Is anyone running 64TRRD?

[doc311]

i called SCT and talked to mike about my MPG concerns with the 1.22, so he suggested i try this tune (64TRRD_encrypted.LFU). Has anyone tried this, its a much larger file than 1.22 or 1.22 r&d?

thanks

Have you tried it yet? If so, any better results?

Thanks,

What mileage are you seeing? What do you want to see?

it think 15mpg is reasonable for highway, an 12ish for mixed. i'm currently getting 11-12 hwy.

I'm running the 1.22r&d file now and seeing 14-15 city and 18-21hwy depending on how I drive.

I tried but after loading the tune I get the "CEL", "WRENCH" and the "REDUCED POWER MESSAGE". I guess I'm back to the 1.2.2B R&D tune, great power and mileage but the shifting is very bad when you get into it. CUSTOM TUNING PLEASE!

How does a guy go about getting the 1.22 r&d tune? I am currentley running the 1.22 tune. Would like to try all that I can to see the differences.

Tony,

I'm running the 1.22B R&D with the same setup as you other than the 22.5's and if I keep it under 70mph I get 20-21mpg on the highway. I did about 350 miles on the highway last weekend and averaged 20.7mpg calculated by hand, the meter said 21.6mpg. How do you like the 21.5's?
