The Tuner SHOULD be reporting the exact same value as the speedo, both the gauge cluster and the tuner are getting the same data from your PCM for velocity calculations. If your speedo is off, you need to have the stepper motor checked out in the cluster.
As far as playing with timing goes though, you can slowly add some timing and see if you hear pinging or get a knock code. What are the available setting for timing? Let me know and ill cook up some good setting
placements for you.
Here are all my settings right now.
Transmition/economy and Tow performance program)All are the same as follows
WOT STD shift Conversion lock points Rev limiter
1-2:5000 1-2:0 1:lock 5400
2-3:5000 2-3:0 2:lock
3-4:4900 3-4:0 3:lock Shift Firmness
2-1:0 4:lock 1-2:0
3-2:0 1:unlock 2-3:0
4-3:0 2:unlock 3-4:0
3:unlock Timing WOT Fuel
4:unlock 0.00 1.30
Idle RPM for all 3 settings
Performance tune-All the same exept for two
Rev limiter WOT Fuel
Hope all this helps you.I would like to stay in tow performance for most of the time untill spring/summer when i will do allot of the Performance tune.By then tho,i will have custom tunes
