Default Tuning Vortech, Green Dynojet Button?

Have been doing some tuning this week on a local dyno myself, but I don't have a Dynojet manual or WinPep helpfile handy.

Can anyone explain the Green Button on the Dynojet controller and the proper procedure for sampling? Is sampling the same thing as recording a run, or a calibration test?

TIA!

Hit the green button to begin sampling and once again to end the pull. Angelo

Thx, so sampling = dyno run?
The sample is the run?

Not some type of rpm/tq test?

yes the sample is the dyno run, push the green button as you nail it, push it again when you want to stop 'recording.' When you push it to end the run a graph will come up on the screen, if you want to go again push the green button again and the tach/speedo will come back up and you can keep making runs without getting out of the car.

Just dont press the red button by accident when you nail it also let the dyno brake slow it down and dont touch the car brakes (unless you feel the car start to roll forward). You will get used to pushing the green button and then hitting the red one quick after a few tries..

Thx Guys!

Also, when at the end of a 4th gear run, it is better to leave it in gear and use the dyno brake until lower rpms before putting in neutral, eh?

I never would use the car's brakes, but placing the car in neutral at the end of a run before dynobraking (at higher rpms) causes the PP to buzz/spin kinda fast/weird or something.
