I just ran 50 miles with my diablo connected to monitor ltft. I set cruise on 70 mph @ 1900 rpm. LTFTs were +1.56 on both banks on a steady cruise after 30 mins. STLTs bounced from -.78 to 5.00. How should I adjust the LTFT? - 3?

Don't worry about STLT.

Were there any changes to LTFTs, any other numbers? If they are rock solid, nothing up or down from there, only go with a -2 change. Drive another 30-50 miles and then remonitor to see how things are going. Remember weather makes a difference so try to log in about the same weather conditions (temp & humidity)

The ltfts were rock solid. For the first 20 minutes the readings were .78, after 30 or so 1.56 as long as i was on a slight incline or flat section. During declines around 4.00.
Thanks

yup, do as Canuck suggested... go -2% on your injector slope...


NICE Canuck!!
