so when setting up fueling should I change PRLDSW to 1 so load scaling does not effect LAMBSE, and it is strictly going off tables while I am matching maf curve to wideband output, then change back to PRLDSW=0 to then adjust FN035 to get correct load scaling?? I have the actual injector data from datasheet entered.

So, I did load their data, I am assuming what I have to do next is get my widebands hooked up, and make the WB match the LAMBSE while @ WOT?? I am assuming I would make them match by adjusting my slopes accordingly. I got the 30pt function sheet with my MAF from PRO-M, not sure which of the two to mess with?? The Vallues I have entered is : 1.3068 bkpt 46.8195 High slope, 51.5900 Low slope

Offsets are
15.9375 0.7188
15.0000 0.7188
14.0000 0.8125
13.0000 0.9063
12.0000 1.0625
11.0000 1.2500
10.0000 1.4688
8.0000 2.2500
7.0000 4.0000
6.0000 6.5938
5.5000 6.5938
0.0000 6.5938

I'm not sure what I'm doing wrong

I had heard that caledit has a way of boogering things up, so I started from fresh with Binary editor. Don't jave access to wideband data at the moment, but fuel trims seem to hover right around 1 all the time. Another topic I saw in your fueling writeup, which was super helpful, was the breakpoint setting. I have started with what the ford spec sheet called for, but you mentioned I may need to move that around. I know it separates the low slope from high slope, but is it doing that based on rpm, load? I guess I don't understand exactly what I would be changing by messing with it. Sorry if I am going over things I'm sure you've explained a thousand times.

I have Binary editor, and a Tweecer, recently got BE, changing over from Caledit, man what a difference!! Things seem to be going along pretty well with the exception of light cruise, closed loop keeps comanding (LAMBSE) AFR into the 17-18:1 area and i'm getting Lean pop with a bit of tip in. When I roll into the throttle, the car briefly feels flat, then it "catches" and starts pulling. I imagine this is in my transient fuel/closed loop setting and giving me fits.

My understanding of Hego amplitude is it basically tells the hego when to switch, right now, the numbers are pretty much stock at .4861, I am assuming this means that when the hego reaches ..4861 volts it switches lean and when it reaches .0621 (.4861-.420) it will switch rich?? I am having a hard time figuring out what exactly this function does.

Please explain Hego bias in laymens terms, again having a hard time wrapping my head around it.

Can I use/flash the A9L2 strategy, and use it with Binary Editor, or is Tunerpro a must?? Not familiar at all with Tuner pro. Thank you so much for your help, and Decipha, thank you for your wonderful write ups, it has helped a good bit.
