Question Step by Step using SERT

I need help locating step by step instructions on building a map from the ground up. I have an 07 Custom Softail with a SE A\C and Vance & Hines Long Shots w/ Quiet Baffles. The throttle is sluggish and there's lots of decel popping. The 159AE003-A1.MT6 base map is loaded. Here's where I need help.

After loading the Base Map, do I just ride for some time so the ECM can adjust to it?
-then-
Do I Disable Knock Control, start up the Data Mode and ride at various conditions for a while as I read some people say? Or ride using the HD instructions for data logging?
-then-
Which map do I start adjusting first? and how many times do I readjust the same map? What's the map adjustment sequence?

This is probably written somewhere and I just haven't found it yet. Maybe there's a SERT/ECM programming for DUMMIES manual somewhere.

Any help is appreciated.

Thanks

There is a wealth of information concerning the SEPST in this thread and I think there is a step by step in one of the posts.

Is this orange with a button on it, or is it black? Screaming Eagle Race Tuner is black. SERT

Screaming Eagle Super Pro Tuner is orange. SESPT

If it is orange, quit calling it a SERT, it is a SESPT. They make both.

If it IS black.....
Black one is made for dyno tune only. (but come back and possibly some advice can be given) Black one has NO data log features, and was sold thru HD up to 2008. Black one became TTS in 08 and was the first to add data features. SEPST soon followed.

If it is orange, follow jluvs2ride's advice, and was sold thru HD since 2008.

Got a part number on it? Got a disk? What is the disk entitled?

Where in PA are you located? I ask, because if it IS black and it IS a SERT, then I would recommend taking it to Pocono HD and have it tuned. Pocono and Gails HD are the only two dealers I would EVER recommend doing a dyno tune to my fellow members. Robin works Gails and JD works Pocono.

I really disliked the SEPST for quite a long while. Was buggy and didn't work well. Now? That is all in the past, and has a Histogram function for data gathering and the latest software is a free download. I like it.

Yep it's Black. The software has both Tuning and Data modes. Data mode works on my laptop in the garage, but I'd have to carry it with me if I hit the road. But you know what, I'm not far from Pocono HD either. About 1 hour.

So you don't think it's a good idea to try to tune with the Data mode and SERT?

Sert # 32114-01A-SubA

Disc # 32117-01J

That's data mode and not v-tune mode. My bad. Go see JD. there is no way to collect data to help yo adjust the VEs with that tuner. And... VEs are king!

Mine's black not orange it can log data and it does have Smart Tune capability. It's the SEPST.

32114-01a is for a SERT, not a SEPST. Look real hard at that -01a, and that should answer it all. The oldest PN for a SEPST is -08a

ANd... let's ask the OP this.... Jamn... does your black VCI have a button on it that you can push?
