So i was going through some more settings in turner pro when i came across INT Rich and lean values VS' Map, with the simulated NB output from the WB the Lean and Rich Points wont change with engine load any more so all these should be the same. Am i corect on this?

Also INT Delay Mult vs O2 error should all these be the same as well?

 

You shouldn't need to change the rich/lean/mean O2 switching tables. Although they may be changed a bit for different results. From what I've been able to tell GM set them up to match the type of cat-con that was equip'd on teh vehicles: 2-way vs 3-way.

There is more informaiton on how this works on the DIY_PROM board, sticky's, Tuning Guide Book, Chap. 5, '8063/'8746/'7747 ECM, Fueling Logic.
