How do you handle a car on a dyno?

First, put on the wideband and set up all your ---- prior to arriving. That will save you a ton of time. Make sure everything is working, especially the vehicle.

Secondly, if they are required to operate the dyno, don't let them for a second, wander around or leave. Some places try to screw you by doing that.

Make sure the car doesn't smoke, leak, or have any issues that make you look like an ***. Tell the vehicle owner as much - "I'm going to look like a real ***** strapping your car to a drum with how it smokes, fix your broken ----, *****." It is important to do this. Some dyno shops will refer business to you if they think you have your head out of your ***.

Make sure the boost controller is already installed and you've tested that it works. I've had a dozen situations where the boost controller isn't installed "It'll only take, like, two minutes. We'll do it when the boost needs to be turned up" and then they realise they don't have the installation instructions and have to drop $50 in dyno time ------- around over something basic. Plus I've never seen a Greddy Profec B spec 2 that worked, and that OMG JDM HT-APPROVERD Turbosmart digital pillar mounted EBC has failled both times I've tried to use one. "The boost controller isn't installed and tested? Get fisted, you are a n00b and you are deliberately wasting my time."

Remember every time you walk into a strange dyno shop... you are either going to be confronted with complete idiots or someone who knows a lot more about tuning than you do. I've met tools, I've met regular people working hard and learning their lessons, I've met people who are what I'll be in five years, and I've met wise, wise old men. The latter two are pretty rare, sadly.


Max is correct, some places want you to pay $100/hr and stick you to handle the machine. Well, ---- them, I'd rather operate the dyno myself anyway. Dynojet, Dyno Dynamics, Dynocom so far, hopefully Mustang come June. It's not always possible if the dyno's computer monitor is stuck somewhere ------- stupid where you can't see it. Dyno4mance outside Atlanta has a couple projector units they use so you can't ----------ing miss a lick. Good stuff, but they don't stick you to operate the machine yourself. I run dual laptops on BRMS' Dynocom (I sorta work there?), one to tune and one to dyno with, and have another guy operate the car on the rollers... good setup, but I really need to make a kill switch so I can turn the vehicle off if AFRs get stupid or power output drops for no reason. Yelling real loud or throwing your Taco Bell at the driver works, but one day the car will be too loud or I'll miss.

Best thing you can do the first time you're dyno tuning? Let go of the steering wheel at some point. If the car is strapped correctly the car won't go anywhere, but all the tire smoke and everybody running around freaking out is great.

Strap sideways, not just crossed up front and back.

Ill 2nd the "get the boost controller setup first". Theres nothing like jerking off for 4 or 5 runs trying to get it set right.

I spent 9 hours on a dyno fixing problems with a car that came in running pretty solid no cel's so if your cool with the peps of the cars just do a solid go through bring tools test light, timing gun, manual the list goes on. On the actual dyno was like 3 hours but the Guy was way cool and charged us for the 3 that doesnt happen in the normal world
