This ECM is calibrated for an EBR™ 1190RX or SX with 44-46 tooth rear sprocket and stock exhaust but with the secondary muffler removed and exhaust "tips" installed. The firmware and calibration are already loaded onto the module; no additional tools or products are necessary. This ECM is for off-road use only. See SKU 204084 for 41-43 tooth sprocket.
If you check the box above, you can send us your compatable ECM to be reprogrammed, and we will send you back the ECM with this calibration loaded onto it. This saves you the cost of a factory-new ECM.
