AFR for WOT on a stock GTP?

[Bedwards]

Anyone know the AFR while WOT on a stock GTP? It must be extremely rich... Because after installing a VS cam, I started with a GTP MAF table and it's running 10.7. How can it be so rich with a cam? Seems crazy to me.

LTFT at WOT still 0?

Also you're probably well outflowing a stock GTP so you're probably at parts of the MAF table that are normally never reached by a stock GTP.

aim for 11.2-11.6

The stock AFR in a GTP begins in the mid 12's and starts dropping over time if I remember correctly. The VS cam or any cam for that matter requires that you tune your MAF table.

LTFT is 0. I'm hitting 10.7 AFR from 7000 hz on. It's not a big deal, I can tune it. I was just curious.

I know I have to tune it lol. I've been tuning for a while. I'm just confused why I had to pull fuel at WOT with the addition of a bigger cam. Thought that was odd.

I see, so you're talking about commanded AFR, or are you using a windeband?

I use a wideband. I did another scan this afternoon and noticed the AFR mid-11's, which is what I want. Maybe the 10.7 was outside air temperature related, not sure... It's hitting this AFR with ZERO tuning on a stock MAF table, from 7000 hz and up. I've obviously tuned my cruise settings, but my WOT fueling is fine as stock. Crazy.

Not crazy.... I have been trying to tell people this for years.
