hey guys the r32 i own has a APR ecu upgrade in it and it has been tuned for three setups.
(1) 95
(2) 98
(3) valet
it the manual i got with it it tells you how to change the modes. ' step 1 Press and hold the "set" button on your cruise control. After approximately five seconds, the "check engine" light on your dash will begin to blink once per second. This will tell you that you are activating program one. This blinking sequence will continue for approximately five seconds. After this five second interval, the "check engine" light will begin blinking twice per second. This will indicate that you have activated the second program. This process is continued to access any remaining programs you may have purchased. (three blinks = program three, four blinks = program four).
Step 2 Once you have activated the desired program, simply release the "set" button. The "check engine" light will stop flashing. Turn the ignition key off for 10 seconds, turn the key back on, and you will be locked in that program until you change it again.

i do this and the engine light does not come on at all. (any feed back would be swell guy cheers in advance)
