2000 busa light load surge

[Legend]

99 and 2000 ecu's are the same......but, I've got a late 2000 plated busa thats actually a 2001 (has in tank pump different harness etc).
If your pump is outside then 2000 it is.

If you have no luck with ecus, I'd be willing to try your ecu in my 99, if that helps.
