Title: trying to get better fuel mileage out of my lead weight Post by: krazydbiker on July 05, 2013, 01:05:08 PM well thanks to this site and a ton of reading i am at the desired power level i was looking for
my goal is now to try to get 20-24 MPG, since this car is horrible on fuel, some timing adjustments have helped, but the fueling could use some work, so far reading on this site it looks like everyone has been dealing with narrowband, disabling closed loop and adjusting from there, this is a wideband ecu, so i was a little confused on where to start, i tried to basics first, playing with LAMFA, KFLBTS, tweaked FKKVS, but ended up putting all back to stock, as there was no change for a lambda higher then 1, still ran a lambda of .95 - 1.0 lambda can anyone tell me if im on the right track? im assuming a wideband ecu can have a set target vs narrowband there is an upper and lower limitation of lambda controller called FRMLASHO - upper threshold for mean value of lambda controller, FRMLASHU - lower threshold for mean value of lambda controller thanks, if there is something i missed when searching let me know Title: Re: trying to get better fuel mileage out of my lead weight Post by: phila_dot on July 05, 2013, 03:15:39 PM Check my lean lambda constant thread and pay attention to elray's comments

edit : might have found the lambda constant atleast, dis-assembly looks almost identical, but with different locations as expected location = 93590 in my file for constant, now to find the rest, thanks! |
