Hello all,

I recently installed S&S 509 cams in my 06 road king, I also have new lifters and adjustable pushrods as well. I'm at the point now where I'm putting everything back together, and wanted to know what I needed to do after the install to make sure the bike is running and running well? I've never done work like this before so I'm not sure what steps I need to take once I've got the bike back together. Obviously it needs oil and fuel, do I prime the oil pump first by turning the engine over a couple times? Can I run it for a little bit on the stock tune just to make sure it still fires and there's no leaks?

Also, I plan on installing a 2 into 1 exhaust very soon since I've got the stock exhaust off. In terms of getting it tuned, will the fuel pak or power vision have a fuel map for my cams and exhaust or should I take it to someone and have it tuned?

Any advice would be appreciated, thanks y'all

 

I understand why I've heard so many negative reviews when it comes to "Canned maps" that are out there. Every engine is different for sure, so I'd suggest finding a good dyno guy when you're ready.

 

I agree, I had an fp3 on my sportster awhile ago and I think it worked but it was hard to really tell a difference. There's a shop nearby that does dyno tuning so I might hit them up. Is it safe to run the bike for a few minutes on the stock tune before I take it? I just don't want to bring it down to the shop and run into some unrelated issue since the bike has been sitting in pieces for a couple months now.

 

I am not sure Fuelpack will get you where you want to be. And I think you need an 07 or newer Touring to use AutoTune with Power Vision. At any rate you will also need something to flash the fuel and timing maps for each cylinder after the modifications you are proposing. Also note that if you take it directly to a tuner they will need to load a new basemap closest to your configuration before any tuning.

So if it was me I would continue the modifications you are working on, I would make my decision for a Flash Tuner, Install it after all my mechanical mods are completed, load the Power Vison Fuel Map that is closest to your build, then take it for a ride. If all is good you save money on the tuner. If it has startup issues or sluggish zones I would make modifications to the Fuel map.

FYI I went down this road on my 2003 and landed at removing the Power Commander and installing Thundermax.

 

What made you switch from the power commander to the thundermax? I've never used either of them but I was looking at them awhile ago

 

I recently had a stage 2 done to my bike. After it was done, I drove it 34 miles to my tuner. Ran like sh*t, but it made it there. Both the Indy and the tuner told me it would be ok to drive, but did tell me it will run like "sh*t!" I had no previous tuner installed prior to the dyno.

As far as canned maps, I feel like if you were to purchase one from an online dealer and they loaded a tune on there to get you going after the work was completed, cool, but I would still take it to a dyno tuner. Thing is, people get that tuner installed and never take it to a dyno because they feel it runs great. A dyno tune IMO is money well spent!

 

A dyno tune by a competent operator will always be the best option for the best tune. However, knowing about a competent dyno operator, and/or having one in your area, is not always the reality. A poor dyno operator is worse than useless. Not everyone who owns a dyno, should be tuning with it... they are out there..

OP, IMHO, in your situation, I would buy a PowerVision Tuner from FuelMoto, delivered with a map for your mods. I would download the map before starting the engine. Then I would take it for a ride.

After the thrill of that first ride, I would do a basic auto tune session, or two. You want the average cell change to get to about 4%. FuelMoto has several tutorials about how this is done. It's pretty simple. At that point, especially for a street driven bike, you should have an extremely well running bike with new cams

If I had an issue with the tune, I would data log it, then let FuelMoto tweak the tune.


FWIW
I live in an area where there are no (known to me) dyno operators that I would trust to tune a bike.

I purchased a PowerVision flash tuner many years ago. I use it for OEM improved, Stage I and Stage II (bolt-in cams) mod tunes. I bought it from FuelMoto and their maps are usually very close. I will flash their tune, then do a couple basic auto tune runs to dial the canned map to my specific bike's VE tables... A few times, I have done a single AT session on a FuelMoto map and been at or below 4% average cell change on the first AT session.... Those were really good maps. If I ever had a tune issue, I can do a data log, send it to FuelMoto explaining the issue, and they will tweak the map and send it back. Their tune support is excellent.

Anything more than bolt-in cams, like a big bore kit or my crate engine install, I have it broken in on the dyno, and dyno tuned by a competent dyno operator. Unfortunately, I have had to put the bike on a trailer and do a road trip to get that accomplished... but IMHO, it's worth it on those bigger builds. Especially when the pistons/rings need break-in.


Good luck with your mods, and your tune...

Whatever your tune decision, enjoy!

 

Good advice above!
fuelmoto and their PV will pay for itself many times over. Top notch after sale service and support.
On a side note I did a cam upgrade and received a map from FM then followed it up with a dyno tune and the graphs were almost identical. So that says something about FM.

 

Per everyone's suggestions, I'll look into getting the power vision. Does the standard power vision come with auto tune? Or do I need to get the auto tune pro kit on top of the standard power vision?

 

There are currently several versions of tuners offered by DynoJet.

The full service PowerVison tuner is the one I bought & use. it has the ability to do the Basic Auto tune sessions. If you want to do advance auto tune sessions, then an additional module/kit is needed.

This is an old comparison chart with old (supply chain issue) prices.

The Dynojet Power Vision PV-2B Harley CAN(PV-2B) for your bike, from FuelMoto is now $539.99 and if you call, they will add the appropriate map to the tuner for you before shipping.
