$6E need calc bpw checked?
Dumb question. I know from a $32b I had to uncheck the calc bpw so I could use the tables. But I have since upgraded to $6e. Night and day much better!
I figure sinec there are no PW tables like $32b I am just using the maf table and AE/PE adders. My Calc BPW field I have checked. meaning it doesnt use tables. This is the original setting I left alone for last 50 tunes and it seems to work and I see progress in my tunes.
So does this do anything for $6E?

Re: $6E need calc bpw checked?
This might be another dumb question, but did you get your "base tune," part throttle no AE PE HWY modes by playing with your MAF tables alone? I am having a difficult time making sense of everything in terms of fine tuning to get the fuel trim where it should be, mine likes to be rich when not under a load and lean as soon as you put the engine under a load. The MAF tables confuse me because my car goes rich/lean based upon load? Still trying to learn and experiment.

Re: $6E need calc bpw checked?
Rob Thanks. That is what I figured.
86Frank:
I had similiar results of rich/lean with $32b and improved once I went $6E and full tune up and repair vac leaks.
couple tips:
1: if your not idleing well then you should fix that first before any tune. No sruges or runaway. Mine still idles hi and little lean in open loop but drops down and in closed loop is little rich when cooler
2: After all my tweaks to multiple tables I found that Inj constant and inj pw vs battery are first 2 tables that effect everything the most. My goal here was to see was to adjust where blm were 128 or typically below in 120 range for idle cruise conditions for my and was 128-130 for AE/PW but then I started to play with maf
3: Cruise: Then I adjusted the Maf #1 and 2. lv8 from 0-50 is idle and cruse for me and around 7-9 MAF g/s I can now tweak these in 0.2 increments and can easily swing my cruise BLM from rich to lean. This is typically good up to 1400 RPM range then AE/PW kicks in. The Battery and Inj Constant tables have huge impact on the idle BLM.All of this for me was done at closed loop. My open loop I have not touched much. So I know I am lean there
4: AE: Between 1400-2000 other then WOT stabs it seems AE has huge impact here. I usually look at my BLM ranges by rpm by MAF in tuner pro to see what needs adjustment. You might need to play with tables 2-4 to get those initial BLM donw. Mine were typically in 129-130 range. But for most impactI found that AE pulse vs %bpw has biggest impact to the feel of the AE launch and pedal feel. First 3 pules I have maxed out at 3.98 if I max out 4 I can actually go rich and bog and if I go low on #3 it goes lean so play with those too to see movement. But I still ran lean in these areas but with good pedal feel only until I increased my Scaler AE max pw from 5.55 to 7. This made uge differance I tweaked it up until it seemed to not make a difference. Then I went back to the AE bpw table. after that the %AE factor vs lv8 that makes another impact.
5: the PE I use the PE vs RPM. I found smaller tweaks in 1% range or less makes difference. I see 128 but this is hard to tune without WB
