I have a 2001 gsr that I have had the engine built on it. I want to dyno the engine but the only dyno I have use of is just a engine dyno not a chassis dyno. My question would be what is the easiest way to hook up the ecu to the engine so I could make a pass on the dyno. Would I need just the engine harness or that plus a lower harness. Any other suggestions. I live in western ct.
