Why is my PE adder table look like this? Why does my tuner have my PE adder vs. Coolant temp look like this?This is my AFR table the 0.00's are from 140-212 degrees....
0.391 0.349 0.309 0.269 0.227 0.186 0.144 0.106 0.064 0.023 0 0 0 0 0 0.047 0.094 0.094 0.094

exact as a matter of fact
140-212 is normal operating temp... looks like at values outside this range it adds more fuel ... the main one you should be concerned with is the PE vs RPM as that is the primary table used in PE mode

I guess it's doing cold enrichment for drivability
(cold just likes richer) and adding a little hot to
fight ping. About the "normal" operating region
it figures the main PE table is representing.

That's way thinner than I use and I have my MAF
table nudged rich too. I am 1.14-1.15 on a rising
rate. You have a fat bulge in the middle and it
rolls on awfully abruptly. What's with that dip to
1.077? If I had that table I would be pinging like
mad. I think you want some wideband data.

my PE vs RPM looks like
1.183 1.183 1.183 1.186 1.186 1.186 1.186 1.186 1.131 1.131 1.131 1.131 1.131 1.131 1.131 1.131 1.131 1.131 1.131
but mine's a scaled stock table... yours appears to be a custom table...
My IFR table is also scaled by 165% since i'm running larger injectors (using the formulas out their I'm supposed to be like 195% but that was making me WAY too lean)
for setting your PE vs RPM table you're best off doing wot runs and watching your O2s (well you're best using a wideband, but if you don't have a wideband, then narrowband o2s will work) .. shoot for 930s to be safe... then lean out a little at a time... i wouldn't go below 910s
IFR tables are kinda setup and car specific though.... don't just copy and past a table in there... actually tune/dial it in....

MY AFR is 12.8 or 12.6 I cant remember?I have an X1 cam,MTI s2 Heads,1 7/8 Kooks Headers,Fast 90 mm intake ,TPIS 90 mm tb,Bigger MAF composit MAF ends,and 2001 28# injectors ,I no longer have the 26's that came on the 99's.right now I am at .900-.910 mv's at wot and I do get up to 2.5 degrees of KR and sometimes 3 degree's,Hmmm to lean you think?

I think you should log and plot your O2 voltages
vs RPM, and your Fuel Air Multiplier vs RPM, and
see what these look like - visually, it will show
you whether there are any funny ups & downs
or a well behaved enrichment (actual and intended).
