Hello.
It was found that I had setup a semi open loop and I believe I made all the right changes to bring it into full open loop speed density.
For some reason when I decelerate or even just let my foot off the gas I go rich. I give it throttle and I see stoich again.
I started to adjust the main ve table but then noticed it takes fuels out of the deceleration cells constantly till I am almost at 0 in those cells and it still stays rich no matter how much I adjust them.
I started to back link the scan tool cells to see what it is using and I see in the spark etc table it s using only the 140c row of data to adjust the dyncyl air. I had my temp in F and changed it to C thinking this could be the reason that cell tracks only in the 140C row only but that didnt change it, The engine runs in 90C constantly
I see the same thing happening in coolant temp spark multiplier using same 140C row only. My intake air temp is in C also and same thing with spark iat table.
I am now looking at the B3647 and I see it is only using mostly one column in the 20kpa... What am I doing wrong and is this the reason for the decel fuel to continuously take out fuel?
Thanks
Louis
