SingleTipTerry Posted May 23, 2024 Report Posted May 23, 2024 Hello, Ive been having some drivability problems with my 1uzfe non vvti on a link g4x storm that i cant quite get an understanding of. At about 1600 rpm there seems to be a lean spike, Has a bit of a dip at the rpm when it does happen. Would happen every once in awhile but now has become more frequent. Just looking to get pointed in some direction to help diagnose this issue not really sure where to start. I appreciate the help very much Log: https://www.dropbox.com/scl/fi/9rmi81a8i5ioiau8ejyf0/PC-Datalog-2024-05-23-2-01-57-pm-Lean-spike-at-1600rpm.llgx?rlkey=zqlzmkskh449gf9e2cgzznid1&st=kb08mrph&dl=0 Current tune: https://www.dropbox.com/scl/fi/eba08cnre9a89vncngsk2/Sc400-Cold-start-adjustment-3.9.24.pclx?rlkey=r0hh9ea8vasohfpfst7cwz0zn&st=xewqzemz&dl=0 Quote
Adamw Posted May 24, 2024 Report Posted May 24, 2024 It is overrun fuel cut as your TPS is less than 0.8% and your RPM is about the deactivation RPM. Quote
