Im tuning the 4288 and A0 mask with the Barl code for an s10 4.3l. This seems unusual to me, but everywhere i read on here they say to tune o/l i need to adjust the cool. min. for c/l high, but when i do that the blm's and int's are always locked at 128 and dont show up in winaldl. Does anyone know why, is it just part of the code itself. any help would be apreciated. Thanks Kyle

edit.. i also made sure the max and min blms are 108 and 160 respectively

 

The guys that are doing open loop tuning are typically using a Wideband and have closed loop disabled. Forcing the coolant temp setting for closed loop very high in the constants will disable the fuel trims and lock the INT/BLM @ 128 on ECM reset(happens when you power down the older TBI ECMs(Turning off the Ignition) ).

 

So what your saying is i have to use my wb to update my ve tables, i guess thats cool but is there a certain calculation i can use to convert my wb voltage or lambda or afr to the delta change needed in the ve tables. I found a formula searching through the form about changing the ve based on the int's and blms. and i put that is a spreadsheet. Is there a formula for doing it with o2 voltages or lambda and afr? Thanks Kyle
