hello all,
Having some dramas with what should have been just scale tune for diff gears, vehicle is a 2009 holden ve ss ute that is pulling timing on wot for a second.
i have attached a log and the file out of the vehicle.
it does not do this when rolling the throttle on only with sudden wot, i have played with burst knock to try and eliminate this issue as well as TM with no luck.
At 37.2 seconds is where this issue is happening causing a nice big flat spot.
The car has a medium size cam, unsure of specs, an OTR and full exhaust.
the car was originally tuned in SD mode by previous tuner who made a dogs breakfast out of it (original file attached also)
is there anything i have overlooked?
Wideband was reading correctly just not in scanner, afrs are good.
Thankyou all.
