ECM Tuners
New to the electronically controlled engines, everything I own except for the new bike is 1974 or older. I now own a 2006 FLHTCI and looking to get a tuner for the ECM. Which one is the best and why?

In 06 only the Dynas had the 02 sensors (I believe). Iw ould suggest you talk to people in your area, club, buddies and find out what works for them and what is serviced best where you live. I use a TMax in my 07 Heritage Classic -- no one seems to know much about them (Dealers and Indy's in my area) so I'm on my own when it comes to changing and diagnosing issues (there is the forum, but I don't always get very many answers). I can recommend the TMax (non-autotuning if you don't have the 02 sensors), a lot of people seem very happy with the PC items.

I'm not talking about a Dyna Glide, I have an Electra Glide Classic. I'm talking about Dynatec. I run a Dyna 2000i ignition in my 1974 XLCH and like their products. I was wondering if anyone has had a positive experience with the Dynatec tuner, or is the only controller out that is worth anything just the Power Commander and I don't see an O2 sensor on the exhaust anywhere.

I don't think there is one right answer, and I don't think there is a bad system out there today. There are disadvantages with all of them but you basically get what you pay for. What is best for me or another guy may not be best for you.
Without O2 sensors you tune by the seat of your pants and spark plugs as you have no other way to determine how well the A/F ratio is doing... unless you hire some dyno time. With all these tuners, you start with someone's best guess and go from there. The best guess is probably good enough, but it may not be the best you can do.
Simple systems like the dynatec or the fuelpack have limited adjustment capability, but are easy to toy with. The PC is more sophisticated. These tuners trick the ECU into doing things they want. The more sophisticated SERT or TTS will program your ECU directly, and will give you many more settings to toy with, and you don't need to add hardware. Again, they give you a best guess and you go from there. You can be pretty sure you will be able to get a very good tune with these and be able to tune out decel pop, fix surges, hesitations. You can't really be sure using less sophisticated tools, but many have had good luck with them.
I am comfortable around a PC, so I think something like a TTS is the best, but the simpler more hardware based fuelers may work well enough for you, as long as you keep them dry. You don't even need to turn on a PC to use them, which may or may not mean a lot to you. You can think about the dynatec having four screws to twist and turn, where the TTS has maybe five tables, each with about 100 screws to twist and turn, a lot more parameters to play with and to learn how to play with...
I hear a lot about the fuel pack, PC, SERTs, thundermax, TTS but don't recall anyone mentioning using the dynatec. Not that its a bad product, those guys have built some good stuff.

Thanks for the insight there Coldcase, I appreciate your explanation very much. Only it just makes my decision harder. My other bike is a 1974 Ironhead Sporty so tuning by the seat of my pants, by my ear and by the plugs is very familiar to me. So now it comes down to how much tunability I want to have. Once again thanks.
