Brian, was discussing your EMS product with a couple buddies over breakfast one morning last weekend. Had a couple questions come up that I'd not seen answered before. Both related to potential problems while on the road.
First was can you provide an OE number for the o2 sensors used in the kit? Should something fail out in the boonies somewhere a part number that could be carried in to an auto parts store could be a help because you know any Harley shop will be useless.
Second question was on the map installed in the customer's ECM. If the customer requested it would you supply a copy of the map on disk that could be carried in the bike? Same logic as with the sensor. If an ECM craps out somewhere a dealership could at least load the map in a replacement to get you home. Wouldn't have any other changes you make. But would at least be a good base tune to finish a trip.
Great questions! Let’s address them in order. The OE number for the Bosch sensor is #17014. It is a very standard LSU 4.2 sensor and is readily available at most parts stores. The only real difference is the connection end for the harness, which is unique, but could be spliced onto the new sensor in an emergency. Let’s talk about how the bike will react if you should fail a sensor. There are fail-safes written into the system that when the ECM recognizes that a sensor has failed or even starts to provide very skewed data, the bike will revert back into open loop protective mode and keep going. Obviously it will not be running optimally but it will get you there. Then you can make a decision as to how you want to proceed. We keep 750-1000 sensors on the shelf at all times and they can be overnighted out at a moment’s notice or you can go the parts house route for the time being. As soon as the sensor is replaced, the ECM recognizes that the data is acceptable and goes right back into adaptive mode and you are on your way as before.
The second question has to do with the ECU and/or map. Because of the unique way that we code the ECU we can’t supply a map to you for you to load because the dealership wouldn’t be able to load it in the manner that we do. But before panic sets in, let me stress that the same logic holds true for the ECM as for the sensor. If you were at a dealership they could just replace the ECM with a new one and flash it to get you going for the short term. Same situation would hold true if you have a T-Max and no extra OE ECM with you or if you don’t have the equipment to reload a TTS or PC map back into the new ECM. The other option is that we have a cache of emergency ECM’s on the shelf at all times that can be programmed with your original cal file that we store on a protected server and can be sent overnight, early AM if necessary, to wherever you are in the world and you simply plug it back in a go. No trying to find a dyno, no re-learning of the system. You have to buy the ECM but we charge you nothing to re-load your system. Let me stress something though, the instance of a true ECM failure with the equipment today is extremely rare per-capita. Nonetheless, we have made every attempt before we even released this product to take into account these scenarios and provide unparalleled customer support.
