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.

Re: Hego amplitude, and bias explained, A9L2 compatibility
yeah you have to be careful with caledit as its known to corrupt things
if the o2's are yanking that much fuel then you have to dial in fuel first before you can worry about tip in
No, the amplitude is not the us_sw which is the switch point voltage. Amplitude is how much is makes lambse jump when the o2 switches.
bias is another factor as that is how fast or slow it ramps back lambse's until it switches
Yeah you have to use the a9l2 with tunerpro otherwise some values are going to be jacked up when viewing in BE since there is no correct strategy file for BE with it.
Best bet is to make all of your base changes with tunerpro then after you have all the important stuff dialed in you can load it in to BE with the GUFB xls and make simple changes. You can also verify by opening the tune back up with tunerpro and comparing it to the older version of your file to see that your changes are correct.
Remember to never change any value that doesn't look correct as it will corrupt the file.
I just posted a newer updated A9L2 yesterday I'd recommend starting from that.

Re: Hego amplitude, and bias explained, A9L2 compatibility
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.

Re: Hego amplitude, and bias explained, A9L2 compatibility
The breakpoint is the fuel mass where it changes slopes so thing of it as the amount of fuel the ecu is asking for in lbs.
if you have the frpp 47s just load their data in and dial in the maf.

Re: Hego amplitude, and bias explained, A9L2 compatibility
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

Re: Hego amplitude, and bias explained, A9L2 compatibility
no you can't adjust the slopes if you did then you wouldn't have their data.
Put in the actual injector data and dial in the maf.
Injector data is on the homepage. http://www.efidynotuning.com/injdata.htm

Re: Hego amplitude, and bias explained, A9L2 compatibility
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.

Re: Hego amplitude, and bias explained, A9L2 compatibility
You cant just change PRLDSW without changing your commanded fuel to match.
Info is in the fuel write up
