Tuning Harley Davidson Engines
Power Commander | Screamin’ Eagle Race Tuner kits | Unichip | Harley Davidson engine tuning could easily become a long drawn out technical topic, so I’ll keep it short and simple. | There are many products on the market today to help with this seemingly complex job – Power Commander, Harley Davidson - Screamin Eagle Race Tuner kits, Plug and Play tuner kits, to mention only a few. | The problem is, the installation and the reasons for the purchase or installation in the first place. | Fuel injected HD’s – 2005 onward rely on a very simple Engine Control Unit (ECU) and even more simple components on the engine to keep them happy. | While the ignition systems are generally adequate, for most engines, the fuel systems aren’t – especially when the exhaust systems and air intake systems are modified or changed from standard. | |
| | | | Screamin’ Eagle heavy breather filter kits and Vance and Heinz exhausts are used extensively in this regard. | Very often even non-standard camshafts - Andrews, Screamin Eagle cams are added with the intention of increasing the horse power – performance, but sadly all this is normally in vain. | The fueling could be rich in one area and very lean in the other or vice versa – adding a fueler of some sort without prior proper measurement and testing not to mention setup will or can make it worse. | Careful measurement on simulated road conditions in a proper tuning shop utilizing a dynamometer is essential. | A poorly tuned engine running lean at high RPM – wide open throttle coupled to a hot running air cooled engine can be catastrophic. | Call us to arrange proper measurement before considering to purchase some sort of tune aid – we have the know how and equipment to cater for all HD tuning requirements and diagnostic trouble shooting. | | Click here to get one of our Harley consultants to advise you! | We have successfully tuned many Heritage Softtail, Fatboy, Road King, 883 Sportster, 1200 Sportser Custom, Electro Glide, Streetbob, Commander & Rocker C with our legendary tuning tool, “Unichip”. | The Dastek Unichip is not rated the best auto tune tool in the world today for nothing, it works well on Harleys as well. | | |  | | CLICK HERE TO CONTACT US | | | | | | |
