with the temperature get colder but the boost didnt change it is normal to log more load with 1byte ? Like it was 270 afternoon than at night get colder and logging 285-290 with same 26-26.3 psi boost ?

There's nothing wrong with changing the LTFT Mid to high crossover Hz to a lower number. It was meant for a stock car so that the LTFT Mid would be applied to WOT. Since we are mostly over 1600Hz anyway when we start modding, and if you want consistent AFR without the jump in your map, you can change the crossover point.

RC or PTE 1200's
By semi popular demand and request I'm posting some close ballpark numbers
RC/PTE 1200's
Scaling-636-880 e85/91
Volts MS
4.69 4.512
7.03 3.4
9.38 1.6
11.72 1.0
14.06 .744
16.41 .576
18.68 .480
These numbers will get you close and if you enter 1.6 for 9.38v Ecuflash will add the digits out the thousandths automatically.
Please remember each set of injectors are different even from the same brand. If you try these let me know how they work others have reported

Yes and be prepared to make 14v latency higher number as odds are it will jump from +1 to +2 or greater depending on how much more you raise your Global number
Good Luck

I say just stomach the difference, they are just numbers in the AFRMap after all, no real comparison between the 2...just knowing as one goes up, the other will too...

Yes I would getting my real afr's closer to the fuel map afr's . I scaled my injectors how it shoud by the help of fuel trims, they are as close to zero as it coud be. Leans spool up and fuel trims control turn of.
Than I read in the Merlins book page #75 how to get the map afr closer to the wbo2 after injector scaling : On wastegate pressure set the fuel map above load 120 to 11.5 turn of lean spool and log @ wot wbo2 afr, load, and AirflowHz, and where the logged wbo2 afr is different more than 0.2 from the map 11.5 afr there change the maf scaling by logged the Airflow hz with the different in % .
Here is log from 2 car, the wbo2 afr are ok and always the same but exspecially in the Evo 9 the map afr is so far from the wbo2.
EVO 9 PTE 780cc
EVO 8 FIC 1050
