Wideband AFR and Fuel Maps are way off.
My fuel maps get to 10.6 at redline, but the wideband reads upto 10.0(which is the least the gauge can read)
At idle, in the map its all 14.7s and the gauge reads 14.5-14.6 which I feel is okay.
Is there a way I can get them to match at redline or atleast be close?
Or should I keep on leaning the map till I achieve figures of around 10.6 on the wideband?
NOTE: Our country has ****ty 89OCT fuel which means I shouldnt go very lean.

The numbers in your fuel map do not represent what you see on your wideband gauge. They are simply numbers. If you are seeing 10.0 on your wideband, then you should raise the number in the fuel map that represent that load/rpm cells until you reach the desired AFR you are targeting (11.2-11.8). You should consider getting it tuned by a reputable e-tuner on the forum.

It's possible to get the pretty close by adjusting MAF scaling if I remember correctly?
That said, I don't think many people even bother.

Yup normal. Even on a bone stock car the map values will not math actual AFR ever. I've heard folks mess with scaling and such to get closer but all in all they are just numbers adjust accordingly until you reach your target afr on you WBO2. Let me guess Fab Five Freddy said they are supposed to match huh??... Dude is useless

Oh no everyone tuned with ecuflash your car is a ticking time bomb!!! HAHAHAHA
Get a clue Right said fred or I know maybe even SEARCH Map not matching actual AFR. The topic has been covered multiple times you'll find comments and information from the guys that tune these cars everyday. Guys that have set records, guys, myself included that have used ecuflash SFTW since it inception and have 100k miles of flawless operation, one guy has damn near over 400,000 miles on his car at this time. I believe his last post showed 440,000 miles. On his Instagram.
But youre right and everyone ele is wrong right? Please stop spreading incorrect information you know nothing about in the tuning forums. Thanks

You shouldn't go too lean with junk fuel, but try to at least get it in the mid 10's. Run less and less timing if you have too.
