Because SOTF is nothing more than an electronic throttle stop that taps into a sensor circuit that he can use as a fuel limiter based on voltage. It is nothing at all like DSP5 from EFI Live where there are actually separate tables for all of the key things in the tuning to completely change how the truck runs at any and all throttle positions. Hell, if you know what the limiting table in the stock tune looks like for the sensor you at tapping into you can set up a switch with resistors to hit voltage set points and limit fuel to what you want, even on a stock tune.

Let's just say that something better than that FAKE switchable is coming soon.... Because with these fuel temp limit styles, you might as well just run a single tune.

Yes. That's why I don't push switches on an LML. I actually don't push switches on anything. I prefer single tunes.

Iím the same way. Everyone wants a DSP5. Do people just drive WOT everywhere? Use your foot for how much power you want.

I've always only had one tune. Kill! As Anthony said; regulate with your foot.

2x

On my LB7 I had the DSP5, only because it was my first Duramax to tune. All the tunes where the same PW and throttle tables. I used it to test various timing, fuel pressure etc.

With my LMM I stuck to just a single tune. And like above, I switch tunes with my foot. It does take longer to test changes, I have about a hundred saved versions so far, but I like not having any obvious switches or tuning done.

the ONLY time i could see a switch is a DSP2 for turbo brake or not for towing. Otherwise a single tune can do it all when you put the time in and to build it right. You definitely start to see why the maps GM built for a stock truck look the way they do

I donít even need it for the turbo brake, I just donít let it come on till 2200rpm Iíll let the truck down shift before it comes on.

I actually like the dsp5 in the 05í. I dick around with the tuning and test it on the track. Easier just to switch the knob then flash the truck every pass. Big power guys can use diff tunes based on what the track will hold for power.

Everyday driving Iím in the big tune, to not piss the trans off to much.

No really. That's where throttle comes into play. It's not a light switch. Only thing Iike my dsp5 for is index classes.

Really, the throttle isn’t a light switch? Thanks for heads up.

My truck only runs 12’s so I wouldn’t know about having to much power. Are you really comparing your stripped down single cab to a ccsb street truck?
