How many AFR channels does a Dynojet dynamometer have?
One AFR channel – This is standard issue with Dynojet dynamometers but limits accurate Harley tuning since the operator has to adjust the AFR of both cylinders while only measuring one.
What does dr.dyno want from a Harley Davidson?
When a Harley comes off the Doc’s dyno, he wants you to have: Silky smooth power at all throttle openings. Good fuel mileage, typically 42-45 at reasonable highway speeds. Very little or no decel pop. Cool running at low speeds. But what if you can’t hook up with the Doc to get your Harley all dialed in?
How many AFR channels does a Harley Davidson need?
Two AFR channels – THE way to go, especially for Harleys. It allows the tuner to continuously monitor the second cylinder and tune it individually as needed. The number of dyno runs the bike is subjected to and the total tuning time are cut nearly in half.
Can a dyno be used to tune a Harley Davidson?
A Harley has two cylinders. The air/fuel ratio (AFR) needs to be measured and tuned in both so if the dyno has: No AFR sniffer – it’s only useful for maximum horsepower and torque measurement. It CANNOT be used to tune fuel injection and may only be a prop for a ripoff scheme.
