Open Loop Tuning Is Not Easy

Open Loop Tuning Is Not Easy I pulled this quote from another thread: I've been running OLMAF for several months now with my LM1 in the car and adjusting the OL AFR and MAF tables. I've gotten it within an acceptable range, but I do notice that the AFR varies somewhat due to conditions.
Can anyone comment on the parameters for tuning the filters and bias Ed mentions in order to get AFR more consistent?
Open loop tuning is NOT easy, it is more difficult because you don't have that automatic correction so after dialing in the VE and/or MAF there's OL vs ECT to get right so A/F stays somewhat consistent, and of course there's IAT filters, charge temp bias, etc. to get straight so your A/F doesn't end up creeping from IAT heatsoak. No, open loop tuning is not easy.
