economy tuning
I actually just made the open loop load/throttle tables, and made the change to my high octane map last night, but havent flashed the car yet, because of this reason!
No I dont have a WB nor do I have Tephras knock cell patch.
I understand what youre saying, but it seems like every1 is using the same values / or very near the same values. 15.3-15.7 I even used YOUR cruising area in my HOM, NJ. I figured this should be O.K.

You bought an expensive car and added expensive parts and yet the most important part you did not get.
Tuning w/o an AFR meter is like practicing coitus interruptus, if you pull out a bit too late you can get her pregnant.

mrfred,
I used your xml files, but noticed that the table that allows Evo 9s to control idle is missing. The two tables that are in there do not control idle IIRC. There was a third one that was defined by forum members, but I cannot see it.
This is the code for it:
<table name="Actual Desired Idle RPM" category="Idle" address="3d24" type="2D" scaling="RPM8">
<table name="Engine Temp" address="70c2" type="Y Axis" elements="8" scaling="Temp"/>
</table>

It is your car and your choice. I will not take this risk with my car. Each Evo is different and they react differently to this mod. On some cars this mod did not work, on others it did.

OK I will NOT flash the car w/ the new mods!
I had a little snafu coming home from the shop today.
Went WOT at my favorite tunnel and my car felt weird, kinda fell on its face. I look at the AFR and it's still 15.4 AFR at WOT! Which is the same AFR I cruise at now.
First thought was that the FPR hose popped off, checked that, nope. Looked over the engine bay quickly and saw nothing out of the order.
I am hoping it's something else that failed/failing (like my fuel pump or something) and nothing to do with the lean cruise stuff...
I'll have some time tomorrow to look stuff over.
Thank god for visual AFR gauges.

I had this happen to me, but it was the FPR hose that popped out. The AFR gauge was very helpful when this happned. I have since zip tied that sucker really hard.
I hope it is nothing serious.
Ok the problem was the fuel pump that went bad. Popped a new one in today and everything is fine again.
The pump lasted around 44,000 miles and eleventy billion track events.
29psi and 15.1 AFR ftw!

To be honest I'm surprised it last this long.
My car has been through alot of constant abuse and R&D work.
I've been at 110F track events that make the fuel pump whine so loud because of heat I can't hear my exhaust over the whine when I come back into the pits after 20 mins of constant WOT.
44k miles on it, probably 20-30 track events, some car bowling, i'm sure over 500 dyno pulls and simulated road tuning on the dyno.
29-32psi. I've run the injectors at 100% IDC a bunch of times.
The car has led a hard, but fun life so far.
Even without a AFR gauge I would have stepped out of it as the car just felt like ****. Although I can imagine 29psi at 15 AFR would feel a tad different than 22psi at 15 AFR. Without the gauge it probably would have taken longer for me to figure out what was wrong though.
