Vitacchi Clash 200
Just received my Clash 200 scooter and it's great! But the check engine light comes on/off. Saferwarehouse is no help for technical issues.
Does anyone know how to set the idle speed on the EFI throttle body and will a OBDII scanner tool read codes from the ECU? Any info at all on the EFI setup? Thanks!!! |

The owners manual has instructions on reading EFI codes.

Owners manual
Maybe you got the actual Vitacchi Clash 200 manual? I got a very generic cover all models manual that is useless IMHO. Can you post a copy of the manual you got with your Clash 200? |

Manual /Code Reader
Quote:
Forgot to mention that I picked up a cheap code reader off Amazon $12. It plugs in under the front cover and does read out some basic engine stats. I have to play around a little more and see if I can adjust idle etc. Uses Torque Lite app on your android phone. |

Check engine light: Turn off engine. Open throttle fully while turning on key. Number of flashes with 3 second interval. 1= fuel injector 2= pressure sensor 3= oxygen sensor 4= fuel pump relay 5= temperature sensor 6= idle motor 7= TPS 8= power supply 9= crankshaft missing teeth??? |

Thanks, I'll have a look and see if the scooter EFI parts match up with the manual. |

Lifan Manual
Quote:
Thanks for the Lifan Manual link. I read through it and it speaks of an idle gulp valve with an adjusting screw. My efi doesn't have a adjusting screw on the air gulp but there is a adjusting screw on the throttle body. Maybe that's it? I want to connect the ecm to my smart phone using the Lifan ecm interface software. Do you know what type adapters are needed? Isn't this fun? |

When is the engine light blinking? While cranking is a low battery issue. Can't help with idle, haven't had problem with that yet.

Check Engine On
Quote:
It doesn't blink but, comes on after high speed running. Then it goes off again. I notice a misfire when it warms up also. I may have found a solution for it. I am running some tests now SFSG. |

Zero Valve Clearance?
I thought the same thing at first, but I can hear valve clatter so it has clearance.
What I did find is that the genuineness at Lifan used a temp sensor for a water cooled engine and not air cooled. Air cooled engine run a bit hotter. So I measured the resistance of the temp sensor after a 15 minute run and then again when it is cold. The sensor reads close to 0 Ohms when hot and around 1.5k Ohms when 75 F. I put a 5k ohm 10 turn pot in place of the thermo sensor and set it at 1k ohms. Check engine light has not come on and the miss fire has gone away! Now I would like to check if the ecm is running in closed loop mode and check the map values. More to follow. Any ideas? |

Thanks for doing the research and experimentation. Yesterday I took the first ride on a warm day, 93 degrees. Ran fine but when I got back I let it idle for a few minutes while moving stuff in the garage and the engine light came on. I think you're right about it being related to the temp sensor.

After the check engine light came on I tried turning ignition off then holding wide open throttle while turning ignition on. No blinking codes, just normal. Holding the set button while turning on the ignition shows "PAS ---" so there must be a 3 digit code but what is it?
