Hey Mike L it asked which tans tune I wanted to save so I clicked on save the one it read then I put the trans tune in I selected with modifications and it loaded flawlessly. So I’ll put the 93 tune in before I drive it again big difference in response with the trans tune paddles are way more ...

Alrighty I’ll see what it does should b here tomorrow afternoon.

Thanks I’m only adjusting the transmission tune any way right now they adjusted my fans and idle when they replaced my harmonic balancer and thermostat so I’ll just use the transmission tune

Just ordered a predator x for my 07 base corvette does it read and save the tune in the car? Or does I save a stock file from the Diablo cloud?

Measure the tire height with.a.tape measure subtract .5 enter that number as mikel suggested and go from there up or down .5 at a timetill u get it. My tires are 35.8 inches tall but My height setting is at 33.5 and the Speedo is dead accurate in refrence to my GPS in thedash.

I got it thanks

U sure. If s I'll try I tried to set the afm on in the custom tune and it wouldn't work I'll give it a shot thx

No width input only tire height measured with a tape measure the go from there

I had to put the actual tire height measured with a tape measure in to get it correct finally got it right by playing with that number up and down.

Ok I REALLY want one bad
Thanks Stan

You can't turn it off on the four speed adjust it a little at a time till u get the feel u are happy with

Use a tape measure to get the tire height enter that in the

You need to send them the PCM tunes they are what control your engine and make it run
