question about AFR
Hello
have been having some trouble with the AFR freezing at 10.4 and the AFR trim % stays at 0.0 and wont change. the truck will run good after I load the v8 tune and will run good for a day or 2 and then the AFR goes to 10.4 and AFR trim at 0.0 %, I have checked all of the wiring and it looks good. I have read on the forum that other people have had the AFR freeze at 14.7 and not change and then comes back after reloading the tune to the ECU. this has been happening to me for a couple of weeks now. If needed I can upload a file log when it happens again or if you need a log at idle warmed up first, it just seems to lose something in the tune for the AFR to freeze.
Thanks again for any help

Is the MAP changing or is it static too. Sounds similar to the issue I had. Turned out to be a bad MAP sensor. Had to return and get replaced. The MAP sensor it only replaceable with the ECU. Working good now.
thanks for the reply will check MAP sensor the next time it happens
Thanks

just an update reloaded software as per Bryce from fitech and has fixed my problem with the AFR the unit has been working flawlessly for the past 10 days and is just getting better as it learns, looks like the software was corrupt. Thanks to all for all the info I have found on this site it has really helped with troubleshooting and a special thanks to Austin for all he does with the website and the answers to every bodies questions
