I'm about to put .509 in my 88ci ultra classic. It will have S&S power tune headers, exhaust with 2" Baffles, S&S air box. I have a power vision tuner. Anybody have an idea of where to get a decent base map?

Thanks

 

No matter which base map you start with it will, for sure, need proper tuning to get the mixture of parts to work well together.
There are no canned maps that will be close enough that a dyno tune will not be necessary to get smoothness, response, and great mileage.
Other than that, you can convert your bike to late-model closed loop operation, which is by far the best solution IMO. Then use TTS V-tune to calibrate your fueling.
So, IMO, take your bike to a qualified tuner and get it tuned properly.
OR
Convert your bike to closed loop operation, read and absorb V-tuning procedures, and do it yourself.

I was thinking this too. As I already have the PV, adding a target tune would be the same thing, correct? I was going to wait to do this until/if I did a big bore, but it couldn't hurt on the 88".

 

If you’re up to spend some more $$$ (exhaust mods and extra tuning hardware) AND take the time to read/reread the PV manual (need link) until you have a clear understanding of what happens and how to get the end product (great running bike) you want, go for it.
Otherwise find the right tuner and go with what he wants and you’ll end up a happy camper without having the frustration from spending the money, studying the manuals and forums, plus the trials and errors from learning curve... just to get the bike running right.

A canned tune will get you by while you save up for a dyno tune. Hit up S&S directly. They will have a Power Vision starter map for your 509s. Also check with FuelMoto. They might have one as well.

 

I'm actually considering doing a thundermax w/ autotune. This bike is just going to be in its infant stages with the initial build. Kinda nice to think I can keep building up and the system can be modified to what I do, as I do it.

 

You’re better off with your first idea to add bungs and o2 sensors with autotune then add target tune and you’ll be good to go...once you get the knowledge gathered.

Dyno jets site says that target tune is not available for my 05 just auto tune pro. I'll be running power tune duals which are set up with 18mm bungs.

 

PV Autotune Pro with the wide band o2 sensors is over $400. I would run it with your PV canned map first and see if you like the results. Then you can decide whether you want to spend the extra $$$ to either get autotune pro or go to a dyno shop and get a proper tune.

 

As long as the OP is staying stock 88/stage 1, a properly picked canned map will usually provide an acceptable running bike.
Start adding cams, compression, porting, exhaust design change and it will be exceedingly difficult to find a canned map that will provide even a “decent” running bike.

So upgrade the system to the later closed loop with O2 sensors and learn how to street tune your bike. Without the O2 sensor system you will have no help in knowing where to make changes and easily get lost trying to figure out where to do what and when.
