anybody have any ideas hit me up. cant log any fuel trims. they just stay @ zero. never move. replaced front o2 sensor and rear o2 sensor is not deleted. checked all fuses. anybody have any ideas. cant scale in my injectors

 

are you tuning it yourself now? maf ? sd? if sd.. i dont even use fuel trims half the time.. the name of the game is to keep AFR's at or around 14.7 on cruising/driving conditions .. that = smooth sailing.. no lean spike jitter, none of that garbage. (open loop)

airflow hz can effect trim crossover - you adjust that via lt trim control tables.. prob need to add it to your xml though.

global scaling is in direct correlation with fuel map values / as is maf tables, so even if theres no o2 feedback on a car u will know whats right & whats wrong.

 

no not tuning it myself. havent got 4 bar yet. just trying to get it a little better. also the maf translator was bad. put stock maf on and idled like butter. just dont know why i cant log trims. just seemed odd they never move.

how would u scale injectors if fuel trim no worky?

 

tell me what size injectors and what fuel you're using and ill post some scaling & latency for you.
