Like the old fill the tank with new fuel to reset the Octane scaler internet myth, there appears to be another one gaining popularity. That myth is that Lean Cruise actually functions on non Holden cars, both EFILive and HPTuners have explained that just setting the calibration variables like a Holden will not give Lean Cruise on a non Holden Platform.

For those that can read (or rewrite) assmebler code, here's the actual check in the PCM operating code to ensure Lean Cruise will not function unless the vehicle is a Holden.

EFILive does NOP encourage you to change this code :wink:

Cheers,

moveq #2,d1 ; #2 = Platform is Holden
cmp.b (byte_0_1E5C5).l,d1 ; Check against Platform type in cal
bne.s loc_0_29A96 ; If not the Holden then skip Lean Cruise
jsr sub_0_2F68E ; Jump to Lean Cruise Subroutine

loc_0_29A96:
jsr sub_0_38372 ; Jump to Knock control subroutine
