A/F Ratio too lean

Post by DC5_Jess »

Car: 2002 RSX Type S
Engine: JDM K24a (05-08 TSX) w/ Type S Oil Pump
Intake: RBC w/ CAI
Exhaust: 1320 4-2-1
Injectors: 310cc stock

I loaded two different base maps to run some short tests and found that both run too lean and cause my car to stall out at idle. I'm new to this but I understand my A/F CMD is calling for 13.91-14 around idle and my A/F goes up to 15:1 or so. I'm just looking for some help to start heading in the right direction.

Note: During the trial with the 91 Octane Calibration, I experienced smoke coming from the pipe(may be moisture in the pipe due to the car sitting for a few months) and burning in the eyes (what I'm mainly concerned about). No Knocking or Ticking occurs and I have lean protection #1 enabled on kpro.

Have you tried adding additional fuel to the tables in the areas it is running lean?
