Dyno operation help needed...

[Bayer-Z28]

I found a guy here in Bristol that will rent me some dyno time and I have some questions. This guy and his friend have a couple Alcohol 1st gens with blowers running over 900hp and he mentioned that the dyno has to be calibrated. -Prolly just good for tuning. He said he doesn't tune LS vehicles but if I have the software, he can rent me the dyno. I want to pick up EFI Live and some WB02's around spring time... And possibly a FAST intake with new injectors. I would LIKE to try a couple small changes once I get used to the software. I was gonna have Pizza call me and I was gonna ask him some general Dyno questions, but I figured a thread would be just as effective if not more.

-I've been around dyno's a couple times but their operation is somewhat unfamiliar to me. I understand the tie down and I noticed how Pizza would roll the rollers with his feet to make sure the car was settled on there and then check the straps again. -I like that idea.

-Is there just a static/constant load on the dyno?

-The remote that you bring into the car, I take it that's for the computer program to start a read/measurement for the dyno pull, right?

-What things are there to watch out for? Besides a newB trying to tune his own car...... The dyno itself just seems pretty cut and dry. Chock the wheels and strap the car down.

I'll know more come spring time, but if there's anyone who wants to come by and help out, you're more than welcome.. I appreciate any advice given.
