Tire size on stock changed before Gryphon
I just recieved my Gryphon CS and have a question about existing (stock) programming. I have a friend that's a Ford mechanic and we reflashed my truck for my new tire size (went from 275/65R18 to 305/65R18) before recieving the Gryphon CS. is this considered my stock tune now? If this is my new stock tune, will it affect the Gryphon's canned tunes when i put in the tire size? or even the custom tunes when I receive them? Want to make sure that when I enter the tire size on the Gryphon that it doesn't double down on the tire size...
this has me a lil worried as I am new to this

If the tire size was flashed to the vid section of the pcm you shouldn't have anything to worry about....the CS should read it when reading the stock tune in the pcm....the only worry you might have is an unsupported hex code which may not be the case......
Edit.....one thread per subject topic please.....

got 'er all updated and installed< didnt touch the tire size n she was pretty peppy on level 2, got in and changed the tire size to 33.6 n she stuttered on accelleration n some misfiring, so changed it back to stock (think it was 29.6)
she's runnin' pretty good on level 2 but still has the putter/backfire... any thoughts? and would the cal ecm be the hex? RXCM6E7

Yes that's your hex code......
You might want to try this for the sputtering...... Load the tune of your choice Disconnect the programmer Disconnect the battery Clean the maf/with maf cleaner and throttle body/with throttle body cleaner.....optional is to change the fuel filter.....do it if it hasn't been done for awhile..... Reconnect the battery Reconnect the programmer See if this helps..... Also.....how many miles on the spark plugs?
