How to print values in an Interative Fashion?

Below contents are stored in an file. & i wish to use AWK for the desired output... (or a sample shell script).

Original Content.

 A 193
 A  27
 B  82
 B 496
 C 117
 D 251
 D   3
 E  26
 E 151.... and so on.

I need the above contents to be Numbered in an Interative Fashion w.r.t to its Individual Instance.

i.e. output should be 

 A_1=27
 A_2=193
 B_1=82
 B_2=496
 C_1=117
 D_1=251
 D_2=3
 E_1=26
 E_2=151.....

E 151
$ awk '{printf("%s_%d=%s\n", $1, ++num[$1], $2)}' test.txt

B_1=82
B_2=496
C_1=117
D_1=251
