Thats easy to say if you have a shop handy who can tune it.

Most dyno tuners here down under just arent set up to tune anything above stage 2. I cant even find one with 2 oxygen sensors. So I have had to tune it myself on the strip. Thats why I wish I had a TTS. The SEPST software is clunky and inflexible.

If you are getting a shop to dyno the bike then any tuner they can use will do the job. They all do the same thing, in different ways.

 

How long is the TTS warranty?

 

Never mind I found it.

THE TURBO SHOP, INC. (T.T.S., Inc.), a California corporation warrants its MasterTune Interface to be free from defects in material and workmanship for 45 days from date of purchase.

T.T.S., Inc. warrants to the original purchaser only (customer) that at the time of delivery and to the afore mentioned time limit, the product will be free from defects or workmanship which substantially affect the Product’s performance. The extent of T.T.S., Inc. liability under this warranty shall be limited to the prompt correction at T.T.S., Inc.’s option, of any defective part which T.T.S., Inc. determines to be defective. This warranty becomes void if the product shows evidence of mishandling, dismantling, alterations, mutilation, shipping damage or repair performed by customer or any other third party without prior express written authorization by T.T.S., Inc.

This warranty does not apply to product performance, improper installation, accidents, physical or electrical stress, misuse or any other cause other than the ordinary and intended proper use for which the product was designed. This warranty does not apply to damage caused by any outside influence.

 

Like King says they all accomplish the same thing. You should pay no penalty warranty-wise for any tuner if you have a decent dealer. If your dealer tells you different, you bought from the wrong people.
That being said it's hard to go wrong choosing Fuel Moto and the PCV.

 

I think some of that clunky and inflexibility is attributed to user error sometime. I haven't had a problem at all so far the program is smooth easy to understand and manipulate, I have been learning a few tricks that have given me a bit more flexibility, the user manual is very precise and accurate it also gives more than enough information for the average person to complete a competent tuning session. If you think SEPST is clunky and inflexible you will think the same about TTS they are virtually the same.

 

Why would the PC be deficient for Stage II, III, or IV? They work for sportbikes including those used for racing, and Fuel Moto uses one for their 140hp supercharged FLH, so where's the limitation?

 

Could you explain why that is?

 

Clunky:

When you use the trending function to review a data logging session you set up the trend pens you want to see, zoom in on the time that you see the behavior that you want to tune out, flip over to the VE or timing tables and then flip back the time scale has zoomed out to the whole session.

If you want to tune multiple variables you need to zoom in, take screen shots of multiple pens and then paste them into another program so you can bring them up.

The smart tune in the SEPST is much clunkier, it doesnt let you know how much data it has collected at each VE point that it is trying to make changes at. The TTS software lets you know if it has collected enough data to be confident of the change.

Just a few examples.

 

I just know that the TTS / SEPST gives you access to the factory ECM which means you can adjust throttle progressivity, cranking fueling etc. Can the PC do that?

 

I have the Vance and Hines FuelPak on my 2010 RK. GARBAGE!!!!! Doesn't tune worth a sh!*&t, if your not a gear lower than you would normally be the curve is so flat you would swear your riding a moped. I have contacted V&H about this many times and they have changed their recommended map settings on several occasions and nothing has been helpful. Have a friend with an 09 (both are throttle by wire bikes) and he has the same problem. Finally got tired of it this weekend and ordered the Power Commander with the Autotune.
