Have read the threads by Brain and others and can,t seem to perfect the curve and seem to be chasing my tail. Has anyone gotten this curve down? I find that my idle AFR after warmup is about 14.5 but by the time I get to work its in the 12.5-13.5 range. Thats temp change from 56F-90F but my cruise afr seems to always be changing aswell from where I want to lean. I get closer and closer but always end up back where I started. Can you guys post up examples of your Correction Curves? Firmware is 3.3.X on a DIYPNP. Any input would really be appreciated! Thanks!

Idle gets richer but cruise gets lean? Issue may lie elsewhere. Pick a nominal air temp to set as zero correction. Then, when air is close to that, tune VE table when coolant is above 185*F and WUE is at 100%. Then work on temp related corrections once operating temp settings are dialed in.

log it.

is it due to enrichments or corrections? for example: is Gair increasing too much as temps increase and causing the rich conditions?

Ok so i notice that my WUE has my idle in the 15s which is leaner than warm, but once driving during WUE it runs richer which is expected. The idle gets richer after WUE and then at the end of my log the idle is high 12s low 13s AFR. To me everywhere seems to stay close to my targets except idle with temp changes.
