I just insatalled a t3to4 turbo on my civic si , i have full ignition system , vafc and 450cc injectors .... well since i installed the injectors the check engine light will come on when the car was cold , so i had the afc 50% lean at low and high throttle... and yes still will run rich ... so i figure i should go to 360cc injectors instead ..(i havent)

anyway ... i was testing out my civic with 11psi .. i try to richen the afct to a -10% the result tooooo rich .. so i end up putting it at -40% yet the EGTs will stay at 700c so im doing a full load tes 4th gear 100% throttle 700c egt temp ,, all of the sudden i feel like Fuel Cut ... the engine light comes on .. so i shut the engine off turn it back on ,, but with a surprise .. i have 0 throttle respond.....
and i can get the car started since .....

i need INPUT please!!!!!

thanks

 

anyone?????????????????????????

 

since no one helped heres my thoughts. First just from what ive seen most poeple running afc hack/450cc run about -35% for fuel. Second somehting similar happened to me last week,(however i am running fmu/inline, intank setup)

I was playing with boost controller and the mbc spikes .1 bar and then settles at boost level, Well i was trying to run .6 barand it spiked to 11 psi so it threw CEL and died. My first though was blown motor, but i soon relaized i had hit 11 psi so = stock map sensor, this will cause the car to die. Now heres the catch when we went to start car it woudlnt start . We called for a tow truck, but then realized i wasnt gettign any fuel pressure. Checked fuses and sure enough i had blown a fuse Its the 15 amp ignition

Just thougth it would share since same thing happened to me.

 

I have checked for fuel press and is okay , spark is okay .. what is funny is that if i hold the key on th eignition point the engine will start!!! as soon as i let go of th key it shuts down...... i have check all the fuses except relays ...... any suggestions
thanks

 

do a search on how to get your CEL blink codes, that might help you diaganose what is wrong.

Check your fuses and relays again.
