6.2 engine programmer

[twr]

Hi use the 87 octane for the same reason, most gas stations around me only have 87,89,91 octane. I have 34.5 inch tall tires and i compaired it with my gramin gps and its very very close at 60 mph on the speedo the gramin says 59 mph. Did you enter the tire size or measure the tire and enter the size in inches? My U7194 must be a newer unit it has a 6.2 in it and it updates on the internet. My tm is on and the tire size is changed and all limits are off. I think thats all i did. I bought it mostly to change tire sizes. The cable that it uses is a serial port on the bottom of the predator unit and the other end that goes to your pc and its usb. Are you sure that yours is not updateable here is the list of the u7194 if your is not updateable that sucks.

U7194 Predator Applications are listed in the next post

Hi if you are thinking of getting better mpg i wouldn't by a programmer. If mine gives better milage its like .5 or maybe 1 mpg better. I bought mine because of my tires size, it does work and shift better with it programmed.
