Quick question With the Aeroforce gauge....while reading the LTFT when the number is positive does that mean it is adding fuel meaning ur running lean and a negative number taking fuel away meaning you are running rich??

Someone explain please THANKS

 

When the number is - it means the computer is taking fuel out.when it is + it is adding fuel
I wouldn't worry about it too much if it is - a bit (-4). You don't want it in the + because when it goes into pe mode it won't go as rich as commanded.Anything close to 0 is ok.
right now mine is running -12 at idle cause of the 60lb injectors.I still have to tweek the maf table. if poss I am still trying to figure this whole thing out.

 

may be a dumb question but what is the difference with the short trim reading and the long trim reading on the aeroforce?

 

one is longer than the other
but seriously, dont quote me as gospel here, but I think one is a average over a longer amount of time, someone correct me if I'm wrong?

 

There are different fuel trim cells. Once the short term is at it''s limit it jumps into the next long term cell and starts adjusting again.
