Tow/haul tuning

[Twinboys]

Does tow/haul modify the regular program or is it it's own program. In other words, If I get a custom tune will the tow/haul modify that new program?

It modifies. And yes the button will make shift point changes to the new tune.

 

[Twinboys]

Good to know. Is the tow-haul programming modifiable by the programmer, or does it always modify the regular program an unalterable amount?

 

[Derkperk]

What I was told by innovative when I first got tunes years ago is that the tow haul cannot be modified. If you need, get a tow tune.

I intend to get a tow tune, but I was wondering how IT would react with tow/haul off or on. Thank you, you answered my question (if you are correct). I only question that because I thought I read somewhere that the tow/haul could be modified to stay out of the highest gear.
