you can tune anything, just hook up the lap top when the car is warming up, and look at which cells the car is running at (rpm/vac)
and then lean those out a few points
and then lean those out a few points
got it. afr is in the high 13s warming up now. i tried to make it a bit leaner but the car would stall out
With my 440s the stock ecu is capable of pulling just enough fuel to keep the afr just right by itself. The short term fuel trims are almost maxed out at around -20-25% (ecu range is +/- 25%), though. So with the the 565s I'm assuming that the ecu will not be able to cope by itself.
From personal experience, one has to make the change to the closed loop AFC table in a very fine and gradual manner; small to bigger from idle to open loop switch over point. Starting at idle, you should pull fuel by only .1 or .2 points and gradually pull more towards whatever you have the open loop switch point set at (default of 1.1 psi)

I thing I'm using a modified version of your 440 map.
Running good but idle is lean. Like 17-18. I just changed the coils, wires, plugs, injectors-to 440s, not sure what else to look at.
What are the AFC map values at 500 rpm cells?
id have to take a look.

Well, what I recommend is to let the ECU control the 440s in closed loop by leaving all of those cells unmodified with a value of 10. It does a great job with them after a few days of learning.
I've switched to a NA ecu since then and think that I've created a very smooth and clean 440cc map for it. Once I work out an "inconsistency" problem the map will be posted here for all to try.

Nice.
The settings are @10
Was this issue present before you changed your plugs/wires/and the injectors?

My car is idling very lean as well. I just bought a new revised EGR valve so hopefully it works.

I have a grounding kit. I'll try and clean and test the o2 sensors. Thanks.
Pm me if you have any more ideas.
how do you test the O2 sensor!! ive been searching and cant find anything
A USB OBDII diagnostics scanner would be a very good investment if you can afford one. It'll tell you everything that you need to know about all of the sensors. One can be had for about $60 these days. Pair it with the PCMSCAN software and you have a very powerful diagnostics tool.
If I were to run a map with all 10s should I expect the car to run like there was no afc installed or is it still going to have some influence? I'm trying to figure out if my unit is working correctly and thought this might be easier than actually uninstalling it. Any input?

all 10s should effectively cause it to be inactive, assuming it is operating correctly.
