That is why I am getting away from SERT or TTS. Don't get me wrong, the TTS was the first thing that I looked at. I purchased the USB to serial cable from TTS to try and talk to the SERT, but to no avail. And yes, the serial port is working.
You said something that hit the nail on the head. Your old SERT worked fine on your XP PC 8 years ago. I should not have to upgrade the SERT or whatever just to make changes to it as I change items on the engine. This way, I won't have to worry about now.

The only reason I said my SERT worked on XP is because that's what was out when I had one. My TTS has worked on XP and Windows 7. The TTS software updater checks and updates the TTS software and map database when a newer version comes out.
Do you have the proper headpipe to install the EMS O2 sensors?

I just don't like the fact you have to send it away for the tune. If I were to spend that much on a tuner I'd go with a Thundermax. But I know some guys that run the Rev Perf EMS and love it. Good luck on your choice.

Glad someone ran this thread as I'm interested in the EMS also. I do not wish to hijack anyone else thread, but I had to respond to this. The Thundermax is an Alpha-N system, which means it operates on throttle position and RPM tables only(no vacuum to sense load on the motor). It will dial the fuel in after numerous resets, but has no adaptive timing feature-ion sensing. I've installed T-Max on several bikes(other than mine) and have had to do extensive changes to the timing tables to stop pinging. This is why I feel the EMS is a much better choice if you want auto-tuning.

This is all about running closed-loop, with wide-band 18mm sensors, located up near the exhaust ports, coupled with a stock ECM calibration that taps into native capabilities of the ECM that allow it to do extraordinary things that HD is not allowed to market due to EPA emission restrictions. It is highly propitiatory and is a result of a great deal of research.
After I installed mine, my fuel mileage stayed the same. But everything else improved. The pep and pull of the 103 is sensationally better than stock, the sound and torque all through the power band is eye-opening, ear-catching, and I don't have this and that hanging all over my ECM. In fact, there is NOTHING hanging off of my ECM. And it's my stock ECM with all of the built in safety features and knock sensing.
This is a complicated system made simple by RP for the guy who wants closed-loop motor load sensing in real time, every time, all of the time, and that just wants to ride. No annoying decel popping, no fuel tables to mess with , no timing issues, no spark advance issues, no front or rear cylinder AFRs to balance, no "you know a good tuner" issues, etc. All of that is history with RP EMS. May it rest in peace.
Simply stated, you get what you pay for. But if you enjoy messing around with fuel and ignition tables more than riding a perfectly tuned motorcycle, then you might want to explore other "tuning" options.

Sorry, but you are incorrect UNLESS you are changing displacement by 20% or more. Try reading the EMS website and you will understand how and why it works so well compared to the Alpha N tuning systems that so many spend so much time and money on and seem to never get it right. (not to mention forum time on subjects covered over, and over, and over, and over again.)

Why would you need to dyno-tune the T'Max? You should be able to install a close map and let it auto-tune AFR's from that point on.
