Default tunning 8.1 Marine

I'm tiring to get my long fuel trim in to be -4 to +4. I tried adjust the injector voltage to correct my fuel trims but I think I’m doing something wrong so if you guys can help. Here is snap shop of my injector flow, voltage table and log file. Thanks for the help.

I dont think you need to be messing with the voltages. DO you have a wideband on it. Set the IFR to appr values, set up OLSD and fix the Ve using BENS factors is what I did.

im pretty sure your boosted. Get a wideband if you dont have one. Im sure ya know kbracing carries them.

then proceed. Leave the pulse width alone.

IFR should be 43.82 across the board, and i started a thread not too long ago about the voltage offset table. the values i listed have been working great in my truck.

Here is the formal to get your injector size. 43.82 X sqrt(66/58)
43.82 is what the injector flows at 58psi (fuel regular is set at)
My fuel regulator is set at 66psi. Or you can use this excel file.
I had my injector set before at 43.82 and my ve table coming in very high for mods.
