Tuning the VEC1

[SMCBUILDERSINC]

Can someone copy the tuning section of there VEC1. I didnt get that part when I bought mine from a fellow VCA member. I dont know if thats too much work but if its possible then that would be great.

Also, my new Viper has head work, cam, full headers and 3 inch pipes, airbox and T&Ds. I was thinking of going with +4 and -10 to start. Give me some opinions.

Thanx

Start with 0 and 0. Go for a drive and start accelerating from 1K -3K RPM with half throttle. Keep on clicking 2 notches back (counter clok) and see if you feel the difference. At the time when the car feels the quickest back down a notch and compare both positions. At that point see where the VEC1 lights are. You should see one before the last light up while accelerating.
Next move to the second knob (right). Start this process from 3K to WOT acceleration. Do the same as above but clicking clock wise. This time at WOT the last light on the right should be on while at WOT.
Then you are done!
I'm at -6 +8

So your high side adjustment is in the positive? It seems many of the other users are finding there best results in the negative teens. IM at plus 8 and minus 10 and I feel that the engine is running smoother and alittle more sensitive to the pedal. I beleive that when you go into the positive it decreeses timing advance, so thats seems like it would take power away.
