Hey everyone!
I'm looking for input on the best fuel controller for the Z. I am NOT a fan of cutting into harnesses and scotch locks made me crazy!
I'm running very lean currently, tan ground electrode and white insulator… so I need to act fast!
Thanks,
---Mike
funny you say your running lean
im used to cardboard color on the porcelain and slight color on the metal
here is mine with exhaust, intake and bazzaz with mnnthbx tune
and plug has decent amount of miles on it, enough to show any color
now I feared I was lean, until I connected my wideband and actually found at least on the top end, (which is most important to me) I was around 12.3 I think which is still on the richer side since you can go to over 13 and still be fine and of course super rich would be in the 10's
I will admit in the past when I only went off color, then later when I got my wideband and retested they were pretty rich
much richer then I had thought
so maybe going off color only, and just having a touch of color is good enough
of course my plug in the photo had no color at all
in a few months I will check back see if any shows up
unless I big bore I don't think I will be doing anymore mods that require new tuning
