I bought the C&L CAI/predator tuner combo (CL7140).

It didn't come with a user manual so I'm kind of in the dark as to whether I can/how to do this so I'm hoping you can help... After loading the canned tune (93 oct) how do I go into that specific tune to change my wheel size?

Do I choose the custom (or w/e it's called, can't remember) and do it from there? What I'm not sure about is if I do that will it remove the 93 tune and load whatever is in the (blank I'm assuming) custom tune or will it just take the wheel size change and add it into the 93?

Or am I way off and there is a way to do it from the 93 tune option? Thanks in advance for any light you can shed on this for me.

 

Choose the tune you want to install, the select modify tune, then select modify parameters.
You'll get a list of all the parameters available, go to axle ratio, then select tire revs per mile.
Enter your revs per mile, then press ESC until the Pred asks if you would like to install the tune , choose yes. Done/
