If you run any other parts that can change the air flow through the engine (pipes, cams), you will not have the proper fuel curve. The stage burns are calibrations for specific screamin Eagle components. Will I still benefit from the Power Commander? Q) My Harley dealer modified my Harley ECM with stage burn. With the Power Commander installed with the proper map, the air/fuel ratio at cruise will be about 13.8:1, the bike will run smoother, cooler, accelerate better and be less likely to ping or blue the pipes. However at 15:1, they can run hot, surge, ping and are more likely to blue pipes. When used with these components, the cruise air/fuel ratio is about 15:1. Q) My Harley has a stage burn with all of the recommended Sceamin Eagle Components, Why would i need a Power Commander?ДЄ stage burn is a recalibration for specific Screamin Eagle components. If you have major modifications (ported heads, aggressive cams, Stroker), then it may be best to have a custom map built by a Power Commander Tuning Centre. If you have minor modifications (exhaust, air-box, mild cams), use a map for a similar set-up. Q) I cannot find a map for my combination, what should I do? SEMA (specialty Equipment Market Association) helps protect these rights and has a web page with a list of what to do if your warranty is denied. Q) My dealer says my warranty is void because I installed aftermarket parts on my bike, what can I do?Д¬onsumers have specific rights, on any products they purchase. As the Power Commander cannot send current to the stock ECU, it is highly unlikely that it could damage the stock system in any way. In most cases, in order for the manufacturer to deny warranty for a failed component, they must prove that the aftermarket part caused the component to fail. Q)Will the Power Commander void my warranty? The Power Commander is designed so that it can not send current to the processor in the ECU, which makes it incapable of damaging the ECU.
