Has anybody had a chance to try this bin yet?

unlikely

if any of you mach members want to become premium members it'll force me to do it til then Its on my to do list when free time permits which isn't very often at all

Decipha i would love to be fly on the wall while you go through the tuning process on some these cars. I bet that would very fascinating to watch. And very informative!

Alright im back to tuning on my Mach, or at least getting to start once i get time. I have a few questions regarding the factory bin. The first question is about the timing table. Its commanding 50 degrees at low loads in the cruising area of the table. Is this normal? Second is the K-Constant is set to 24.265. Should this be changed to 30 and then the rest of the injector data be updated? Third i understand how to dial in the bottom part of the curve using fuel trims but can WOT be dialed in using fuel trims or should drill and weld a bung in for my wideband?

It'll run fine but I would set k-constant to 30 and then re-enter your injector data from the reference page. That way your tune will scale if you make changes later.

You can't tune WOT fuel with HEGOs you'll need the wideband on one bank at least

I just reread the fuel write-up. I shouldve done that before posting! I guess i will be putting the wideband back in this weekend. In the meantime im going to use KAMS to dial in the lower half of the curve. Thanks for the reply.
