but i fixed it and it idled fine...
Turbo b16 dying when warm
I have a turbo b16 setup that i just finished and once its warmed up when driving around when ever i get out of the throttle to slow down and the clutch is in the car shuts off on me. i was messing with the fuel pressure regulator taking the vacuum line off of the intake mani and when i do it doesnt die everytime i press in the clutch to slow down. it did once but not every single time like before. could this be that my fuel pressure regulator is bad or what else could cause this?

try running some e85 in it. if that helps your idle, you're too lean. if it hurts your idle, you're too rich. either way it seems as if you tuned your car for only top end and forgot about the rest...

thanks to both of you for the help instead of criticismIts more than likely that his tune for the other turbo was when it was warm outside, and now that its cold, it is not getting enough fuel at idle, due to the ECT and IAT adjustments not being set up thoroughly for vast temp differences. I don't think the size difference of the turbos is going to make a big difference on fuel at idle. Of course it will make a big difference when the boost comes on.
nismojunkie: i know youve put every turbo size possible on every motor (even hondas cuz their so nismo) and know what turbo will work and what wont on each said engine. i should believe you cuz your certified but for some reason i dont because of a certain tech question by you http://www.tennspeed.net/forums/showthread.php?t=5505.
but thanks anyway
I would not do this. E85 will require you to run 20 to 30 % more full to run the same air fuel ratios on 93 octane. It needs to be tuned for the e85 to run correctly. I think it would actually be E70 right now though.try running some e85 in it. if that helps your idle, you're too lean. if it hurts your idle, you're too rich. either way it seems as if you tuned your car for only top end and forgot about the rest...
ill wait to see if the tune fixes it b4 i go putting that shit in their but as for the tune its not for this setup so nothing was forgot about. thanks for the input manetry running some e85 in it. if that helps your idle, you're too lean. if it hurts your idle, you're too rich. either way it seems as if you tuned your car for only top end and forgot about the rest...
i never even thought of thisIts more than likely that his tune for the other turbo was when it was warm outside, and now that its cold, it is not getting enough fuel at idle, due to the ECT and IAT adjustments not being set up thoroughly for vast temp differences.

very good sir. it was tuned in mid sumer when it was hot as FUCK. i remember cuz the car had no ac and we were driving round sweating our nuts off when we were tuning it. And it is cold as shit outside now. you my friend are very insightful, thanks greatly. you have a thing or 2 to teach nismo
it is if its not getting enough to spool the turbo enough.Its more than likely that his tune for the other turbo was when it was warm outside, and now that its cold, it is not getting enough fuel at idle, due to the ECT and IAT adjustments not being set up thoroughly for vast temp differences.

An "ebay" T70 is not nearly big enough to cause that problem. Its not even 70mm, which still wouldn't cause that problem. You can bolt on a huge turbo on a complete stock civic, and it will have no problems idling. Several years ago, most people were running 57mm to 67mm turbos on Hondas using the stock 240cc injectors, and using FMUs to raise the fuel pressure to make them flow more like 500cc injectors. These cars had no problems idling, as the factory computer was tuned very good by Honda of course to control idle in all conditions for the stock injectors.it is if its not getting enough to spool the turbo enough.
wow...i think it was said several times, dont drive it...tune. decel air/fuel trim.
