Gotcha. My next question would be how do I read what the tune is calling for? I originally plugged in my SCT scanner (which holds the Lund tune) into the OBD port. There was an output port, on the scanner, that plugged into my laptop for logging via the LiveLink program on my laptop. That's how I got the figures I previously posted. What I was asked to log was the following...
accel pedal position relative
engine coolant temp
intake air temp
knock sensor
load
maf frequency
measured afr bank 1
measured afr bank 2
rpm
short term fuel trim bank 1
short term fuel trim bank 2
spark advance
spark advance V2
throttle angle actual
torque source
total misfires
VVT exhaust bank 1 actual
VVT exhaust bank 2 actual
VVT intake bank 1 actual
VVT intake bank 2 actual
vehicle speed mph
I don't have the scanner plugged in right now but I recall it had some sort of diagnostic/logging feature. Don't hold me to that. Will this read what the tune is calling for?
