(Diablo) Tuners & Tow/Haul

[WulfGang]

So I was just thinking about ya know, stuff...

And I started wondering that when in tow/haul mode does this cancel out the Tuners installed shift points, timing, etc, when in use?

 

[WulfGang]

All I know is I didn't ever use it on my last tow.

The result was a nice shift pattern by HemiFever.

I dont think pushing tow/haul will cancel out any tuning. I do know that T/H has different separate shift schedule programming than your normal drive shift schedule. Did you tow with a 91 performance type tune and did hemifever tune your transmission shifts?

I couldn't get the HF fuel tune to load into the DS.

The HF trans tune did, however.

Yes. I ran the tran tune with a 93 canned tune.

I'm on the other side with superchips 91 performance and trans tuning. I'm sure that my user part throttle shift schedule I created will tow much better than stock and stock T/H shift points. I also believe towing with my user created shifts holding on longer and tuned to 91 performance is superior to SCs tow tune. Tow tune tends to be boggy. Sorry I can't comment on Diablo tunes since I never experienced it.
