1715 Troyer Supertuner
1715 Troyer Supertuner
Hey guys, I am hoping someone can shed some light on this for me. About 4 or 5 years ago (I am guessing at that) I got a tuner from Troyer Performance. Now we have the Ethanol based gasoline and I am being told it does not combust in the same exact manner as gas used to. So I am wondering if my tuner requires a tweaked program for best performance or if this is a load of bs. Anyone heard anything about this?
Thanks!!
Thanks!!

The canned tunes can't be 'tweaked' anyway.
Running 10% eth (Sunoco 94) here on a TP-Tuned Xcal2. No probs with 'combustion', or power.
Exactly - if you are running what we used to call "gasohol" - which has 10% ethanol - then both your factory tune and that tuning in that Superchips unit will be OK.
What you CANNOT do is run the E85 stuff.
Now technically, the stoich point changes from 14.64:1 to 14.13:1 with 10% ethanol fuels, so if someone orders custom tuning from us and says they are using 10% ethanol fuel on a NON FLEX-FUEL VEHICLE, then we change that stoich point so that the A/F's will still be dead on.
But vehicles are required to be able to run on a maximum of 10% ethanol by volume from the factory, even if they are not "flex fuel" - so you'll be fine using what we call "gasohol."

Don't understand what you just said, but it sure sounds cool. Guess thats why the custom tunes give the best gains. 
Here ya go ...

Now in normal cruising around at less than about half-throttle or so, no, the ethanol won't make any difference other than reduce fuel mileage a little bit, as the system can compensate in closed loop for that amount of difference - it's when the engine is under a heavy load, operating in open loop, than it would lean out a bit with ethanol blended fuel like E-10, or what we use to call "gasohol."
If you would like to have your tunes adjusted, you need to give us a call and we can look you up to see how long ago they were done and what it would cost to have us make that adjustment for you, if you like - just give us a call at our number listed below.
