For starters I have been a member of HP Tuners for many years and gained a tremendous amount of tuning knowledge form all you seasoned tuners, for this I thank you all!
I tune using lambda with my wideband. My process is to pull 4 or so degrees of timing from my low octane tables and copy this into my high octane table, add a percentage of fuel across the ve table depending on engine modifications made and then tune to stoich. Now I have read that one should leave PE enabled during this process but this doesn't make sense to me because then I would be leaning away the PE commanded richness that is later needed for safe power generation when your foots down.. So I disable it and complete my stoich tuning and when done with VE and Maf tuning I re-enable PE which is then commanded on top of my new stoich. Then of course I move back my timing tables. Please straighten me out if I need it!!
