Default Tune OL SD to be a lean cruise sort of??

could I just tune the car with wideband to get the VE right...
and use the OL Ratio table to make it a lean cruise mode???
and disable LTFT...
or is there a better spot for me to make it happen so that its like having OL SD lean cruise all the time??
what table is the best one to modify to be like the lean cruise table??

sounds like a reasonable idea to me... IIRC though, the OL table is ECT/MAP. That may be a hurdle to get over.

Just out of curiosity, why would you want that table set to command a 14.8AFR?

Pe will take care of any richer mixtures just make sure you set the delay RPM from 5500 to 0. Even before i set it to 0 i seen no issues . If you are really curious check out an 03 silverado bin or an 05 CTS-v bin

so obviously If I put the whole table to 1.0.....it wouldnt hurt ANYTHING..lol

I just want to know the best table to use to command my fake out lean cruise...
obviously I'm going to tune VE to be dead on at 14.63:1 by using the wideband commanded AFR error % tuning at 13:1 and changing the table back to all 1's later...
