Attempting to tune a friends s300v2 but having some issues controlling the AFR.
Ill provide some info:

engine: ls/vtec

typeR pistons, stock rods and crank,
HEAD is ported and polished, with stock typeR valve train
Megan cam gears, skunk2 manifold, TypeR header,

high flow fuel rail, WALBORO 255lph pump, RC 440cc injectors.

fuel pressure guage reads 55psi constant
I have a 3 bar Speed Factory map sensor and the oem map sensor

ECU IS A S300v2

the current fuel map template is set for the itb setup.

I cant seem to get the AFR under control. its rich or its rich.

I think maybe the fuel system is to beefy for what the set up is.
I was attempting to run an MSD ignition set up but the car wouldn't start so i switched back to the stock b16 distributor and it cranks and runs like a champ.

MOSTLY WOULD APPRECIATE SOME GUIDANCE IN TUNING THE S300 SETUP WITH THE LAPTOP.

I JUST DONT KNOW ENOUGH YET ABOUT SETTING MAPS WITH THIS PROGRAM.
