Help tuning with edit on a dyno Guys,
Would like to have some help with tuning on a dynojet 248. Recently bought this equipment with a wideband and now I need to learn how use it to help tune. Have ls1 edit, tech II, and wideband for the dyno, also the dyno has the load control option. Have been spending alot of time searching this and other forums to learn edit, but I would sure like someone to share what processes they use to do a tune with edit. Have a couple of cars in my sig. that could use some tuning! Have noticed some with a wealth of knowledge on this forum

I don't get it, that sight tells you to adjust the MAF to get -trims. However, when you tell people who do ls1 edit that you adjusted your MAF they tell you OH DON'T ADJUST YOUR MAF! what gives?

What I would like to know is where do they start? Can you calculate what values should be in the VE table based on mods done to the car (sounds like what is being talked about on the pinned post by NoGo)? I recently purchased a mail order tune from a very respectable LS1 engine builder for my 427 z06, only change to the VE table was a 25% reduction from 400-1200 through all load ranges. I think it can get much closer on the tuning. The car surges at idle and ltft are 3-10% positive. One tuner told me he has never spent more than 2 and 1/2 hours tunning a car on the dyno, so that tells me that he is not using ltfts because he wouldnt have time to let the pcm learn and try to make changes based on that. What I suspect that they use the wide band through different trim cells and from that make changes with edit to dial in all the cells.
