i was wondering if anyone has any ideas, i got an integra b18b1 with a td04 a 10:1 fmu and 330cc injectors and doulble headgasket (stock ones) and i'm running 10 psi, but i can not get rid of detenation, anyone have any ideas?

Thanks

I'm not the king of turbo, but i would think you had a lot of options.
1) you could lower the boost
2) you could get bigger injectors
3) you could get some sort of "real engine management"(ie smc afc...)
4) you could get real engine management(ie zdyne, hondata...)this is of course the best route, but i guess in any case you should get bigger injectors.
just my common sense thoughts. hope they help and good luck

 

get rid of the FMU and get larger injectors...plus tuning of course

 

get an inline pump NOW!~

What fuel pressure are you running at?

 

intercooled or not? and that setup intercooled should be good at 10psi, what is your timing at?

 

tell us your whole list of mods u got.

 

my list of mods:

tdo4/10:1 fmu/255 fuel pump/stock probe turbo injectors (supossely 330cc)/double headgasket/and timing is set at stock (16btc) only running 10psi/ngk plugs (colder) but i can't get rid of the pinging at about 1/2 to 3/4 throttle

 

You need a intercooler, your charge tepm is probably to hot

 

sigh there is nothing wrong with running an FMU......u just have to set it up correctly. Dude you need an inline pump!!!!!!!!!!!

 

i already got a fuel pump there is no need for an inline one, it can't pull anymore than the one thats in there anyways. I got an intercooler i should put it on and see if that works. Thanks for the info

 

yeah 10psi non-intercooled is most likely your problem. I honestly wouldn't run more then 5psi w/out a intercooler

 

what's the highest psi your 255 pump is rated for? you're asking 100 psi + base psi from that pump, maybe it's not providing? high psi inline pump

i would also try retarding base timing as stated by someone. are u sure your not missing instead of pingin? (not tryin to dis u or anyting)

got any air/ fuel data or egt?

 

i'm not sure of the psi for the fuel pump its a 255 from a mustang, i'll have to check on that, i retarded the timing a couple of degress, but it still pings, i got an air/fuel gauge at idle it bounces back between lean and rich, once i hit boost its rich, so everything is working. thanks for the help
