SOLVE YOUR SURGING PROBLEMS! The Techlusion R-259 is a Plug-and-Play post ECU fuel controller with three fuel circuits, each with itís own function and LED indicator:
* The Green LED circuit adds fuel in the low speed, used to control fuel for any cruise that occurs in open loop. * The Yellow LED is a load sensing acceleration fuel circuit. * The Red LED adds high RPM (main jet) fuel.
Each circuit has a potentiometer next to its LED which is adjusted to control the amount of fuel added in that circuit. There is a 4th pot that adjusts the closed loop add circuit. It also has a green LED. Anytime an LED is lit that particular fuel circuit is active.
Adjustment is easy, as this device will only ADD fuel. In closed loop the R-259 tells the ECU, through the oxygen sensor input, that the current mixture is too lean. The ECU responds by adding fuel until specific parameters are met. At this point the R-259 breaks off communication with the ECU and the ECU begins to lean the mixture. Once the parameter boundaries are crossed again, the R-259 once again communicates to the ECU to add fuel. Below 1500 RPM, the system functions as completely stock.
Installation is also very simple, using O.E.M connectors to connect in-line with your existing wiring harness. This is a true Plug-and-Play system designed to solve poor running issues due to the lean condition present from the factory on many new fuel injected motorcycles.
