Hi, I'm interested in this also. Can you clarify what you said?
Flash based = like pv? Re-wrights the ECU?
Which is a better system for timing and spark? Can you recommend a product?
My mods are a new engine, heads, throttle body, cam 10.25:1 103 in a 2005 softail
I have a pc3 but am thinking if I get no joy with tuning I may upgrade, probably something with a auto tune. I don't have 02 sensors but can fit some.
I just want a reliable well tuned bike.

Thank you.

 

 

A flash based tuner rewrites the stock ECM. This is compared to piggy back systems that don't change the ECM but change the signals coming out of the ECM. Tmax is what I consider a stand alone unit. You do flash it but only with Tmax.


Flash based is what I prefer for 99% of the tunes I do. TTS IMO is the best tuner with the most useful features. It actually address the timing side of tuning like no other tuner on the market. There aren't codes to unlock this feature or that feature. Everybody get the same with TTS. With one data collection run. TTS address's wide band and narrow band VE mapping, Main spark table and spark temp correction, and EGR tables. The rest of them will address wide band and narrow band but not at same time. As for as the other feature of spark and EGR (CDE.) Plenty of threads to read about how they are lacking.


With an 05. You have no o2 feedback. You can buy all the equipment, learn how to tune, and spend the time doing so. Or you can spend the same amount of money. Pay a tuner and have a tuned bike with very little work on your part. Depends if you want to spend time learning and tuning or riding.

 

Well put Jason.

If you are wanting to do it all yourself and have anything other than stock cams I would recommend a TTS, it has a cam tune feature that is not available to the public with the Power Vision. you could get the TTS Mastertune with the communications interface that has analog inputs for wide band o2 sensors. You can get an add on kit for the Power Vision that allows you to run wide band o2 sensors as well, but you still won't have the cam tune abailable

 

Thanks, harleytuner. It took me a few times reading your post trying to decipher it. I am hoping that you read all my post completely . It seems you understand what I have, where I am coming from and what I am looking for. Not taking my post out of context. Thanks, man.

 

Lol, sorry about that, I went back and fixed all the typos. The auto correct on this phone gets me all the time. You'd think I'd learn to proof read before posting.

 

harleytuner. Can the TTSMastertune be used without O2 sensors. The reason I ask is that my 07Ultra came with O2 sensors but the previous owner replaced the header pipes with ones that do not have O2 bungs. It is no problem for me to add the bungs. 18mm wide bands? The connectors are still there. Thanks.

 

Yes you can get the standard Mastertuner II and use it without sensors. You would be relying on the canned MAP though and that could be a crap shoot on how, well it would run without getting it tuned. I was under the impression your bike was older, before they came with o2 sensors. You could save some money amd het the standard Mastertune (without analog inputs). Try a canned MAP, if you think it would need improved on you could install a set of stock sensors and Vtune it. Vtune is basically an autotune that uses stock narrow band o2 sensors. TTS has a great user manual you can download and it walks you through the process after by step, cam tune as well.

 

Would I not be better off to add the 18mm wide band sensors and go that route? If I am going to do it I want to do it right.Thanks.
