For those who have 2 different tunes on a stock ecu, how do you switch between them

There's more than one way to do it, the above link shows one of them.
Another is using your gas pedal, if im not mistaken.
You can get a switch, pre-assembled, from mellon racing, buschur racing, etc. for very little money that you can hook up to your ecu.
Mine, which I put together myself, is an on/off switch.

 

Most of us are on a tephra rom and you can switch three different ways.
1)ADC0F
2)ICS button
3)TPS


or you can just go here and check it out for yourself.

^ That's what I was getting at! Lol

 

You can also wire a switch so it's obvious what mode you're in. It's easier than blowing your motor because you ran it with the wrong fuel for the map you were on

 

i have tephra mode.ignition on ,gas pedal to the floor.when ic green light start flashing im on E 85.

 

my SES light blinks fast when its on e85, and blinks slow when switching to 91

 

I have dual maps and have NEVER used the 91 oct. map. But IF I were delusional enough to want to run pee water I would simply turn the ignition to accessory mode and hold down the gas pedal for three seconds. When the CEL flashes slow I'm on 91, fast and I'm on THE JUICE. ))

 

Same here,but my engine light flashes slow-low boost,Fast-high boost.
