Been trying to get at good base map for my setup before installing bigger turbo this winter.

Current specs are:
Fully forged sr20det
BC 264 cams
detchwerks(spelling?) 810cc injectors
HPX Z32 afm
stock turbo @ ~9psi
3" exhaust
Innovate MTX-L

I adjusted K constant/latency for decent AFR with O2 disabled.

Ive done a couple of runs and looked at the logs. It runs really rich under load without reaching those areas in the map.

What i think i need now is a nudge inte the right direction to get further in the mapping.
Is it my scales that are completely off? i dont know where to go from here.

I never hit WOT in the log because when i do AFR dives towards 9 and lower.

Any help is appretiated.

poking around the map, is my TTPmax completely off the chart perhaps?

Turn your O2 sensing back on...

Hold about 2000rpm in closed loop area of the fuel map. Watch your long term/short term trims and adjust K constant until they reach about 0%

Your AFRs should then be showing about 14.7:1 on the wideband. After doing a short run see how far your TP goes and rescale the maps to the maximum TP value

After this change your fueling to achieve your target AFRs (normally around 11.5:1 depending...)

TTP max is fine. That is the default setting when changing injectors and ticking that box
