when I tap the throttle from idle, and I mean *barely*, the BLM changes to 134. I can give it any amount of part throttle and it will be 134.

I was looking around and it seems AE starts at 1.57% TPS, and thats right when it does it

when I'm driving at part throttle it stays at 134 also.

which table controls this?

I adjusted BPC vs EGR from 85 to 90, then to 93 and no change

changed the AE Async Pulse Multiplier vs Delta TPS all the way up to 1.99 (highest it goes)

and upped the AE FACTOR % BPINJ by 25%

still when I barely tap the throttle BLM goes to 131, actually its even higher now at 134.

I disconnected the battery and all too..

This is why I like tuning with a high speed WB02 rather than going by what the ECM is thinking is happening. Especially on a speed density system like ours.

134 is not far off and honestly if you are not feeling a heavy lean bog I would leave it alone. It is great that you are trying to fine tune...but if the driveability is clean leave it alone. Just my $.02  ;)

I just dont understand because it was ok before, I had it at 125-127 just a couple weeks ago

thing that concerns me mostly is the lean BLM will overrichen WOT

I have WBO2 in that datalog

Don't never trust a stock o2.They are only designed to be accurate between 400-600mv and they are not all that good at it.Have you disabled closed loop?Open loop is the only way to fly with a wide band.Don't half to worry about your dumb azz computer making misinformed decisions and taking forever to make them.Sounds to me like your having tip in issues.Some of the things you tried should have helped,fixed or at least made a difference.Does your wide band say your rich or lean?Find that place in the ve table(rpm and map)and add or remove fuel to see what happens.Also temperature changes will affect you blm a lot.I usually play with the injector flow rate to get things back in line.You also have MAT tables that add or remove fuel by temperature.You only mess with this table if your running a different top end or if you have relocated your MAT sensor.I think thats an inverse table but I'm not sure.Hope this helps...Adam
