Hey everyone im having a problem with my new setup on my ka-t...
First this is what i have
KA24DE motor
Rev Hard Manifold,
Turbonetics Evolution 38mm (9PSI) spring
Garrett t3/t4 .60 a.r. and 63 exhaust
at the moment 370cc injectors from sr20det
n60 maf from maxima/j30
walbro 255lph fuel pump
MSD 6AL Ignition System with Blaster II coil, and MSD 2step/Rev limiter
Problem....
Car dies after any throttle weather is light or WOT it dies... UNLESS i hold the revs round 1500 for bout 15 seconds or so... i can hear the turbo winding down.
Also my a/f ratio is of the scale almost 9.2 on my wideband when im holding the throttle..
Now under WOT its perfect 11.3 round that area and driving is ok round 13.5 to 14.9 but its just that issue when i let go of the throttle..
OH SIDE NOTE some times i have a wierd throttle response i tap the throttle a bit and nothing happends....
If i dont do this it will turn off. Can anyone please give me some kind of advice i have already tried maf, boost leaks, everything... i will put vid of whats going on tomorrow. But anything till will be great thanks alot.
This is my tune right now.... if anyone can fix or try to my idle or w/e needs to be done would be great thanks
