RE: 4 Hours for Dyno?

Dyno sessions (costs and time slots) can vary by dealer, and also by what is being done. For new setups with mapping and tuning 4 hours is pretty standard as they allow a half day for bike setup, mapping, minor tuning, and performing what is usually 3-4 pulls after everything is setup. If you already have your bike setup when you take it in, some dealers will charge a flat rate of 1 hour for 3 dynopulls. Large inch performance builds can often charge a full daywith rates varying between 500.00 and 750.00 per day but includes extensive tuning which can sometimes take more time than allotted.

Sound like you dealer is on par. Just make sure you're happy with the tune after and that it doesn't pop and fart.

RE: 4 Hours for Dyno?

bdavis...It tookBrian at Scooters Performance2-full hours to Dyno my '04 Road King, you can see my set up by my signature. It included rolling the bike into the Dyno area, loading it on the machine, tying it down and adjusting the safety devices on the Dyno, attaching the various monitoring and data cables, Air/Fuel sensor, etc. Then, there's the actual set-up of the computer, loading your bikes individual data, e.g., pipes, a/c, cams, headwork, and so on. After all of this is done the Dyno Tech performs his baseline run to establish were you are right now. After all of that, at least in my case, he did three (3) power runs, tweeking as he goes along. After it was all said and done, I was looking at 88.5 lbs TQ @ 4050 rpm (original 77 lbs TQ) and 77.4 peak HP (original 69.8 HP). I don't think 2 - 3 hours is out of line, however, I do think 4-hours is a problem. Either you've got a very exotic set-up or the Tech doesn't know what he's doing. To me,a flat rate for a custom Dyno tune might be the best way to go as long as you trust the guys doing the work.

It really depends on how good ya want it to be...

The "best" results take more time, particularlly with SERT tuning. Even 10 hrs is not unreasonable.

It all depends on the proficiency of the guy doin the dyno. How fast he can change the numbers accuratley and how good he is at keeping the throttle at the desired throttle position.

I'm finding a lot of dealers (in my area)are doing a flat rate based on 3 hr for the first dyno tune.
After that it's a little less as they only need to tweak future changes.

Here's a question. I have a '05 rk custom with a carb. The carb was rejetted when I added the pipes and AC. Would a dyno benefit someone with a carb, or is it just done to see the numbers? What does a dyno do, if you have a carb?

RE: 4 Hours for Dyno?

It sounds about right if the tune is worth a crap.

I used to build supercharged Mustangs to race and had one dyno tuned. I drove 6 hours to meet the tuner who was in town just for tuning that week. He spent 20 minutes on the car and was finished. It made 520 rwhp / 544 rwtq. I heard he was one of the best and believed it afterwards. He used to work for Ford and help designed the ECU for the Mustangs/
