Switched from regular maps to big maps now afr opposite

[bw2277]

So I been driving the car with stock ceddy mod maps and running normal, I got the big maps version but when I flashed it to ecu I am running like full rich on the wide band when iding, and go lean when it starts to hit boost. Am I supposed to switch something in the bits? Any insight would help being im still pretty new to ecu flash. Thx

Big maps will require you to sit with it and work out a tune. In its "stock" from it will run richer than factory. I also have big maps but I haven't say down with it yet to come up with something. So I switched back to the maps I had already did a tune on for now till I figure something out.

I had to do the same thing and switch back to normal maps, I thought they were the same but nope so back to figuring out a tune. Thx for the help
