When you loaded the custom tune what did the predator have as the last tune written

the 1st time a 93 perf. tune.after that it had custom tunes on it but like i told the cmr it doesn't feel right

you have to be sure the original tune is loaded into the predator correctly. When you "send tune file to predator" it will ask you to browse for your original tune file, you MUST navigate to the area where you saved the original tune file and double click on it....if you let the software load it automaticaly it may not work correctly. My first time using a predator I had trouble with that step. even though the predator will tell you the tune is loaded into the vehicle it won't make any changes becouse the original tune is not loaded correctly.

so I guess "get the original tune file from the tool" and save it to your pc. then load the custom tune and it will ask you for the original file then....navigate to the file and select it and you should be good to go.

yea i tried that several times . i even put my truck to stock then put the canned 93 tune in which worked fine.then went back and downloaded the custom tune again to the predator but it still didnt take.

Are you getting nay errors on the dsdownloader?

no errors at all.the canned tunes load but the custom tunes will not.the only thing he noticed was if i modified the custom tune .for example i shut the mds off,tire size and throttle boost to 15% that was the only thing to change.i even tried loading the custom tune without modifying and still nothing at all.

there must be some messgae that comes up when you try to load the canned tunes...?

tune was uploaded successfully

but what does it day when you go to load it to the car?

the custom tune was successfully loaded you may unplug the predator now.

then its all good my friend....???

are you sure the custom tune is really a custom tune? post up your original tune and custom tune and we will have a look at it.

if you didn't get the original file loaded onto the predator correctly when you sent the custom tune to the predator it will show that the tune was loaded properly into the vehicle but WON'T make any changes to the vehicle.
