AFR Table for full-time Open Loop? Any EFILive users out there with modified B3605 table for full-time open loop? The factory settings look overly rich. If so, can you please post up your table and describe why you modified it as you did and how it works for you?
An analogous modified HPTuner table could be helpful if you have that. Thanks in advance for any help.

I run OL MAF, part time CL & part time OL. Even in OL, I (think) it references the VE table because the A/F mix can still lean it out using the VE table. The OL fueling table is set as high as 1.04 in the "normal driving" rpms & MAP areas. CL & OL are selected by increasing the ECT temps above where the car normally runs on table B4205. PE remains PE. Here's the tune:

That looks like a good place for me to start - thanks. AFR's are much more reasonable than the factory settings. Any particular reason for retaining PE instead of just scaling the table richer in the affected cells?
^^^ You can use the open loop table, I just preffer not to & feel better having the PE, RPM & TP based, as opposed to ECT & MAP based, fueling during WOT. Also, the PCM will default to whichever table commands the richest fueling during WOT.

I've left it set up for PE at this point. Pulled the sensors and installed plugs in the bungs today with a conservative tune (tending toward rich B3605). Hope to get it on the wideband and compare commanded vs. actual AFR tomorrow. Car runs great and I should be able to further lean out the tune - improving mileage and performance.
