RMSTATOR Improved Surepower Replacement ECM Kit for Polaris Scrambler & Sportsman 400 450 500 2004-2006 | # 2203348 2203118 4011110 4010937

So surprised of the quality, perfect fit, much superior design compared to OEM and the product packaging and presentation by RMStator was really nice.

Shipping was fast and it was well raped in a box but had to put electrical tape around the wire connection to keep it from shorting out

Fist one Not suppose to charge only 12.3v at high rpms or high demand maybe got a defective one but supposed to charge at 13v to 14v minimumContacted the seller told me to send it back and now they are sending a replacement they are fast and professional when you have trouble with there products and don't mess around the solve the problem as fast as they can !

Tenía problemas con el ventilador que se quedaba encendido después de cerrar el SWITCH de Una Polaris Sportsman el Cambio de esta pieza solucionó el problema además de que me está consumiendo menos combustible que antes.

Worked great for 1 year. But quit working after only 600 kilometers.RPM's in the cluster started to jump up and down, voltage was either too high or too low.I had recently changed my battery and now has to be changed because of this issue.I would not recommend this product. Buy the oem part, it's only $100 more.
