Its seeming like its going to work, which is exciting. I'll be testing further

I was able to get it to function, I checked out the F150 tune and saw that the table was defined as shown below: It looks like it cannot handle values over 1. This explains my issue before, because I believe my table that caused rich running (shown below) was setting the internal value to 10, which the computer interpreted as 10000% and slammed the mixture to the maximum of 9:1 and caused the rich running.

I've got nothing but time right now There are 73 tables to be precise, I made this handy little spreadsheet for anyone who wants to do something similar: F150 Flex tables, ECM to AuF.xlsx Green highlights are what I felt were critical tables. I think I'll start from scratch, something is missing from my tune. Which I also forgot to attach: 05_CustomOS_flex_basic_CustomOS.tec If you guys have seen it work then I definitely want to see if I can replicate it.

I was actually able to give this a try. The file is attached if anyone is interested, unfortunately I wasn't able to get it to behave correctly. If I calibrated AuF29291 as you guys did, the ford ethanol percentage would track with the CuOS ethanol percentage measured off the sensor. However the car would idle at .7 lambda, absurdly rich it was targeting 9:1 AFR it seems. Barely started. I then assumed the table was swapped and tried the following: This allowed the car to idle at 1 lambda again, but the two ethanol percentages no longer matched. I tried various combinations but found that unless the top percentage was mapped to 0% the mixture would be off at idle. I also tried using .1 and .85 instead of 10 and 85 but found no change with that. Heres a picture of the car idling on e10 gasoline at 9.7:1 AFR lol. This is a real 9.8:1 because the lambda reading in the datalogger was .7. I also tried swapping all of the flex tables including the can flex tables. I know you guys said it works so I assume I dont have it set up quite right. Either way I wanted to report my findings, I figure the more data you have on this the better!

Understood! I'm willing to beta test then. Just to confirm, you guys are looking to test this functionality in the PCMTech DIY software package? Or the full Workshop package? Just want to double triple check everything so there's no confusion😅

Actually I'm looking through the install and I wont likely do it exactly as written. So I think I can't help create the writeup you guys need. I ran CAN, power and signal wires to my trunk for a previous install that has since been de-activated. I will be reusing all that and will be mounting the analyzer-CAN bridge back there to save headache from re-wiring. My install will not be typical, so I will back out. If you guys need someone to test out the functionality of the software I can absolutely do that, but my writeup would be very atypical and not useful as instructions for others. Apologize for any confusion!

I can pull it off, the install looks straightforward enough. Mostly wiring it seems. I know mike and k44 have been more active and involved in this, so if you only need one or two testers then I have no issues letting the opportunity pass and waiting for a final release.

I know I haven't been as vocal on this but if you need more testers I volunteer as well

Thanks for this reply, can't wait to try this out! Once my dongle finally arrives lol
