My New Screamin' Eagle Street Performance Tuner

[NGOT8R]

Can anyone confirm the length of time the SE Pro Street Tuner can record data in a single riding session? Also, would it be best to record at least a couple of thousand miles before saving the recorded changes to the existing tune? Thanks

You only need about 15 minutes of data. Just ride a variety of speeds up a big hill several times in different gears to hit a bunch of rpm/load points for a few seconds each. Be sure to warm up the bike up completely first (get the oil hot).

Not sure how much data it holds. I never tried to record more than about 20 min. When you look at the data you can see how many cells you hit.

Gotcha. Thanks hulk. Now if the weather would only straighten up, I can get it done.

Finally had a chance to take the bike out yesterday and conduct one session of smart tuning with my SEPST. Upon returning from my ride and downloading the recorded data, I noticed that some of the cells had been populated in colors of Aqua blue and Red, although many remained White in color. Something else I noticed was the front cylinder actually only had one Red cell, while the rear had 10-15 Red cells. I only reached 44% throttle during the data logging session. I'm assuming the goal here is to turn all of the White cells Aqua blue in color? If so, it seems that this will be nearly impossible to do without scheduling a dyno session to be able to see and run the bike at varying throttle positions and then hold those positions for a minimum of 5-10 seconds each. Lastly, does anyone know why some of the cells were Red?

Find a big hill where you can run WOT in the higher gears.

I've only road tuned with a Power Vision tuner. I added the H-D wide band auto tuning module and let it do all the work.

Thanks hulk! I might see one of these auto tuners in my future. I keep trying to tell myself not to spend anymore money on the 2018, but then there's always something that I spy and would like to have. Will it ever stop? LOL
