S14 SR20DET Cold start/base map help
Posted: Sat Aug 02, 2014 12:27 pm
Hey all, trying to get my car running again after a rebuild so I can break the engine in and get to the dyno. Having some troubles with cold start, and with the car trying to die when I come to a stop.
Setup is as follows:
s14 SR20DET
full forged internals, Supertech 9:1 pistons
BC Stage 2 cams
Z32 MAF
MSD 96# (1000cc) injectors
GT3076R turbo, external wg
full 3" exhaust
92oct gas
The car seems to idle good once I get it started and it warms up a bit. Nistune shows it idles about 15deg timing at 850-900 rpm around 14.5 afr
When I come to a stop sign, the car tries to die, but I can keep it running with the throttle and then it evens back out after a sec.
Just looking for someone to peek at the logs and the tune and see if I have anything really crazy going on that I shouldn't.
I pulled about 3deg of timing in the low load areas just to be safe.
I have the knock flag turned off in feedback, but Nistune still shows a knock code showing up. Do I need to put a resistor in the plug?
I'm sure I have more questions, but that's about all I can think of now, have about 10miles on the car so far, and no crazy noises and good vacuum, so that's a good sign, right?
Thanks in advance for your help guys!
