What's optimal for these things WOT?

Tuning the Focus ST (my last car I tuned) I aimed for 11.5-11.8

 

around 12.8 is what i aim for WOT.

 

I've tuned multiple cars, including some SRT4's, as well as my big turbo Focus ST, which was my last forced induction car.

 

granted that N/A american V8.

 

Damn, on a 2.7?

Seems rather rich.

 

Yeah, I didn't pay attention in Physics.

 

its the perfect air fuel mix (in theory)

 

Think you can help me tune the AEM FIC when the time comes?

 

Under acceleration, it dips down to 12. Sometimes it says LEAN. It says Lean a lot when I push it.

 

if i remember right 12.1 is typically the most "performance" you can get WOT

 

LEAN is bad. lean burns things up. lean makes things hot.. running a little fat is kinda of a safety net.

 

wide open turtle. performance talk my friend, you wouldnt understand

 

I can definitely offer as much advice as I can (basics).

My tuning was learned awhile back with the SRT4 swap; did a ton of datalogging while doing 3rd gear pulls. Fortunately, never blew anything up lol

In your case, it's safer since you've got a baseline.

I had to go bigger injectors (527cc to 577cc IIRC) and it didn't help that I kept adding bolt ons that would later affect my last tune

 

I don't even know where to start. I ordered the piggyback harness so I don't have to chop up the stock one, and then I ordered the AEM FIC module. That's as far as I know what to do.

As long as your truck is maintained, and as I mentioned, you've got colder plugs, you're off to a good start.

I don't know what failsafe you have or will have in place for when you run out of juice, but you'll definitely want to pick up the tuning and get it dialed while off meth.

 

INB4 blown 3rz

 

So I should tune it before I install the meth?

 

Best thing to do is, set up your laptop (I used to use a netbook), and do 2 runs in one gear and datalog.

Wait awhile, let the truck cool down, then go do 2 more runs in that same gear and datalog.

From there, we can see if you've got pinging, what your AFR is at, if you're pulling timing, etc.
