Default My Tune

Please excuse my ignorance(which on EFI tuning is almost unlimited),but is this software not needed on the later SEPST.

Maybe you're not grasping the concept here. Lorance is basically tuning his bike on his own. So, "not needed" is sort of an open-ended question.

I think what you are saying is that the newer SEST software includes Smart Tune whichs also intelligently adjusts the VE tables based on Data Runs. The TTS has a simular feature called VTune.

I used My Tune and had good results. It is a great Software, but when I got Smart Tune I figured I didn't need it anymore.

I did say my ignorance was almost unlimited,at least I was right for once.

The MyTune software developer claims the algorithms used by MyTune are better than whatever the Smart Tune feature uses. Still, my main purpose being losing the knock, the Smart Tune feature does not do spark advance tables.

Occasionally my dealer has a trailer set up in the parking lot giving a free 4th gear dyno pull. I think I'll do that next time that's going on just for kicks. Ha, this is the first time in my bike's life it has ever hit the rev limiter! I hate hearing them rev so hard haha.

With out actually dissassembling the software it is hard to know what algorythms are used in My Tune, Smart Tune, or VTune. So to say one is better than the other makes me wonder. However I had forgotten that My Tune does suggest timing changes where the others do not.

I for one would be very interested to know the outcome if you get a chance at the Dyno.

Do you have about the same setup on your engine as I do? (VH BR 2-2 and SE Heavy Breather on mine) (No other performance mods)
Yea, not too far from it, mine is a stock motor, with the se heavy breather and just installed rb racing lsr 2-1 pipes....

So am i understanding this right,the MyTune software is compatible with SEPST & offers extra functionallity?.

Do you guys mind if I ask in this thread,the advantages(or not)of TTS over SEPST.
It seems the forums I read each concentrate on a particular Tuner,& I don't read much about the SEPST,I didn't realise till I read this thread that SEPST could be adjusted by an owner,like TTS can(hope i've got this right).

I do not know a whole lot about either but I think the TTS one and the SEST are somewhat equal.

I did not know a home user could modify anything either but I am learning. When I first decided to do this you should have seen me. I found a USB cable and tried to hook the SEST up to my laptop and look at stuff, of course nothing happened. So I ask questions....I actually bothered Frank at MyTune quite a bit but he is so helpful. To make a long story short I ordered the interface cables from TTS and then I was more dangerous. So now I see there is a proprietary cable that goes from the bike to the serial port on the SEST and then the USB cable to the laptop. So I hook it up.....nothing. So I bug Frank again and he tells me I have to have the HD software too. Geez....so, I procure a copy and NOW it is all making sense.

So anyway, if you have the SERT or SEST you will definitely need the HD software ($29.99). (MyTune is optional) I can get you the HD part # if you need it. If you get the TTS it should have the software with it but be sure to get cables too. Once you have this (and I cannot speak for TTS) you can use MyTune or even change numbers manually and reflash your ECM. If you end up working with the SERT or SEST, send me a PM and I can help you as far as basics on how to save a map and do a reflash, etc.

Where can you get actual detailed information on the SERT-SEST-and SEPST. I can't find anything on line from H-D. It does not seem to be something you can purchase through the catalog like other SE performance parts. What are the differences between the 3 of them?
