How to determine if ECU is original or "upgraded"?
I have an '04 Vee with 16k miles. For a while, it's stuttered/stammered, in rhythm, from around 3,200-3,600 RPM....when lugging a little, as I roll on the throttle. I THOUGHT it was the dreaded chudder. But, I shimmed all springs in the clutch, and this had 0 effect. So, after much research and reading, I've found several people who describe the exact same symptom, and who said it 100% went away after they changed their ECU.
So, to start, I will need to determine if my ECU is stock or "upgraded". Then.....if stock, I wonder if I have a shot in hell of getting it upgraded by Suzuki, now? I mean, there was a recall (I think?) on my year's ECU.
Thanks in advance!
