O2's falling off
Posted: Wed Apr 25, 2012 1:04 pm
Hi I am new to Nistune and i have an odd problem with my set up.
I had recently installed new 750 injectors and a new 2871 turbo. I pulled up Nistune
I first rest the MAF for a Z32 and then re-sized the injectors for my set up, but when i first tryed to start my car
it was hard to start, I actually had to give it some throttle to start and when it did it was fine at first.
my innovative read around 12.5 so i adjusted the K and win i got to 14.5 it idled there for about 5 to 10 seconds
then the idle dropped off and the o2's were reading between 25. to 32. I have tried the adjust the latency and the K constant to get a stable idle but with no improvement I know my fuel pump is good and I have a adjustable pressure regulator with a gauge. If any body has any ideas i am open for any thing.
here is my setup if it helps
S14 Sr20det
Isis 2871 turbo
1mm over CP pistons
head studs
cosmetics head gasket
750 injectors
Z32 MAF
ported head
stock intake
stock down pipe
synapse blow off valve
reticulated
haven't found the wall with the stock down pip yet
If any body need any more info just let me know
