I was lloking into getting just a single program Superchip, but when my dad uses my truck he does not want to have to put 93 octane fuel in it. I have then turned my attention to the flip chip, but my question is that when I put the chip on 87 octane program and then go back to the 93 will my computer have to relearn everything again for another 500 miles or will it work just fine? I dont want to have to wait 500 miles for my truck to be running to its full potential everytime I flip the switch. Thanks for the help.

 

Hi Beastie,

In the dual octane Flip Chip for these vehicles, it doesn't take 500 miles for the program change to start taking effect when you flip the switch.

When changing from say, the 87 octane program to the premium gas program, it's going to start taking effect right away, but will take about 50 miles or so of driving to be felt. Then it will take a couple of tanks of premium fuel to get up to the absolute *maximum* power because you will still have some 87 octane fuel in the tank when you first change over to premium gas, so that will dilute the incoming premium gas to a certain extent. We recommend running the current tank of fuel down until the low fuel light comes on (at which point you still have 3.5+ gallons left in the system), then fill up with the octane you are changing to, and then flip the switch right there at the gas station. Do it like that anytime you change octane.

When you first install the Superchip, it goes to work right away if you properly clear the ECU as per our instructions, so you'll start to feel it quickly, in teh first 20-50 miles, and it will take 350 miles or so after the initial installation of the Superchip or after clearing the ECU to get the full 100% of it's effects, as that is how long it takes for the ECU to pick up certain changes. Once you already have the Superchip installed, you'll pick up the effects in about 50 miles or so each time you flip the switch.

Just remember that you'll never make the absolute highest power on the first tank of premium, that will never happen due to the dilution effect of the existing 87 octane in the system. That oes not mean you won't get any effect, you sure will, it just won't be 100%, that's all. This means that to get the best performance, you'll want to stay on the premium gas program, and not keep switching it back and forth frequently.

The bottom line is, you'll start feeling the effects from flipping the switch within about 50 miles or so, you won't have to wait 500 miles each time you flip the switch after you've already done the initial Superchip installation. It's the first-time installation of the Superchip that will require the longest adaptation period for the ECU, in other words.

Feel free to give us a call if you want to go over this in more detail.

Have a great 4th of July,

 

Thanks for the explanation Mike. I was going to do this since I have two gas tanks ... have one tank full of premium and the other full or regular, so would this be better?????

 

Hi Beastie,

Hmmn, now there's a thought...................................

I have to confess that I've not owned a dual-tank truck personally, so I'm not familiar with their changeover operation, I.E., do they switchover automatically, or does changing tanks require making a manual change of some kind, like turning a valve, etc.

As long as you have manual control over which fuel tank the engine is getting it's fuel from, then sure, you could easily do that kind of solution, and that could work out very nicely for both you & your Dad, to make this very simple.

 

Yeah I can change tanks at will. On my dash I have a switch for "Front" and "Rear." I'm sure that the fuel line from the tank to the engine is the same one for both tanks the pump has 2 lines going in 1 going out. So I guess it will still have some of the old fuel in it until it goes through the engine, but thats alot less to dilute than a 20gal tank.

SEE now I gave you something else to think about DUAL TANKS.

Thanks for all the help Mike, now I just have to convince my dad into letting me spend anoth $400.

 

Hi Beastie,

OK, now that you describe it, that does jog my faded memory, now I remember the dash control tank switching scenario. We haven't had an F-150 with dual tanks come by in a long time.

Good luck with your Dad, & best of luck with the truck!
