Why would you have to do that? My Indy can tune my bike and it has the SERT.... I can even tweek items in the map with my laptop.

 

You can tweak but will HD give you a new map to upload? That is where they get you.

 

And so here is where I see different comments about what the person got at the dealer. A few people claim to have purchased the SERT, but didn't receive any software. So I'm wondering now, is if all they purchased was the Stage.1 map. I think some dealers refer to the Stage.1 map, as the "race map", or they are calling it the "SERT", either through ignorance or deceit.

I know one thread a while back, I asked the guy about his 450 dollar purchase of the SERT, and claimed he did not receive any software. The SERT was, and may still be, written by Mastertune. I think there was some falling out, and Mastertune launched their own version, called "TTS". Now this is all 'my understanding'... and I may be completely out in the woods on this.

There is a TTS Mastertune section in the Tuning forum.

 

I use the SERT with the Daytona TT WEGO. Works like a charm for me; download the data, make the VE corrections + spark advance via SERT, upload, ride & repeat.

Not the simplest but downright effective.

 

Rich,
The original SERT was written by TTS. When HD went with the new SEST, it opened the door for TTS to market the original under their name.

The nice part is theres some stuff in the Mastertune that HD didnt want in the SERT, so you get more toys to play with...

Whats even better, is the Mastertune doesnt have all the bugs the SEST has

 

This is the route I went with my car. Datalogging hardware/software, tuning hardware/software, wideband o2 sensors, boost sensors, etc. It can be very addictive

I intentionally avoided that route on my bike because I knew I'd end up doing more tweaking than riding, but I imagaine I'll give in at some point, and would likely go the TTS route.

I'm curious though how you datalog on the bike? Is it stored in a memory modul that you hook up to the laptop after, or do you actually need the laptop hooked up during the run. If the later that would seem to make it difficult to tune unless you are on a dyno.

 

were you able to use O2 sensor with the tts, cause u don't with the PC?

 

Laptop running in the t-bag, hooked in real-time to the serial interface behind the electrical caddy cover. My laptop runs on it's battery for a couple hours, more than enough time to get a nice 30-40 minute tuning run. I work through the throttle position and the amount of load...(I've lots of hills around me) go through town, and then out for some 70mph+ stuff on the highways. Works quite well.

I may even invest in a small vga screen to attach to the bars at the riser, so I can really hit each cell when I'm out doing a tuning run. Yeah, a dyno run would be the best, but since all I've done to the powertrain is Stage.1 a/c, and the pipes... I'm not too worried about it. Now when I do cams, go to 103 or 107 cubes, and headwork... I can start with a base map for that setup, but I will then get her dyno'd.

 

That's the cool part of the TTS, it's only software... because you already have all the hardware you need... it came stock on the bike. But to answer directly, yes - the TTS uses the existing stock O2 sensors.

 

Damn I wish I had gone that route now....... LOL I have only had my pcV about a month!
