Default MSQ and datalog review

Hey all, I have my 90 with the BEGI S2 and I am in the beginnings of learning to tune it...ever so slowly. Gotpsi has been helping me and all the credit to the fact that it even started goes to him.

But he is on vacation, and I am sure his wife is sick of me, so would anyone mind reviewing these two files and offer up some advice on fueling and why I might have a huge new idle bounce now that I used mega tune with the last data log?

Thanks all.

Oh and thanks to Perez for showing me how to post these.

I noticed that your CLT signal looks just like mine, are those spikes normal?

I'm pretty new to this myself but I think I can point out a few trouble areas. Number one is that your AFR table in your MSQ is ******* nuts. Change that to one of the many more reasonable ones floating around here. You're way too lean in boost. I'd change the out of boost as well but at least that's not dangerous. Is that what you're using to tune with in MLV? You also have EGO turned on under the exhaust gas settings but you don't have the AFR table turned on under the Lamda AFR settings. That's fine if you're not planning on using EGO. Just thought I'd point that out in case you wanted to use it. You're Idle does not seem that lumpy to me. I'm no expert in idle control so I'm not going to comment further on that. Your VE table is kind of all over the place. You seem basically mega rich everywhere with some lean spikes. Find a GOOD AFR table plug that **** into MLV go drive for 20 minutes or more. Use the VE analyzer set on Easy and keep doing that till the numbers get closer to something sane.

idle is probably due to the 147% Gair enrichments.
