using 14.047 for desired AFR and not 14.63?

Correct.

Picnic_George, not trying to be difficult but it helps if you post up any tune you are referring to.

I realize that, I'm not trying to be difficult either. But I'm on a different computer :P I'll check that out and get back.

B4206 was enabled, I'll check that out later tonight and hopefully get this going. Thanks guys..

That helped considerably, there was a lot I had to do on the low load/rpm tables. Up top not much changed from where I had it but I kind of expected that anyways. I'll log a couple more sessions, clean my MAF and make sure that is in check.

Maybe I don't see it. I don't see any peaks or dips in it. I didn't smooth it but it looked OK. The car always ran well.

Does this look better?

Yes.

Why is the ve table so low in the low load and rpm ranges? It seems like it is much lower than even a stock engine. Is it to do with the cam?

What mods are done to it? Post another log if you can. Do anyone know what the specs of a stock LS1 cam are?

I also think you are way lean in PE mode. Would it be safer to set B3618 richer than your B3605? B3605 is ect vs map. Maybe run a cos with B3647 with map x rpm if you want to stay open loop.

PE is disabled on this tune. Running strictly off the VE table. Now I gotta dial in the maf. I just gotta remember how. I think I leave everything exactly the same just turn the maf on and set b0120(i think) to 400 rpms?
