9r20 upgrade problem with 7194

[jozek]

on device installed 9r19, when try to update firmware to 9r20 there is no succes.. on LCD of predator message appears "Can't downgrade u7194 from 9r16 to 9r20".
What I should do to upgrade with newest revision?

how old is your u7194? im not sure but i was able to upgrade from 9r05 to 9r20 and now i cant upload tune to truck.

[jozek]

not that old, I think.. I bough it at the end of 2009. Every older upgrade went OK, but strange, the newest one had problem.

My u7194 is a 2009. Will I beable to upgrade to r20?

[mikel]

You should be OK.

[Oldviolin]

Will updating help with shift firmness? I'm at v.9r08 now

[mikel]

if you have a 6 speed trans, yes.

[Oldviolin]

I have the 4 speed. My shifting is nice at normal to moderate acceleration. At WOT I feel nothing
