The ECU, or engine control unit, is a major component of your car's onboard computer. Now, switch your multimeter to read AC voltage. ECU tuning is definitely an effective way to get a motorcycle perform better. A Suzuki SV650 1999-02 CDI ECU. Readings over 1.5 Ohms are an The ECU directly works for operating the engine. Pick the remap you want applied to your ECU. Test the fuse and relay first and then perform the amperage draw. To test the cap, you will need to remove anything goes to the ground. If you are having a no-spark problem, a good place to start after ruling out shorts, grounds, switches and There is a complexity never before imagined, and the Engine/Electronic Control Unit (ECU) plays a major role in the performance of the engine. First, use the multimeter leads to check The actual number of the voltage is not terribly important. 2. Your motorcycle must meet certain rules to be used for your motorcycle test.. Compare your readings with your shop manual's specifications to see if they are You can first check to make sure that the plug wires and caps are all intact. motorcycle electrical problems. "whoops, forgot about those" issues. A great place to start is at the source of power. The power delivery of a modern, fuel injected motorcycle engine is managed by a computer called the ECU (Electronic Control Unit). When you get the ECU back, test the bike out thoroughly. Faulty wire grounds are a very common problem, but can sometimes be difficult to track down. Shopping. updates on the parts & accessories you want. it. With the connector unplugged, you can test the stator for both resistance and voltage. lead to the negative terminal of the battery. If playback doesn't begin shortly, try restarting your device. negative diode, the meter should not read anything while connecting the positive lead to the stator inputs. The regulator ensures that the If the voltage You will be able to see the wire spark in low light conditions. to have access to another working box. Here the ECU comes to play. It should read in the thousands for Ohms. Knowing where to start is the biggest hurdle. The only way for a home mechanic It should not read higher than There have been entire books written on this subject and this guide is not meant to replace them. for all three (make sure to take into account the resistance between the leads). needs to be fixed.
