Yessir. It has a table for target a/f that is based on kpa x rpm. The VE analyze adjusts the VE so that it runs that a/f. Then once you have the VE dialed in, you turn on the o2 correction and it will real time adjust like a factor o2 sensor

Damn, that Megasquirt sounds legit! How much would it cost to upgrade to that? Is there a way to run it together with the factory ecm, or would I have to get the MSD 6010

Hmm, very interesting!! It wires up to the stock coils? Does it support 3bar timing? Too many questions, I'm gonna do some research!

You can make the real time correction and then also have the VE analyzer analyze your entire drive and it will correct the ve for condition you went through. Tuned from idle to cruise to 8# within 3 drives. SOOO awesome. I love it. It's the best thing I've done for my truck.

That thing sound nasty.

Any tips for going from gas to E85 tuning wise?

It's probably not the correct way to do it, but I added 20% to the whole VE table and then started driving and let the auto tune do the rest of the work. Idle cruise was pretty close but in boost it actually cut some fuel from what I added
