Bonneville America Forums Forums Technical Forums Performance Mods Dyno tuning

For some reason I am unable to access the Tune and tuneECU forums, so will post here.

I have a 2009 EFI America w/ TORs and no snorkel. It pops a bit on decel, cold or hot. Other minutia includes a K&N and iridiums. I am considering getting the bike dyno tuned to eliminate that pop and just to see how much more performance I can get from the bike.

I have been surprised no one on this forum has mentioned Power Commanders.

Before dyno'ing, I plan to get Nology coils and the hot shot regulator/rectifier. I do not expect these would have much if any impact on the dyno, but would like to have the package complete.

So how much does Dyno tuning typically cost and would it be expected to benefit a bike like mine?
Why no PowerCommander interest for these bikes?
Any suggestions prior to the dyno?
I'd like to get as much out of this engine short of polishing, porting, or boring.

Dyno is always a good idea both to extend longevity and gain power. I am not sure with an EFI bike but I know a properly set up bike with open pipes and intake should sort of pop on decel if jetted correctly. Not loud backfire or eccessive popping but a sort of rumble.

Call or email: http://carpenterracing.com/sbp_bonneville.htm for a EFI Tune Quote, they can get your bike to be the best it can be, with the Mods you mentioned. They aren't that far away from you.

When I made my modifications the local shop/dealer recommended the PowerCommander route. They do have plenty of experience with it. At that time the PC module was $350, install was another $50 and the dyno time was another $350 minimum.
They are a Triumph dealer and would not have anything to do with altering the ECU themselves. They did let me, and even provided suggestions, use TuneECU to tweak & load a map "good enough" for me to ride out of the shop after the engine work and get to the other performance shop.
I didn't really want to to add something that altered the signals from the ECU and couldn't (at that time at least) make any changes to the ignition timing, only fueling. I do believe the current PC (5 maybe?) module does have more features than the older ones. I opted to travel a bit for a tuner experienced with TuneECU so the ECU would simply have the needed tune/map for the modified configuration. Cost was $350 plus gas and a day of travel there & back.

$350 dyno time! Holy crap! Either they are robbing people or it was quite a few runs.

That $350 was the standard rate for the 3 local shops (all PowerCommander minded) I called as well as the distant TuneECU tuner.
Seemed reasonable for the out of town TuneECU route. Since the operator needs to either read what was in my ECU or load a known map/tune for a stating point. Make a run for a base line. Evaluate, edit, save and load the modified map. Do another run, evaluate, edit, save and load the newly modified map/tune. Repeat...
While he had an extensive Triumph library of tunes, they were mainly for the Rocket & Speed Triple lines and a couple of Thruxtons. He said I was the first 904 America he had on the dyno.
Not as easy as with the PowerCommander I imagine. Most shops really pushed the PowerCommander and I think they see it as a money maker.

My 2005 America is carbs of coarse so I do not have to worry bout this.

On the other hand on My Rocket I use TuneECU. You might want to check with any KTM dealers in your area. They use TuneECU.
I am going to look for someone to Dyno it as soon as I finish the mods on it.

If I had a EFI model America or Speedmaster I think I would check out Triumph Twin Power and what they have to offer.

I paid less than 1/3 of that for my dyno runs, he is a friend of mine but I didn't think he discounted it that much.

If I had an EFI bike I would contact TTP who has mod-specific tunes & tools (OBD cable) ready to go.

Dyno runs and EFI dyno tuning are separate issues...with separate charges.

Marcellus, have you inquired about pricing in your area?

I see the current Powercommander V unit itself is priced at $399.99 at their site. The AutoTune add on is a little less than a custum dyno tune but still pricey at $325.
TTP with his auto loader and cable is not cheap but much less money. And going the DYI route with TuneECU & a ~$20 cable may not give optimal results but is always an option. Not to mention the TuneECU app is a really handy tool to have available for maintenance and troubleshooting.

edit: wish I could spell the words I intend to write!

i would recommend selecting one of these that close matches your modifications.

easy to install and much easier than doing it all from scratch yourself (and I have)

Yeah, I guess I will mag10, thanks. I guess I am confused and disappointed it's not as simple as a Power Commander and a map, but TTP looks like they have done the appropriate work and have the testimonials and reputation.
I dd not see a Stage 2 kit for Americas and Speedmasters. Odd.

Being obsessed w/ my bike the last few weeks, I have done a fair amount of reading on TTP EFI Stage 1 Torque Induction Kit... and moved it up on my schedule. April or May.
I will post back here with commentary on the installation and results.
I need get the 24,000 mile service and a few other things done prior.
