Does my a/f seem right? Finally got my lc-1 installed the other day, and been checking out my a/f.
At crusting speeds it reads anywhere from 13.9-15.2
And when I get on it, it reads 13.4-13.8
When decelerating it'll go to 16-18 but that seems normal.
What you guys think? To lean, to rich? Almost dead on?
Sorry if anything is wrong I'm doing this on my phone.
Ok, got a new MAF and it runs 11.9 @ WOT and 14.0-15.0 at cruise.

You're part throttle needs a lot of work, too much swing. Mine is between 14.4 and 14.8 most of the time with some bigger spikes every once in a while.
Full throttle should be about 12.6-12.9 if you're naturally aspirated, 11.5-11.7 if boosted. What you have now is dangerously lean and I would not get on it at all until you have this fixed. That lean you could do some serious damage at full throttle.
Where is the sensor installed? If it is far enough from the headers it might read lean from what I hear.
My idle and cruise sits at 14.8-15.2 and the way EFI live does it's auto tune it always puts WOT at 13.1-13.4, but I adjust it to get it at 12.6-12.8
Was the car tuned? By whom?

if your WOT is about 12.5-12.9 and cruising is 14.2 most of the time then I would say its doing ok, I don't like it if its leaning out at part throttle to 15+ most of the time...stoich is 14.6 for cruising you want to be there or below just a tad bit.
I would take it somewhere to have it checked and tuned. THose mods you have need an adjustment in the tune.
